A field experiment was conducted on clay soils of Regional Agricultural Research Station, Lam, Guntur during kharif 2016-17, 2017-18 and 2018-19 to find out the the residual effect of recycling of cotton crop residues on succeeding cotton and impact of recycling of crop residues on yield, yield attributes, soil organic Caron, N, P2O5, K2O and soil microbes invertisols. The three years of the experimental data indicated that the application of RDF @ 150N:60P2O5:60K2Okgha-1 recorded highest plant height (166.5cm), number of bollsplant-1(52.9), seed cotton yield(4568.6kgha-1) followed by 75% RDF + cotton crop residue incorporation + decomposed michorhiza (DM) and was significantly superior over other treatments tried and lowest was recorded with application of cotton crop residue only without any combination of fertilizers and decomposed michorhiza but highest soil microbes population was reported with the cotton crop residue incorporation + 75% RDF + decomposed michorhiza (DM)@2kgha-1 + FYM@ 5tha-1fallowed by cotton crop residue+ 75% RDF + decomposed michorhiza (DM)@2kgha-1under the study. Further, reported that the major nutrient (N, P2O5, K2O) availability status was significantly influenced by the treatments imposed and that the treatment of cotton crop residue incorporation + 75% RDF + decomposed michorhiza (DM)@2kgha-1 was significantly superior on the availability of soil N, P2O5 and K2O respectively in the study.
