Abstract: A field experiment was carried out during the kharif season (June–October) of 2016 at the Research Farm of the Indira Gandhi Agricultural University, Raipur (C.G.), India to study the “Effect of site specific nutrient management on uptake of nutrient of rice in vertisolâ€. The experiment was laid out in a Randomized block design with three replications and eight treatments namely i.e. RDF (100:60:40:5 NPK and Zn kg ha-1), SSNM based on nutrient expert (120:60:60:5, NPK & Zn kg ha-1), SSNM based on leaf color chart (60:60:60:5, NPK & Zn kg ha-1, rest 50% N based on LCC), SSNM-N, SSNM-P, SSNM-K, Control (N0, P0, K0) and Farmer Fertilizer Practices (N80, P40, K0).The results was revealed that the highest nutrients uptake- nitrogen 114.3 kg ha-1, Total phosphorus 21.5 kg ha-1 and 185.9 kg ha-1 potassium was recorded under treatment T2 SSNM based (NE) similarly total uptake of Zn were reported 338 g ha-1 under T3-SSNM (LCC) and was also reported that nutrient use efficiency of rice (cv. Rajeshwari) recorded for nitrogen 40.4%, phosphorus 21.2% P, potassium 138 % under treatment T2 based on SSNM (NE).Overall concluded that treatment based on nutrient expert (NE) recommendations proved superiority over applied different treatments on yield, nutrients uptake (N,P,K & Zn) involved balance removal as required by rice as well sustaining soil available nutrient status.
