EFFECT OF PLANT GROWTH REGULATORS ON GROWTH AND YIELDOF CABBAGE (BRASSICA OLERACEA VAR. CAPITATA L.)Shyam Prakash, Ankit Singh, Shashi Bala and Shivaraj Kumar VermaAbstract The present investigation entitled âEffect of plant growth regulators on growth and yield of a cabbage(Brassica oleracea var. Capitata L.)â is an experiment was conducted during 2020-21 at research form of UdaiPratap Autonomous College, Varanasi (U.P.). The nine treatment comprising of T1 - Control , T2 â NAA(50ppm), T3 - NAA (75ppm), T4 â 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 threereplications. The experimental finding revealed that the treatment T9 showed better response to plant growthand yield attributes. However, maximum yield 400.74 q/ha was obtained with the application of T9 (GA3150 ppm) fallowed by T5 - (NAA 120 ppm). On the basis of economic analysis with the application of GA3150 ppm in T9 gave maximum cost benefit ratio is 1: 2.57 During 2020-21, respectively and was found mostbeneficial and feasible for the cultivation of cabbage. |
