Abstract:
A field experiment was conducted during Rabi season of 2021 at experimental field of the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj and Uttar Pradesh, India to determine the “Effect of potassium and sulphur on growth and yield of Chickpea (Cicer arietinum L.)”. The experiment consisted of 3 levels of potassium 10 kg/ha, 15 kg/ha, 20 kg/ha and 3 levels of sulphur fertilizer of 20 kg/ha, 25 kg/ha and 30 kg/ha. The experiment was laid out in Randomized Block Design (RBD) with three replications. Full doses of Nitrogen, Phosphorus and Potassium fertilizers were applied as basal. Variety used was Pusa 372. Report of the study indicate that, among different levels of potassium and sulphur the treatment with potassium at 20 kg/ha and sulphur at 30 kg/ha produced significantly highest plant height (51.63 cm), higher number of nodules (29.46), dry weight/plant (25.05 g), highest crop growth rate (12.56), highest number of pods per plant (45.74), number of seeds per pod (1.88), seed yield (2.03 t/ha), stover yield (4.45 t/ha), and Harvest index (31.29%). However, the treatment with potassium at 20 kg/ha and sulphur at 30 kg/ha was found to be effective in highest gross return (1,23,260.4 INR/ha), net return (87,830.4 INR/ha) and Benefit cost ratio (2.47) when compared to the other treatments.
