Abstract

Seven combinations of NPK with P applied as P-32 tagged superphosphate were studied for their effect on yield and uptake of phosphorus by four rice varieties viz., CO. 33. CO. 34. CO.35 and Pusa 221. N: POs: KO ratio of 120: 60: 60 (2:1:1) appeared sufficient among the ratios tested for all the varieties studied.
