Sorghum is a vital cereal crop in Kenya, especially valued for its drought tolerance and adaptability to arid and semi-arid lands (ASALs). It serves as an important food security crop for many smallholder farmers living in regions prone to erratic rainfall and harsh climatic conditions.

Sorghum is not only used for food but also for fodder, brewing, and industrial purposes. This article provides a detailed guide on sorghum farming in Kenya, covering everything from regional planting calendars, land preparation, variety selection, crop management practices, to harvesting and post-harvest handling.

You will learn about the best times to plant sorghum according to Kenya’s climatic zones, how to prepare your land for optimal crop growth, and which sorghum varieties perform well in different regions.

The article also explains key agronomic practices such as sowing methods, fertilizer application, weed and pest control, and irrigation considerations. Understanding these factors helps farmers improve yields, manage risks, and maximize profitability.

Sorghum is well suited for Kenya’s dry areas such as Turkana, Kitui, Makueni, and parts of Eastern and Rift Valley regions, where other crops may fail due to drought. With growing interest in sorghum as a commercial crop, this guide also includes insights on market opportunities and value addition.

Whether you are a small-scale farmer looking to diversify or a commercial grower aiming to expand your cereal portfolio, this article will provide the practical knowledge needed to succeed with sorghum farming in Kenya.

1. Sorghum Planting Seasons and Regional Adaptation.

Sorghum’s planting calendar in Kenya is largely determined by rainfall patterns and regional agroecological conditions. The crop is predominantly grown in arid and semi-arid lands that receive between 300 and 800 mm of annual rainfall.

In these areas, the best planting time usually coincides with the start of the long rains from March to May. Some farmers also plant sorghum during the short rains between October and December, especially in parts of Eastern and Rift Valley regions where rainfall is bimodal.

In northern Kenya and the dry parts of Eastern Province such as Kitui, Makueni, and Machakos, sorghum planting begins with the onset of the long rains. These areas benefit from the crop’s drought tolerance and ability to grow on poor soils where maize may fail. In parts of Rift Valley and Western Kenya, sorghum is planted mostly during the long rains and is harvested before the dry season sets in.

Timing planting to align with reliable rainfall is crucial since sorghum requires sufficient moisture during germination and early growth stages. Planting too early, before rains are established, may lead to poor seed emergence.

Conversely, late planting reduces the growing period and can decrease yields. Farmers in marginal areas often use rainfall forecasts and traditional knowledge to decide when to plant. By understanding the regional planting calendar, farmers can optimize water use and improve crop success.

2. Land Preparation and Planting Techniques.

Good land preparation is essential for successful sorghum cultivation. Land should be cleared of weeds and debris before ploughing or digging. Depending on the size of the farm and available resources, farmers can use ox-drawn ploughs, tractors, or hand hoes. Ploughing breaks up the soil, improves aeration, and helps control weeds.

The land should be prepared well in advance of planting to allow the soil to settle and retain moisture. Ideally, soil should be tilled twice, first to break up compacted layers and second to create a fine seedbed. In arid areas, conservation farming practices such as minimum tillage and mulching are recommended to conserve soil moisture and reduce erosion.

Planting depth for sorghum is generally 3 to 5 cm. Seeds should be sown in rows spaced 75 to 90 cm apart, with plants spaced 20 to 30 cm within rows depending on variety and fertility. This spacing ensures adequate sunlight penetration and air circulation. Sorghum can be planted by broadcasting, drilling, or dibbling. Drilling ensures uniform seed placement and reduces seed wastage.

Seed treatment with fungicides or insecticides before planting is advised to protect against seed-borne diseases and early pests. Using certified seeds improves germination rates and crop vigor. Proper land preparation combined with correct planting techniques lays the foundation for healthy sorghum crops and better yields.

3. Sorghum Varieties and Their Suitability.

Kenya has a range of sorghum varieties developed for different ecological zones and farming systems. The main types include grain sorghum for food, sweet sorghum for syrup and biofuel, and fodder sorghum for livestock feed. Grain sorghum is the most commonly grown type for human consumption.

Early maturing varieties like Seredo and Seredo II mature within 90 to 110 days and are well suited to low rainfall areas. These varieties are drought resistant and can complete their growth cycle before the dry season intensifies. Medium and late maturing varieties such as Seredo III and Gadam mature in 120 to 140 days and are preferred in regions with reliable rainfall or irrigation.

Hybrid varieties released by KALRO and research institutions combine higher yields with pest and disease resistance. They also include improved tolerance to Striga weed, a major constraint in sorghum farming. Choosing the right variety depends on factors such as rainfall, soil fertility, end-use preference, and market demand.

Farmers are encouraged to obtain certified seed from reputable sources to ensure genetic purity and vigor. Using local landraces may be suitable for traditional dishes but often yield less. Selecting the appropriate variety aligned with the planting calendar and regional conditions significantly boosts productivity.

4. Crop Management: Fertilization, Weed, Pest, and Disease Control.

Effective crop management is critical for maximizing sorghum yields. Fertilizer application should be based on soil fertility status. Generally, sorghum responds well to nitrogen and phosphorus fertilizers. Basal application of Di-ammonium phosphate (DAP) or Triple Superphosphate (TSP) at planting helps establish strong root systems. Top-dressing with nitrogen fertilizer such as CAN or urea 3 to 5 weeks after emergence supports vigorous growth.

Weed control is essential as weeds compete for nutrients, water, and light. Mechanical weeding through hand hoeing is common, especially during the first 4 to 6 weeks after planting. Herbicides may also be used but require careful application to avoid crop damage.

Sorghum faces several pests including stem borers, aphids, and birds. Integrated pest management (IPM) practices combining cultural, biological, and chemical controls are recommended. Crop rotation and intercropping reduce pest buildup. Early planting can help escape peak pest periods. Birds can be deterred using scarecrows and netting.

Diseases such as anthracnose, grain mold, and leaf blight affect sorghum yields. Resistant varieties, timely field sanitation, and proper spacing help manage disease pressure. Monitoring fields regularly for signs of pests and diseases enables early intervention, reducing crop losses.

5. Harvesting, Post-Harvest Handling, and Marketing.

Sorghum is typically ready for harvest when the grains harden and the moisture content falls below 14 percent. For most varieties, this is between 3 to 5 months after planting depending on maturity period and growing conditions. Harvesting at the right time reduces grain losses and maintains quality.

Harvesting is usually done manually by cutting the mature panicles with knives or sickles. After cutting, sorghum stalks are left to dry in the field for a few days to reduce grain moisture. Threshing separates the grains from the stalks and can be done by beating or using mechanical threshers.

Proper drying of sorghum grains before storage is critical to prevent mold growth and aflatoxin contamination. Grains should be dried to a moisture content of about 12 to 14 percent. Farmers are advised to store sorghum in clean, dry, and well-ventilated containers or granaries. Hermetic bags and metal silos are increasingly used to improve storage conditions and reduce losses from pests and moisture.

Marketing sorghum has gained momentum due to rising demand for sorghum-based foods and beverages. Farmers can sell grains to local millers, breweries, or through cooperative societies. Value addition such as flour milling, brewing, and animal feed production offers additional income streams. Proper post-harvest handling ensures better prices and market competitiveness.
