Abstract: Application of 100% N&K + 75% P through SSP recorded significantly highest N, P, K and S uptake by crop found significantly superior to their lower levels. Results further indicate that solubilization of rock phosphate remained at par with RP:SW@1:80 but recorded significantly N,P,K, and S uptake by grain and straw as compared to remaining levels of rock phosphate and control. The application of RP:SW@1:40 significantly increased the N, P, K and S uptake by grain and straw and total uptake. These improvement manifested in highest values of crop productivity in terms of uptake by grain, straw under this treatment. The RP:SW@1:40 recorded the highest N, P, K and S uptake by wheat crop.
