Abstract

This study investigates the effects of foliar application of growth regulators and micronutrients on physical characteristics of the Ewais mango cv. over two growing seasons. Treatments included Naphthalene Acetic Acid (NAA), Mepiquat chloride, Zinc sulfate (ZnSO₄), and Boron. The highest fruit weight average was recorded with Mepiquat chloride (25 mm/L) + ZnSO₄ (250 PPM), achieving 225.06 g in first season and 240.48 g in second season. The largest fruit size (203.33 cm³) was recorded with NAA (40 mg/L) and Boron (100 PPM) in the first season, while Mepiquat chloride+ Boron produced the largest size (263.33 cm³) in the second season. Fruit treated with NAA and Boron also showed the greatest length (11.23 cm) and width (7.03 cm) in first season. Pulp weight (148.91 g) was highest with Mepiquat chloride (25 mg/L) combined with ZnSO₄ .The results indicate that the combinations of growth regulators and micronutrients can significantly enhance the physical attributes of mango fruits, with treatment effectiveness varying across different environmental conditions. These findings provide valuable insights for optimizing mango yield and quality through foliar treatment strategies.
