Abstract

The current study on the “Effect of Gibberellic Acid and Hand Pollination on the Quality Parameters of custard apple (Annona squamosa L.) cv. Arka Sahan” was carried out at Krishi Vigyan Kendra, Chittorgarh and Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment was carried out in Randomized Block Design (RBD) with ten treatments and three replications. The results indicated that treatment T8 (GA3 150 ppm + hand pollination) gave maximum reducing sugar, non-reducing sugar, total sugar and ascorbic acid while these parameters were minimum in T1 (control). The titratable acidity was maximum (0.42 %) in T2 (hand pollination) and lowest in T1 (control). Maximum TSS (28.02°B) was observed in T9 (GA3 200 ppm + hand pollination). Hence, it is concluded that treatment, T8 (GA3 150 ppm + hand pollination) was found overall best with respect to the quality parameters of custard apple.

Conclusion

On the basis of the results obtained in the present investigation it is concluded that the use of GA3 with hand pollination promoted the improved of fruit quality i.e., TSS, titratable acidity, ascorbic acid, total sugar, reducing sugar, non-reducing sugar and hand pollination had a synergistic effect with gibberellic acid. The best treatment was T8 at GA3150 ppm with hand pollination, which gave best quality of fruit. Further research is needed to understand the underlying mechanisms and to optimize the concentration and timing of GA3 application and hand pollination to enhance the quality parameters.
