Abstract

Field experiment was conducted at Agriculture Research Farm, Institute of Agricultural Science during 2014-15 and 2015-16. The experiments comprising five levels of phosphorus (control, 100% Recommended dose of N & K +50% P through SSP, 100% Recommended dose of N & K +75% P through SSP, 100% Recommended dose of N & K +50% P through rock phosphate and 100% Recommended dose of N & K +75% P through rock phosphate) in main plots and four levels of solubilization of rock phosphate treatments (control, RP:SW@1:10, RP:SW@1:40 and RP:SW@1:80) in sub-plots combinations of twenty treatment were tested in split plot design with three replications. Wheat HUW-468(variety) was sown seed of 100 kg ha-1 in rows spaced at 22.5 cm. Results revealed indicate that solubilization of rock phosphate remained at par with RP:SW@1:80 but recorded significantly higher plant height (cm), Total number of tillers/m row length, Chlorophyll content (SPAD), Test weight (gram), Grain yield, Straw yield and Biological yield (kg/ha) as compared to remaining levels of rock phosphate and control and Results further indicate that solubilization of rock phosphate remained at par with RP:SW@1:80. Results revealed that application of 100% N&K + 75% P through SSP found significantly superior over the other level.
