The best irrigation practices for cassava farming in Kenya.

Irrigation is an important aspect of cassava farming in regions with irregular rainfall or extended dry periods.

Here are some of the best irrigation practices for cassava farming in Kenya:

1. Drip Irrigation: Drip irrigation is a highly efficient method that delivers water directly to the root zone of the cassava plants. It minimizes water waste and ensures that moisture is provided where it is needed most.

1.  
2. Mulching: Applying mulch around cassava plants helps conserve soil moisture, reduce evaporation, and suppress weed growth. Organic mulches, such as straw or grass, are commonly used in cassava farming.

1.  
2. Soil Moisture Monitoring: Regularly monitor soil moisture levels to ensure that the cassava plants receive adequate water. This can be done using soil moisture sensors or by observing the soil’s appearance and feel.
3. Irrigation Scheduling: Develop a well-defined irrigation schedule based on the growth stages of cassava. Critical stages such as planting, tuber initiation, and tuber bulking require careful attention to water requirements.
4. Furrow Irrigation: Furrow irrigation involves directing water between rows of cassava plants. It is a traditional and simple method, but care should be taken to avoid waterlogging and to ensure even distribution.

1.  
2. Efficient Water Use: Implement water-saving techniques such as controlled irrigation to avoid overwatering. Properly calibrated irrigation systems and efficient water use contribute to resource conservation.
3. Avoid Waterlogging: Cassava is susceptible to waterlogging, which can lead to root rot and reduced yields. Ensure proper drainage in the field and avoid over-irrigation that may lead to waterlogging.
4. Irrigate during Dry Spells: Supplemental irrigation is crucial during dry spells, especially during critical growth stages such as tuber initiation and bulking. Provide water to prevent water stress and ensure optimal tuber development.
5. Use Quality Irrigation Water: Ensure that the water used for irrigation is of good quality. Poor-quality water, high in salts or contaminants, can negatively impact cassava growth and development.
6. Combine Irrigation with Organic Matter Application: Incorporate organic matter into the soil along with irrigation. Organic matter improves soil structure, water retention, and nutrient availability, contributing to better cassava growth.
7. Irrigation Infrastructure Maintenance: Regularly maintain and inspect irrigation infrastructure, including pipes, pumps, and filters. Proper maintenance ensures the efficient functioning of the irrigation system.
8. Rainwater Harvesting: Consider rainwater harvesting as part of the irrigation strategy. Collecting and storing rainwater during the wet season can supplement irrigation during dry periods.
9. Educate farmers on irrigation practices: Provide training and extension services to farmers on best irrigation practices. Educating farmers on water management and efficient irrigation techniques enhances their ability to make informed decisions.
10. Integrated Water Management: Integrate water management practices into a holistic approach for sustainable farming. This includes combining irrigation with other water conservation measures, such as cover cropping and soil conservation.
11. Government Support and Extension Services: Encourage collaboration with government agricultural extension services to disseminate information on best irrigation practices and provide support to farmers.
