The study tested the effects of paclobutrazol on mango trees to improve fruit yield and quality. Different amounts of paclobutrazol were applied to the soil around the trees, and the results showed that using 30ml per tree led to the best outcomes. This treatment reduced tree growth, increased flowering and fruit production, and improved the taste and nutritional content of the fruit. Therefore, applying 30ml of paclobutrazol per tree can help increase mango yield without compromising fruit quality.
