Residual effect of integrated nutrient management in little millet on seed yield, quality and nutrient content uptake by green gram under little millet - green gram cropping sequence

Abstract

A field experiment was conducted to study the residual effect of integrated nutrient management in little millet on production potential of succeeding green gram crop under little millet-green gram cropping system. The residual effect of 50% RDN through chemical fertilizer + 50% RDN through vermicompost to Kharif little millet reported the significant effect on seed yield, quality and nutrient content and uptake of succeeding green gram followed by 50% RDN through chemical fertilizer + 50% RDN through biocompost. Application of 50% RDN through chemical fertilizer + 50% RDN through vermicompost recorded maximum seed yield (991 kg/ha), protein content (19.93 %), protein yield (198.75 kg/ha) and also incresed nutrient content and uptake of seed and stover of green gram. Thus, application of 50% RDN through chemical fertilizer + 50% RDN through vermicompost along with recommended dose of 40 kg P2O5 reported promising effect on seed yield, nutrient content and uptake, quality of green gram in little millet-green gram cropping sequence under South Gujarat condition.
