Abstract: To study the response of Flax (Linumusitatissimum L.) to phosphorus levels (0, 30, 60, 90 kg ha-1), an experiment was conducted at the Agronomy Research farm, The University of Agriculture, Peshawar during Rabi season 2015-16. Flax cultivar LS 49 was sown in a randomized complete block design (RCBD) having three replications. Phosphorus was applied as soil. DAP was used as a source of phosphorus. Phosphorus has a substantial effect on all yield of flax. Phosphorus application has significantly increased weed fresh biomass (g m-2), weed dry biomass (g m-2) and grain yield of flax. Maximum weed fresh biomass (436.8 g m-2), weed dry biomass (39.8 g m-2) and grain yield (602 kg ha-1) of flax was recorded with P application of 90 kg ha-1, while weed density were not significantly affected by P application rates. The grain yield produce with 60 kg P ha-1 were statistically similar with the yield produce with 90 kg ha-1of P application. So it is suggested that flax should be cultivated under the application of phosphorus at the rate of 60 kg ha-1
