Grafted Macadamia Seedlings (MRG20)

Grafted Macadamia Seedlings sold at Farmers Trend nurseries are certified and of high productive variety known as Muranga 20. The most prefered Macadamia variety in Kenya

As farmers transition from traditional crops like coffee and maize, macadamia farming is emerging as a lucrative alternative, offering a path to financial success. The reasons for this shift are clear: macadamia nuts are a high-value crop with strong global demand, fetching premium prices in the international market.

This golden opportunity isn’t without its considerations. Selecting the right macadamia seedling variety is crucial for maximizing yields and profits. Here’s where the Muranga 20 variety shines.

The Superiority of Muranga 20 Grafted Macadamia Seedlings

1. Higher Yield Potential

Muranga 20 grafted macadamia seedlings are renowned for their exceptional yield potential. These macadamia seedlings are specifically bred to produce more nuts per tree compared to traditional varieties. Farmers can expect an increase in yield by up to 40%, translating to higher income and better returns on investment.

2. Early Maturity

One of the most significant advantages of Muranga 20 is its early maturity. While traditional macadamia trees may take up to seven years to start bearing nuts, Muranga 20 seedlings begin production as early as three to four years after planting. This early return on investment is crucial for farmers seeking quicker financial gains and reduced waiting periods.

3. Disease Resistance

Muranga 20 seedlings exhibit strong resistance to common diseases and pests that affect macadamia trees. This resistance reduces the need for chemical treatments, lowering production costs and ensuring healthier, organic nuts. The robust nature of these seedlings makes them a reliable choice for farmers aiming for sustainable farming practices.

4. High-Quality Nuts

The nuts produced by Muranga 20 trees are of superior quality, characterized by their larger size, uniformity, and excellent kernel recovery rate. These attributes are highly sought after in both local and export markets, where buyers are willing to pay a premium for top-grade macadamia nuts. The high-quality output ensures that farmers remain competitive in the market and can command better prices.

5. Adaptability to Various Climates

Muranga 20 grafted macadamia seedlings are highly adaptable to different climatic conditions across Kenya. Whether in highland or lowland regions, these seedlings thrive, making them a versatile choice for farmers in diverse geographical locations. This adaptability ensures consistent production and reduces the risk associated with climate variability.

Best Ecological Conditions for Growing Muranga 20 Grafted Macadamia Seedlings

Soil Requirements

• Soil pH: Macadamia trees thrive in slightly acidic to neutral soils with a pH range of 5.0 to 6.5. It is essential to test the soil pH before planting and amend it if necessary.
• Soil Type: Well-drained, deep, loamy soils are ideal for macadamia cultivation. Avoid heavy clay soils that retain water and sandy soils that drain too quickly.

Climate and Temperature

• Temperature: Macadamia trees grow best in areas with temperatures ranging between 16°C to 25°C. They can tolerate temperatures up to 30°C, but extreme heat or frost can damage the trees.
• Altitude: Optimal growth occurs at altitudes between 600 to 1,500 meters above sea level.

Rainfall and Irrigation

• Rainfall: Macadamia trees require an annual rainfall of 1,200 to 2,100 mm, evenly distributed throughout the year. However, they are sensitive to waterlogging, so proper drainage is crucial.
• Irrigation: In regions with insufficient rainfall, supplemental irrigation is necessary, especially during dry spells and the flowering and nut development stages.

Intercropping

• Suitable Crops: Macadamia trees can be intercropped with short-term crops such as beans, peas, and vegetables during the early years before the canopy closes. This practice optimizes land use and provides additional income.
• Avoidance: Avoid planting crops that compete heavily for water and nutrients or those that may harbor pests and diseases affecting macadamia.

Planting Density and Spacing

• Planting Density: For optimal growth and yield, it is recommended to plant about 70 to 100 trees per acre.
• Spacing: The ideal spacing is 7 meters by 7 meters, providing enough room for each tree to develop a full canopy and allowing sufficient air circulation to minimize disease.

Preparing the Planting Holes

1. Size: Dig planting holes at least 60 cm deep and 60 cm wide.
2. Filling: Mix the topsoil with well-decomposed compost or manure to enrich the planting hole. Fill the hole halfway with this mixture.
3. Planting: Place the seedling in the hole, ensuring the graft union is above the soil level. Fill the rest of the hole with the soil mixture and firm it around the base of the seedling.
4. Watering: Water the newly planted seedling thoroughly to help establish the roots.

Expected Yields

• Initial Yield: Trees begin bearing nuts 3 to 4 years after planting. In the early years, yield may be modest, averaging around 10 to 30 kg of nuts per tree.
• Mature Yield: At full maturity (7 to 10 years), each tree can produce between 50 to 80 kg of nuts annually, depending on care and environmental conditions.

Additional Important Considerations

• Pruning: Regular pruning is necessary to maintain tree shape, remove dead or diseased branches, and improve air circulation.
• Fertilization: Apply balanced fertilizers based on soil test recommendations. Micronutrients like zinc and boron are crucial for macadamia health.
• Pest and Disease Management: Monitor for common pests such as thrips and stink bugs, and manage diseases like anthracnose and root rot with appropriate measures.
• Mulching: Apply organic mulch around the base of the trees to conserve soil moisture, regulate temperature, and suppress weeds.
• Harvesting: Harvest nuts when they fall naturally to the ground. Prompt collection helps maintain nut quality and reduces the risk of pest infestation.
