Preharvest application of ethephon improved growth, maturity and quality of banana

Abstract

Poor yield, non-uniform ripening, and delay in maturity are some serious issues faced by commercial banana growers in the country. This research was conducted in a commercial banana orchard of Chitwan from December 2021 to April 2022 in order to study the effect of different doses of ethephon on growth, maturity, and quality of banana. Five different doses of ethephon (200, 400, 600, 800, 1000 ppm) were sprayed on a banana bunch at 15th days after shooting which were compared with the control (no ethephon treatment) in RCBD design.  The maturity of the bunch was significantly hastened at a higher concentration of ethephon (above 600 ppm). Fruit length and fruit weight were also observed higher at 600 ppm (10.21 cm and 62.68 g) and 800 ppm (10.67 cm and 63.26 g) ethephon spray. The bunch treated with 600 ppm ethephon had the highest TSS (10.78oB and 23.27oB at 0 and 5 days of storage, respectively) and PPR (1.65). Considering quantitative and qualitative parameters, preharvest ethephon spray @600 ppm significantly improved growth, maturity, and quality of banana fruits.
