Abstract: A field experiment was conducted on the effect of INM on rice major nutrient content and uptake by rice. It was conducted at College Farm, Agicultural College, Bapatla during the kharif season of two years 2015 and 2016. The treatments consists of M1(100% RDN) and M2 includes 50% RDN+ 25% N through FYM + 25% N through neem cake + recommended dose of microbial consortium (Azospirillum + PSB @ 2.5kg ha-1). Nitrogen content in rice was ranged from 1.71 to 2.22% and 1.58 to 2.18%, phosphorus content was ranged from 0.34 to 0.51% and 0.14 to 0.58% and potassium content was ranged from 1.65 to 2.20% during 2015 and 2016 years respectively (from active tillering to grain filling stage). Nitrogen uptake was ranged from 49.48 to 156.23 kg ha-1, 49.70 to 135.2 kg ha-1, phosphorus uptake ranged from 10.84 to 36.31 kg ha-1 and potassium uptake ranged from 55.03 to 146.94 kg ha-1during 2015 and 2016 years, respectively (from active tillering to grain filling stage).
