The Perfect Pair, Double Yields: How Bananas Boost coffee farming for maximum Yield and profit

Did you know that coffee thrives well under shade and the bananas provide the perfect shade? Climate changes have impacted sustainability and global temperatures hence a need to embark on sustainable agricultural practices like Intercropping.

Imagine walking into our restaurant and you are served two dishes. One plate with honey-glazed fried chicken and another with well-boiled spiced chicken with thick soup. you now have a choice of having one or both. Yes, you are right I would choose both.  

This time am not talking about food but Banana (Musa spp)- Coffee (Coffea spp) Intercropping. Both crops contribute greatly to the country’s exports and smallholder farmer livelihoods throughout the year. Coffee exports bring over 23% of the foreign exchange brought to the country while bananas which are a stable food in the country provide food security for the locals.

The Background.

Uganda is landlocked with a young population of 45.9 million people. Like many other African countries, Agriculture is the backbone of Our country’s economy. It should be noted that agriculture employs about 70% of the population, and 72% of the land in Uganda is arable land. (NEMA 2020, UBOS 2024). 5.7 million acres of the country’s land are under annual crops while 2.2 million acres are under permanent crops.

The International Institute of Tropical Agriculture (IITA) is at the forefront of researching the benefits of traditional Coffee Banana Intercropping (CBI). CBI aims to archive the climatic pillars of smart agriculture, but also contributes to soil health, boots yield, and improves farmers’ livelihood. All are suitable for the small-scale farming system in Uganda.

The Science of Growing coffee and bananas.

The main types of coffee (Coffea) widely grown by farmers in Uganda are Robusta (Coffea canephora) and Arabica (Coffea arabica) coffee. Coffee is a tropical evergreen shrub-like plant. it mainly grows in tropical and subtropical climates. Climatic factors suitable for coffee growth are temperature (23 and 28 °C) and rainfall (1,500 to 2,000 mm) per year. Altitude is required for the growth of coffee. the arabica coffee requires a higher altitude of (2,000–6,500 feet) and more rain. it is the most vulnerable to pests and hence needs more attention than robusta. Coffee is grown for the seeds, or beans, which are roasted, ground, and sold or exported.

The banana (Musa spp) is a perennial plant with a wide palm-like that stays productive by self-propagation all year round. Banana. Bananas do not grow from a seed but from a bulb or rhizome, and it takes 9 to 12 months from sowing a banana bulb to harvesting the fruit.

The banana plants thrive in tropical regions where the average temperature is (27° C -30° C). temperature above or below affects banana production. the yearly rainfall is between 78 and 98 inches is a requirement. Most bananas exported are grown within 30 degrees on either side of the equator.

Can coffee be intercropped with bananas?

The crops share conditions of growth and their physical traits make them a suitable pair. How so you may ask? Let me go ahead and elaborate, coffee is climate-sensitive and needs shade and humid dense environments which the bananas provide with their broad long leave. The leaves protect the coffee plants from direct sunlight and create a cool environment underneath where the coffee thrives. I hope we have our answer, Moving on.

Why are bananas grown with coffee?

Productivity.

The coffee production chain is made of both commercial and small-scale farmers. 23% of these farmers are small-scale. The fact that coffee-growing communities still face food insecurity shows a lack of extra resources for the farmer to provide for their families. Amidst climatic changes research by IITA has shown that CBI increases the productivity per area by over 50% without jeopardizing the coffee Yield. This is in comparison to the mono-cropping of coffee or bananas. Integrating Bananas makes the coffee production system more diverse, and low-risk and guarantees food security in the community.

Sustainability and Resilience.

Banana has highly hydrated stems that store water during the dry season so it reduces competition for water between the plants. Bananas also provide reasonable shade coverage which we well know is climate sensitive hence increasing resilience throughout the dry period.

The Intercropped bananas provide leaves and stalks that can be used as mulch between the coffee trees. This mulch improves soil health and suppresses weeds, which would have been manually weeded by farmers. As a result, farmers found that coffee-banana intercropping decreased their workload even as this practice reduced losses associated with weed infestations.

Economically.

Farmers found that intercropping coffee and bananas reduced the spread of the disease and the additional income from bananas buffered the financial impact of coffee production losses due to the disease. In newly established coffee farms, bananas can offset cash flow constraints in the early years before the coffee becomes productive.

Picture a tropical garden where bananas and coffee trees thrive side by side, creating a lush, productive space. Growing these two crops together isn’t just rewarding—it’s a perfect balance of fruit and flavor. Whether you’re a gardening pro or a beginner, this duo can turn your garden into a mini paradise. Let’s dive into how you can grow bananas and coffee together!

Growing bananas and coffee together can be a fun and rewarding challenge, as both plants thrive in similar tropical and subtropical environments.

  Step-by-step guide to help you grow them together successfully:

Select the Right Location.

1. Climate: Both bananas and coffee plants prefer warm, tropical climates. They thrive in temperatures between 60-85°F (16-29°C) with high humidity.
   1. Sunlight: Bananas need full sun, while coffee plants prefer partial shade (especially when young). Ideally, you can create a balance by planting bananas in spots that get plenty of sunlight and coffee in slightly shaded areas.
   1. Soil: Both plants prefer well-draining, fertile soil rich in organic matter. You can improve soil quality with compost or organic matter to ensure they both get the nutrients they need.

• Prepare the Soil
  • Test pH: Both bananas and coffee plants prefer slightly acidic soil, with a pH of 5.5 to 6.5.
  • Loosen the Soil: Ensure the soil is loose and well-draining. Heavy or compacted soil can lead to root rot, so you may need to add sand or organic matter to improve drainage.

• Planting the Banana Trees
  • Spacing: Bananas need plenty of space to grow, so plant them about 8-12 feet apart. They can grow tall and spread out, so giving them space will ensure healthy growth.Planting: Dig a hole twice the size of the root ball and plant the banana tree at the same depth as it was in the pot. Water thoroughly after planting.
  • Mulch: Apply a layer of mulch around the base of the banana tree to retain moisture and control weeds.

• Planting Coffee Trees
  • Spacing: Coffee trees are smaller than banana plants, so plant them around 4-6 feet apart.Shading: Since coffee trees like partial shade, you can plant them under the canopy of banana trees. Alternatively, plant shade-loving plants or install a shade cloth to protect coffee trees from too much direct sunlight.
  • Planting: Dig a hole twice the size of the root ball and plant the coffee tree at the same depth as it was in the pot. Make sure to water the tree thoroughly after planting.

• Watering
  • Both banana and coffee plants require consistent moisture. Bananas need a lot of water but do not like sitting in waterlogged soil.
  • Water both plants deeply, ensuring the roots are moistened. Coffee plants generally need less water than bananas, so ensure the coffee plant soil doesn’t stay soggy. You can adjust watering schedules to suit each plant’s needs.

• Fertilizing
  • Bananas: Fertilize banana plants with a balanced fertilizer, or one high in potassium and nitrogen. Fertilize about once a month during the growing season (spring through summer).Coffee: Coffee plants need a more balanced, slow-release fertilizer that provides nitrogen, phosphorus, and potassium. Apply fertilizer in early spring and again in late summer.
  • Organic Matter: Adding organic matter like compost to both plants will help provide additional nutrients.

• Pruning and Maintenance
  • Bananas: Trim any dead or damaged leaves from the banana plants. Remove suckers to control the number of plants around the base. This will allow the main plant to grow stronger.
  • Coffee: Prune coffee plants to maintain a manageable shape and remove any dead or damaged branches. Coffee plants can be tall, so pruning will help improve air circulation and light penetration.

• Harvesting
  • Bananas: Bananas will take about 9-12 months to grow and ripen after planting. When the fruit is fully formed, and the banana fingers are plump and starting to turn yellow, you can harvest the bunch.
  • Coffee: Coffee plants take about 3-4 years to mature and begin producing fruit. Once the coffee cherries ripen (turning red), they can be harvested. You’ll need to pick the cherries by hand.

• Pest and Disease Management
  • Both plants are prone to pests like aphids, spider mites, and caterpillars. To manage pests, use organic pest control methods like neem oil or insecticidal soap.
  • Watch out for fungal diseases, particularly in areas with high humidity. Good airflow and proper spacing between plants can help prevent these issues.
• Long-Term Care: Bananas: After harvesting, you can cut down the banana plant as it will no longer bear fruit, but the suckers will continue to grow and bear fruit. Replace the cut plant with a new sucker.
• Coffee: Coffee trees can produce for several years. They may need occasional pruning and care to maintain healthy yields.

Here are five common challenges and how to overcome them when growing bananas and coffee together:

1. Shade vs. Sunlight.

Challenge: Bananas need full sun, but coffee thrives in partial shade.

Solution: Plant bananas in sunnier spots and position coffee trees under the banana plants or use shade cloth to protect them.

2. Watering Needs.

Challenge: Bananas need a lot of water, while coffee plants prefer slightly drier conditions.

Solution: Water deeply but be mindful of drainage. Ensure coffee areas stay slightly drier and banana areas stay moist.

3. Nutrient Competition.

Challenge: Both plants are nutrient-hungry and may compete for soil nutrients.

Solution: Use organic matter and compost to enrich the soil, and fertilize each plant with tailored blends.

4. Pests and Diseases.

Challenge: Both plants are prone to pests and fungal diseases.

Solution: Use organic pest control (like neem oil) and maintain good spacing and airflow to reduce fungal risks.

5. Space Limitations.

Challenge: Bananas need a lot of space to spread, which can overshadow coffee plants.

Solution: Space banana plants well apart and regularly prune them to prevent overcrowding and give coffee trees enough room.

Case study.

In Northern Uganda, Kitugm district specifically, KAWACOM Uganda Limited in partnership with USAID and proper Africa under the “Uganda Smallholder Livelihoods Initiative” actively involves and educates local farmers on the practice and benefits of CBI. They have gone ahead to set up over 40 acres of CBI demonstration fields. They hope to revert the climate change crisis and improve the smallholder farmers’ livelihoods reported by the senior agronomist Mr. Okema Danniel.  

In conclusion.

Coffee-banana intercropping is not. just a smart farming technique, it’s a game changer for yields, sustainability, and profitability by leveraging the natural synergy between these two crops, farmers can improve soil health, optimize land use, and create a more resilient agricultural system improving household gender dynamics. It also has environmental benefits for soil and water conservation, supporting sustainable agricultural production. As more farmers adopt this approach the future of coffee production looks not only more productive but also more sustainable whether you are a smallholder farmer or managing a large plantation, integrating bananas and coffee could be the key to maximizing both your harvest and your profits.
