Abstract
A trial was conducted at the Vegetable Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences,Prayagraj (UP) during 2022. This study investigates the “Effect of Plant Growth Regulators (GA3 and NAA) on growth, yield and quality of Tomato (Solanum Lycopersicum L.).” The purpose of the study is to evaluate the plants in terms of various parameters such as plant height, survival percentage, days to first flowering, days to 50% flowering, number of flower clusters per plant, number of fruit set per cluster, number of fruits per plant, fruit weight, fruit yield per plant, fruit yield per hectare, total soluble solids (TSS), ascorbic acid, and benefit-cost ratio. The results of thestudy indicate that the application of increased percentage of NAA and GA3 significantly improvedthe growth and yield tomatoes. The highest fruit yield, fruit weight, TSS, and ascorbic acid contentwere observed in the plants treated with GA3 @60ppm + NAA @60ppm. The benefit- cost ratio wasalso found to be higher in the treated plants compared to the control. Overall, the study suggests thatthe application of GA3 @60ppm + NAA @60ppm can be an effective and sustainable method for enhancing the growth, yield, and quality of Tomatoes.
