Abstract

The current study was conducted from 2019 to 2020 in a well-established ber orchard at the College of Horticulture Chandra Shekhar Azad University of Agriculture and Technology in Kanpur, Uttar Pradesh. A total of 13 uniformly sized and vigorous ber trees were chosen, and different nutrient concentrations of GA3 (10, 15 and 20 ppm), NAA (20, 30 and 40 ppm), and urea (1.0, 1.5 and 2%) were sprayed on them. Thirteen treatments that were reproduced three times were used in the CRD (Completely Randomized Design) structure of the study. Fruits were examined in a laboratory for their various features. The present study's findings showed that the use of GA3 20 ppm + NAA 40 ppm + urea 2% (T12) significantly improved the fruit characters of fruit set (170), fruit drop (84.25%), fruit retention (15.75%), volume (15.65 cc, length (4.45cm), weight (15.4 g), diameter (2.98 cm), pulp weight (14.38 g), and pulp stone ratio (14.10).

Conclusion

In this study, a number of parameters changed in response to the application of plant growth regulators, including GA3, NAA, and urea, as well as their combination treatments. The combined treatments of GA3 20 ppm + NAA 40 ppm + urea 2% significantly improved the fruit characters of fruit set (170), fruit drop (84.25%), fruit retention (15.75%), volume (15.65 cc, length (4.45cm), weight (15.4 g), diameter (2.98 cm), pulp weight (14.38 g), and pulp stone ratio (14.10). According to the findings' scenario, the current trial demonstrated that the combined treatment of (GA3 20 ppm + NAA 40 ppm + urea 2%) was more effective. Therefore, it is suggested that researchers, orchardists, farmers, and students spray this treatment on Ber trees in order to boost productivity and raise profits.
