Onion Farming in Kenya: Onion Profit per Acre

Onion farming in Kenya is a highly profitable agribusiness, especially when the right onion varieties and farming practices are adopted. With growing demand, both locally and internationally, farmers are increasingly turning to this crop to generate income. In this article, we delve into the onion profit per acre, including costs, agronomist services, drip irrigation, and a detailed look at the characteristics of various onion varieties suited for Kenyan conditions.

Why Onion Farming in Kenya is Profitable

Onion farming in Kenya continues to be a profitable venture due to the increasing demand for onions. Regions such as Kajiado, Makueni, Kirinyaga, and Meru provide excellent growing conditions. The high demand for onions both in local markets and for export ensures a steady income for farmers. By integrating best practices such as drip irrigation and consulting agronomists, farmers can improve their yields and maximize their profits.

Cost of Onion Farming per Acre

Before calculating potential profits, it is essential to break down the typical costs associated with onion farming:

1. Land Preparation: Ksh 10,000 - Ksh 15,000
2. Seedlings: Ksh 25,000 - Ksh 35,000 (variety-dependent)
3. Fertilizers and Manure: Ksh 10,000 - Ksh 15,000
4. Pesticides and Fungicides: Ksh 5,000 - Ksh 8,000
5. Labor: Ksh 15,000 - Ksh 20,000
6. Irrigation: Ksh 10,000 - Ksh 15,000
7. Drip Irrigation Setup: Ksh 70,000 - Ksh 100,000
8. Agronomist Services: Ksh 20,000 - Ksh 30,000 (for 3 to 5 visits per season)

Total Cost Estimate

The total cost of onion farming per acre in Kenya, with drip irrigation and agronomist consultations, is estimated to be between Ksh 150,000 and Ksh 180,000.

Yield per Acre in Onion Farming

Depending on the onion variety, soil type, and farming practices, an acre of onion can yield 7 to 10 tonnes. Market prices for onions range between Ksh 50 and Ksh 100 per kilogram. Using an average price of Ksh 70 per kilogram, the potential revenue per acre is:

• 7 tonnes (7,000 kg) x Ksh 70 = Ksh 490,000
• 10 tonnes (10,000 kg) x Ksh 70 = Ksh 700,000

Onion Farming Profit per Acre

The profit is calculated by subtracting the total costs from the expected revenue:

• For a yield of 7 tonnes: Ksh 490,000 (Revenue) - Ksh 165,000 (Cost) = Ksh 325,000 Profit
• For a yield of 10 tonnes: Ksh 700,000 (Revenue) - Ksh 165,000 (Cost) = Ksh 535,000 Profit
