Mangoes Farming Guide
Mangifera indica
57 million tonnes produced globally — the King of Fruits
Mangoes are the most popular tropical fruit in the world, with India producing over 40% of the global supply. Called the "King of Fruits" across South Asia, mangoes have been cultivated for over 4,000 years. Each mango-growing region has its prized varieties: Alphonso and Kesar in India, Sindhri and Anwar Ratol in Pakistan, Apple Mango in Kenya, and Tommy Atkins in Brazil. Mango trees are long-lived perennials that can produce fruit for 100+ years, making them a generational investment for farming families.

Mangoes Growth Stages — What to Do at Every Stage
Planting & Establishment
Years 1-3What to do
Plant grafted saplings (not seedlings) at 8x8m to 10x10m spacing (40-65 trees/acre). Dig pits 1x1x1m, fill with topsoil + 20kg FYM + 500g SSP per pit. Plant at the onset of monsoon. Provide shade for the first summer. Basin irrigation.
Watch for
Stem borer in young trunks. Gummosis (amber-colored gum oozing from bark). Sunburn on young trunks — whitewash trunk with lime. Mealybug crawling up the trunk.
Vegetative Flush
Post-monsoon (September-November)What to do
This is when the tree puts out new leaf growth. Apply NPK fertilizer after the monsoon harvest season. Maintain clean tree basin. Prune overcrowded, dead, or diseased branches after harvest. Shape the canopy for light penetration.
Watch for
Powdery mildew on new flush in humid conditions. Leaf hopper and thrips damage on young leaves. Anthracnose leaf spots.
Flowering (Panicle Emergence)
December-February (South Asia)What to do
Flowering is triggered by cool night temperatures (below 15 degrees C) following a dry period. Do NOT irrigate during flower induction. Spray sulfur or carbendazim at panicle emergence to control powdery mildew. Spray imidacloprid for hopper control.
Watch for
Powdery mildew (white powder on panicles) — the most destructive flowering-stage disease. Mango hoppers sucking sap from flowers and secreting honeydew. Malformation (bunchy top) causing deformed, sterile panicles.
Fruit Set & Development
February-May (South Asia)What to do
Resume irrigation after fruit set. Apply potassium-rich fertilizer. Thin fruits if set is very heavy (to improve size). Protect developing fruits from fruit fly by wrapping or bagging high-value fruits. Apply 2-3 sprays against anthracnose.
Watch for
Fruit drop (physiological — only 1-2% of flowers set fruit naturally). Fruit fly (Bactrocera dorsalis) laying eggs in developing fruits. Anthracnose causing black spots on fruits. Stone weevil damage.
Ripening & Harvest
May-July (South Asia)What to do
Harvest when the fruit shoulder fills out and skin color begins to change. Use picking poles with net bags for high fruits — never shake the tree. Post-harvest hot water treatment (52 degrees C for 5 min) controls anthracnose and fruit fly. Ripen in ventilated rooms at 20-25 degrees C.
Watch for
Sap burn (latex injury) on fruit skin — harvest in the morning when sap flow is less. Internal breakdown from heat stress. Fruit fly larvae inside apparently healthy fruit. Stem-end rot in storage.
Common Mangoes Diseases — Identification Guide
Powdery Mildew
Oidium mangiferae
What you will see
White, powdery fungal growth covering panicles (flower clusters), young fruits, and new leaves. Infected flowers drop without setting fruit, causing up to 80% crop loss. Young fruits develop a whitish coating and fall off. Leaves curl and become distorted.
Conditions that favor it
Cool nights (15-20 degrees C) with high humidity and dry days. Most severe during flowering (January-March in South Asia). Cloudy weather with morning dew. Does NOT need rain — dry, humid conditions are sufficient.
Anthracnose
Colletotrichum gloeosporioides
What you will see
Black, sunken spots on ripe fruits that enlarge and merge. On flowers, causes dieback (blossom blight). On leaves, irregular brown spots with shot-holes. Latent infections on green fruit become visible only after ripening — a major post-harvest problem.
Conditions that favor it
Warm (25-30 degrees C), wet conditions with rain during flowering and fruit development. Rain splash spreads spores. Latent infections established during development remain dormant until ripening.
Mango Malformation
Fusarium mangiferae
What you will see
Vegetative malformation: compact, bunchy growth of vegetative shoots ("witches broom"). Floral malformation: thickened, clustered, sterile panicles that do not set fruit. Affected panicles remain on the tree and become a source of inoculum. Can affect 50-80% of panicles.
Conditions that favor it
Spread by the mango bud mite (Aceria mangiferae). More severe in northern India and Pakistan. No effective chemical cure — management relies on pruning affected panicles 15cm below the malformed tissue and destroying them.
Bacterial Canker
Xanthomonas citri pv. mangiferaeindicae
What you will see
Raised, dark brown to black, angular lesions on leaves with yellow halos. On fruits, star-shaped cracks exuding gummy substance. Stem cankers ooze bacterial exudate. Severe on young trees.
Conditions that favor it
Warm, wet, windy conditions. Windblown rain creates wounds for bacterial entry. More severe in tropical, high-rainfall areas (coastal regions). Spreads through contaminated pruning tools.
Common Mangoes Pests — Identification & Damage
Mango Hopper (Idioscopus spp.)
Damage
Both nymphs and adults suck sap from flower panicles, young shoots, and leaves. Hoppers secrete honeydew that promotes sooty mold growth, blackening flowers and blocking light. Heavy infestations cause 40-60% flower and fruit drop.
How to identify
Wedge-shaped, green to brown insects (3-5mm) found on the underside of leaves and on panicles. Shake a panicle and they jump off. Honeydew drops and sooty mold on leaves below panicles are telltale signs. Spray at panicle emergence and again at full bloom.
Fruit Fly (Bactrocera dorsalis)
Damage
Female flies puncture developing and ripe fruits to lay eggs. Larvae (maggots) feed inside the fruit, causing it to rot from within. A single fruit can contain 50+ maggots. The most important quarantine pest restricting mango exports.
How to identify
Medium-sized (8mm) flies with yellow and dark brown markings. Oviposition puncture marks on fruit skin. Cut suspect fruits — white maggots feeding inside. Use methyl eugenol traps (attract males) for monitoring. Threshold: 5 flies per trap per week.
Mango Mealybug (Drosicha mangiferae)
Damage
Nymphs climb the trunk during winter and infest panicles and young fruits, sucking sap and secreting honeydew. Heavy infestations cause flower and fruit drop. Honeydew promotes sooty mold.
How to identify
White, cottony, oval insects (5-10mm) clustered on panicles, shoots, and trunk. Nymphs emerge from soil in winter and crawl up the trunk. Apply sticky bands (alkathene sheets with grease) around the trunk in December to prevent climbing.
Mangoes Nutrient Management — NPK Guide
Nitrogen
200-400g N/tree/year for bearing trees (increase with tree age)
Phosphorus
100-200g P2O5/tree/year
Potassium
200-400g K2O/tree/year
Application Timing
Split annual fertilizer into 2 doses: first dose (50% NPK) after harvest (June-July), second dose (50%) in October before flowering. Apply in a ring trench 1.5m from the trunk. For young trees: 100g N, 50g P2O5, 100g K2O per year of age. Apply 20-30 kg FYM per tree annually. Micronutrients: zinc sulfate and borax foliar sprays during panicle emergence improve fruit set.
Mangoes Irrigation Schedule
Total Water Requirement
40-60 inches (1000-1500mm) annual water requirement
Critical Stages
Post-fruit-set to fruit development (March-May) is the highest water-demand period. However, a dry stress period (2-3 months before flowering) is ESSENTIAL to trigger flowering. Irrigating during the flower-induction period (November-January in South Asia) promotes vegetative growth instead of flowering.
Irrigation Frequency
Basin irrigation every 10-15 days during fruit development. Stop irrigation 2-3 months before expected flowering to induce water stress. Resume after fruit set. Drip irrigation (60-80 liters/tree/day during fruit development) is most efficient.
Mangoes Economics — Cost, Yield & Profit
Cost per Acre
$500-1,500/acre/year (established orchard)
Yield per Acre
3-8 tonnes/acre (mature trees)
Revenue per Acre
$2,000-8,000/acre
Profit per Acre
$1,500-6,500/acre
Regional Context
Mango is one of the most profitable fruit crops in the tropics. Premium varieties like Alphonso (India), Sindhri (Pakistan), and Apple Mango (Kenya) command $1-4/kg at farm gate. Export-quality mangoes fetch $2-6/kg. However, the mango market is highly seasonal and wastage is high (20-40% post-harvest losses in developing countries). Investment in hot water treatment, cold chain, and export certification (GlobalGAP) can dramatically increase returns. Orchard establishment costs are $1,500-3,000/acre with no significant income for 4-5 years.
Frequently Asked Questions — Mangoes Farming
Why is my mango tree not flowering?
The most common reason for no flowering is continuous irrigation or rain during the flower-induction period. Mango trees require 2-3 months of dry stress (October-December in South Asia) to initiate flower buds. Other causes: (1) Excessive nitrogen fertilization promotes leaf growth over flowering. (2) Young trees (under 5-6 years for seedlings, 3-4 for grafted) may not be mature enough. (3) Heavy fruit load the previous year causes "alternate bearing" — the tree rests. (4) Dense canopy blocks light to inner branches. Solutions: withhold irrigation from October, reduce nitrogen, prune for canopy opening, and apply paclobutrazol (5-10g per meter canopy diameter) as a soil drench in September to promote flowering.
How do I control mango fruit fly?
Mango fruit fly (Bactrocera dorsalis) is managed through an area-wide integrated approach: (1) Sanitation: collect and destroy all fallen fruits daily (bury 50cm deep or drown in water). (2) Bait sprays: mix protein hydrolysate bait (GF-120 or homemade from jaggery/molasses) with spinosad insecticide; apply to tree trunks weekly from fruit pea-size stage. (3) Male annihilation: hang methyl eugenol traps (20-25 per acre) to catch and kill male flies. (4) Fruit bagging: cover individual fruits or clusters with paper or muslin bags at marble stage — most effective for high-value export fruit. (5) Post-harvest: hot water treatment (48 degrees C for 60 minutes or 52 degrees C for 5 minutes) kills eggs and larvae. Chemical sprays on fruits are not recommended due to residue concerns.
What is alternate bearing in mangoes and how to manage it?
Alternate bearing is the tendency of mango trees to produce heavily one year ("on year") and very little the next ("off year"). It occurs because a heavy crop exhausts the tree's carbohydrate reserves, leaving insufficient energy to initiate flower buds for the next season. Management: (1) Fruit thinning in the "on year" — remove 30-50% of panicles at pea stage to reduce stress. (2) Apply extra fertilizer (especially potassium) immediately after a heavy harvest. (3) Apply paclobutrazol (Cultar) to soil in September during the "off year" to promote flowering. (4) Prune 25% of branch tips after harvest to stimulate new shoot growth that can flower. (5) Maintain consistent nutrition and irrigation year-round. Some varieties (Alphonso, Langra) are more alternate-bearing than others.
