Reliance on inorganic fertilizers with less or no use of organic fertilizers has impaired the productivity of soil worldwide. An imbalance use of inorganic fertilizers without organic fertilizers has led to deterioration of soil health, crop yield loss which has become a concern. The basic concept of integrated nutrient management (INM) is maintenance or adjustment of soil fertility and supply of plant nutrients to desired crop productivity through optimization of benefits from all possible sources of plant nutrients in an integrated way. This study was executed to quantify the best possible combination of integrated nutrients and their availability to cotton crop. The present study pertains to the effect of Integrated Nutrient Management (INM) on nutrient uptake, post harvest soil available nutrients and NUE of cotton under irrigated condition. The nine treatment combinations comprising of organic manures (FYM, vermicompost), foliar spray (Panchagavya and Dasagavya), inorganic fertilizers (NPK) and bio-fertilizers. T1- Control, T2- FYM @ 10 t ha-1+Bio fertilizer (soil application) +50 % RDF, T3- Vermicompost @ 2.5 t ha-1 + Bio fertilizer + 50% RDF ,T4 - T2+ Panchagavya @ 3% (2 sprayings), T5 - T2+Dasagavya @ 3% (2 sprayings), T6 - T3+ Panchagavya @ 3% (2 sprayings), T7- T3+ Panchagavya @ 3% (2 sprayings), T8- Panchagavay @ 3% (2 sprayings), T9 - Dasagavya @ 3% (2 sprayings). The experimental result showed that the significantly highest nutrient uptake of N, P and K were recorded under T6- Vermicompost @ 2.5 t ha-1+ BF+50% RDF+ Panchagavya spray @ 3% (2 sprayings). The study revealed that, combined application of Vermicompost @ 2.5 t ha-1+Bio fertilizer+50% RDF+ Panchagavya spray @ 3% foliar spray could have impacted on fertility status of soil grown with cotton.
