Effect of Integrated Nutrient Management Practices on Available Nutrient Status of Soil under Rice-Sorghum Cropping System in Clay Loamy Soils

A field experiment was conducted for two consecutive years 2020-2021 and 2021-2022 on clay loam soil at Agricultural College Farm, Bapatla to study the direct residual effect of integrated use organics inorganics nutrient status under rice-sorghum cropping system. The results revealed that all growth stages rice, highest available nitrogen, phosphorus potassium were recorded with application 100% RDF + 25% N through GLM (T8) this par T9 (100% 12.5% FYM GLM), T3 (125% inorganic fertilizers) T7 FYM, whereas sulphur in it GLM) during 2020 2021. In succeeding sorghum, significantly N, P2O5, K2O T8 FYM) both study. Irrespective treatments applied rice crop, sub plot received (S3) rabi nutrients crop which 75% (S2) except increased NPK levels from RDF(S3) did not show any significant difference lowest control (S1) study, respectively.
