Abstract
A study was undertaken to investigate the utilization efficiency of phosphorus in wheat variety "Blue Silver" at the Agronomic Research Area, Faculty of Agriculture, Gomal University, D. I. Khan during the year 1980-81. Phosphorus at the rate of 50 pounds per acre was applied in both full and split doses. The full dose was applied at three stages i.e. sowing, tillering and booting and the split was applied half at sowing and half at tillering and 1/3 at sowing, 1/3 at tillering and 1/3 at booting stage. The results indicated that application of 50 pounds phosphorus at sowing time helped improve the germination counts per unit area and had non significant effect on plant growth. Split application of phosphorus at different stages of plant development significantly increased number of tillers, grain weight and grain yield, but straw yield was not affected significantly. Harvesting index and phosphorus utilization efficiency were also increased with split application of phosphorus.
