Nutrient management in pigeonpea [Cajanus cajan (L.) Millisp.] Based intercropping system under rainfed condition of eastern Uttar Pradesh

A field experiment was conducted during kharif season of 2017-18 at Agronomy Research Farm, Narendra Dev University of Agriculture and Technology, Kumarganj, Ayodhya, Uttar Pradesh, India on silty loam soils as influence of integrated nutrient management in pigeonpea based intercropping system. The treatments comprised of three intercropping systems of Pigeonpea sole, Pigeonpea + sesame and Pigeonpea + sorghum with five different integrated nutrient management’s levels. On the basis of results, Pigeonpea with sorghum intercropping systems recorded significantly superior pigeonpea grain yield (16.59 q ha-1), pigeonpea equivalent yield (20.62 q ha-1), gross returns (Rs. 113454 ha-1), net returns (Rs. 84176 ha-1) and B:C ratio (2.87), respectively as compared to Pigeonpea sole and Pigeonpea + sesame intercropping. Among the INM practices, application of 75% RDF + FYM @ 5 t ha-1 + sulphur @ 40 kg ha-1 + ZnSo4 @ 25 kg ha-1 + boron @ 1.5 kg ha-1 prove effective and recorded significantly higher pigeonpea grain yield (16.90 q ha-1) and pigeonpea equivalent yield (20.79 q ha-1), gross returns (Rs. 114363 ha-1), net return (Rs. 84583 ha-1) and B:C ratio (2.84).
