Abstract: Pakistan fundamentally requests sustained agricultural development to cope with the social and economic obligations that are the normal consequences of the continued high rates of population growth. An experiment was carried out to check the effect of nitrogen and phosphorus application on weed infestation and wheat productivity at Agronomy Research Farm, the University of Agriculture Peshawar, Khyber Pakhtunkhwa during rabi 2015-2016. The experiment was laid out in Randomized complete block design with factorial arrangement having four replications. The experiment was consisted of two factors i.e. nitrogen levels (80, 120, 160 kg ha-1) and Phosphorus at the rate of (50, 90, 130 kg ha-1) with one control treatment. Results of the study revealed that weeds density were not significantly affected by nitrogen and phosphorus application rates. Weed fresh biomass and dry biomass were found maximum with N and P application at the rate of 160 and 130 kg ha-1, respectively, while grain yield of wheat were found maximum with N and P application at the rate of 120 and 90 kg ha-1, respectively. So, it is suggested that wheat should be cultivated under the application of nitrogen and phosphorus at the rate of 120 kg ha-1 and 90 kg ha-1, respectively in the agro ecological condition of Peshawar.
