Abstract: Soil phosphorous (P) limitation is one of the most important constraints to food production in Pakistan. An experiment was conducted at Agricultural Research Institute Tarnab, Peshawar during kharif 2016 with an objective to determine best level of P for higher maize yield. Treatments comprised of six P levels (0, 35, 70, 105, 140 and 175 kg ha-1) laid out in randomized complete block design having three replications. Maize hybrid Babar was sown in six rows; 0.70 m apart in a plot size of 4.2 mx 3.9 m. Nitrogen and Potassium was applied at the rate of 200 and 80 kg ha-1 respectively. Crop phenology (days to tasseling, silking and maturity) and yield of maize is significantly affected by mineral phosphorous. Crop phenology was inversely affected by P levels i.e. increasing P from 0 kg ha-1 onwards decreased days to phenology in maize. Phosphorous applied @ of 175 kg ha-1 resulted in highest thousand grains weight, biological yield and grain yield which was statistically not different from 140 kg ha-1 P application. Application of mineral P @ of 140 kg ha-1 gave higher yield under the climatic conditions of Peshawar region.
