Abstract: A field experiment was conducted to evaluate the response of wheat crop to phosphorus fertilization in sandy loam soil. 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 P₂O₅haG¹remained at par with 120 kg P₂O₅haG¹. 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.
