A field experiment was conducted during the rainy (kharif) seasons of 2013–14 and 2014–15 at Faizabad, Uttar Pradesh, on silty loam soils, to study the effect integrated nutrient management practices on pigeonpea [Cajanus cajan (L.) Millsp.]-based intercropping systems. The treatments comprised 3 intercropping systems of pigeonpea sole, pigeonpea + urdbean [Vigna mungo (L.) Hepper] and pigeonpea + maize (Zea mays L.) with different integrated nutrient management levels. On the basis of 2 year results, pigeonpea + urdbean intercropping system recorded significantly higher pigeonpea seed yield (1.72 t/ha), root nodules, N, P and K uptake by grain and straw/stover over sole pigeonpea and pigeonpea + maize intercropping system. An intercropping of urdbean with pigeonpea recorded significantly higher value of organic carbon, available N, P, K and S contents, net returns (69.5 × 103/ha) over other the other cropping systems at harvest. Among the INM practices, application of recommended dose of fertilizer (RDF) + PSB + Rhizobium + FYM @ 3 t/ha + ‘Harit-vardan’ @ 5 kg/ha recorded significantly higher pigeonpea yield (1.69 t/ha), root nodules, N, P and K uptake by grain and straw/stover, organic carbon, available N, P, K and S contents, net returns (56.8 × 103/ha) over RDF.
