Yes, urea can be beneficial for guava trees, particularly when applied as a foliar spray. Studies suggest that urea can improve fruit retention, fruit weight, the number of fruits per plant, and overall fruit yield.
Benefits of Urea Application on Guava Trees
Research indicates that foliar application of urea can positively impact guava tree health and fruit production. Specifically, a 1.5% urea solution has demonstrated the following benefits:
- Increased Fruit Retention: Higher percentage of fruits remain on the tree until harvest.
- Enhanced Fruit Weight: Individual fruits are heavier, leading to increased yield.
- Greater Number of Fruits Per Plant: Each tree produces more fruits.
- Improved Fruit Yield: The overall harvest weight per hectare is significantly higher.
Optimal Concentration
According to research, a 1.5% urea solution appears to be an effective concentration for foliar application on guava trees. This concentration resulted in the most significant improvements in fruit set, yield, and quality in the cited study.
Application Method
The reference indicates that foliar application, spraying the urea solution directly onto the leaves, is an effective method for delivering urea to guava trees. This allows for rapid absorption of the nitrogen.
Important Considerations
While urea can be beneficial, it's essential to use it correctly. Excessive application can be detrimental. Always follow recommended guidelines and consider soil testing to determine the specific nitrogen needs of your guava trees.
