Response of land configurations, IW/CPE ratios and integrated nutrient supply systems on growth function, yield and water use efficiency of French bean (Phaseolus vulgaris L. PDR-14)

摘要

Field experiments were conducted during two consecutive years of 2010-11 and 2011-12 at Agronomy Research Farm of NDUA&T, Faizabad (UP.) India to study the response of land configurations, IW/ CPE ratios and integrated supply systems on growth function, yield and nutrient study of french bean (Phaseolus vulgaris L.) under indo-gangetic eastern plains zone of Uttar Pradesh. Significant increase was observed for plant height, number of branches and dry matter accumulation per plant at 60 and 90 days after sowing and at harvest under 1.0 IW/CPE moisture regime nourished with 75% RDF through chemical fertilizers + 25% N through biocompost at raised bed configuration. Higher growth attributes resulted maximum yield and yield attributes of French bean with sowing at raised beds, application of 75% RDF+25% N through biocompost and IW/CPE ratio of 1.0 as compared to rest of the treatments. Increasing moisture regimes decreased the water use efficiency and it was highest under sowing on raised beds, moisture regime at 0.6 IW/CPE ratio and 75 % RDF through chemical fertilizers + 25 % N through biocompost nutrient supply system. Higher yields of French bean was obtained with treatment combinations of sowing on raised beds, moisture regime at 1.0 IW/CPE ratioand 75 % RDF through chemical fertilizers + 25 % N through biocompost and it was most remunerative and sustainable under Indo-gangetic plains of UP.
