Effect of nutrient management and cropping system on physico-chemical and nutrient availability of soil in soybean (Glycine max L. Merril)

Abstract

A field experiment was conducted at Research cum instructional Farm, IGKV, Raipur during Kharif 2018 and 2019. The data on bulk density (Mg m-3), pH, EC(dSm-1), organic carbon and availability of N, P and K, the bulk density significantly influenced by nutrient management and cropping system, the highest bulk density in (NM5) 100% RDN through inorganic sources. Whereas the organic carbon in 2018 was remained unaffected and further 2018 it was slightly increases. While the availability of N, P and K in soil was possessed by the treatment supplying in (NM6) 100% RDN through inorganic sources along with FYM @ 5t ha-1. It was found at par with NM1, NM4, and NM5, respectively during 2018.
