Dataset describing the influence of preharvest gibberellic acid application on fruiting behavior, yield and fruit biochemical properties of rambutan (Nephelium lappaceum L.)

The dataset describes how gibberellic acid application at the mature panicles (inflorescence) during the pre-flowering and the early fruiting stages augments the fruit set and retention, fruit yield and post-harvest biochemical properties of rambutan, an exotic non-climacteric tropical fruits in Bangladesh. Gibberellic acid spray at six various concentrations from 0 ppm (control) to 500 ppm revealed that 200 to 300 ppm doses had superiority over the lower and higher doses for promoting the fruit yield and quality. More specifically, fruit set, fruit retention and yield exhibited the best at 300 ppm being consonant with 200 ppm, whereas GA3 doses from 200 ppm to 500 ppm performed similarly to enhance fruit physico-chemical qualities and shelf life of rambutan. Control treatment along with 50 ppm gibberellic acid dose demonstrated inferior results for yield and fruit quality improvement of rambutan.
