ABSTRACT
A field experiment was conducted during 2014-2015 and 2015-16 on integrated nutrient management in maize and its residual effect on groundnut under maize-groundnut crop sequence in Southern Telanagana region. The results of the present investigation reflected that the maize plant exhibited maximum values of uptakes of NPK by applying of 75% RDF+25% RDN through urban compost (T5) during both years of study. During the both years of study highest NPK uptakes was obtained by applying 75% RDF+25% RDN through urban compost (T5) followed by 75% RDF+ 25% RDN through FYM (T3) and 100% RDF (T2) of maize crop in maize-groundnut crop sequence. Nitrogen, phosphorus and potassium uptake at initial stage was not significantly influenced by treatments. Post harvest available (N, P and K) content after kharif maize was significantly higher with 50% RDF+50% RDN through urban compost (T6) on par with 50% RDF+50% RDN through FYM (T4). Physicochemical properties of soil were not significantly influenced by different treatments during both the years.
