[more] This paper presents some insight and analysis based on 8-year participatory action research conducted in Udayapur district of Nepal. The study has revealed positive impact of bio-intensive farming system approach in increasing crop diversity and yield efficiency of the farm, improving food/nutritional security and rural livelihoods. Replication of biointensive farming system has been recommended as an effective participatory approach to address the issues of land degradation, ecological degradation, food production, food security and livelihoods dimensions in developing countries like Nepal.

A questionnaire-based survey with 100 household heads along with field visit and personal interaction with the concerned farmers were conducted to gather required information. Data were analysed to compute Rotational intensity (RI), crop diversity index (CDI), land utilisation index (LUI), and yield efficiency (YE). Regression analyses were done to reveal relationships among these traits. BIFS farmers were found to practice scientific crop rotation substantially more than CFS farmers both in rice-based and maize-based cropping systems. In this study, higher RI, CDI, LUI and YE were found in bio-intensive farming system (BIFS) as compaared to conventional farming system (CFS). The study has revealed strong positive relationship of RI with CDI and LUI in BIFS, CFS and in general. Cropping system both in BIFS and CFS with scientific crop rotation that ensures higher CDI and LUI is recommended for increasing yield efficiency. Direct positive relationship among RI, CDI and LUI has been revealed by this study as a rule and has suggested to be used in validating yield efficiency of optonal farming system as compared to the mainstream conventional farming system.

• Yield formation in common buckwheat:III. Effect of Graded Levels of Nitrogen and Phosphorus Nutrition in Indeterminate Ecotype

  Rajbhandari, Binayak P

  Nepalese Journal of Agricultural Sciences. 10/2009; 7:147-152.

  The paper is based on 2-year field-based experimental evaluation of determinate ecotype (D 90151) of Nepali common buckwheat (Fagopyrum esculentum Moench) in Chitwan (345 masl), and Kathmandu (1400 msal). The experimental results revealed that the optimum dose of N:P2O5 for determinate ecotype of Ne... [more] The paper is based on 2-year field-based experimental evaluation of determinate ecotype (D 90151) of Nepali common buckwheat (Fagopyrum esculentum Moench) in Chitwan (345 masl), and Kathmandu (1400 msal). The experimental results revealed that the optimum dose of N:P2O5 for determinate ecotype of Nepali common buckwheat ranges from 20:20 to 20:40 kg/ha with a basal dose of K2O @ 20 kg/ha in Chitwan and Kathmandu. Higher doses of both N and P2O5 and heavy rainfall during flowering and fruit setting caused decline in kernel yield. Application of N:P2O5 @ 20:20 to 20:40 kg/ha with a basal dose of K2O @ 20 kg/ha has been recommended for achieving higher kernel yield of determinate ecotype of Nepali common buckwheat with short plant architecture such as Sathiya in the agro-ecological conditions of Chitwan (terai) and Kathmandu (hill).

[more] A field experiment with common buckwheat laid out on Randomized Complete Block Design with three replications was conducted in Kathmandu during 2000-2002. All treatments: Control pollination (CP); Open pollination (OP) and Bee pollination (BP) plots were maintained in the size of 25 sq m with crop geometry of 25 cm X 5cm. Before anthesis, both the CP and BP plots were caged using crop pollination nylon net with the mesh size of 0.827 mm. One Apis cerana F. colony (strength of five frames) was kept inside the cage near the north-west corner of each BP plot. A supplementary liquid protein diet of 1.5% peptone in 50% sugar syrup was supplied to each colony in a frame feeder once in a week throughout the entire pollination period in late evening to intensify the activities of the bee colony and to prevent bees from malnutrition. The OP plots were grown open to permit the natural pollinating insects visit the flowers; fifty plants were randomly selected in each treatment and replication and their biometric measurements were recorded to determine the effect of bee pollination on the crop yield. The quantitative and qualitative effects of Apis cerana F. on buckwheat yield components showed that, yield decreased with large percentage of wrinkled grains set (5.32+0.39) in the CP treatment. The fertility (2.49+0.18%) and harvest index (10.39+0.52%) were also found low in the CP treatment. BP treatment showed significantly enhanced grain set (33.70+0.56) and the total number of grains per plant (169.76+4.10). Fertility percentage was found higher both in BP and OP treatments as compared to CP treatment. It was observed that fertility percentage increased 5 times and grain yield per plant increased by 3 times in BP as compared to CP treatment. Similarly fertility percentage was 4 times higher and grain yield up to 3 times higher in OP than in the CP treatment. Fertility percentage had statistically significant (P=0.01) positive correlation with total number of grains per terminal inflorescence (r=0.683), total number of grains per plant (r=0.179), and harvest index (r=0.274) in the BP treatment. Key words: Fagopyrum esculentum Moench., Apis cerana F., Fertility, Harvest index, Correlation coefficients.
