POTATO GROWING IN KENYA
The most favourable climatic conditions are found in areas with a yearly rainfall of between 850 mm and 1200 mm, at altitudes between 1 500 m and 2 800 m above sea level. These areas are situated mainly in the Central, Rift Valley and Eastern provinces of Kenya.
Most of the potato crop is currently grown on a subsistence basis and relatively small amounts are sold in the urban and village markets. Per capita consumption is estimated to be 10 to 15 kg, compared with 100 kg in Western Europe and 150–200 kg in Eastern Europe per annum (Robinson, 1970). The average yield achieved by the small-scale farmer is approximately 6 to 7 tons per hectare. Large-scale farmers generally achieve higher yields, approximately 10 to 14 tons per hectare. Efficient husbandry and the use of improved planting material could increase average yields to 16–20 tons per hectare since yields of up to 40 tons per hectare have already been achieved (Ann. Report, Kenya, 1966).
