Soil samples were collected before sowing of wheat crop and analysed for physical and chemical properties of the soil. There were six treatments i.e., 0, 30, 60, 90, 120 and 150 kg P2O5 haG1 with three replications. A basal doses of N and K2O at the rate of 140 and 60 kg haG1, respectivelywas also applied. The whole of P, K and 2 of N was applied at the time of sowing and remaining 2 of N was applied at the time of 1st irrigation. The system of layout was Randomized Complete Block Design. The net plot size was 6H4 m. Fertilizer sources of NPK were urea, TSP and SOP, respectively. Wheat variety inqulab-91 was sown as test crop. The data of 1000-grain weight, grain and straw yield was recorded and grain and straw samples were collected and analysed for P concentration. The results showed that 1000-grain weight, grain and straw yields significantly increased with each level of P2O5 application up to 120 kg haG1 and yield at 150 kg P2O5 haG1remained at par with 120 kg P2O5 haG1. Phosphorus concentration in grain and straw and P uptake by wheat also significantly increased in all the treatments except control. Soil analysis after wheat harvest showed a built-up in Olsen-P at higher P levels.]]>Ardell, D.H., L.H. John and A.R. Curtis,20028647Duncan, D.B.,195511142Harbison, D., S. Andrew, P. Flavel, K.
