Response of pre harvest spray of calcium nitrate and gibberellic acid on physical parameters of guava CV. L-49

Abstract

The objective of this study was to determine the effects of calcium nitrate, gibberellic acid and their interaction on physical parameters of guava cv. L-49. The selected trees were pre harvest sprayed with the different concentrations calcium nitrate and gibbrellic acid at the time of fruit set and 25, 15 days before harvesting during kharif season of the year 2018-19. Guava trees were sprayed with 0, 0.5, 1.0, and 1.5% of calcium nitrate and 0, 50, 100 and 150 ppm GA3. Generally higher concentration of calcium nitrate and medium concentration of gibberellic acid alone with T15 in combination of C3 + G2 were found superior over all the treatments.
