Mango is one of the most important fruit crops in India and is often called the “King of Fruits.” It grows well in many climates, but proper irrigation plays a key role in getting healthy growth and good fruit yield. Many farmers either over-irrigate or under-irrigate their mango orchards, which affects flowering, fruit setting, and fruit quality. Therefore, understanding when and how much water to give is important for successful mango cultivation.
1. Water Requirement Based on Plant Age
The irrigation needs of mango plants change as they grow:
Young Plants (1–3 years):
Young mango plants have small roots and need regular watering to establish themselves. Water should be given every 5 to 7 days during summer and every 10 to 15 days during winter. However, avoid waterlogging around the stem.
Middle Age Plants (4–7 years):
These plants need slightly less frequent irrigation, but water should be given deeply so that roots grow well. Irrigation once in 12 to 15 days is usually enough.
Fully Grown Trees (8 years and above):
Mature trees do not need frequent irrigation except during flowering and fruit development. Deep irrigation once every 15 to 20 days is suitable in dry seasons.
2. Important Stages for Irrigation
Certain growth stages in mango require special attention:
Before Flowering (December–January):
Reduce or stop irrigation at this time to encourage flowering. Excess water during this stage leads to more leaf growth instead of flowers.
During Flowering and Fruit Setting:
Resume irrigation lightly to avoid flower drop. Water stress at this stage can reduce the number of fruits.
During Fruit Development (March–May):
Water regularly, as this is when fruits grow in size. Lack of water leads to fruit drop, small fruits, or wrinkles.
3. Best Irrigation Methods
Basin Irrigation:
Most common method in traditional orchards. Make small basins around the tree and fill with water. However, care must be taken to avoid water stagnation.
Drip Irrigation:
Highly recommended because it saves water and provides moisture directly to the root zone. It also allows fertilizer application through water (fertigation) which improves growth.
Ring Method:
Create a circular ring around the tree and irrigate within the ring. This avoids water contact with the trunk and prevents fungal diseases.
4. Mulching to Conserve Moisture
Mulching helps keep soil moist for a longer time. Farmers can use dried leaves, straw, coconut husk, or black plastic mulch around the plant. Mulching is especially useful in dry regions.
5. Avoid Over-Irrigation
Over-irrigation weakens the root system, increases disease risk, and causes fruit cracking. Always check soil moisture before watering again. If the soil feels moist 5–10 cm below the surface, irrigation can be postponed.
Conclusion
Irrigating mango plants properly is essential for healthy tree growth and better fruit yield. The key is to water based on plant age and growth stage, avoid excess water during flowering, and ensure regular watering during fruit formation. Using drip irrigation and mulching can help save water and maintain soil moisture. With careful planning, farmers can improve mango productivity and fruit quality.
