The interactive effect of varying levels of phosphorus viz., 100 and 125 kg/ha with that of potassium viz., 50, 75 and 100-kg ha-1 on the growth and yield of hybrid maize "Shahensha" was studies at the agronomic research area, University of Agriculture, Faisalabad during the year 1997. The results revealed that the highest grain yield of 6.02 t/ha and thousand grain weight 405.2 g respectively were obtained from the plot fertilized at the rate of 125-75 PK kg/ha against the lowest grain yield (4.20 t/ha) and 1000 grain weight (372.4 g) were obtained from the control plots. This increase in grain yield was attributed to increase leaf area per plant, greater cob length, increased number of grains per cob and the heavier grain weight.
