Phosphorus and Sulphur's Impact on Lentil Growth and Yield (Lens culinaris Medik.)

During the Rabi season of 2022–2023, a field experiment was carried out at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) India. to research how the nutrients phosphorus and sulphur affect the productivity and growth of lentil. The treatments consist of Phosphorus 20, 30, 40 kg/ha and Sulphur 10, 20, 30 kg/ha. The soil in the experimental plot had a sandy loamy texture, a pH of 7.8 that was virtually neutral, and just 0.35 percent organic carbon. The results showed that the application of phosphorus 40 kg/ha + Sulphur 30 kg/ha significantly influenced the higher plant height (39.81 cm), higher number of nodules (6.07), higher plant dry weight (14.40 g/plant), higher number of pods/plant (158.77), higher number of seeds/pod (1.94), higher 1000 seed weight (24.94 gm), higher seed yield (1.t/67 ha), and higher stover yield (2.92 t/ha). Treatment 9 (Phosphorus 40 kg/ha + Sulphur 30 kg/ha) likewise achieved greater net return (INR 68,600/ha), higher gross return (INR 1,00,200/ha), and higher B:C ratio (2.17).
