Mango nutrition and biostimulant programme
How mango growers in Gujarat, Maharashtra, Andhra Pradesh, Karnataka, Uttar Pradesh and across India use humic acid, seaweed, amino acids and biofertilisers, and how our Immunity Mango Special came about.
Stage by stage
| Stage | What the crop needs | Inputs growers use |
|---|---|---|
| Post-harvest and pruning | Tree recovery and root health | Humic acid, mycorrhizae, organic manure |
| Vegetative flush | Healthy new shoots | Amino acids; zinc if deficient |
| Flowering | Strong, even flowering | Seaweed extract; boron if deficient |
| Fruit set and development | Holding fruit and sizing | Seaweed and amino acid sprays; potash |
Results vary with crop, soil, weather and practice. Follow the label, run a small trial first and scale what works on your farm. Nothing on this page is a guarantee of yield.
Mango problems and our programme
Problems growers bring to us
- Tree decline and mortality
- Alternate (biennial) bearing
- Flower and fruit drop
- Small fruit and poor quality
- Orchards that no longer break even
Immunity Mango Special
Immunity Mango Special was developed for mango growers across India dealing with tree decline and mortality, poor growth, alternate bearing, flower and fruit drop, small fruit and poor quality, often on orchards that no longer broke even. It is a season-long programme from post-harvest care to fruit development.
Distributors can carry this programme in territories where we do not yet have a presence, and brands can have it made under their own label.
Mango questions
What is the best fertilizer for mango trees during flowering?
Mango at flowering mainly needs boron where it is deficient, and many growers use seaweed extract to support flowering and set. Avoid heavy nitrogen at this stage, which pushes leaf growth instead of flowers.
Which fertilizer should be used after mango flowering?
After set, growers support fruit development with potash, seaweed extract and amino acid sprays, and keep the root zone moist and healthy.
How can I reduce fruit drop in mango?
Fruit drop has many causes: water stress, nutrient gaps such as boron, heat, pests and disease. Steady irrigation, balanced nutrition and seaweed or amino acid sprays at set are common parts of a programme; persistent drop needs a field diagnosis.
Which organic fertilizer is best for mango trees?
Well-rotted organic manure with humic acid and biofertilisers such as mycorrhizae, PSB and Azotobacter after harvest is a common organic base for mango.
Can alternate bearing in mango be corrected?
Alternate bearing is influenced by variety, crop load and tree health. Good post-harvest nutrition and root health help trees carry a more regular crop, but it cannot be removed entirely by any input.
