Research undertaken by Bangabandhu Sheikh Mujibur Rahman Agricultural University in Bangladesh aimed to tackle issues related to poor fruiting, low yield, and suboptimal edible qualities in rambutan (Nephelium lappaceum L.), a widely favored non-climacteric tropical fruit. The experiment focused on the application of gibberellic acid (GA3) to enhance fruit set, retention, yield, and post-harvest biochemical properties.
The study was carried out over two growing years (2020 and 2021) using a randomized complete block design (RCBD). GA3 was sprayed at seven different concentrations, ranging from 0 ppm (control) to 500 ppm, on mature panicles during the pre-flowering and early fruiting stages. The results indicated that concentrations of 200-300 ppm were most effective in improving fruit yield and quality. Specifically, the 300 ppm dose demonstrated the best outcomes in terms of fruit set and retention, fruit size and weight, pulp weight and thickness, pulp:peel ratio, edible portion, fruit yield, total soluble solids, and total sugars content.
Higher (400-500 ppm) and lower (50-100 ppm) doses were less effective, with the control and 50 ppm treatments showing the poorest results. The study concludes that the appropriate use of GA3 at 200-300 ppm is crucial for enhancing the yield and quality of rambutan.
