Early fruit production for mango ‘Buoi’ to improve growers’ income in the areas of water scarcity in the southeastern region of Vietnam.
The experiment was aimed to develop practices package for early production to promote the income of mango growers in the areas of water scarcity of the southeastern Vietnam. Forty healthy ten-year-old mango trees c.v. ‘Buoi’ were selected and laid out in a RCB design with five treatments, four replications and eight trees per each treatment. PBZ was soil drenched as the young leaf reached the 15-day; 30-day; 45-day and 60-day stages and compared to untreated trees as the control. The results revealed that application of PBZ promoted earlier flowering 80 days than as compared to the untreated trees. Additionally, number of flower cluster per tree; number of fruit per tree, fruit weight and yield increased significantly as compared to the control. PBZ application at 45-day-old young leaf was the best in term of economical profit.
