Effect of micronutrients and PGR on growth yield and quality of tomato

Abstract

The present investigation entitled Effect of micronutrients and PGR on growth, yield and quality of tomato (Solanum lycopersicum L.),Variety Azad-T6 was carried out during the rabi season of October to Jan, 2018-19 and October to Jan 2019-20 both the year same time at Vegetable Research Farm of the Department of Vegetable Science Kalyanpur C. S. Azad University of Agriculture and Technology Kanpur U.P (208002) India. Experiment was laid out in a randomized block design (RBD) with eleven treatments 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 parameters. Plant height (cm), number of branches plant-1, number of flower cluster-1, number of cluster plant-1, was recorded in T2: GA3 100ppm. The T2: GA3 100ppm was found early days to 50%floweringand days to first fruit set, yield attributes viz., 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) of tomato and Significantly differences was found for fruit quality and self life parameters of tomato. Application of GA3 100ppm concentration showed significant effect on fruit quality and self life viz., days to first fruit picking, fruit cracking (%), fruit drop per plant, days to last fruit picking, tss (0brix), self life at ambient room temperature and ascorbic acid (mg/100gm) of tomato Variety Azad-T6.Revealed that the use of GA3 concentration of 100ppm, considerably increased the vegetative growth parameters and significantly increased growth, flowering, yield and fruit quality of tomato newline
