Best Maize Seeds For Farmers Planting this Long Rains

As the March planting season—popularly known as the “Long Rains”—approaches, the key to a bumper harvest lies in matching the right maize variety to your specific ecological zone. Whether you are in the high-potential “grain basket” of the Rift Valley or the drier lowlands, 2026 offers a range of high-yielding, disease-resistant seeds.

Here is a comprehensive guide to the best maize varieties to plant this March.

1. High-Altitude Regions (The Grain Basket)

Counties: Trans Nzoia, Uasin Gishu, Nandi, Kericho, Nakuru, and the Mt. Elgon slopes. In these areas, rainfall is high and the growing season is long (6–9 months). You need late-maturing varieties that can capitalize on this extended period to produce massive cobs.

2. Medium-Altitude & Transitional Zones

Counties: Kakamega, Bungoma, Murang’a, Kirinyaga, Embu, and parts of Meru. These regions have a bimodal rainfall pattern, meaning you need varieties that mature in 4–5 months to allow for a second crop later in the year.

• SC Duma 43 (Seed Co): A farmer favorite for 2026. It is incredibly fast (3 months) and highly tolerant to Maize Streak Virus. | H513 & H516 (Kenya Seed): Reliable standards for the “coffee belt.” They offer great husk cover, preventing cob rot.

• WH 402/505 (Western Seed): Specifically bred for the Western and Lake Basin regions; has slight tolerance to Maize Lethal Necrosis (MLN).

• DK 8031 (Dekalb): Famous for its “stay green” characteristic, allowing the plant to keep filling the cob even if rains tail off early.

3. Dryland & Coastal Lowlands

Counties: Machakos, Makueni, Kitui, Taita Taveta, and the Coastal strip (Kilifi, Kwale). In these areas, heat tolerance and “drought escape” are the priorities. You need seeds that finish their cycle before the moisture disappears.

• DH04 (Kenya Seed): A short-season hybrid (90–120 days) that is bred to escape drought.

• SC Sungura 301: One of the fastest on the market, maturing in just 75–85 days.

• PH01 & PH04 (Pwani Hybrids): Tailored for the humidity of the Coast; they have excellent husk cover to protect against cob rot and pests.

• Katumani Composite: An affordable, open-pollinated variety (OPV) that is very hardy for marginal areas.

4. Pro-Tips for the 2026 March Season

Beware of the “Striga” Weed

If your farm in Western Kenya or the Lake Basin is prone to the purple-flowered Striga weed, look for Ua Kayongo or WH 303 (IR). These are IR (Imazapyr Resistant) seeds coated with a herbicide that kills the weed as soon as it tries to attach to the maize roots.

Soil Health First

Maize is a “heavy feeder.” For 2026, experts recommend:

• Soil Testing: Check your pH. If it’s below 5.5 (common in Meru/Embu), apply agricultural lime at a rate of 500kg per acre.

• Basal Fertilizer: Use DAP or NPK (23:23:0) at planting to ensure strong root development.

Spacing Strategy

• Standard: $75\text{ cm}\times 25\text{ cm}$ (one seed per hole).

• High Fertility: Some modern hybrids like DK 90-89 can be planted more densely to maximize yield if you have the fertilizer to support them.
