Proper care during the fruit development stage is crucial for durian growth, especially from the early fruit set phase to full fruit maturity. During this period, durian requires a balanced supply of nutrients to support flesh and rind formation, ensuring high-quality fruit. Effective fertilization and nutrient management help promote rapid fruit growth, firm texture, and a sweet aroma, which are essential for premium durian production.
Why Is the Fruit Development Stage Important?
The fruit development phase is when durian needs optimal nutrition to ensure healthy fruit growth. As durian progresses from small fruit to nearly full size, a well-balanced nutrient supply plays a key role in forming the rind and flesh.
- Insufficient nutrients can cause fruit drop, thin rinds, or poorly developed flesh.
- Proper nutrition ensures thicker rinds, firm and sweet flesh, and overall better fruit quality.
Key Nutrients for Durian During Fruit Development
During this stage, durian requires specific nutrients to enhance fruit quality, increase weight, and strengthen the rind and flesh.
✅ Calcium (Ca) – Strengthens the fruit rind, making it thicker and more resistant to cracking or premature fruit drop.
✅ Magnesium (Mg) – Enhances photosynthesis efficiency, promoting better starch and sugar accumulation, which results in sweeter and higher-quality durian flesh.
✅ Potassium (K) – Improves fruit weight and texture, enhancing the sweetness and aroma, which are key characteristics of premium durians.
✅ Boron (B) – Supports fruit retention by strengthening the fruit stem, reducing premature fruit drop, and ensuring healthy fruit development.
By ensuring the right nutritional balance, farmers can significantly enhance durian yield and quality, resulting in better market value and higher profits.
