Response of Nitrogen and Phosphorus on Growth and Yield of Lentil (Lens culinaris medik.)

The experiment was conducted during Rabi, 2021-22, Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture Technology And Sciences, Prayagraj, Uttar Pradesh, to study the response of nitrogen and phosphorus on growth and yield of lentil (Lens culinaris medik.) The treatments consist of nitrogen 10, 20, 30 kg/ha and phosphorus 30, 40, 50 kg/ha. Theresult reported that treatment 9[Nitrogen 30 kg/ha + Phosphorus 50 kg/ha] gave significantly the higher plant height (38.02 cm), number of nodules (37.44), dry weight (13.80 g/plant). It is also observed that the highest grain yield (1.83 t/ha) and the highest stoveryield (2.66t/ha) was obtained with the application of nitrogen 30 kg/ha along with phosphorus 50 kg/ha. The highest gross return (93211 INR/ha), net returns (63830 INR/ha)and B:C ratio (2.17) were also recorded with application of Nitrogen 30kg/ha + Phosphorus 50kg/ha.
