Other notable varieties include Keitt, Vandyke, and Boribo⁷. When selecting a mango variety, consider factors such as adaptation to local climate conditions, tolerance to pests and diseases, flowering and fruiting patterns, intended use (consumption or processing), and market requirements².

Climate and Soil Conditions for Mango Farming in Kenya

Mango trees flourish in tropical and subtropical climates where temperatures typically range between 24°C and 30°C⁵. It’s crucial to have a distinct dry season during the flowering and fruiting stages to minimize the risk of fungal diseases and ensure high fruit quality⁵. This dry period allows for optimal pollination and fruit development. In areas with two rainy seasons, mango trees may flower and produce fruit twice a year⁹.

While an annual rainfall of 500mm to 1,000mm is generally sufficient for mango cultivation, supplementary irrigation is often necessary, especially in drier regions or during prolonged dry spells⁵. Mango trees are deep-rooted and can tolerate drought conditions once established, but adequate moisture is essential for flowering and fruit set³.

Mangoes thrive in well-drained soils with a pH range of 5.5 to 7.5⁵. Ideal soil types include sandy loam or alluvial soil, which provide good drainage and aeration⁵. Before planting, it’s essential to conduct a soil test to assess fertility, texture, and nutrient content⁵. This information helps determine if any soil amendments are needed to optimize growing conditions.

When selecting a planting site, choose a sunny location with a gentle slope to prevent waterlogging and promote healthy root development¹⁰. The site should also be protected from strong winds, which can damage trees and reduce fruit yield¹⁰.

Mango Propagation and Planting in Kenya

Mango propagation in Kenya is primarily done through seeds, particularly for indigenous varieties². However, exotic varieties are typically propagated by grafting a scion (a piece of a desired variety) onto an indigenous rootstock². Grafting offers several advantages, including improved disease resistance, enhanced fruit quality, and uniform yield¹¹. It also allows for the production of dwarf mango trees, which require closer spacing and can be more manageable for farmers¹.

When planting mango seedlings, dig planting holes measuring 60cm x 60cm x 60cm, maintaining a spacing of 8-10 meters between holes to allow for proper growth and canopy development⁵. For dwarf varieties, closer spacing may be appropriate¹. Before planting, mix the excavated topsoil with well-rotted manure or compost to provide essential nutrients for the young trees⁵. When planting grafted trees, ensure that the graft union (the point where the scion is joined to the rootstock) is positioned above the soil surface⁵. Water the newly planted trees thoroughly and maintain regular watering, especially during the first year, to establish a strong root system⁵.

To maximize land use and generate income while the mango trees mature, consider intercropping with annual crops during the first five years after planting⁹. Suitable intercrops include vegetables, legumes, and short-duration fruit crops.

Mango Tree Care

Proper care is essential for mango trees to thrive and produce abundant, high-quality fruit. Key aspects of mango tree care include pruning, fertilization, and pest and disease control.

Pruning

Pruning plays a vital role in mango tree management. It helps increase light penetration into the canopy, which encourages flower bud formation and ultimately leads to improved yield¹². Pruning also stimulates new growth, promotes uniform annual bearing, and helps control the tree’s size, making it easier to manage and harvest¹².

Formative pruning is typically done when the tree is young. It involves cutting the main shoot at a height of 1 meter and selecting 3-4 well-spaced horizontal shoots to form the main framework of the tree¹². Subsequent pruning focuses on removing dead or diseased wood, opening up the canopy to improve air circulation and light penetration, and maintaining the desired tree shape¹². Skirt pruning, which involves removing branches at knee level (about 0.5 meters from the ground), is also recommended to improve access and maintain a clean orchard¹³.

Fertilization

Mango trees require a balanced supply of nutrients for healthy growth and fruit production. Essential nutrients can be categorized into macronutrients and micronutrients.

Macronutrients:

• Nitrogen (N): Promotes vegetative growth, leaf development, and overall tree vigor.
• Phosphorus (P): Essential for root development, flowering, and fruit set.
• Potassium (K): Plays a crucial role in fruit size, quality, and overall yield.

Micronutrients:

• Zinc (Zn): Promotes proper leaf formation and overall tree health.
• Boron (B): Enhances nutrient transport within the tree.
• Manganese (Mn): Supports photosynthesis, which is essential for energy production and growth.

Before applying any fertilizers, it’s crucial to conduct a soil test to determine the specific nutrient needs of your mango trees¹². This helps avoid over-fertilization, which can be detrimental to tree health and the environment. Young mango trees generally require higher levels of nitrogen to support rapid growth, while mature trees need more phosphorus and potassium to support fruit production¹².

Fertilizer application should be tailored to the age and growth stage of the trees. Young trees should be fertilized every 3-4 months, while mature trees typically require fertilization twice a year, once before flowering and again after harvest⁵.

Pest and Disease Control

Mango trees are susceptible to various pests and diseases that can significantly reduce yields and affect fruit quality. Common pests include mango seed weevils, fruit flies, scales, and mealybugs¹⁴. The oriental fruit fly, in particular, poses a major threat to mango production in Kenya, causing significant pre- and post-harvest losses if not effectively managed¹⁷.

Diseases such as anthracnose, powdery mildew, and bacterial black spot can also affect mango trees¹⁶. These diseases can cause leaf spots, fruit rot, and even tree death if left uncontrolled.

Integrated Pest Management (IPM) strategies are recommended for effective and sustainable pest and disease control⁷. IPM emphasizes a holistic approach that combines various methods to minimize pest and disease pressure while minimizing the use of synthetic pesticides. Key IPM practices for mango farming include:

• Monitoring: Regularly inspect trees for signs of pests and diseases. Early detection is crucial for effective control¹⁴.
• Cultural practices: Maintain good orchard sanitation by removing fallen fruit, leaves, and other debris that can harbor pests and diseases¹⁴. Proper pruning and spacing also help improve air circulation and reduce humidity, which can discourage disease development.
• Biological control: Encourage natural enemies of pests, such as ladybirds, lacewings, and parasitic wasps. These beneficial insects can help keep pest populations in check¹⁸.
• Organic pesticides: When necessary, use environmentally friendly alternatives to synthetic pesticides, such as neem oil, botanical extracts, and insecticidal soaps¹⁸.
• Chemical control: Use synthetic pesticides as a last resort, following recommended guidelines and safety precautions¹⁸.

Mango Harvesting and Post-harvest Handling

Proper harvesting and post-harvest handling are crucial to maximize the quality and marketability of your mango crop.

Harvesting Techniques

Mangoes should be harvested when they are mature but still firm¹⁹. Harvesting at the correct maturity stage ensures optimal flavor, texture, and shelf life. Maturity indicators vary depending on the variety, but common signs include a change in skin color, a slight softening of the fruit, and the ease with which the fruit detaches from the stem.

In Kenya, manual harvesting is the most common method. Farmers typically use ladders and harvesting tools, such as long poles with cutting blades or baskets, to reach the fruit¹⁹. It’s essential to handle the fruit with care during harvesting to avoid bruising or other damage that can affect its quality and marketability.

Post-harvest Practices

After harvesting, mangoes should be carefully handled to minimize losses and maintain their quality. Key post-harvest practices include:

• Cleaning: Gently wash the mangoes with clean water to remove dirt, debris, and latex residue¹⁹.
• Sorting and grading: Separate damaged or diseased fruits from healthy ones. This ensures that only high-quality mangoes reach the market.
• Draining latex: After harvesting, turn the mangoes upside down to allow any latex to drain. This prevents the latex from staining or damaging the fruit’s skin¹⁹.
• Storage: Store mangoes in a cool, shaded area to prevent rapid ripening and spoilage¹⁹. Proper ventilation is also important to prevent the buildup of heat and moisture.
• Packaging: Use appropriate packaging materials, such as crates or boxes lined with cushioning material, to protect the fruit during transportation and storage.
