Abstract
Major proportion of total Phosphorus in Pakistani soils resides in compounds of calcium with varying solubilities. We investigated the differential growth response and P solubilization efficiency of seven wheat genotypes supplied with tri-calciurn phosphate (TCP) and ammonium di-hydrogen phosphate as different P sources, in Johnson's modified solution. The genotypes differed significantly (p < 0.001) in biomass accumulation. Phosphorus concentration and uptake in shoot and P utilization efficiency was also significantly differ for various wheat genotypes. Shoot and root dry matter yield as well as total biomass production correlated significantly (p < 0.01) with their shoot P uptake and P utilization when grown with TCP indicating that genotypes efficient in P solubilization accumulated more biomass
