tailieunhanh - Influence of different levels of pruning and growth regulators on growth and yield of guava (Psidium guajava L.) cv. ‘L-49’

The present experiment was laid out in Randomized Block Design with factorial concept (FRBD) consisting of thirteen treatments and three replications involving two factors, among them first factor contains two levels of pruning (75 cm and 100 cm) and second factor contains two levels of each growth regulators . PBZ (500 and 1000 ppm), Ethephon (500 and 1000 ppm) and GA3 (50 and 100 ppm) as well as absolute control. The results obtained from present investigation revealed that interaction effect of pruning and chemical spraying on number of fruits per shoot number of fruits per shoot (), fruits per plant (), maximum yield of fruits per plant ( kg) were found significant in pruning at 75 cm and PBZ at 500 ppm (P2S1). Whereas, the maximum fruit weight ( g) was recorded in pruning at 75 cm and GA3 at 50 ppm (P1S5). | Influence of different levels of pruning and growth regulators on growth and yield of guava (Psidium guajava L.) cv. ‘L-49’
