Present study was established in a randomized complete block design with three replications at Agriculture Extension Demonstration plot Matta Circle Swat Pakistan, in summer 2014. Five levels of phosphorous (20, 40, 60, 80 and 100 kg ha-1) with one control in the form of single super phosphate (SSP) and three cultivars of mungbean (SWAT-I, SWAT-II and NM-54) were used during the experiment. Results revealed that weeds density and phenological traits of mungbean varied with P2O5 application. A linear increase in weeds density was observed with increase in P2O5levels. Fewer days to flowering (40 days) were observed in plots received P at the rate of 80 and 100 kg ha-1 followed by 60, 40, 20 and 0 kg P ha-1, while more (44 days) were recorded in control plots. In case of varieties late flowering (42 days) was observed in variety SWAT I followed by SWAT-II, while early flowering (41 days) was recorded incultivar NM-54. Minimum days (48 days) to pods formation was noticed in P2O5 at the rate of 80 and 100 kg ha-1, while more days (52 days) to pod formation were recorded in control plots. In case of varieties NM-54 took less days (49 days) while SWAT-I were statistically at par. Among the varieties SWAT-I produced maximum biological yield (3551 kg ha-1) followed by SWAT-II (3440 kg ha-1) and NM-54 (3317 kg ha-1) respectively.
