Effect of nutrient management for sustainable soil health under soybean (Glycine max): Chickpea (Cicer arietinum) cropping system

Abstract

A field experiment was conducted during 2017-18 to 2018-19 at Research Farm, under Indira Gandhi Krishi Vishwavidyalaya, Raipur (CG). With four nutrient management practices to evaluate the effect of residual and direct nutrient application on quality and seed yield of soybean and chickpea on system under Vertisols of Chhattisgarh plains. Results revealed that soil quality parameters such as Dehydrogenase activity, acid phosphates activity and alkaline phosphates activity recorded highest under treatment of 50% recommended doses of NPK and 50% organic on soybean. In chickpea crop, the residual effect of previous crop and direct nutrient application significantly highest yield parameters as well as quality parameters recorded under recommended dose of NPK (25:60:40 kg ha-1) in chickpea which was found at par to the treatment of 50% doses of N and 100% P and K, Under soybean-chickpea cropping system.
