Pyrethrum thrives well in Kenya’s highlands because of the cool climate. You can easily reap huge profits from such a venture with proper farming practices. So, as the world shifts towards organic farming, the burning question arises, “What is the best pyrethrum yield per acre in Kenya?”

Pyrethrum growing in Kenya has fluctuated in the past few years, but it has been estimated to produce around 500 metric tons annually. Achieving the highest yield of pyrethrum requires cool temperatures and high rainfall. If you are considering growing pyrethrum in Kenya, it is essential to understand the yield per acre.
What is the highest pyrethrum yield per acre in Kenya?
According to Kilimo News, the highest pyrethrum yield per acre in Kenya is 200 Kilograms, which translates to an income of Ksh. 40,000. However, profitability depends on market access, pyrethrin content and production costs.
Pyrethrum growing areas in Kenya
Pyrethrum is predominantly grown in Kenya’s highlands, especially Nakuru, Nyandarua and West Pokot. These areas are characterised by altitudes ranging from 1,500 to 2,900 metres above sea level, providing optimal conditions for pyrethrum cultivation.
The rainfall in these regions is well-distributed, ranging from 800 to 1200 mm annually. Other pyrethrum growing areas in Kenya are highlighted below.
- Uasin Gishu
- Kericho
- Kisii
- Kiambu
- Narok
- Nyamira
- Nyeri
- Baringo
How long does pyrethrum take to mature?

Pyrethrum typically takes 10 to 18 days to mature and ready for harvest. Afterwards, the grass mulch should be removed gradually to allow the tender seedlings to harden. Note that pyrethrum plants should be cut back once a year towards the end of the dry season.
What is the best fertiliser for pyrethrum?
Choosing the best fertiliser for pyrethrum is essential to do a proper soil analysis. Consequently, farmers are advised to apply Triple superphosphate (T.S.P.) in each planting hole at 50–60 kg/acre (approximately 1 teaspoon/hole).
Additionally, you can apply Farmyard Manure (F.Y.M.) at 4 tonnes per acre (approximately one handful per hole). Note that F.Y.M. should be used 3 months before planting of the crop.
What are the main pests and diseases affecting pyrethrum crops?
Common pests that affect pyrethrum include flower and onion thrips, green peach aphids, leaf miners, and red spider mites. Diseases such as root rot, leaf blight, and powdery mildew can also affect pyrethrum.
Scrolling your fields twice weekly is crucial to removing infested crop residues. Spraying chemicals such as Deltamethrin or Lambda-cyhalothrin is also an adequate remedy.
What is the withholding period for pyrethrum?
The withholding period for pyrethrum only lasts for a day. This is the perfect time between applying the insecticide and harvesting the crop. Pyrethrum degrades quickly in UV light and, therefore, needs only a few minutes to kill all the insects.
What soil conditions are ideal for pyrethrum farming?
Pyrethrum thrives in well-drained loam soils with a pH range of 5.5 to 6.5. The soil should be rich in phosphorous, calcium and magnesium. In addition, it should have adequate moisture retention and proper organic matter. Farmers with acidic soils should have sufficient phosphate fertilisers, gypsum or lime.
Is pyrethrum a cash crop?
Yes, pyrethrum is one of the best cash crops in Kenya. You can sell the flowers to processing companies that extract pyrethrin, useful in producing natural insecticides and other products. It provides a steady source of income for farmers, especially in the highlands of Kenya.
Is pyrethrum farming profitable in Kenya?
Yes, pyrethrum farming can be profitable in Kenya, especially with the growing demand for natural insecticides. Farmers who follow best agricultural practices, including proper crop management and timely harvesting, can benefit from the high market prices.
