Yield and productivity production systems performance of cropping sequences under different

The experiment was carried out at the Research farm of Department of Agronomy, College of Agriculture, CSK HPKV, Palampur during 2019-20 to 2020-21. The experiment consisted with sixteen treatments combinations having four production systems viz, integrated nutrient management, organic farming, natural farming, conservation agriculture in main plots and four cropping sequences viz., maize - wheat , maize + cowpea - wheat + gram, maize + soybean – radish - onion and okra + pole bean - cabbage + garden pea in sub plots. Among the production systems, highest maize equivalent yield (149.70%) was recorded under integrated nutrient management. Among the cropping sequences, okra + pole bean – cabbage + pea had highest maize grain equivalent yield (281.16%) while maize + cowpea - wheat + gram sequence resulted in lowest maize grain equivalent yield. Integrated nutrient management resulted in higher productivity (151.06 % & 150.73%) followed by organic farming and conservation agriculture while natural farming treatment gave lowest productivity. Among the cropping sequences okra + pole bean – cabbage + pea gave significantly highest productivity (396.12 % & 353.04%). Among the production systems, significantly higher value of food availability was recorded under integrated nutrient management and lowest under natural farming and among the cropping sequences significantly higher food availability was obtained in okra + pole bean – cabbage + pea (143.25 & 141.81 %) while maize + cowpea - wheat + gram resulted in lowest food availability.Downloads
