Yield response of wheat to applied p was studied in Pirsabak soil series (Pakistan). Dry matter yield, Plant height and number of tillers per plant showed positive response to adjusted available P at low levels, while negative response was observed for these parameters at higher levels. Phosphorus content of soil and P content of leaf showed corresponding increase to the adjusted available P. The derived non linear equations can be used to calculate the optimum requirement of phosphorus for wheat crop.
