| Abstract | ||||
| In the two seasons of 2023–2024, an experiment was conducted in Balat district of Afaq Farm, located in New Valley Governorate, Egypt to look at how gibberellin and naphthalene acetic acid affect in Mango Naomi cv. in fruit quality and yield. Three replications and seven treatments NAA (20, 40 and 80 ppm) and GA3 (25, 50 and 100 ppm) compared with control (water spray) were used in a complete randomized block design (RCBD) experiment. Together with total soluble solids, sugar content, and vitamin C, these treatments markedly increased fruit set, fruit retention, and yield compared with control. According to the current findings, spraying NAA at 40 or 80 ppm greatly increased fruit set, fruit retention, and yield compared to spraying water (control); on the other hand, spraying GA3 at 50 or 100 ppm was found to be more effective on fruit retention and fruit quality. However, the fruit quality improved more successfully when GA3 was sprayed at 50 or 100 ppm. There were no appreciable changes as a result of raising the GA3 or NAA concentrations from 50 to 100 ppm or 40 to 80 ppm. Therefore, using 40 ppm NAA or 50 ppm GA3 for spraying is better from an economic perspective. The productivity and quality of Naomi mango trees can be effectively increased by spraying GA3 and NAA. | ||||
