Abstract
A field experiment was conducted during for two years (2015 and 2016) at the Research Farm, FSR center, Main Campus, Chatha of SKUAST–Jammu, during rabi, zayad and kharif seasons on clay loam soil to study the effect of crop bio-intensification and nutrient management on productivity and sustainability of various cropping. The experiment was laid out in Factorial Randomized Block Design with three replications. Under different treatments (crop bio-intensification and nutrient management) the grain yield, straw yield and total bio-mass (q/ha) of maize was found varying. The grain yield, straw yield and total bio-mass of maize was observed more in second year kharif 2015 than first year kharif 2016. Among crop bio-intensification, maize crop sown under Lentil (BB) + Mustard (B) – Summer Moongbean –Maize (BB) + Sorghum (F) practice produced higher grain yield ( 30.16 q/ha and 31.50 q/ha ) than the crop sown under wheat + mustard (6:1) –Summer moongbean – maize (bed) + Cowpea (B) (26.03 q/ha and 26.78 q/ha ) during both of the years of experimentations. The same trend was observed with straw yield and total bio-mass. Among nutrient management, application of 100% in- organic showed higher grain yield, straw yield and total bio-mass than 100% organic (FYM) and INM (50:50) during 1st and 2nd years of experimentations.
