Abstract:
A field experiment was conducted to find out the Influence of plant growth regulator (TA41) on growth and yield of Chickpea (var. RVG 202) with seven treatments in the rabi 2021. With the different levels of Soil drenching (5.0,7.5,10.0 TA-41lit/ha) and with the foliar application of TA-41 (200,300,400 ml/15lit/acre) 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., 55.89 cm, maximum dry weight was recorded (46.23 g/day), maximum crop growth rate recorded (23.67 g/day/m2) and maximum relative growth rate recorded (0.02 g/g/day) with the application of treatment combination TA41 at 400ml in 15lit of water. Maximum yield attributes viz., seed yield (2356.67 kg/ha), stover yield (4561.67 kg/ha) and harvest index (39.72) and economics viz., Gross return 122471.005/ha, net return 80514.735/ha and B:C ratio 1.91 was recorded in treatment with the application of TA41 at 400ml in 15lit of water. Therefore, application of TA-41 at 400ml in 15lit of water was more productive and economically feasible.
