Growing Modern Mangoes ; is one of the most profitable fruit enterprises in tropical and subtropical regions. Improved mango varieties produce high yields, better quality fruits, and mature earlier than traditional mango trees. Successful mango production requires proper planting, grafting, fertilization, pruning, pest control, and orchard management.
1. Mango Planting Manual and Spacing
Site Selection
Mangoes grow best in:
- Warm climates with temperatures between 24°C and 30°C.
- Areas receiving 750–2,500 mm of rainfall annually.
- Well-drained soils.
- Full sunlight exposure.
- Slightly acidic to neutral soil (pH 5.5–7.5).
Recommended Spacing
The spacing depends on the variety and management system.
| Planting System | Spacing |
|---|---|
| Traditional System | 10m × 10m |
| Medium Density | 8m × 8m |
| High Density | 5m × 5m |
| Ultra High Density | 3m × 2m |
For most farmers, an 8m × 8m spacing is recommended because it provides adequate sunlight, air circulation, and room for tree growth.
Planting Holes
- Dig holes measuring 60 cm × 60 cm × 60 cm.
- Separate topsoil from subsoil.
- Mix topsoil with:
- 20–30 kg of well-rotted manure.
- 200 g of phosphate fertilizer.
- Refill the hole two weeks before planting.
Planting Procedure
- Plant at the beginning of the rainy season.
- Remove the seedling from the container carefully.
- Place the seedling upright in the hole.
- Fill with soil and press gently.
- Water immediately after planting.
- Mulch around the tree but keep mulch away from the stem.
2. Mango Grafting Manual(growing modern mangoes).
Grafting is the process of joining a desired mango variety (scion) to a healthy rootstock.
Importance of Grafting
- Early fruit production.
- Uniform orchard.
- Better fruit quality.

- Higher yields.
Materials Required
- Healthy rootstock seedlings.
- Mature scion sticks.
- Sharp grafting knife.
- Grafting tape.
- Polythene wrapping material.
Steps in Mango Grafting
- Select healthy rootstocks aged 6–12 months.
- Choose disease-free scion wood from a productive mother tree.
- Make clean cuts on both rootstock and scion.
- Join the cambium layers carefully.
- Wrap tightly with grafting tape.
- Cover to prevent moisture loss.
- Keep under shade until successful union occurs.
Signs of Successful Grafting
- Bud swelling after 2–4 weeks.
- Emergence of new leaves.
- Healthy green scion growth.
