Abstract:
A field experiment was conducted to find out the Potassium and Zinc levels on growth and yield of chickpea (var. Pusa 362) with nine treatments in the rabi 2020. With the different levels of Potassium (20,30,40 K₂O kg/ha) and with the application of Zinc (5,10,15 kg ZnSO₄/ha) respectively, at Crop Research Farm, Department of Agronomy, Faculty of Agriculture, SHUATS, Prayagraj, Uttar Pradesh. By all these findings maximum plant height was recorded significantly higher viz., 68.72 cm, Number of root nodules recorded (2.73), maximum dry weight was recorded (23.97 g/day), maximum crop growth rate recorded (9.51 g/day/m²) and maximum relative growth rate recorded (0.02 g/g/day) with the application of treatment combination Potassium 40 kg/ha + Zinc 15 kg/ha. Maximum yield attributes viz., seed yield (2916.67 kg/ha), stover yield (5014.66 kg/ha) and harvest index (36.76) and economics viz., Gross return 102083.45/ha, net return 61600.18/ha and B:C ratio 1.53 was recorded in treatment with the application of Potassium 40 kg/ha + Zinc 15 kg/ha. Therefore, application of Potassium 40 kg/ha + Zinc 15 kg/ha was more productive and economically feasible.
