Abstract

The present investigation was carried out at the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during Kharif 2021-22 with a view to identify the effects of different doses of plant growth regulators on growth, yield and quality of Tomato variety TMTH-288. The experiment was laid in Randomized block design with 13 treatments and 3 replications with different combination in nano fertilizers. Under this experiment, overall, 13 combinations was taken including control. PGRs comprised of GA3, 2,4-D, Triacontanol and NAA were given. According to the current research, the current study found that the use of plant growth regulators (PGRs) had a significant positive impact on the growth and yield of tomato. Among the treatments tested, T3 (GA3 40 ppm) showed the most favorable results in terms of plant height, early flowering and maturing. It also demonstrated superior performance in terms of fruit weight, polar and radial length of fruit, number of fruits per plant, and yield per plant.

Keywords: GA3, 2,4-D, NAA, triacontanol, tomato
