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 that available nitrogen in soil at harvest stage found- nitrogen 196.67 kg ha-1, Total phosphorus 16.52 kg ha-1 and 498.33 kg ha-1 potassium was recorded under treatment T2 SSNM based (NE) similarly the available Zinc content in soil at harvest stage of rice was found higher in treatment T3- SSNM on LCC (0.8 mg kg-1). 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(cv. Rajeshwari) as well sustaining soil available nutrient status.
