Challenges Facing Sweet Potato Farming In Kenya


Sweet potato farming in Kenya has witnessed significant growth in recent years, thanks to its high yield potential and market demand. However, like any agricultural venture, sweet potato farming faces various challenges that can hinder its sustainable growth. In this article, we will delve into the key challenges faced by sweet potato farmers in Kenya and explore potential solutions to overcome these obstacles.

1. Pests and Diseases

1.1. Sweet Potato Weevil

The sweet potato weevil (Cylas spp.) is a major pest that attacks sweet potato plants, causing extensive damage to both foliage and tubers. Infestations lead to reduced yields and low-quality harvests. Integrated pest management (IPM) practices, such as regular field inspections, the use of resistant varieties, and the application of biocontrol agents or insecticides, can help control the weevil population.

1.2. Viral Diseases

Sweet potatoes are susceptible to several viral diseases, including Sweet Potato Leaf Curl Virus (SPLCV) and Sweet Potato Chlorotic Stunt Virus (SPCSV). These diseases can result in stunted growth, leaf curling, and reduced tuber development. Implementing strict sanitation measures, using disease-free planting material, and adopting resistant varieties can aid in disease prevention and control.

2. Lack of Quality Planting Material

The availability of quality planting material is crucial for the success of sweet potato farming. However, many farmers face challenges in accessing disease-free and high-yielding sweet potato vines. To address this issue, initiatives such as establishing certified seed multiplication programs and training farmers in vine multiplication techniques can ensure a steady supply of quality planting material.

3. Climate Change and Erratic Weather Patterns

Climate change poses a significant threat to sweet potato farming in Kenya. Erratic weather patterns, including prolonged droughts or excessive rainfall, can negatively impact crop growth and yield. Farmers can adopt climate-smart agricultural practices, such as rainwater harvesting, mulching, and conservation agriculture, to mitigate the effects of climate change and ensure sustainable production.

4. Post-Harvest Losses and Storage Challenges

Post-harvest losses are a common challenge faced by sweet potato farmers in Kenya. Improper storage conditions can lead to rotting, spoilage, and reduced market value of harvested tubers. Investing in proper post-harvest management practices, including curing, sorting, and using appropriate storage facilities, can help minimize losses and preserve the quality of harvested sweet potatoes.

5. Limited Market Access and Value Addition

Accessing profitable markets for sweet potatoes can be a challenge for farmers. Limited market linkages and low-value addition opportunities often result in lower prices and reduced profitability. Strengthening farmer cooperatives, promoting market diversification, and exploring value addition options such as processing sweet potatoes into chips, flour, or purees can enhance market access and profitability.

6. Limited Technical Knowledge and Extension Services

Many sweet potato farmers in Kenya lack adequate technical knowledge and access to extension services. This limits their ability to adopt best practices, address crop management challenges, and maximize their yields. Government agencies, NGOs, and agricultural institutions can play a crucial role in providing training, capacity building programs, and extension services to empower farmers with the necessary knowledge and skills.


While sweet potato farming in Kenya holds immense potential, it also faces several challenges. From pests and diseases to market access limitations and climate change impacts, farmers encounter various obstacles on their path to sustainable growth. By implementing integrated pest management practices, improving access to quality planting material, adopting climate-smart agricultural techniques, enhancing post-harvest management, expanding market linkages, and providing adequate technical support, these challenges can be overcome. With concerted efforts and a proactive approach, the sweet potato farming sector in Kenya can thrive, contributing to food security and economic prosperity for farmers and the country as a whole.
