Abstract

Azimuddin Md., Alam Q.M. and Baset M.A. 2009. Potato for Food Security in Bangladesh. Int. J. Sustain. Crop Prod. 4(1):94-99. A survey was conducted at Comilla and Munshiganj districts during 2008 to generate information on area, production and utilization of potato. Both primary and secondary data were used in this study. A total of 100 farmers were selected randomly. Data were collected by direct interview method. Area and production of potato have been increasing rapidly compared to cereal crops like rice and wheat. Per unit of land and time potato was more productive than any other food crops. Average yield of potato was 22.25 t/h. Maximum yield was 36.23 t/h at Munshiganj. Average production cost and selling price of potato were Tk 6.95 and 10.95 per kg respectively. Benefit Cost Ratios (BCR) was 1.58. Potato contains about 16% carbohydrates of which starch is the major part i.e. about 14% starch on fresh weight basis. The potato is not an outstanding source of energy yet a good source of high quality protein. Potato is a rich source of vitamin C, it is rich in important minerals. Results showed that Potato is an efficient food crop. If percentage of potato consumption is increased pressure on rice would be reduced. Hence potato can play an important rule in the food security of Bangladesh.

... Productivity and profitability of potato cultivation in the study areas are given in Table 3. The productivity or yield of potato in all areas was 23.12 ton/ha which is higher than the national average yield of 16.0 ton/ha (BBS 2008), but close to the average farm level yield (22.25 ton/ha) of Comilla and Munshigonj (Azimuddin et al. 2009). Average gross return, gross margin and net return in all the study areas were Taka 346,800, 168,849 and 154,485 per hectare respectively. ...
... The estimated BCR of this study was lower but, close to the result presented by Hoque et al. (2006) 2.41. Also average BCR for potato production in Comilla and Munshigonj was presented by Azimuddin et al. (2009) 1.58 which is lower than that of the present study. ...
... Average farm size in the study area was 1.76 ha, cropped area 1.14 ha in which average potato cultivated area was 0.81 ha. The average production per farm house was 17.64, tons and yield was found to be 23.12 ton/ha which was higher than the national average yield of 16.0 ton/ha (BBS 2008), but close to the average farm level yield (22.25 ton/ha) in Comilla and Munshigonj (Azimuddin at al. 2009). ...
... It has gained industrial use in production of starch, crisps and chips due to increased urbanization worldwide [1]. The crop yield per unit area and nutritional value are relatively higher compared to cereal grains [2]. The global and Africa annual potato production is estimated to be 377 and 25 metric tonnes respectively. ...
... Most small-scale farmers depend on it as a source of income. About 800 000 farmers grow potatoes, with an estimated 2.5 million people working in the potato sub-sector as transporters, market agents, processors, exporters, etc. [2]. ...

Poor soil fertility is among the significant constraints to potato production in Kenya. Increased potato production currently depends on the use of chemical fertilizers for nutrients. The prices of chemical fertilizers continuously increase, becoming unaffordable for small-scale farmers who mostly grow potatoes. Therefore, the continuous use of chemical fertilizers such as NPK may cause complete depletion of other macro and micronutrients in potato production areas of Kenya. In addition, it increases the cost of inputs and triggers environmental pollution. The objective of this study was to evaluate alternative soil amendments using different biofertilizers in potato production. Two field experiments were conducted during the 2019 and 2020 seasons using two potato varieties (Shangi and Kenya mpya). The treatments were 30 t ha-1 of farmyard manure (FYM), two different biofertilizers (Trichoderma asperellum, T.R., and Bacillus subtilis, B.A.) applied at a rate of (150 mL/10 kg) and NPK (0 and 100 kg ha-1) as negative and positive controls respectively. Field experiments were carried out in randomized complete block design in a split-plot arrangement. The results indicated that FYM+TR increased potato yield and plant height by 19.81% and 18.99%, respectively, compared to the control. FYM+TR also increased tuber dry matter, marketable tuber weight, and potato grade by 25.15% 18.99%, respectively, compared to the positive control. The study recommends using FYM+TR and FYM+ BA for potato production in Kenya as they were found to increase crop performance and subsequent yield, which is beneficial to the environment and safe for farmers.
... The lower returns with 15 th and 30 th September were on account of lower yields due to higher temperature. Higher cost of planting material (Azimuddin et al. 2009) [3] and increased cost of cultural practices were main cause of high cost of potato cultivation. Similar trend was observed with B:C ratio though it was same with 15 th October and 30 th October planting windows. ...

Field experiment was conducted to study the performance of potato CV. Kufri Khyati to aberrations of temperature and rains in relation to production and incidence of disease and pests at Central Potato Research Station, Gwalior, India. Potato cultivar Kufri Khyati was planted with four planting windows viz 15-12. Data revealed that early planting of potato CV. Kufri Khyati at higher temperature delayed tuberization, reduced tuber number (259,000/ha) and finally there was a drastic reduction in tuber yields (9.5 t/ha) with net returns showed negative (Rs 14612/ha) trend. The B: C ratio was also less than 1 in 15 th September planted crop along with higher incidence of mite, thrips and stem necrosis disease. The highest N uptake (92 kg/ha) was recorded with 15 th October planted crop, however it was lowest with 15 th September planted crop. The highest nitrogen use efficiency (182 kg tuber/kg N applied) and water use efficiency (109 kg tuber/mm water) was recorded with 15 th October planted crop with low incidence of pests and diseases. Severe mite, thrips and stem necrosis disease incidence were recorded in 15 and 30th September planting window of potato. Thus, the planting window of 30 th October is the most suitable planting date for potato cv. Kufri Khyati for ware crop to get maximum tuber yield, low incidence of mite and thrips and higher net profit in Central India.
... The onset of the global food crisis in 2008 was, for Bangladesh, a matter of triply unfortunate timing: excess flooding and Cyclone Sidr in 2007 had reduced the harvest by almost two million metric tons (World Bank 2010); national foodgrain reserves had been run down, in line with policy recommendations by the World Bank (Islam 2012;Chowdhury, Farid, and Roy 2006); and the country was being governed by an unelected caretaker government (Ahmed 2010). As the global financial crisis unfurled around the world, workers in the flagship readymade garments industry had already been protesting low wages and breaches of labour rights since 2006 Siddiqi 2017). ...
... A popular political theory heard around the 2008 crisis was that the government was responsible for protecting its people against food shocks; it would do so not out of great love for its people, but because of simple democratic pressures-exerted, if necessary, through direct action, electoral or protest (Hossain and Kalita 2014;Hossain and Green 2011). The coincidence of the tenure of the caretaker government (January 2007-December 2008) with the rising rice price lost its popularity, and confirmed the idea that military governments were inherently less capable than 'political' governments of protecting the population against food crises (see (Islam 2012)). The US Embassy reported on the worries of an unelected government, highlighting in particular the grievances of garments workers: ...
... So the continuous increased demand insists to produce huge amount of potatoes. In addition, potato is a high productivity crops (Azimuddin et al., 2009) and helpful to eradicate hunger from Bangladesh to achieved Millennium Development Goals within 2015 (Hossain and Abdullah, 2016). ...
... Sometimes it becomes less than 70 percent of its original size (Walker et al., 1999). About 2-9 percent of cold stored potato affected by diseases (Khan et al., 1973) which is equal to 80 million Bangladeshi currency/ taka (BDT) (Azimuddin et al., 2009). These diseases occur in the cold storage due to over density because freeness of the diseases of potato depends directly proportional to its preservation space Suarez, 2011, 2012). ...

Potato (Solanum tuberosum), is the most consumed vegetable in Bangladesh throughout the year round. Due to the suitable environment, potato production is increased day by day and in 2019 Bangladesh became the seventh largest potato producing country in the world. Now the amount of production is more than the demand and hence from recent few years Bangladesh starts to exports potato and its associated food products to the different countries in the world. Unemployment problem is very common in the developing countries like Bangladesh but potato gives an opportunity to solve the problem and also help to eradicate the situation of hunger. Though bumper harvest of potato is very common in Bangladesh but the growers are sometimes devoid of to get the fair price due to the extreme margin by the middlemen. Hence, the aim of this study is to examine the present situation of potato production, storage, marketing system, and export. The major findings of this study are as follows: Firstly, poor transportation system, inadequate storage facilities, lack of capital, lack of knowledge of farmers about market price, illiteracy, and syndicate system of middlemen are some key factors for inefficient marketing system of potato in Bangladesh. Secondly, giving the increased important in potato is not the ultimate solution, instantly improve the marketing mechanism of potato is required for Bangladesh. Finally, it is exigent that government needs to take the obligatory steps for the sustainable production and marketing system of potato in Bangladesh.

... With the introduction of modern varieties and appropriate management techniques, this production can be doubled. It is also possible to increase potato production both vertically and horizontally (Uddin et al., 2009). Low quality seed is one of the major problems for potato cultivation in Bangladesh (Hossain et al., 2011a). ...
... There are scopes for further improvement of the potato sector in Bangladesh through the use of quality seed potatoes, quality inputs including fertilizer, pesticides and proper crop management. A number of studies have addressed these issues along with possible recommendation for enhanced potato production (Fraley et al., 1983;Hanemann and Ahmed, 2007;Uddin et al., 2009;Uddin et al., 2010;Mian et al., 2013;Anonymous, 2014). However, to improve the situation the following steps can be taken: ...

Potato (Solanum tuberosum L.) is an important vegetable that plays a vital role in global food and nutritional security and alleviation of poverty, especially in Bangladesh. Although, the soil and climatic conditions of Bangladesh are favourable for potato cultivation, every year production is hampered due to use of low quality seeds. Seed potato industry is developing in Bangladesh. However, only 5-10% quality seeds are being produced and used by the potato farmers. Quality seeds alone can contribute to increased yield by 15-20%. Both public and private sectors together supply only 5% quality seed potato and the rest 95% is almost of low quality produced by the farmers themselves. In prioritizing different issues of agriculture, challenges of production and supply of quality seed to the farmers should be considered as a top priority issue. For increasing quality seeds, the whole seed system needs to be reviewed. The present work was an attempt to review the seed potato production systems, supply system and also to identify the possible challenges and policy implications in regards of the problems on seed potato in Bangladesh.
... The cropping sequence means that potatoes are often grown with sub-surface water still left after flooding the rice, enabling potatoes to benefit as well from residual soil nutrients still present from fertilization of the rice crop (Scott, 1988). Most importantly, given the high yields and the short vegetative cycle, potato cultivation is a "commercial crop" in much of Asia in that the bulk of production is harvested for sale and eventual use off the farm, even by small growers harvesting less than half a hectare (Scott, 1988;Azimuddin et al., 2009). Recent research indicates that more could be done to improve productivity and profitability by more efficient use of available inputs (Hossain et al., 2008;Baset et al., 2009). ...
... Over the last several decades, numerous studies have identified the high cost of planting material as a main cause of high cost of potato cultivation (Scott, 1988;Xie et al., 2007;Hossain et al., 2008;Azimuddin et al., 2009). Given that finding and that potato is most often produced as a cash crop in the developing countries of Asia, growers have had strong incentives to economize on seed use. ...

Potato production in the developing countries in Asia now accounts for a greater share of global output than all the industrialized countries combined. This paper examines the divergent peaks, valleys, and spikes in output that characterized the 120 million t expansion in potato production in Asia during the last half century. New technology, improvements in production and postharvest infrastructure, and government policy along with the inherent traits of the crop itself all contributed to these trends. A shift toward more diverse diets and the cash income derived from potato production played an equally, if not more important role. After assessing alternative scenarios for future development of the potato sector in the region, the paper concludes by highlighting opportunities for industry before identifying some key topics for future research.
... Besides adopting high yielding and hybrid varieties, management practices should be improved. It is possible to increase potato production by vertical and horizontal expression (Uddin, 2009). ...
... But average potato yield was 22.25 t/ha for both the locations Comilla and Munshiganj in 2008 (Uddin, 2008). Average potao yield of these locations (Comilla and Munshiganj) was 20.50 t/ha, whereas individual average yields at Comilla and Munshiganj were 16.23 and 24.78 t/ha, respectively, in 2005 (Uddin, 2009). Due to late blight yield was very low in the northern part of Bangladesh in 2009. ...

The study was conducted to build the union level digital database and maps of potato during 2008-09. Both primary and secondary data were used in the study. Data were collected from all blocks of four upazilas of four districts and farmers' level. Union, upazila, district, and country level digitized maps of Bangladesh were used in the programme. GIS, GPS, and MIS related IT were used in the study. Out of total cultivable land (1,00611 ha) in four upazilas, potato cultivated area and production were 27,414 ha and 3,32,424 t, respectively. Eighteen (18) varieties of potato were cultivated in the study areas, among them 13 were HYVs and 5 were local varieties. Out of 41 HYVs of potato developed by BARI upto 2008, 13 were cultivated in the study areas. Maximum (89.7%) area of HYV potato was covered by Diamant, Cardinal, Granola and Multa. At Chandina and Gozaria, potato area was only cultivated by HYVs. Shibganj and Pirganj shared 64 and 61% potato areas, respectively under HYVs. Average potato yields of these upazilas and Gozaria were 14.34 and 24.36 t/ha, respectively, during 2008-09. Production cost and selling price were Tk. 8.73 and 11.56 per kg, respectively at the time of harvest in 2009. Benefit Cost Ratio (BCR) of potato was 1.32 and maximum was 1.37 at Pirganj. Besides adopting high yielding and hybrid varieties, management practices should be improved. It is possible to increase potato production by vertical and horizontal expression (Uddin, 2009).
... Production of potato has been increasing rapidly compared to cereal crops like rice and wheat (Azimuddin et al., 2009). Potato cultivation under the institutional loan was a profitable business (Majid, 2004). ...

The study assesses the profitability of potato cultivation in some selected areas of Sylhet district in Bangladesh. A total of 50 farmers were selected from different villages of Fenchugong upazila in Sylhet district. Both tabular and descriptive techniques were used to analyze the collected data. Average family size was 6.24 which was found to be higher in large farm followed by small and medium farms. On an average the dependency ratio was 3.22. The literacy in the study area was higher than that of national average of Bangladesh. Agriculture was found to be dominating occupation among the inhabitants. On an average 50% of the total income obtained from potato production. The annual savings of the sampled farmers was found to be higher in large farm followed by medium and small farm. On an average hectare-1 cost of production of potato was Tk. 1, 94,114. The average hectare-1 yield of potato was 17194 Kg. The highest yield was obtained by large farms (18291 kg ha-1) while it was the lowest in small farms (16804 kg ha-1). When all costs were taken into account the average net return was observed to be Tk. 81336. On an average BCR was the highest in large farms (1.68) appearing lowest in small farms (1.34). The study identified some major problems like non-availability of quality seeds and high price, low market price, shortage of human labor, lack of storage facilities etc. The farmers opined that potato production would be economically viable if quality seeds with affordable price, marketing facilities with standard price, storage facilities, fertilizer and insecticides with reasonable price are ensured.
... Although, cost of cultivation remained maximum in paired row bed planting, due to higher seed cost. Higher cost of seed and management practices are main cause of major reason for high cost of potato cultivation (Azimuddin et al. 2009). 30 th October planting with Kufri Khyati recorded highest gross return of ₹228,900/ha at 90 days harvest (Singh et al. 2017). ...

The present experiment was conducted during 2020-21, 2021-22 and 2022-23 at Regional Station, ICAR-Central Potato Research Institute, Gwalior, Madhya Pradesh to evaluate the best spacing combination and dehaulming time for enhancing the seed size potato (Solanum tuberosum L.) tubers and profitability under north-central plains of India. Experiment was conducted in a split-plot design (SPD) comprised of 5 spacing combinations, viz. S 1 , Ridge and furrow 60 cm × 20 cm (Control); S 2 , Ridge and furrow 60 cm × 15 cm; S 3 , Flatbed paired row 90 cm bed width (two rows at 40 cm × 20 cm plant to plant spacing); S 4 , Flatbed paired row 90 cm bed width (two rows at 40 cm × 15 cm plant to plant spacing); and S 5 , Flatbed triple row 90 cm bed width (three rows at 20 cm × 20 cm plant to plant spacing) in main plot and 2 haulm killing dates, viz. 70 and 80 days after planting in sub plots. The treatment S 5 , Flatbed triple row 90 cm bed width (three rows at 20 cm × 20 cm plant to plant spacing) spacing combination significantly increased the number and weight of seed size tubers, net seed size and total tuber yield when dehaulming was done after 80 days. The highest increase in seed size and total tubers over control reported when dehaulmed at 70 days. However, the treatment S 3 , Flatbed paired row 90 cm bed width (two rows at 40 cm × 20 cm plant to plant spacing) with 80 days haulm killing recorded highest seed size tuber 58.03% and benefit cost (B:C) ratio of 2.51:1 among all other treatment combinations. Though, treatment S 3 i.e. flatbed paired row 90 cm bed width (two rows at 40 cm × 20 cm plant to plant spacing) with 80 days haulm killing combination require higher seed rate but can be an economically viable option for enhancing seed size tuber percent and B:C ratio.

Multilocation trials are usually performed in breeding and variety evaluation programs to identify stable genotype(s) with similar crop performance in various environments. The present study evaluated the stability of six selected potato varieties (BARI Alu-7, BARI Alu-8, BARI Alu-25, BARI Alu-28, BARI Alu-36, and BARI Alu-41) suitable for multiple locations (Barishal, Bogura, Cumilla, Jamalpur, Jashore, Munshiganj, Mymensingh, and Rajshahi) in Bangladesh from 2014 to 2019. The study considered genotype and environment as treatments, year as replications and used a randomized complete block design (RCBD) with to construct the genotype plus genotype-vs-environment interaction (GGE) model. The joint analysis of variance revealed significant differences among the genotypes and environments (GE). The scores of PC1 (principal component 1) and PC2 (principal component 2) cumulatively explained approximately 63 % of the total variation in GE interactions and were used to construct the GGE biplot. BARI Alu-8 and BARI Alu-28 were the best genotypes, with high average yields and high stability across the locations. Jamalpur and Munshiganj was identified as the desired locations among the tested environments for growing all the genotypes. This study will help potato growers select highly stable high-performance varieties for a particular environment to achieve maximum tu-ber production.

Background Potato is a staple food and a main crop of Bangladesh. Climate plays an important role in different crop production all over the world. Potato production is influenced by climate change, which is occurring at a rapid pace according to time and space. Objective The main objective of this research is to observe the variation in potato production based on the discrepancy of the variability in the spatial and temporal domains. The research is based on secondary data on potato production from different parts of Bangladesh and five major climate variables for the last 17 years ending with 2020. Methods Bayesian Spatial-temporal modelling for linear, analysis of variance (ANOVA), and auto-Regressive models were used to find the best-fitted model compared with the independent Error Bayesian model. The Watanabe-Akaike information criterion (WAIC) and Deviance Information Criterion (DIC) were used as the model choice criteria and the Markov Chain Monte Carlo (MCMC) method was implemented to generate information about the prior and posterior realizations. Results Findings revealed that the ANOVA model under the Spatial-temporal framework was the best model for all model choice and validation criteria. Results depict that there is a significant impact of spatial and temporal variation on potato yield rate. Besides, the windspeed does not show any influence on potato production, however, temperature, humidity, rainfall, and sunshine are important components of potato yield rate in Bangladesh. Conclusion It is evident that there is a potential impact of climate change on potato production in Bangladesh. Therefore, the authors believed that the findings will be helpful to the policymakers or farmers in developing potato varieties that are resilient to climate change to ensure the United Nations Sustainable Development Goal of zero hunger.
... There are close to 4000 varieties of potato with specific agricultural or culinary attributes. Potato is considered to be the most important agricultural plant in the world producing the highest dry matter and nutrient content per unit area of land, higher than those of the major cereals (Azimuddin et al. 2009). According to FAO estimates in 2019, over 370 thousand tonnes of potatoes were produced worldwide from 17 million hectares. ...

Potato is the most consumed vegetable across the world. It is a highly nutritious crop constituting important nutrients such as vitamin C, B6, iron, potassium, antioxidants, phytochemicals and dietary fibre that are essential for human health. Despite being loved by most people, there are many speculations about its impact on health, due to its high glycemic index. Potatoes have been tagged as causative agent for obesity and type 2 diabetes. Hence, this review provides a comprehensive view of the potato’s nutrient content, its variation due to genotype, environmental factors and different methods to minimize nutrient loss during storage and cooking conditions. Additionally, insights into various approaches for reducing the glycemic index and the potential of potato to tackle energy requirements and malnutrition for current and future generations are also discussed.
... Due to travel restrictions, potato samples could not be analyzed for protein and micronutrient content. The standard protein amount of 20% of the fresh potato yield was taken from literature (Azimuddin et al., 2009). Based on the amount of the yield obtained, the protein content obtained in each treatment was estimated and converted to ha. ...

A field experiment was conducted for two consecutive years 2018-19 and 2019-20 with high bulking early potato cultivar Kufri Khyati at Central Potato Research Institute, RS, Gwalior in split plot design with six planting geometries as main plots viz S1-60√20 cm (Control), S2-66√15 cm, S3-66√20 cm, S4-75 √15 cm, S5-75√20 cm and S6-paired row and three haulm killing dates as sub plots viz 70, 80 and 90 days after planting. For growth parameters, only planting geometry 66√15 cm recorded significantly higher plant height (52.6 cm) over other planting geometries.75√15 cm (52.6) and 75√20 cm (50.2) planting geometry recorded non significant but higher compound leaves/plant over other plant geometries. Days to haulm killing did not influence the growth parameters viz, stem, compound leaves and plant height. Significant increasing trend was recorded for number and weight of seed size and total tubers with increasing planting geometry over wider plant geometry 75√20 cm (285 thousand/ha, 17.41 t/ha seed size tuber and 671 thousand/ha, 34.52 t/ha for total tuber) and highest was recorded in paired row planting (487 thousand/ha, 29.52 t/ha seed size tuber and 1040 thousand/ha, 45.93 t/ha total tuber). Paired row planting with 70 days of haulm killing recorded significantly highest seed size (516 thousand/ha) and total tuber number (1092 thousand/ha). By number 60√20 cm planting geometry at 80 days of haulm killing (51.15% and 0.957) and by weight paired row planting at 70 days of haulm killing (73.15% and 0.367) recorded significantly highest seed size tubers percent and best seed: non seed ratio over other factor combinations.

Socio-demography of statuses reflects the demographic and social roles and achievements of an individual(s) in a population. The current profile of socio-demographic on potato growers is vital to know for sustaining of a major demandable vegetable, potato. The purpose of the present study was to determine the status of socio-demography in Chapainawabganj district. Using a random sample procedure, a total of 40 respondents were selected on six socio-demographic characteristics like as, age, level of education, experience level, farm size, family size and annual income. Data were collected from five upazilas in Chapainawabganj district (Bholahat, Gomostapur, Nachol, Shibganj and Chapainawabganj sadar) using a pre-structured interview schedule. Middle aged (36 to 50 years) potato farmers having primary education and 11 to 25 years' experience in potato farming. They have medium sized farm (1.1 to 3 ha) living in a medium sized family (5 to 7 persons) and medium annual income (32 to 302 thousand Taka). Form the above indication, it was clarified that the features of socio-demography was not a mark to sustain potato farming system.
... In the Indian sub-continent, the cultivation of potatoes was probably started during the 17 th century [11]- [13] and in Bangladesh, it was introduced in the late 19 th century [9], [14] - [18]. Production of potatoes has been increased day by day due to the geographical suitability [3], [19]- [21] and the demand of lower-income people of Bangladesh [17], [22]- [24].

This study aims to analyze the supply chain of potatoes and determine the factors affecting postharvest losses of potatoes at the producer level of Bangladesh. Data were collected through a face-to-face interview schedule from a sample of total 60-30 farmers, 6 wholesalers, 5 aratdars, 5 retailers, and 14 consumers in Sirajdikhan and Sadar Upazila of Munshiganj district. Descriptive statistics (percentages, frequencies, etc.) and multiple linear regression analysis were used for this study. The result shows that channel 4 is the longest marketing chain in the study area which includes the marketing actors-farmers, aratdars, wholesalers, retailers, and consumers. In the supply chain of potatoes, the amount of postharvest loss is 6.6% for the producer's level, 5.3% for the wholesale level, 1.10% for the aratdar level, and 2.1% for the retailer level in the study area. The regression model reveals that age and amount of production have a significant positive relationship, while experience has a significant negative relationship with the postharvest losses of potatoes. The study also shows that lack of storage facility (48.94%) and poor packaging system (32.73%) are the major reasons for occurring postharvest losses of potatoes. The farmers and intermediaries suggested that it is necessary to identify the maturity stage of potatoes at harvesting time (70%), improve the cold storage facility (56.67%), and improve the loading and unloading system (56.25%), etc. for reducing postharvest losses of potato.

The growth of cities in developing nations often comes with high levels of unemployment, food insecurity and increased poverty. Hence, this study aimed to assess the contribution of potato farming activities by urban dwellers towards the alleviation of these socioeconomic problems in Jos. The study used mixed methods to collect data from 71 respondents which were analysed quantitatively and qualitatively. Results showed that women dominate the potato production within the city of Jos. Furthermore, participating farmers exhibited a high level of education, with good level of experience in potato production. Results have confirmed that potato farming in the city of Jos is an important strategy to provide employment opportunities, income and food security for the growing population. However, the respondents identified the lack of capacity building, access to credit facilities, limited availability of irrigation water during the dry season and costly farm inputs and farm equipment as major constraints in the production of potato. According to most respondents, potato production affects the ecological balance of the city environment. It is therefore recommended that agricultural extension workers should develop the capacities of farmers on modern potato farming practices. In addition, farmers should also form a farmer cooperative to enable them access credit facilities from lending institutions.

A collection of one hundred tetraploid potato accessions was evaluated in relation to the concentrations of nine minerals (Fe, Zn, Cu, Mn, Ca, Mg, S, P and K) required for human nutrition. Large amount of variability for selected minerals was observed in the germplasm. Significant positive correlations (P < 0.001) were found between Fe- Cu (r2=0.41), Zn-Cu (r2=0.46), Mn-K (r2=0.51) and Ca-Mg (r2=0.40), whereas significant negative correlation (P < 0.001) was observed between P-K (r2= -0.36). The first two principle components accounted 42.72% of the total observed variations. Unweighted pair group method with arithmetic mean (UPGMA) based clustering distinguished the potato accessions into different groups based on Gower distances. These results will be useful for developing biofortified potato varieties using traditional and modern breeding methods. Moreover, variations in the mineral contents within the potato germplasm could also be used for the identification of molecular markers associated with mineral concentrations through genome wide association studies (GWAS).

Potato production is becoming one of the major profitable crops among the famers in the northeastern part of Bangladesh. This study investigates the occupational status, land tenure arrangement, household income scenarios, and estimates the level of costs and net income variation for potato production in the greater Sylhet areas of Bangladesh by using the both descriptive and statistical techniques. The descriptive results exhibit that most of the households involved in farming as well as other income generating activities; however, the highest income share comes from the household business followed by agricultural activities. Near about half of the farmers belonged from the small category (46.39 percent) and around 37 percent were pure tenant while 30 percent were mixed tenant involved with both sharecropping and cash lease farming. Nonagricultural income and remittance are the key income sources of employment that influence the average per capita income. Agriculture share was approximately 9 percent in total household income where rice dominates the major share and potato does not have significant contribution. However, seed, irrigation, fertilizer, and hired labor cost were the major cost components for potato cultivation. This study also decomposed the variance of net income into different factors and found that gross income difference exists among the farmers due to the fertilizer and seed cost variation. Gross income explained the net income variation, which implies that potato yield or potato price (quality) or both vary widely among the farmers. This study can contribute to making links between the shares of farm household income that would be helpful for policy makers to understand the causes of cost and income variation as well as opt for better strategies to support the farmers.

The study assesses the profitability of potato cultivation in some selected areas of Sylhet district in Bangladesh. A total of 50 farmers were selected from different villages of Fenchugong upazila in Sylhet district. Both tabular and descriptive techniques were used to analyze the collected data. Average family size was 6.24 which was found to be higher in large farm followed by small and medium farms. On an average the dependency ratio was 3.22. The literacy in the study area was higher than that of national average of Bangladesh. Agriculture was found to be dominating occupation among the inhabitants. On an average 50% of the total income obtained from potato production. The annual savings of the sampled farmers was found to be higher in large farm followed by medium and small farm. On an average hectare-1 cost of production of potato was Tk. 1, 94,114. The average hectare-1 yield of potato was 17194 Kg. The highest yield was obtained by large farms (18291 kg ha-1) while it was the lowest in small farms (16804 kg ha-1). When all costs were taken into account the average net return was observed to be Tk. 81336. On an average BCR was the highest in large farms (1.68) appearing lowest in small farms (1.34). The study identified some major problems like non-availability of quality seeds and high price, low market price, shortage of human labor, lack of storage facilities etc. The farmers opined that potato production would be economically viable if quality seeds with affordable price, marketing facilities with standard price, storage facilities, fertilizer and insecticides with reasonable price are ensured.
... This is premised on the fact that encouraging small scale sweet potato farmers to adopt the use of improved cultivars and production technologies will boost sweet potato production and enhance food security especially among the rural people.

Abstract This study analysed factors influencing the adoption of improved sweet potato technology in Kwara State, Nigeria. Purposive sampling was used to select four villages that have been dedicatedly involved in sweet potato production for a period 5 years. Data were gathered through the administration of interview schedule to 20 randomly selected potato farmers from each of the 4 villages given a sample frame of 80 farmers. Descriptive statistics such as frequency counts, percentages, means and standard deviation were used to analyse the results of the study. Results revealed that majority of the respondents were in their middle age (42.5%) 41-50 years; 66.3% were male, 90% were married, 51.3% have no formal education. While 75% have farming as their primary occupation. The level of constraints faced by extension agents in meeting training needs due to poor extension contact had the highest mean value of 2.30 with standard deviation of 0.74. Chisquare result revealed that educational level, land tenure system, membership of cooperative society and contact with extension agents have X2 value of 11.309, 15.235, 7.182 and 19.445 respectively and all significant determinants of adoption of improved production technology of sweet potato at p< 0.05. On the basis of these findings, it is recommended that improved extension contacts will boost farmers’ understanding of the innovation as well as their decision to adopt.

p>Potato is the third largest food crop in Bangladesh by tonnage of production. Its acreage and production are also increasing in day after day. This study was accomplished to examine the profitability and resource use efficiency of potato cultivation in five upazilas of Munshiganj district of Bangladesh. A total of 52 farmers were selected randomly from the study area. Data were collected through farm survey by using a suitable pre-tested questionnaire in February-March, 2016. Profitability analysis, Cobb-Douglas production function, MVP, MFC and Farm Budgeting model were used to analyze the objectives. Average gross return, gross margin and net return were found Tk. 3,47,200, Tk. 1,47,125 and Tk. 1,17,300, respectively. Benefit-cost ratio was found 1.51 and 1.74 on full cost and variable cost basis, respectively. The key production factors, i.e. human labour, land preparation, seed, fertilizer, insecticides and irrigations had significant effect on gross return of potato. Resource use efficiency analysis revealed that farmers were not efficient in using resources in potato cultivation. Human labor, land preparation, insecticide and irrigation were under-utilized and therefore increasing use of those resources could maximize the profitability. Seed and fertilizer constituted major parts of the cost of production hence optimum use of those resources could also enhance the profitability and resource use efficiency of potato cultivation in Munshiganj district.

Potato is an extensively cultivated annual crop in Bangladesh. In some years, when the production of potato is surplus, tons of potatoes are damped due to insufficient storage facilities. This study aims at the use of potato in poultry rations that could greatly benefit the potato farmers and poultry industries. Potato meal was incorporated in rations of broiler (Cobb-500) and fayoumi laying hens, respectively. The rations were isonitrogenous and isocaloric, with the only difference being the content of corn and potato. The results showed there were no differences in feed conversion ratio, survivability rate and dressing percentage among the treatment groups of broiler up to 30% replacement of corn with potato. Furthermore, no notable difference was observed in egg production and egg quality of laying hens on potato diets. These results suggest that potato meal could be included up to 30% as substitute of corn meal in both broiler and laying hen diets without having any negative effects. We believe that the results from this study would significantly contribute to the nation where corn production is not as great as that of potato.

Bangladesh is recognized as a rice-eating nation; nevertheless, large quantities of potato are produced and consumed each year. In Bangladesh, potato has gradually gained popularity. Potato is used as food crop as well as vegetable by both the poor and rich people. Recently, the government has been trying to diversify food habits and encourage potato consumption to reduce pressure on rice. In this regard, potato can play an important role as an alternative and a multipurpose food crop of Bangladesh. This study considered the published secondary data of yearly potato production in Bangladesh over the period 1971 to 2013. The best selected Box-Jenkins ARIMA model for forecasting the potato for whole Bangladesh is ARIMA(0,2,1). The comparison between the original series and forecasted series shows that the fitted model behaved statistically well and suitable to forecast the potato productions in Bangladesh.

The first impact of the potato on society was the intimate relationship between the domestication of the potato and the evolution of Andean civilization which affected Andean culture and religion. In addition to food potatoes were used for several non-food purposes. In the Inca Empire the freeze-dried chuño was collected as taxes from the peasants and disbursed from imperial storehouses to labor gangs for building roads, waging war, and erecting monuments. After the Spanish conquest chuño was used to feed the slaves in the Andean silver and gold mines. This in turn set the stage for flooding the Spanish and eventually the global market with these precious metals and subsequent world-wide inflation of consumer goods. The potato became the major contributor to the European population explosion of 1750–1850 which in turn resulted in increased urbanization and contributed to the underpinning of the Industrial Revolution in England in the nineteenth century. By feeding rapidly growing populations the potato permitted a small number of nations in northern Europe to assert dominion over much of the world between 1750 and 1950. The failure of the potato crop in Ireland in the 1840s led Britain to repeal the protectionist Corn Laws and set the country on a path of free trade. At least one million Irish refugees emigrated, mostly to North America where they left a great legacy. The past 50 years have seen a major global shift in potato production towards many developing countries in Asia, including China and India. Throughout its history the potato has provided bread for the poor. Today it contributes to food security on a global scale. The potato’s depiction on postage stamps demonstrates the esteem in which it is held worldwide and the many references to the potato in art, literature and folklore worldwide are evidence how it has become interwoven in the cultures of many societies today.

About 120 respondents were randomly selected for interviewing and collecting data from Shibganj of Bogra and Kalai of Joypurhat district. The selection characteristics for the respondents were age, education, experience, farm size, family size and annual income. These six characteristics of the farmers were selected for exploring their relationship with their growing preference and production scenario of potato. Age of the potato growers ranged from 27 to 65 years, 20.8% of the farmers was illiterate and most of them have a small family and medium sized farm. About 16.5% farmers have low income up to BDT. 120,000 while 20.8% farmers have an income higher than BDT. 250,000 year-1. Farmers were interested to cultivate the potato due to higher yield and greater profit making than other crops and, they preferred Diamant as the most profitable variety.

A field experiment was conducted in the Western Highlands of Cameroon to study the effects of Calliandra calothyrsus, sterilized compost, non-sterilized compost and mineral fertilizers (NPK 11:11:22) on physical characteristics, yield components and late blight disease severity of potato (Solanum tuberosum). A two factorial treatment combination made up of fertilization schemes and sanitary measures were laid out in a randomized complete block design (RCBD) with four replicates and 10 treatments. Data collected were subjected to a multivariate ANOVA and means separated with the Dunnett t-test with Calliandra calothyrsus considered as the main treatment. Mineral fertilizers and Calliandra calothyrsus significantly augmented stem diameter, plant height and plant vigor, total and marketable yields, despite the fact that late blight severity was high in the two treatments. The correlation matrix showed that total yield had significant and positive correlation with stem diameter (r = 0.74), plant height (r = 0.61), plant vigor (r = 0.61) and marketable yield (r = 0.99) and negative correlation (r = -37) with late blight severity. The increase observed is attributed to the nutrient contents of the treatments applied. Leafy prunings of C. calothyrsus increase soil organic matter which probably improves moisture retention and biological activity. The highest late blight severity recorded between the 45 and 60 coincides with active development of plant canopy which influences disease severity and create a canopy microclimate conducive to disease development. This study suggests that Calliandra calothyrsus has the potential of improving potato production provided appropriate fungicide is used.

This study examines the efficiency of potato farming at the farm level in Bangladesh by estimating technical (TE), allocative (AE), and economic efficiencies (EE) using farm-level cross-sectional survey data from purposively selected six districts: Brahmanbaria, Dinajpur, Joypurhat, Munshigonj, Narsingdi, and Rangpur. This study uses Cobb-Douglas Stochastic Frontier Analysis for measuring TE and after that AE and EE are obtained by applying the Kopp and Diewert stochastic cost decomposition method. Stochastic Frontier Analysis is more applicable to the agriculture sector since it considers an error term that had two components: one to account for random effects (luck, weather, fires, measurement error in the output variable, etc.) which are not under the owner’s control and another to account for technical inefficiency. An evaluation of factors associated with TE, AE, and EE from stochastic frontier analysis reveals that except family size other factors are the significant factors affecting TE, AE, and EE. Findings reveal that there is a considerable amount of technical, allocative, and economic inefficiencies in potato farming and there is potential for boosting output levels through efficiency improvements, hence improving farm revenue and farm household welfare. This study exposes that socioeconomic and infrastructure factors jointly determine the variability of potato output. The importance of education and training in improving farm households' ability to receive and understand information about modern technologies is highlighted in this study. Furthermore, land tenure, as well as management policies, could be designed to reduce land fragmentation in order to better utilization of fertilizer, irrigation, and land preparation using tractors in particular, because fragmentation creates barriers to operating existing technology efficiently and creates difficulties allocating inputs in a cost-effective manner.

The study was carried out using modern inputs against traditional inputs and practices for potato production were conducted in the different agro-ecological zones and agro-climatic locations of Bangladesh during 2011-2012. The selected study areas were brought under potato production with the different modern varieties of potato like Diamant (55%), Cardinal (30%), and Granola (15%). It was observed that the total cost of potato production (fixed cost and variable cost) varied from Tk. 132,180 to Tk. 148,735 ha-1 for modern to traditional cultivation practices. The major cost involvement for modern practices was observed in (a) seed (43.1%), (b) hired and family human labors (19.93%), (c) fertilizer (16.23%), and (d) pesticides (5.26%). And for traditional practices of potato the cost involvement was found (i) seed (46.46%), (ii) fertilizer (21.66%), (iii) hired and family human labors (10%) and (iv) pesticides (9.9%). The cost was comparatively low in modern practices than in traditional practices as it was found mainly due to adoption of recommended technology, appropriate dose and timely use of modern inputs and practices. The yield was found 26 t ha-1 in modern practices and 24 t ha-1 in traditional practices. The net profit was significantly higher in modern practices than traditional practices; the net profit in modern practices was found at Rangpur Tk. 98,079 ha-1 , Thakurgaon Tk. 72,741 ha-1 and Comilla Tk. 46,950 ha-1. It was recommended from the study that the farmers will be economically benefitted if they use modern inputs; adopt technologies; use quality seed of improved varieties at recommended dose; timely use of fertilizers and pesticides; timely application of irrigation; and appropriate crop management including weeding and other practices.

The economic growth of Bangladesh strides forward rapidly since 2000 with the decline in extreme poverty rate to 25% in 2014 from 31% of 2010. Nevertheless,Bangladesh is always on the edge of food insecurity due to number of intertwined factors. Still a large number of people remain unable to access food in the quantity, diversity and regularity re quired for a food secure life. Therefore, this article, by analyzing publicly available data on food security, climate change and Social Safety Nets Programs (SSNPs) of Bangladesh endeavors to critically revisit the underlying challenges and their implications. It finds that the situation of food availability, access and utilization remains challenged considering Bangladesh's unique context and the emergence of issues such as climate change, food prices crises, and food safety and nutrition concerns. Hence, sustainable food security in the fullest essence is highly debatable here. It further terms that SSNPs in Bangladesh as weak since most of them are 'ex-post' coping initiatives only few remains to be 'ex-ante' preventive programs.It also reiterates that failure in'trade-based entitlement', 'labor-basedentitlement' and 'transfer-based entitle-ment' for the landless 11 million rural households is potentially generating food insecurity. Additionally, this paper tries to echo that Article 25 of the Universal Declaration of Human Rights (UDHR) and Article 15 of Bangladesh Constitution obligates Bangladesh to take effective actions for ensuring food security for all. This paper concludes with the call for ensuring effective and efficient SSNPs and nutrition including food safety. The legal regime of food security in Bangladesh would therefore, be well advised to be revisited soon.

Since the latter half of the twentieth century, the rate of increase in potato production in developing countries has outpaced growth rates of most other major food crops. When this book was first published in 1987, the potato was being produced in 132 of the 167 independent countries of the world and more than three billion people, 75 per cent of the world's population at the time, inhabited the 95 developing countries that produced potatoes. As potato cultivation continues to expand at a rapid pace, particularly in the tropics, more attention has been directed towards understanding and improving the nutritional contribution potatoes can make to the human diet. The book reviews the knowledge about the nutritional value of the potato and its role in the nutrition of both children and adults. The synthesis presented in this volume will be of value to students and research workers in nutrition and food science in both developed and developing countries. Dieticians, nutritionists, policy makers and aid personnel involved in agricultural and rural development will also find this book informative and of practical use.
