This article explores why bean farming is an easy and profitable venture, provides examples from various East African countries, and highlights the potential for export.

Why Bean Farming is Easy and Profitable

1. Low Initial Costs and Market Competition
   Bean farming requires a relatively low initial investment compared to other crops. The costs for seeds, fertilizers, and labor are minimal, making it accessible even for small-scale farmers. Moreover, the market for beans is not overly saturated, providing a favorable environment for new entrants. The startup costs mainly involve land preparation, seed purchase, and basic farm inputs. In Kenya, for instance, the average cost of cultivating an acre of beans ranges from KES 10,000 to 15,000 (about USD 100 to 150). This includes costs for land preparation, seeds, and weeding. Similarly, in Tanzania, the cost of cultivating beans on an acre is approximately TZS 200,000 to 300,000 (USD 85 to 130), making it a relatively affordable venture for many farmers.
2. High Yield Potential per Acre
   With good farming practices, an acre of beans can yield significant amounts. For example, in Uganda, an acre of beans can produce between 10 to 15 bags (each bag weighing 90 kg), depending on the variety and soil fertility. This translates to about 900 to 1,350 kg per acre. In Tanzania, farmers report yields of 8 to 12 bags per acre for yellow beans, though this can increase with improved varieties and farming techniques. In Rwanda, the yield can reach up to 20 bags per hectare due to the country’s favorable climate and use of improved farming techniques. The potential for high yields per acre makes bean farming a reliable source of income for farmers in these regions.
3. Multiple Harvests Per Year
   One of the significant advantages of bean farming is the ability to harvest multiple times a year, especially in areas where irrigation is available. In Kenya’s Rift Valley region, for instance, farmers can grow beans up to three times a year due to the availability of irrigation and favorable climatic conditions. This means that even with just one acre of land, a farmer can secure a steady and substantial income every four months. In Uganda, particularly in the highland areas of Kabale and Kisoro, farmers can also achieve up to three harvests per year, maximizing their profits and ensuring food security. The potential for multiple harvests provides financial stability and growth opportunities for farmers.
4. Growing Demand and Market Opportunities
   Beans are a staple food in East Africa, consumed by millions of households daily. This high demand provides a ready market for farmers. In addition to local consumption, there is also a growing export market for beans. For instance, Kenya exports beans to regional markets such as Uganda, Tanzania, and Rwanda and international markets like Europe and the Middle East. In 2023, Kenya exported approximately 100,000 metric tons of beans, generating over USD 60 million in revenue. Uganda also exports beans to regional markets, contributing significantly to the country’s agricultural exports. The growing demand for beans in both local and export markets makes bean farming a profitable venture.

Bean Farming Practices in East Africa

1. Planting Techniques for Beans

• Seed Selection and Planting Time
  Choosing the right type of seeds and planting them at the appropriate time is crucial for maximizing yields. In Tanzania, for example, the planting of beans is aligned with the rainy seasons to ensure sufficient water supply. The first planting season usually starts in March with the long rains, while the second season begins in October with the short rains. The harvesting period should coincide with drier conditions to prevent spoilage. Excess water stagnation and drought are harmful to beans, as they can cause diseases or lead to rotting or drying up of the plants.
• Varieties of Bean Seeds
  There are various types of beans that can be planted in East Africa, such as the Rojo, Mshindi, Pesa, SUA 90, and Canadian Wonder, which are improved varieties known for their high yields and resistance to diseases. In Uganda, the NABE series (NABE 4, NABE 14, NABE 15) are popular improved varieties developed by the National Agricultural Research Organization (NARO) for their high yield potential and resistance to pests and diseases. Farmers also have access to traditional seeds that are more resistant to certain pests and diseases. In Rwanda, the RAB (Rwanda Agriculture Board) has developed several improved varieties like RWV1129 and RWV3316, which are well-suited to the local conditions and have high yield potential.
• Planting Guidelines
  Proper spacing is essential for optimal bean growth. It is recommended to plant beans at a spacing of 50 cm between rows and 20 cm between plants. Two seeds should be planted in each hole at a depth of 3-6 cm. If planting one seed per hole, spacing can be reduced accordingly. A well-planted bean field should have between 150,000 to 200,000 plants per hectare for bush beans, and half that number for climbing beans. It’s important to note that 1 hectare is equivalent to 2.471 acres. This spacing allows for sufficient air circulation and sunlight penetration, reducing the risk of diseases and pests.

2. Pest and Disease Management

Effective pest and disease management is crucial for achieving high yields in bean farming. Common pests affecting beans in East Africa include aphids, bean flies, and cutworms, while diseases such as anthracnose, rust, and angular leaf spot are prevalent. Integrated Pest Management (IPM) practices, which combine cultural, biological, and chemical control methods, are recommended. For example, in Kenya, farmers use a combination of crop rotation, resistant varieties, and safe chemical pesticides to manage pests and diseases. In Rwanda, the government promotes the use of organic pesticides and biocontrol agents to minimize environmental impact and improve bean quality.

Case Studies from East Africa

1. Kenya: Success in Bean Farming in Rift Valley

The Rift Valley region of Kenya is renowned for its fertile soils and favorable climate, making it ideal for bean farming. Small-scale farmers in this region have successfully adopted improved bean varieties such as Nyota and KAT B1, which are resistant to common pests and diseases. A farmer in Nakuru County, for instance, reported an increase in yield from 8 bags per acre to 15 bags after switching to improved varieties and adopting proper spacing and timely planting techniques. Additionally, the farmer utilized organic manure and mulching to improve soil fertility and moisture retention. The profitability of bean farming in this region has attracted more farmers, contributing to improved livelihoods and food security.
