Abstract
A field experiment was carried out to assess the growth performance and yield of tomato cv. Srijana as influenced by various concentrations of gibberellic acid (GA3), during the period from February 2022 to June 2022 in Nilkantha, Dhading, Nepal. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications and five treatments. The treatments consisted spray of gibberellic acid of various concentrations i.e., 0 ppm (control), 20 ppm, 30 ppm, 40 ppm and 50 ppm. A single spray was administered 15 days following the transplantation of tomato plants in the main field. The results revealed that the tomato growth and fruit yield were significantly influenced by the levels of GA3. The highest plant height, days spanned to the first flowering, number of flower clusters per plant, number of flowers per plant, number of fruits per plant and fruit yield were observed in the 50 ppm GA3 treatment, while the lowest values were seen in the control group (0 ppm GA3). It could be suggested that the production of tomato could be improved by the application of GA3 @ 50 ppm in the field conditions of Dhading, Nepal.
