Abstract: The investigation was conducted to determine the effect of different levels of phosphorus fertilizer on growth and yield performance of Lentil (Lens culinaris medic) CV. Masoor-85. Flowering and maturity of the crop was significantly affected by different rates of phosphorus. Maximum 1000-grain weight (19.38 g) was recorded with the application of 75 kg P2O5 ha–1. Application of 75 kg P2O5 resulted in higher yield of 1250 kg ha-1.
