Abstract: Mango trees were sprayed with chemicals such as putrescine (0.1 mM), spermine (0.01 mM), triacontanol (750 ppm), NAA (25 ppm), CPPU (3 ppm), salicylic acid (100 ppm), ZnSO4 (0.5%), and boron (0.5%) to investigate their effect on yield and quality. Treatment T7 (NAA 25 ppm + SA 100 ppm + ZnSO4 0.5%) had the highest fruit yield (27.68 MT ha-1), longest fruit length (11.05 cm), largest fruit diameter (7.35 cm), weight (239.36 g), firmest (14.67 kg/cm2), pulp weight (164.71 g), lowest acidity (0.24%), while maximum fruit volume (223.38 ml) recorded in treatment T14 (CPPU 3 ppm + SA 100 ppm + B 0.5%). The lowest yield and quality was noticed in treatment T19 (control). The correlation of weather parameters viz., maximum temperature range (28 °C to 43.9 °C) of both seasons showed significant correlation while, minimum temperature range (9.5 to 26.1 °C) exhibited deleterious effect on yield and quality traits. The influence of average maximum RH (35 to 81%) of both seasons showed negative but significant correlation. However, positive and significant correlation was found between maximum humidity and acidity content. The average minimum RH (8 to 43%) exhibited significant effects on mango cv. Kesar.
