Abstract
The field experiment on rice crop was conducted at research farm of C.S.A. University Of Agriculture & Technology Kanpur, during Kharif season 2013. The doses of experiment were 50% NPK , 50% NPK+ S40, 50% NPK + S40 + Zn5, 50% NPK +Zn5, 100% NPK, 100% NPK + S40, 100% NPK + Zn5 and 100% NPK + S40 + Zn5. The results showed that the grain yield varied from 29.5 to 45.50q ha-1 and straw yield from 60.50 to 98.50q ha-1. The N content in grains ranged from 1.42 to 1.50%, P from 0.32 to 0.38 % , K from 1.24 to 1.32%, S from 0.20 to 0.25% and Zn from13.0 to 18.0 mg kg-1. The N content in rice straw ranged from 0.22 to 0.28%, P from 0.17 to 0.24%, K from 0.35 to 0.44%,S from 0.10 to 0.14% and Zn from 27.0 to 40.0 mg kg-1. It was noted the N uptake varied from 55.21 to 105.82 kg ha-1, P from 19.72 to 40.92 kgha-1, K from 85.34 to 150.04 kg ha-1, S from 11.95 to 25.16 kg ha-1 and Zn from 201.65 to 473.15 g ha-1.The starch content varied from 65 to 70%, amylose from 28 to 34% and amylopectin from 66 to 72%. The dose of 100% NPK+S40+Zn5 were found most suitable in respect of crop yield, nutrient content uptake of nutrient and quality of rice.
