What Are the “Quail Egg” and “Chicken Egg” Stages?

The “Quail Egg” and “Chicken Egg” stages are crucial phases in durian fruit development after successful pollination. These stages can be divided into two key periods:

• Quail Egg Stage (Around 7-14 Days After Pollination)
  At this stage, the durian fruit is as small as a quail egg. This is the critical period for fruit selection, where weak or deformed fruits should be removed to allow the tree to focus its energy on the strongest fruits.

• Chicken Egg Stage (Around 20-30 Days After Pollination)
  The fruit grows to the size of a chicken egg. This phase requires a high supply of nutrients to support fruit development and minimize fruit drop.

Nutrient Management for Durian During the “Quail Egg” and “Chicken Egg” Stages

✅ Proper Nutrient Management

• Focus on Calcium (Ca) and Magnesium (Mg) to strengthen fruit structure, reduce premature fruit drop, and promote a firm outer shell.

• Apply Green Cal Gypsum, a high-quality source of calcium and magnesium, to improve soil conditions and enhance nutrient absorption by the roots.

• Increase Potassium (K) and Boron (B) to support fruit expansion and proper growth.

✅ Optimal Water Management

• During the Quail Egg Stage, maintain appropriate soil moisture levels—avoid excessive dryness or waterlogging.

• In the Chicken Egg Stage, ensure consistent but not excessive watering to prevent fruit drop.

✅ Pest and Disease Control

• Regularly inspect for thrips and fruit borers, which can damage young fruits.

• Use biological or appropriate chemical treatments to prevent fungal infections that may lead to fruit drop.

✅ Fruit Thinning for Better Quality

• During the Quail Egg Stage, select only the healthiest fruits and remove small or deformed ones.

• In the Chicken Egg Stage, maintain appropriate fruit spacing on branches to minimize nutrient competition.

Proper durian care during the Quail Egg and Chicken Egg stages is essential for healthy fruit growth, reducing fruit drop, and improving overall fruit quality. By applying Green Cal Gypsum to supplement calcium and magnesium, durian trees become stronger, produce higher-quality fruits, and achieve better yields efficiently.
