How profitable is sukuma wiki farming
The costs on this analysis are the upper-side. It is because we propose a strict adherence to crop management practices like crop nutrition, weed, disease and pest control. Other assumptions for the analysis are:
- The analysis is for open-field farming, which is rainfall reliant and differs from irrigation and greenhouse kales farming.
- The costs and prices are the average in Sukuma wiki market in kale farming regions like Nyandarua, Kiambu, and Kirinyaga counties.
- The constant kales buying price is KES 14 per kilogram (KES 700 per 50 kg bag).
Total yields and sales revenues
Given the above yield potential of 15,000 kg per acre, you can ear total revenue of KES 210,000 after selling your Sukuma wiki. a five acre farmer will earn KES 1,050,000.
The market prices for kales are highly volatile and affected by seasonality. Marketing is informal without use of weights and measures. Farmers sell bundles of kales at varying prices (KES 5- 20) based on prevailing market prices. we have assumed a price of KES 14 as a negotiated contract price standard in the harvesting period.
Costs of Kale production in Kenya
The cost of kale farming in Kenya, for one acre of land is KES 111,900 according to this post. These costs include costs for seeds, seedlings, soil and water testing, land preparation, fertilizers, pesticides and labor. The post will give you a detailed breakdown of these costs as follows.
Best kale seed varieties in Kenya
The cost of getting quality healthy kale seedlings for an acre is around Ksh 6800. These will include buying seeds and raising a nursery.
The best sukuma wiki varieties in Kenya are the hybrid or F1s. They have higher yields, short maturity period and longer harvesting period before they can flower. They include Mfalme F1 and Malkia F1 varities. Others like Kinale and Tosha varities are improved local varieties that has high yields per acre and can withstand common kale pests and diseases. Other popular kale varieties in Kenya are;
- Thousand-headed variety
- Collards Southern Georgia
- Ethiopian Kale (Kanzira)
- Marrow Stem
This analyis uses the Thousand headed kale variety. It has a long harvesting period of 2-3 months. A yield of 15 tons (15,000kg) per acre. The seed is resistant to some pests and diseases, good tolerance to heat and grows fast, strong and uniform with succulent leaves. You will need 125 grams/acre of Kale seeds. Buy quality certified seeds from an accredited agrovet or a seed company .
Sukuma wiki nursery bed
Establish a hygienic seed bed in the open field, a propagation tunnel or buy seeding trays for healthy seedlings. Thin excess seedlings and weed the bed to keep seedlings healthy. Besides, water them once or twice per day till they are ready to transplant.
Plant your Sukuma wiki seedlings when they have four or five leaves. Depending on how you raise the nursery, they are ready to transplant in 4-6 weeks after you sow your seeds In our estimates of the above activities (weeding, pest and disease control labour) you will spend KES 6,800 to get ready seedlings.
Highest kales yield are in well-drained fertile soils that has high organic matter. The optimal soil acidity is a value of pH range of 5.5 to 7.0. The best altitude is 800 to 2200 meters above sea level. The require ample rainfall of 750 mm and may need irrigation from time to time
To determine your soil and water suitability for growing kales. Do the basic soil and water analysis tests. For these, you will incur around KES 6,000 given current market costs.
The main site for your kales should have a fine tilth with soils at least 15 cm deep to promote better and faster and firm root development.
- Plough the land early enough to expose pests and perennial weeds to direct sunlight.
- Harrow the field two to three weeks after ploughing. This will further break and dry the soils to avoid crumbling.
Digging and harrowing can be done manually or using a tractor. The cost of these are Ksh 8,000 and Ksh 9,600 as shown in the figure above.

- Apply 1 teaspoonful or 5 g per hole (50 kg/acre) The cost is KES 3500 per 50 kg bag.
- Top-dress kales with 20 g of CAN (40 kg/acre) when plant is 20 cm tall and 40 g of CAN per kale plant (80 kg/ acre) three weeks later. You will buy a 50 kg bag at KES. 3000
To boost leave growth and appearance you can opt to apply foliar feed and bio stimulants like Easygro starter (N:P:K 18:20:21+ TE) and the Easygro vegetative (N:P:K 27:10:16 +TE).

Marginal profit analysis
The final analysis is the calculate gross income, net profits and production costs per square meter. According to the results, one acre farmer will make a gross profit of KES 24 and a net profit of KES 19 per square meter.
