Effect of micronutrients and PGR on growth and yield of tomato (Solanum lycopersicum L.) Variety Azad-T6

Abstract

The present investigation entitled “Effect of micronutrients and PGR on growth and yield of tomato (Solanum lycopersicum L.) Variety Azad-T6” was carried out during the rabi season 2018-19 and 2019-20 both the year same time at Department of Vegetable Science Kalyanpur Chandra Shekhar Azad University of Agriculture & Technology Kanpur U.P (208024) India. Experiment was laid out in randomized block design (RBD) with eleven treatments in replicated three times consist of two levels of each micronutrients and growth regulators with control i.e. T0: Control, T1: GA3 50ppm, T2: GA3 100ppm, T3: NAA 50ppm, T4: NAA 100ppm, T5: ZnSO4 0.5%, T6: ZnSO4 1%, T7: Boric acid 50ppm, T8: Boric acid 100ppm, T9: FeSO4 100ppm and T10: FeSO4 150ppm. Significantly differences were found for plant growth and yield parameters. The highest plant height (cm), number of branches plant-1, number of flower cluster-1 and number of cluster plant-1 was recorded in T2: GA3 100ppm. The application of T2: GA3 100ppm was found early days to 50%flowering, days to first fruit set, no. of fruit per cluster, no. of fruit plant-1, average fruit weight (g), fruit length (cm), fruit width (cm), fruit yield plant-1 (kg), fruit yield plot-1 (kg) and fruit yield (q ha-1). Revealed that the use of GA3 concentration of 100ppm, considerably increased the vegetative growth and yield parameters and significantly increased growth and yield parameters.
