A screen house experiment was conducted during rabi season of 2018-19 to find out the effect of different levels of P and Zn on wheat yield, concentration of different nutrients in grain and straw in low and high P status soil. Five levels of P (0, 30, 60, 120 and 180 mg P kg-1 soil) and four levels of Zn (0, 2.5, 5 and 10 mg Zn kg-1 soil) were applied in completely randomized design with three replications. The content of all macro and micronutrients were found higher in high P status sandy loam soil of Saniyana as compared to low P status sandy soil of Sadalpur. In low P status soil, the optimum yield of grain and straw was recorded at 30 mg P kg-1 + 10 mg Zn kg-1 level which was found at par with other higher doses of P. While in high P status soil application of Zn alone at 10 mg kg-1 soil was found sufficient to achieve optimum yield of grain and straw. Application of different levels of P and Zn did not significantly influence the N and K concentration in grain and straw of wheat crop in both soils. The higher mean content of P in grain and straw was recorded at 120 and 60 mg P kg-1, respectively and found at par with higher dose of P. In high P status soil, the higher mean P content of grain and straw was recorded at 180 mg kg-1 and 60 mg kg-1 soil, respectively. The maximum mean Zn content in grain and straw was recorded at highest level of applied Zn in both soils. Comparatively higher grain protein content was recorded in high P status soil as compared to low P status soil. However application of P and Zn either alone or in combination had no significant influence on protein content of grain in both low P and high P status soil.
