ABSTRACT
A trial was conducted to study the effect of pre-harvest spray of chemicals on shelf-life and quality of mango cv. Kesar. The experiment involves pre-harvest spray of nutrients combined with chemicals and plant growth regulators. The treatments included GA3 25 ppm + KNO3 2% (T1), GA3 25 ppm + ZnSO4 0.05% (T2), GA3 25 ppm + Borex 1% (T3), GA3 25 ppm + CaCl2 2% (T4), 2, 4-D 20 ppm + KNO3 2% (T5), 2, 4-D 20 ppm + ZnSO4 0.05% (T6), 2, 4-D 20 ppm + Borex 1% (T7) and 2, 4-D 20 ppm + CaCl2 2% (T8). The results obtained indicated that the tree sprayed with 2, 4-D 20 ppm + ZnSO4 0.05% showed good results in fruit yield and yield attribute characters as well as shelf-life of mango. Whereas physical parameters like highest marketable fruit, minimum spoiled friut, minimum riped fruit as well as lowest days of ripening were recored in pre-harvest spray of GA3 25 ppm + Borex 1%. The quality parameters like TSS, acidity, ascorbic acid, vitamin- 'A', color, flavour, texture, taste and overall acceptability etc were performed better in pre-harvest spray of GA3 25 ppm + ZnSO4 0.05% (T2) and GA3 25 ppm + CaCl2 2% (T4).
