Influence of Phosphorus and Potassium on Yield and Economics of Lentil (Lens culinaris L.)

The field experiment was conducted during Rabi season 2022 at experimental field of Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India to verify the effect of phosphorus and potassium on lentil. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH7.3), low in organic carbon (0.36%), available nitrogen (171.57 kg/ha), available phosphorus (15.40 kg/ha) and available potassium (232.7 kg/ha). The treatments consist of 3 levels of Phosphorus 30, 40, 50 kg/ha and Potassium 15, 20, 25 kg/ha. The experiment was layout in Randomized Block Design with 9 treatments each replicated thrice. Significantly higher yield attributes namely seeds/pod (2.27), pods/plant (91.90), seed yield (1847.93 kg/ha), stover yield (2948.20 kg/ha), maximum gross return (112200.00 INR/ha), net return (81025.00 INR/ha) and B: C ratio (2.59) were obtained highest in (Phosphorus 50 kg/ha + Potassium 25 kg/ha).
