— The pot experiment of rice was conducted at pot house of the Department of Soil Science and Agriculture Chemistry, CS Azad University of Agriculture and Technology Kanpur, during the kharif season 2013. The doses of experiment were ½ of soil test recommendation doses, 100% of recommended doses and 75% of recommended doses of N, P2O5 and K2O. The crop was further added with 5 kg/ha Zn and S is 40 kg/ha. The result showed that the grain yield ranged from 26.26 to 53.02 q/ha and straw from 30.90 to 64.30 q/ha. The N content in grain ranged from 1.23 to 1.49%, P from 0.26 to 0.42%, K from 0.29 to 0.51, S from 0.11 to 0.25% and Zn from 14.00 to 25.0 mg/kg. The N content in rice straw varied from 0.49 to 0.59%, P from 0.11 to 0.20%, K from 1.20 to 1.54%, S from 0.103 to 0.183% and Zn from 28.0 to 40.0 mg/kg. It was noted the N uptake 48.13 to 116.92 kg/ha, P uptake from 10.21 to 35.12 kg/ha, K uptake from 44.69 to 119.76 kg/ha, S uptake from 6.06 to 25.01 kg/ha and Zn from 1232.84 to 3897.5 gm/ha. The starch content varied from 63.31 to 73.90%, amylase from 28.00 to 34.00% and amylopectin from 66.20 to 74.50%. The treatment T9 (100% RDF + 25% N Vermin-compost + S + Zn + PSB) gave the best result in term of yields nutrient concentrations uptake value and crop quality.
