A field experiment was carried out during kharif season of two consecutive years 2007 and 2008 using same layout on fixed site at Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of Integrated nutrient management in pigeonpea based intercropping system. The treatments were consisted of three intercropping systems (pigeonpea sole, pigeonpea + urdbean and pigeonpea + maize), two seed inoculation levels (PSB inoculation @ 20 g culture per kg seed and no PSB) and three FYM levels (0.0, 2.5 and 5.0 t/ha). The experiment was laid down in factorial randomized block design with 3 replications. Pigeonpea + urdbean intercropping system recorded the highest yield of pigeonpea and pigeonpea equivalent yield (PEY) than sole pigeonpea and pigeonpea + maize intercropping system. Similarly, PSB inoculation and application of FYM at 5.0 t/ha increased the grain yield of pigeonpea, urdbean and maize; and PEY significantly. The highest gross return (` 45587/ha), net return (` 27911/ha) and B: C ratio (1.58) was obtained under pigeonpea + urdbean cropping system. PSB inoculation and 5.0 t FYM/ha also recorded maximum gross return, net return and benefit: cost ratio.
