Utilization of cultivable upland of Jharkhand through legume based intercropping system

A field experiment was conducted under All India Coordinated Research Project on (Pulse Research) of Birsa Agricultural University, Ranchi (Jharkhand) to study the suitability of Black gram as intercropped with Pigeon pea (Cajanus cajan) and Maize under varied source of Phosphorus during two consecutive Kharif seasons 2016 and 2017. Pooled data showed that, Pigeon pea + Black gram (1:1) at 50 % RDP+ 40 ppm nano P produced higher system productivity in terms of Black gram yield 1977 kg/ha, Land equivalent ratio 1.64 and benefit: cost ratio 1.83. However, Pigeon pea + Black gram (1:1) grown at 50 % RDP + 40 ppm nano P which were at par at 100 per cent recommended dose of Phosphorus.
