Effect of Plant growth regulators on growth and yield of cabbage (Brassica oleracea var. capitata L.)

Abstract

The present investigation entitled “Effect of plant growth regulators on growth and yield of a cabbage (Brassica oleracea var. Capitata L.)” is an experiment was conducted during 2020-21 at research form of Udai Pratap Autonomous College, Varanasi (U.P.). The nine treatment comprising of T1 - Control , T2 – NAA (50ppm), T3 - NAA (75ppm), T4 – NAA (100 ppm), T5 - NAA (120 ppm), T6 -GA3 (50 ppm), T7 - GA3 (75ppm), T8 - GA3 (100 ppm) and T9 - GA3 (150 ppm), were evaluated in randomised block design with three replications. The experimental finding revealed that the treatment T9 showed better response to plant growth and yield attributes. However, maximum yield 400.74 q/ha was obtained with the application of T9 (GA3 150 ppm) fallowed by T5 - (NAA 120 ppm). On the basis of economic analysis with the application of GA3 150 ppm in T9 gave maximum cost benefit ratio is 1: 2.57 During 2020-21, respectively and was found most beneficial and feasible for the cultivation of cabbage.
