What are the energy savings associated with reduced tillage and optimized drip irrigation systems and how does the adoption of tillage, trash retention, and fertigation practices contribute to long-term sustainability and climate resilience in sugarcane cultivation?
Relevant answer
Answer
The agricultural sector’s energy use is expected to skyrocket in the future decades. The estimated growth in food demand is outstripping the anticipated increase in energy capacity, which necessitates an increase in energy usage. Energy efficiency refers to the use of less energy to provide the same amount of output and services. Greater energy efficiency in food production systems is required since the projected energy production growth is inadequate and conventional energy sources are limited. Energy is consumed on farms directly as electricity or fuel to power farm activities and indirectly as fertilizers and other agricultural pesticides produced off-farm. Around 18.5 percent of overall energy consumption is spent by agriculture. Processing and transportation of agricultural goods and inputs consume more energy in high-income countries, while cooking consumes the most in low-income countries. The possibilities for increasing energy efficiency in agricultural through the implementation of innovative techniques and practices without compromising agriculture’s high production are needed to be identified for each and every crop and ecology. Conservation agriculture, organic farming, preserving agro-biodiversity, improved soil and water management, integrated pest management, and plant fertilization are some of the strategies and practices that can help the agriculture sector progress toward higher energy use efficiency and sustainability. A higher level of mechanization and advanced food-processing technologies are also important. Rural people are at risk of being left behind unless energy policies are tailored precisely to their requirements.

How does fertigation efficiency influence sucrose content and cane weight in sugarcane production and how does integrating trash retention with fertigation improve root development and nutrient uptake in sugarcane?
Relevant answer
Answer
Fertigation efficiency significantly impacts both sucrose content and cane weight in sugarcane production through precise nutrient and water delivery. When properly managed, fertigation ensures optimal nutrient availability during critical growth stages, particularly during the grand growth phase, leading to enhanced photosynthetic efficiency and improved sucrose accumulation in stalks. The controlled application of nutrients through irrigation water promotes better nutrient use efficiency, resulting in increased cane weight and improved juice quality. Studies have shown that well-timed fertigation can increase sucrose content by 0.5-1.5% and cane weight by 10-15% compared to conventional fertilization methods.
The integration of trash retention with fertigation creates a synergistic effect on root development and nutrient uptake in sugarcane cultivation. The retained trash layer acts as a natural mulch, maintaining soil moisture and reducing temperature fluctuations, which creates an ideal environment for root proliferation. This organic layer gradually decomposes, releasing nutrients slowly while improving soil structure and microbial activity. When combined with fertigation, the trash blanket enhances nutrient retention in the root zone, reduces leaching losses, and promotes the development of fine root hairs crucial for nutrient absorption. The improved soil biological activity under trash retention also enhances nutrient cycling and organic matter decomposition, leading to better nutrient availability and uptake efficiency. Research indicates that this integrated approach can improve root biomass by 20-30% and increase nutrient use efficiency by 15-25% compared to conventional practices.

How do fertigation practices influence carbon footprint and greenhouse gas emissions in sugarcane farming?
Relevant answer
Answer
Fertigation alone does not enhance the scope of carbon footprint and emissions as has been very well brought out above. Carbon footprint and carbon emissions are indeed misplaced since we have not understood climate change properly (you may please read my articles on this platform - How well do we know climate change? and a few related contributions. Climate change deserves a better understanding before we emphasise on carbon emissions and carbon footprint. May I suggest you browse through the available literature before embarking on an appropriate approach on the topic.

How do different tillage practices impact on sugarcane biomass accumulation and yield under drip irrigation and what is the effect of trash retention on nutrient availability, soil health and overall crop productivity?
Relevant answer
Best tillage practices for maximizing sugarcane biomass accumulation and yield under drip irrigation are minimum or strip tillage, which provide a balance between aeration, moisture conservation, and root health. Zero tillage is also highly effective in maintaining long-term soil fertility and water retention, especially in well-structured soils. Deep tillage should be used selectively for compacted soils, while raised bed planting is ideal for waterlogged conditions. By adopting conservation tillage practices that optimize soil health and moisture retention, farmers can significantly enhance sugarcane productivity under drip irrigation.
  • asked a question related to Sugarcane
Question
1 answer
How does tillage intensity impact water-use efficiency and irrigation requirements in drip-irrigated sugarcane and what role does trash retention play in reducing irrigation demand and improving soil moisture retention?
Relevant answer
Answer
The intensity of soil tillage significantly affects water use efficiency and irrigation needs in drip-irrigated sugarcane. The way the soil is prepared and maintained directly influences water infiltration, evaporation, and moisture retention.
Impact of Tillage Intensity on Water Use Efficiency and Irrigation Needs:
  1. Intensive Tillage (Deep and Frequent Tillage)Increased Evaporation – Deep tillage can disrupt soil structure, leading to higher moisture loss through evaporation. Reduced Organic Matter – Accelerated decomposition of organic matter decreases the soil's ability to retain moisture. Higher Irrigation Demand – Faster moisture loss necessitates more frequent irrigation, reducing overall water use efficiency.
  2. Minimal or Conservation TillageImproved Infiltration and Water Retention – Maintaining soil structure allows for better water retention in the root zone. Lower Irrigation Requirements – Less disturbed soil holds moisture better, reducing the frequency of irrigation. Preservation of Organic Matter – Organic matter enhances the soil’s capacity to store water.
Role of Trash Retention in Reducing Irrigation Demand and Enhancing Soil Moisture Retention:
  1. Reduced Evaporation – A cover of crop residues acts as a barrier, limiting direct exposure of the soil to sunlight and wind, thus minimizing water loss through evaporation.
  2. Improved Infiltration – A layer of organic material slows water runoff, allowing better penetration into deeper soil layers.
  3. Soil Structure Preservation – Reduces erosion and soil compaction, enabling sugarcane roots to access water more effectively.
  4. Microbial Activity – The decomposition of organic material enhances the humus layer, increasing the soil's water-holding capacity.
Minimal tillage and trash retention are effective strategies for reducing irrigation demand in drip-irrigated sugarcane. These practices improve soil moisture retention, decrease evaporation, and enhance water infiltration, leading to more efficient use of available water resources and a reduction in overall irrigation needs.

Has anyone experienced difficulties during laccase assay measurements?
I have an enzymatic extract from a solid-state fermentation of sugarcane bagasse. The extract is dark, which interferes with the use of ABTS as a substrate for measuring laccase activity.
The ABTS is taking an unusually long time to be oxidized (more than 24 hours). I have already tried dialysis, but it still hasn't turned green or blue.
Does anyone have any recommendations?
Relevant answer
Answer
11/14/24
Dear Clara,
Is it possible for you to concentrate the enzyme by precipitating if from the extract? If there is enough protein in the extract, you may be able to precipitate the enzyme (as well as other proteins) using ammonium sulfate ((NH4)2SO4). Ammonium sulfate (AS) at ~65-70% is an effective concentration for precipitating proteins. It is an old technique, but it does work. The AS competes w/ proteins (and other solutes) for the available water, causing proteins to precipitate. This can be recovered by centrifugation. Much of the unwanted material (hopefully the dark material in your extract) will remain in solution. If this works, you can recover the protein precipitate and dissolve it in an appropriate buffer, then assay it for activity.
I hope this information helps you.

Question

I have an inquiry regarding nitrogen nutrition in sugarcane, and I trust that experts in nutrition and sugarcane research may provide insights.
Many sources indicate a positive correlation between the moisture content of sugarcane sheaths and the percentage of nitrogen in the leaves. However, I have not observed any significant positive or negative impact of foliar nitrogen on pod moisture levels.
In one of my experimental designs concerning sugarcane nutrition, I recorded multiple measurements, and the treatment with elevated leaf nitrogen concentration exhibited increased pod moisture.
If my findings are accurate, what supporting evidence do you possess regarding this matter?
Furthermore, can the beneficial influence of nitrogen on root development and enhanced water absorption be considered a valid rationale?
It is important to note that all environmental conditions, soil types, and irrigation methods were consistent across both treatments, with the sole variable being the quantity of nitrogen fertilizer applied.
Relevant answer
Answer
Your observation that higher nitrogen levels in sugarcane resulted in increased pod moisture, despite no direct correlation with leaf nitrogen content, can be explained by several factors:
  1. Root Development and Water Uptake: Nitrogen stimulates root growth, enhancing the plant's ability to absorb more water. This increased water uptake could lead to higher moisture content in the pods.
  2. Water Retention: Nitrogen may promote biochemical pathways that regulate water retention in the pods, especially under optimal soil moisture conditions.
  3. Supporting Evidence: Research supports the idea that nitrogen improves root development and water use efficiency, which could explain the increased moisture content in your experiment. Studies indicate that enhanced nitrogen nutrition can lead to better water absorption, thereby affecting moisture levels in different plant organs, including the pods.
In conclusion, your findings are consistent with established knowledge on nitrogen's role in improving root development and water absorption, which could plausibly explain the increased pod moisture you observed.

For concrete mix design, which is the correct method in calculating the weight of the supplementary material for (1:2:4) mix ratio at 5% replacement with SCBA? Given the specific gravity of cement =3.1, sand = 2.6, gravel = 2.75, sugarcane bagasse = 2.8
a) Total volume = 1m3, Volume of cement = 1/7 = 0.143, Mass of cement = 3.1*0.143*1000 = 443. Weight of 5% SCBA = 0.05*443 = 22.15kg
b) Total volume = 1m3, Volume of cement = 1/7 = 0.143, Mass of cement = 3.1*0.143*1000 = 443. Weight of 5% SCBA = 0.05*0.143*2.8*1000 = 20.02kg
Relevant answer
Answer
Method A:
- Total volume: 1m³
- Volume of cement: 1/7 = 0.143
- Mass of cement: \( 3.1 \times 0.143 \times 1000 \) = 443 kg
- Weight of 5% SCBA: \( 0.05 \times 443 \) = 22.15 kg
Method B:
- Total volume: 1m³
- Volume of cement: 1/7 = 0.143
- Mass of cement: \( 3.1 \times 0.143 \times 1000 \) = 443 kg
- Weight of 5% SCBA: \( 0.05 \times 0.143 \times 2.8 \times 1000 \) = 20.02 kg
Correct Method:
Method A is correct because it straightforwardly calculates the 5% replacement of cement by weight. Here’s why:
- The 5% replacement is directly related to the weight of the cement, not to the volume.
- \( 5\% \) of the 443 kg of cement is indeed 22.15 kg.
In Method B, multiplying by the specific gravity of SCBA (2.8) along with the volume doesn’t align with the standard practice of calculating the replacement material by its weight proportion.
So, Method A: is the accurate approach to determine the weight of SCBA for a 5% replacement of cement in a (1:2:4) mix ratio.

Fertigation has becoming a common technology adopted by the farmers under protectively cultivated and protectively irrigated situations. Many companies dealing with plant nutrients are prescribing huge quantum of nutrients specially for crops like tomato, sugarcane etc. Is there a technological rationale / approach behind this heavy nutrition?
Relevant answer
Answer
The adoption of fertigation, especially in protected cultivation and irrigated agriculture, has indeed become increasingly popular due to its efficiency in delivering nutrients directly to plants through irrigation systems. However, the practice of prescribing large quantities of nutrients, particularly for crops like tomato and sugarcane, requires careful consideration and justification. Here are some technological rationales and approaches that may explain the use of heavy nutrition in fertigation:
1. High Yield Expectations: Crops like tomato and sugarcane are often high-yielding and have intensive nutrient demands to support vigorous growth and productivity. Fertigation allows precise control over nutrient application, enabling farmers to supply nutrients in quantities that match the crop's high yield potential.
2. Nutrient Mobility and Uptake: Certain nutrients, such as nitrogen, potassium, and phosphorus, are highly mobile in the soil and easily leach away with excess irrigation water. Fertigation helps to minimize nutrient losses by delivering nutrients directly to the root zone, enhancing their availability for plant uptake.
3. Crop Growth Stages and Nutrient Demand: Different crops have varying nutrient requirements at different growth stages. Fertigation allows farmers to tailor nutrient applications according to the crop's growth stage, ensuring that nutrient availability matches the plant's demand throughout its development cycle.
4. Precision Agriculture: Fertigation enables precision agriculture practices, where nutrients can be applied in precise quantities and at specific times based on real-time data, soil analysis, and crop monitoring. This approach maximizes nutrient use efficiency and minimizes waste, leading to optimal crop nutrition and performance.
5. Soil and Environmental Conditions: Soil fertility, texture, pH, and environmental conditions can influence nutrient availability and plant uptake. Fertigation allows for adjustments in nutrient formulations and application rates to compensate for variations in soil and environmental factors, ensuring that plants receive adequate nutrition under diverse growing conditions.
6. Crop Varieties and Genetics: Modern crop varieties, especially hybrids and genetically improved cultivars, often have higher nutrient requirements to support their genetic potential for yield and quality. Fertigation allows for precise nutrient management to meet the specific needs of different crop varieties and optimize their performance.
While there may be technological justifications for prescribing heavy nutrition in fertigation, it is essential for farmers and agronomists to carefully consider factors such as crop nutrient requirements, soil fertility status, environmental sustainability, and economic viability. Over-application of nutrients can lead to nutrient imbalances, environmental pollution, and economic losses. Therefore, nutrient management strategies should be based on sound agronomic principles, supported by soil testing, crop monitoring, and integrated nutrient management practices to ensure optimal crop nutrition and sustainable agricultural production.

is it good to use mixture of sugarcane bagasse and molasses for mixotrphic cultivation of microalgae
Relevant answer
Answer
Yes, using a mixture of sugarcane bagasse and molasses for mixotrophic cultivation of microalgae can be beneficial.
Sugarcane bagasse is a low-value agricultural by-product that is currently underutilized12. It can be used as an organic carbon source for the mixotrophic cultivation of microalgae12. For instance, a study on Scenedesmus dimorphus NT8c showed that cultures raised mixotrophically in 5 g/L sugarcane bagasse hydrolysate displayed significantly higher growth rates compared to photoautotrophic cultivation12.
Molasses, a by-product of the sugar industry, is rich in sugars and can be used as a carbon source for microalgae growth34. The sugars in molasses can be metabolized by the microalgae, providing energy for growth34.
However, it’s important to note that high supplementation with organic carbon can result in unfavorable levels of turbidity and bacterial growth, reducing microalgal biomass productivity12. Therefore, the concentration of sugarcane bagasse and molasses should be optimized for the specific strain of microalgae being cultivated.
Remember, the success of mixotrophic cultivation can depend on various factors including the strain of microalgae, the quality and concentration of the organic carbon sources, and the cultivation conditions.

How can be use Sugarcane bagasse and filter mud to improve biomethane production?
Relevant answer
Answer
Sugarcane bagasse and filter mud are byproducts of the sugar production process and can be effectively used to improve biomethane production through anaerobic digestion. Anaerobic digestion is a biological process where microorganisms break down organic materials in the absence of oxygen, producing biogas (which contains methane) as a byproduct. Here's how you can use sugarcane bagasse and filter mud to enhance biomethane production:
Collect and Prepare Feedstock:
· Sugarcane Bagasse: Sugarcane bagasse is the fibrous residue left after sugarcane is crushed to extract its juice. Collect and prepare the bagasse by shredding or chopping it into smaller pieces to increase its surface area, which will aid in the digestion process.
· Filter Mud: Filter mud, also known as filter cake, is the solid residue obtained during the sugar refining process. It can be used as a co-substrate with sugarcane bagasse for anaerobic digestion.
Mixing and Pretreatment:
· Mix the sugarcane bagasse and filter mud in appropriate proportions to achieve a balanced carbon-to-nitrogen (C/N) ratio. A C/N ratio of around 20-30 is typically suitable for anaerobic digestion.
· Optionally, you may need to pretreat the feedstock to break down lignocellulosic materials in the bagasse, which can be resistant to microbial digestion. Common pretreatment methods include steam explosion, acid hydrolysis, or enzymatic treatment.
Anaerobic Digestion:
· Place the mixed and prepared feedstock into an anaerobic digester, which can be a sealed tank or a lagoon.
· Inoculate the digester with a suitable consortium of anaerobic microorganisms, often obtained from a well-established digester or a commercial inoculum.
· Maintain the operating conditions, including temperature (typically around 35-55°C), pH level (around 6.5-7.5), and retention time (the time material stays in the digester), to optimize methane production.
Monitoring and Optimization:
· Regularly monitor the digester's performance by measuring parameters such as biogas production rate, methane content in the biogas, pH, and temperature.
· Adjust the feedstock mix, temperature, and other factors as needed to optimize the digestion process and maximize biomethane production.
Biogas Collection and Utilization:
· Collect the biogas produced in the digester and separate methane from carbon dioxide and other impurities.
· The purified methane (biomethane) can be used as a renewable energy source for various applications, including electricity generation, heat production, or as a vehicle fuel.
Residue Management:
· The digestate, which is the solid residue remaining after digestion, can be used as a nutrient-rich organic fertilizer. It contains valuable nutrients and can improve soil health.
· By effectively using sugarcane bagasse and filter mud as feedstock for anaerobic digestion, you can enhance biomethane production while also managing and reducing waste from the sugar production process. It's essential to continuously monitor and optimize the digestion process to maximize methane production efficiency.

2. What data (# disease clumps or disease incidence) is appropriate to use for analysis? Further, it would be a great support if anyone can give an idea of how to write CLASS and MODEL statements of SAS for analyzing this data.
Thank you
Relevant answer
Answer
You can analyze either number of infected clumps or disease incidence (that I understand as number of infected clumps / number of total clumps). The first is count data that follow Poisson or Negative Binomial distribution whereas the second is a proportion that follow a binomial distribution. Therefore, classical methods like Analysis of Variance (ANOVA), a specific case of general linear model, are not appropriate even with prior data transformation like root square or arcsinus (O'Hara and Kotz, 2010; Wharton and Hui, 2011).
Ignoring the repeated measurement, considering data for each month separately, it is highly advisable to use Generalized Linear Model (GLM) with appropriate distributions and link functions that lead to Poisson regression for number of infected clumps and logistic regression for disease incidence. For Poisson regression, overdispersion should be checked and if it is present, use Negative Binomial regression instead of Poisson regression.
To take into consideration repetition in time, the likely correlation between time points (months) should be considered by using Generalized Estimating Equations (GEE) or Generalized Linear Mixed Models (GLMM) (Gbur et al, 2012; Stroup, 2013; Yirga et al, 2020).
In SAS, GLM is done using PROC GENMOD while GLMM is done using PROC GLIMMIX.

Diaz, P.. (2016). Consequences of Compost Press Mud as Fertilizers. DJ International Journal of Advances in Microbiology & Microbiological Research. 1. 28-32. 10.18831/djmicro.org/2016011005. Organic fertilizers derived from Sugar Press Mud (SPM) yields better production of crops. Sugar press mud or the sugarcane filter-cake is the residue of sugarcane industry which results from the processing of sugarcane where sugar mud is separated from the crush. The total supply of sugar press mud varies from (1-7) kg from the processing of 100 kg of sugarcane. Sugar filter cake is used as a suitable fertilising agent since it is rich in micro and macro nutrients along with organic carbon. It is eco-friendly and protects the plants from various soil borne diseases. Press mud compost does not include any substances which are unfavourable for microbial action. In certain cases, press mud is mixed with other organic fertilizers to yield enriched compost. Whatever the case, the resultant press mud should not be added to the soil directly as it affects the welfare of human health due to the fast growth rate of pathogenic fungi. These are the disease causing microbes whose growth rate must be inhibited. The review deals with the physical, chemical and microbial functions on the press mud resulting in excellent bio-fertilizers. Enriched press mud is mixed with gibberellic acid to inhibit the growth of toxic chromium which affects the metabolism of plants. The fields which are ineffective by the over use of chemical pesticides can be brought into control by constant use of bio-fertilizers such as press mud. Usage of chemical pesticides may destroy the insects causing damage to the fields, but its impact over the health of living beings is tremendous. Press mud, on the other hand, is safe and very effective in producing income and killing certain insects affecting the crops as well.

Good practices during preparation, fermentation and distillation can reduce the concentration of acetic acid in distilled spirit to keep the standard quality of final product. However, I want to ask if is there any corrective measures to reduce the high acidity found in the product after processing?
Relevant answer
Answer
The citric acid is used as a preservative, in the process is the main reason of acidity. Acidity content was determined as citric acid according to Adekunte AO et al. Sugarcane juice is acidic in nature (pH 5.28–5.54 and acidity 0.24–0.39%).The acidity is directly proportional to pH. during storage of sugarcane juice. Addition of organic acids to juice also increased its acidity and decreased pH. The pH value: The pH value of sugarcane syrup in the control samples of all treatments was the highest, ranged from 6.16 for 70H1 to 6.68 for traditional treatment while commercial samples 6.16. However, sugarcane syrup pH value decreased with the addition of citric acid to pre-treatment sugar cane juice used to produce syrup in all treatments ranged from 4.16 to 5.08. The superior level of pH establish according to pH (4.5 to 5.5) of the sugar cane juice.Addition of potassium metabisulphite to juice restricted the microbial activity during stroage resulting in significantly (P<0.01) less reduction in pH and less increase in acidity. The reduction in pH and increase in acidity, however, higher when the juice samples store at room temperature. No significant change in viscosity as a result of addition of organic acids or potassium metabisulphite and storage at room or refrigeration temperature. The citric acid able to lower the pH of sugarcane juice to 4.9 which gave a preservative action and inhibit the growth of micro-organism during storage. Potassium metabisulphite is also a known yeast and mold inhibitor and is being used widely for the preservation of foods.

Relevant answer
Answer
Look →" Biology, agricultural impact, and management of Cyperus rotundus L.: the world’s most tenacious weed"
Abstract
Purple nutsedge (Cyperus rotundus L.), a troublesome weed, is economically damaging weed, which is widely naturalized in the tropical and subtropical regions of the world. This weed has been reported to cause 20–90% yield losses in various agronomic and horticultural crops across the world. Perennial nature, genetic diversity, ability to tolerate adverse climatic conditions, high rate of reproduction, ease-of-dispersion, strong competitive abilities, and allelopathic potential assist this weed to thrive in a range of agro-climatic regions. Routine cultural approaches, including crop rotation, crop choice, and mechanical cultivation, are ineffective in achieving season-long management of C. rotundus. Pre-emergent and post-emergent herbicides, as well as myco-herbicides, can control its growth but fail to limit the regenerative capacity and tuber viability of C. rotundus in the long term. Integration of herbicides with tillage operations during summer fallows would be a reliable option to desiccate the tubers and rhizomes of C. rotundus. Furthermore, preventive measures as well as complete destruction of nascent foci would be helpful in preventing future spread of this weed. This review will help researchers and scientists in understanding the reproductive biology and future threats of C. rotundus, leading towards the development of improved control methodologies. The information presented in this article will also enable researchers and growers to address the prevailing gaps in the eco-biology of this weed for the long-term control of C. rotundus in economically important field crops.

Answer
Hello Adrien,
The gold standard method, of course, to determining causal influence for a variable or variable set is to manipulate that variable (or set) on randomly assigned cases and collect results on the subsequent values of the outcome variable(s) of interest.
If that's not feasible, then what you can do is evaluate how much (if any) explanatory power the individual variable/s may have, being sure to include interaction terms among the variable set under consideration. Of course, there is always the possibility that you are omitting one or more important variables from the set being evaluated (or that there is something idiosyncratic about the responses observed from the data you did collect, which might not generalize, or could again represent an unmeasured influence). Multiple linear regression would be a plausible framework for initiating this type of analysis.
Good luck with your work.

Sugarcane is a member of the grass family and is valued chiefly for the juices that can be extracted from its stems. The raw sugar that is produced from these juices is later refined into white granular sugar. As a sugarcane plant matures throughout the growing season, the amount of total sucrose in the cane increases. Most of this sucrose production occurs when the plant has fully matured and begins to ripen.
Relevant answer
Answer
The following are used to determine sugarcane quality factors : 1- Sampling of stems of sugarcane and syrup extraction. 2. Pour about 100 cc of the desired syrup into Erlen and add 2 g of Pb-acetate to the mixture, then remove the samples from the filter paper and smooth. 3. After smoothing, pour about 15 cc of the filtered liquid into the saccharimeter and read the number called pol-Read (Sucrose syrup percentage). 4- Drop a few drops of the main syrup (without adding Pb-acetate) onto the punch of the brixometer or refractometer and read Cor.Brix, which is the same amount of solids in the sugarcane extract, including all sugars, salts and all substances soluble and insoluble relative to the volume of the syrup. 5. Correct pol-Read readings according to relevant tables and determine pol percentage. 6. Determination of Purity Factor (Pty) or percentage of syrup purity by dividing %Pol into Brix. 7. Using the relevant tables and the Purity correction factor, we obtain the percentage of Pty and divide it into% Pol to obtain the QR. Divide the number 100 by QR to obtain YieldYield (yellow sugar). 9. Multiply the Yeild number (yellow sugar) by the coefficient of 0.83 to obtain the percentage of white sugar (% RS) and the factor SY (refined white sugar end product) is obtained by multiplying the sugar tonnage by Rs.

Question

Sugar beet has the advantage of low crop water demand over sugar cane. It may save huge amount of irrigation water when compared to sugarcane. Moreover, crop duration of sugar beet is 5-6 months which is nearly half of sugar cane growing period. It is possible to cultivate two crops in a year. The sugar content of sugar beet is also considerably good. The above ground portion of the plant can be used as fodder as well. My question is, whether sugar beet can be an alternative / substitute for sugarcane in the future without affecting sugar production of the country? What are all the major constraints in promoting sugar beet? Please give your answer with justification. Many thanks in advance.

Answer
Just citing:
" The key advantages of sugar beet in comparison with sugarcane are well-known: a shorter growing cycle (around 5 months), lower water requirement (about 1/ 3rd to half of the water needed to grow sugar cane) and a slightly higher sugar (16-19% sucrose) and ethanol yield per acre (1000 to 1200 liters/ha). In addition, sugar beet is well known tolerant crop to soil salinity (Steven Cosyn et al., 2011). More over due to short growing season in comparision to sugar cane the sugar beet provides an opportunity of crop rotation to farmers, and is probably one of the efficient ways to maintain soil fertility and to control pests and disease. Finally, by processing sugar beet after or before the regular sugar cane crushing period, factories can stretch their operations over a longer period." (Anand SR, Vishwanatha J, Karegoudar AV, Rajkumar RH, Ambast SK. Effects of dates of sowing and planting geometry on yield and quality of sugar beet under saline Vertisol of Tungabhadra Project (TBP) area of Karnataka. Journal of Soil Salinity and Water Quality. 2013;5(1):56-9. )
" Significant efforts have been recently done to introduce sugar beet in regions where it has now a limited presence as a commercial crop. In field trials in India during 2007-2009 at ten sites beet yields of between 681 and 106 t/ha was achieved with sucrose content of 20% on average. However, perhaps the key obstacle to the rapid introduction to beet production and beet sugar processing in cane factories in tropics is the rather heavy capital investment to upgrade factories to allow them to process sugar beet. But the need to increase the sugar and ethanol production level for many developing countries, the need to diversify the crop portfolio to reduce production costs and to secure the supply in factories, as well as the extraordinary yield potential of sugar beet has increased the interest for the use of sugar beet in new markets"

Foliar fertilization is a quick and efficient way to improve crop nutrient status during periods of high nutrient demand in the crop, or soil-applied fertilizers less available to the plant.
My questions what is an appropriate time to supply nutrients as foliar for sugarcane crop. The nutrient contains nitrogen, phosphorus, potassium, Sulfur, Calcium, Magnesium, zinc, iron, manganese, and copper when we added as a single or combined system.
. it is critical to determine the effect of crop load on the capacity of properly timed foliar fertilizers to increase the yield of sugarcane.
The question for researchers in the fields of soil science, plant nutrition, crop physiology and agronomist specialized in sugarcane crop.
Therefore, my request is to provide me with any practical suggestions to increase my knowledge concerning these issues, besides the literature review, technical report and articles also are needed.
Relevant answer
Answer
The best timing is when the plant has the biggest foliage unless there is a need to spray earlier than that (i.e. to cure nutrient deficiency)

I am doing a study on the life cycle of sugarcane bioethanol. I am starting with sugarcane farming and will proceed to sugar and molasses production and finally ethanol production from molasses. I will eventually also need data of waste generation from both the sugar plants and the bioethanol plants from various countries.
If anyone has such data kindly share with me please.
Thanks

I want to estimate nitrogen (N) content in the sugarcane fields using sentinel-2 optical data (Multi spectral Imagery). I have read few papers where simulated values helped in potatoes and other field but not for sugarcane.
If possible, I am ready to see for other remote sensing techniques to estimate nitrogen.

I want to let the pipe with sugarcane water with jaggery boiler when the jaggery is crystallizing the pipe also filled with crystal. Since, pipe to touch top of jaggery in boiler. Since the sugar water flow will spread drop in boiler every where. So the solvent used to dissolve the jaggery in pipe. Else the crystal can’t allow the sugar water to flow. If crystal more in pipe then the pipe has to be changed. These setup is fixed how I can safe the pipe crystal inside.

I seek the experts suggestions / guidance to apply the fertilizer doses according to the medium range (3-10 days) weather (Rainfall, maximum temperature, minimum temperature, morning and afternoon relative humidity, cloud cover, wind speed and wind direction) forecast especially for cotton and sugarcane crops, under Indian Punjab conditions. The description of the detailed methodology are highly welcomed.

Good Evening Sir, Sudhir Kumar Mishra
I think, for fertilizer application, we usually follow the doses as recommended by the University, which can further be altered based soil-testing of that particular site.
Medium range weather Forecast, aids in manipulation of the management activities at field level like
We should withheld/delay fertilizer application if the forecast tell about the chances of rain in that particular area to prevent its loss due to runoff, leaching, volatilization, reduction due to ponding of water etc etc.
Apart from that we should think about, how variables other than rainfall (i.e the period in which rainfall is absent/not predicted) viz. Max and Min temperature, Relative Humidity, cloud cover, wind speed and direction as generated in the Quantitative product of these 7 weather parameters by IMD, can affect the dynamics of Fertilizers in the field.
i.e how crop and soil respond to the available/applied fertilizer in the field, by making several combination of these variables.
