Response of frenchbean (Phaseolus vulgaris L.) to various sowing methods, irrigation levels and nutrient substitution in relation to its growth, seed yield and nutrient uptake

A field experiment was carried out in frenchbean (Phaseolus vulgaris L.) during 2010–12 at Agronomy Research Farm, NDUA&T, Kumarganj, Faizabad to study its response to various sowing methods, irrigation levels and nutrient substitution (with organics) under eastern Indo-Gangetic plains of UP. Significantly higher growth attributes in terms of plant height, number of branches and dry matter per plant at harvest, and yield attributes measured through pods/plant and seeds/pod were observed under 15 cm raised bed, irrigation schedule at 1.0 IW/CPE ratio and application of 75% recommended dose of fertilizers (RDF) + 25% N through biocompost as compared to the rest of the treatments. Crop growth analysis viz., LAI, CGR and RGR were significantly superior with the above treatments viz., raised beds, irrigation schedule and 75% RDF + 25% N through bio-compost. As a result, significantly higher seed/straw yield of frenchbean along with higher N, P and K uptake in them were obtained under the above treatments.
