How to Sell Maize in Kenya: Getting the Best Price for Your Harvest
When to sell maize, where to sell it, how to store it to avoid losses, and how to negotiate better prices. A practical guide for Kenyan maize farmers.
Maize is Kenya's most important crop — but most farmers sell at the wrong time and lose a significant portion of their profit. This guide covers how to store maize properly, when to sell, where to get the best price, and how to use buyer demand to your advantage.
The Maize Price Cycle in Kenya
Understanding the market is the most important skill a maize farmer can have.
When prices are lowest: March–May (long rains harvest) and September–October (short rains harvest). This is when most farmers sell, which floods the market.
When prices are highest: January–February and July–August — the lean months before new harvest. Prices can be 30–60% higher than harvest time.
If you can store your maize and wait, you can significantly improve your return.
Proper Maize Storage to Avoid Losses
Poor storage kills profits. Weevils, mould, and moisture can destroy 30–50% of your stored grain if you're not careful.
Moisture Content is Critical
Maize must be 13.5% moisture or below before storage. Above 14%, mould grows. Check with a moisture metre (buy or borrow from your local agro-vet or cooperative).
Sun drying: Spread maize on a clean tarpaulin in bright sun for 2–3 days. Turn regularly. Don't dry on the ground — you'll pick up soil and moisture.
Storage Options
Metal silos: Best option for long-term storage. Hermetic (airtight) storage eliminates weevils without chemicals. PICS bags work the same way at lower cost.
PICS bags (Purdue Improved Crop Storage): Triple-layer hermetic bags. Stack maize in the bag, expel air, tie tightly. Weevils die within 4–6 weeks. Cost: KES 150–200 per bag. One bag holds 90kg.
Raised granary (traditional): Works for short-term storage if maize is very dry. Needs regular inspection for weevils.
Avoid: Storing maize in cotton or sisal bags — these allow moisture in. Don't store near chemicals.
Treating for Weevils
If not using hermetic storage, treat with approved grain protectant:
- Actellic Super Dust — most widely used, apply at 5g per 90kg bag
- Phostoxin (Aluminium Phosphide) — fumigation tablets for larger volumes. Requires care — toxic gas.
Apply treatment immediately after drying and before weevil infestation begins.
Where to Sell Maize in Kenya
National Cereals and Produce Board (NCPB)
The government buyer. Guaranteed minimum price (when operational). Advantages: reliable payment, clear grading. Disadvantages: long queues, may pay slowly, not always active in all counties.
Current NCPB price: Check with your local NCPB depot — prices are set seasonally.
Private Millers
Large millers (Unga Group, Pembe, Delmonte) buy directly from farmers or through aggregators. They pay well for clean, dry maize meeting their standards (13.5% moisture, sorted, no foreign matter).
How to access: Call their procurement departments or work through a certified aggregator.
Local Traders and Brokers
Buy at the farm gate or market. Convenient but usually the lowest price. Use them only if you need cash quickly.
Farmer Cooperatives
If you're a member, your cooperative can aggregate your grain with other members and access better prices through volume. Worth joining if there's an active one in your area.
Online Platforms — Agrisoko
Post your maize as a listing on Agrisoko to reach bulk buyers — millers, traders, and large buyers actively looking for maize. You set your price, they contact you.
How to Negotiate a Better Price
- Know the current market price before you sell. Check multiple buyers.
- Sell in bulk — buyers give better prices for larger volumes (10+ tonnes vs 1–2 bags).
- Have your maize tested — bring a moisture metre reading and a clean sample. This proves quality.
- Offer delivery flexibility — if you can deliver to the mill rather than farm gate, you may earn more.
- Join with neighbours — aggregate grain from 5–10 farmers to reach the minimum volumes millers want.
Maize Grading Standards
For premium prices, your maize should meet:
- Moisture: ≤13.5%
- Aflatoxin: Below 10 ppb (parts per billion) — millers test for this
- Foreign matter: Under 1%
- Broken grains: Under 3%
Aflatoxin is increasingly important. Avoid harvesting immature cobs, dry quickly after harvest, and don't store damaged maize. Aflatoxin-contaminated maize is rejected outright.
Value Addition: Maize Flour
If you have access to a posho mill, consider processing some of your maize into flour for local sale. Flour fetches 3–5× the grain price. Even small-scale processing (hiring a posho mill to grind your maize) can improve margins.
Key Takeaways
- Don't sell at harvest if you can store properly
- Use PICS bags or metal silos to preserve grain
- Dry to 13.5% moisture before storage
- Know the NCPB price as your floor
- Aggregate with neighbours for better buyer prices
- Post your maize on Agrisoko to find buyers directly
