Abstract: The pot experiment was conducted at soil science laboratory of C. S. Azad University of Agriculture & Technology, Kanpur with 150kg N+ 75kg P2O5+ 75kg K2O ha-1 in rice crop during kharif 2011 . The other treatments included the 125% increased doses of above and sulphur (60 kg ha-1) and zinc (5 kg ha-1) were added since the experimental soil was deficient in these two nutrients. Mustard was grown after rice on the residual nutrients of the same treatments with application of 80 kg N ha-1 uniformly. The results revealed that rice yields varied from 49.0 to 73.0 q ha-1 and NPK raised by 125% with 60 kg S ha-1 and 5kg Zn ha-1 gave the highest yields. The starch content varied from 65 to 71%, amylose from 27 to 34% and amylopectin from 66 to 73%. The treatment T8 (187.5N + 93.75 P2O5 + 93.75 K2O + 60 S + 20 Zn Kg ha-1) gave the best result in terms of yield and crop quality.
