Effect of Different Plant Growth Regulators, Micronutrients and Photothermal Regimes on Growth, Phenological and Yield Characters of Brinjal (Solanum melongena L.)

An investigation entitled “Effect of different plant growth regulators, micronutrients and photothermal regimes on morphological and phenological characters of Brinjal (Solanum melongena L.)” was conducted at Horticulture Complex, Department of Horticulture, College of Agriculture JNKVV, Jabalpur (M.P.) during the year 2018-19. The experiment consists of forty five treatments comprising plant growth regulators, micronutrients and different photothermal regimes and was laid out in randomized block design having three replications. There were two plant growth regulators Brassinosteroids (0.5µM, 1.0µM), GA3 (25 ppm, 50 ppm) and two micronutrients Boron (100 ppm), Molybdenum (2.0µmol/l) were use with different combinations and were applied by foliar application on 15th November, 30th November and 15th December to assess the effect on growth and yield of brinjal. The investigation revealed that, the vegetative growth observations (plant height of plant at 30, 60 and 90 DAT, number of primary branches per plant and number of flower per cluster), phenological observations (viz. minimum days to flower initiation, days to 50% flowering, days to first picking) and yield per plot was reported in treatment where plant has been sprayed with T9 (GA3 (50ppm) + Boron (100ppm) whereas the control was lowest.
