Effect of plant growth regulators, micronutrients and photothermal regimes on biochemical parameters of brinjal (Solanum melongena L.)

Abstract

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 highest dry matter percent in fruit was observed in D1T9- GA3 (50ppm) + Boron (100ppm). The highest total phenol content was noted under D1T1 (control) which was transplanted on 15th November and maximum ascorbic acid content was recorded by the treatment combination of GA3 (25 ppm) + Boron (100 ppm) (D1T8).
