Pyrethrum was introduced in Kenya from Europe in the 1928. Initially as a large scale crop. The success of pyrethrum cultivation in Kenya is attributed to good weather conditions. Currently, it is sparsely cultivated in the highlands of Kenya by small scale growers. Kenya used to produce about 70% of the world supply. Currently, there is a deficit in the supply to the world market demand.
The crop is favoured by cool temperature and high rainfall which occurs in the high-altitude areas ranging from 1700 – 2900m ASL. Fertile and well drained soils of moderate organic matter are also ideal for vigorous pyrethrum flower production. Recommended spacing is 60cm x 30 cm. Use TSP fertilizer at the rate of 60 – 80 kg/acre and manure at the rate of 4 tons per acre.
