Studies on nutrient management in pigeonpea [Cajanus cajan (L) Millsp] based intercropping system of urd bean, sesame and mung bean

Abstract

A field experiment was conducted during kharif season of 2016-17 at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya Chitrakoot, Satna (M.P.) to evaluate the effect of intercropped urd bean, mung bean and sesame under two level of fertility (100 and 125 % RDF) with pigeonpea regular and paired system. Intercropped pigeonpea numerically reduced seed yield and yield attributes to that of sole cropping. Among interropping pigeonpea+sesame (2:2) produced significantly maximum seed yield (2106 kg/ha). Intercropped urd bean mung bean and sesame produce lower yield attribute than sole cropping of urd bean mung bean and sesame. Among intercropping statistically equal seed yield and yield attribute were recorded in all intercrops. Higher dose of nutrient failed to increase yield attribute and yield of all components crops. Pigeonpea + sesame (2:2) row ratio gave the highest pigeonpea gross returns of 203114/ha, net returns of 185486/ha and benefit: cost ratio of 11.51.
