Item Guidelines for Production of Healthy Seed Potatoes In East And Central Africa(Kenya Agricultural Research Institute, 2006) Kabira, J. N.; Wakahiu, M.; Wagoire, W.; Gildemacher, P.; Lemaga, B.; Kenya Agricultural Research InstitutePotato is an important food and cash crop in East and Central Africa. It plays an important role in national food and nutrition security, poverty alleviation, and income generation and provides employment in production to consumption continuum. Potatoes mature in 3-4 months and can yield up to 40 t ha-1 • Most farmers obtain less than 10 t ha·1, mainly because of poor growing practices, low use of inputs and poor control of insect pests and diseases. Supply of good quality planting materials of improved varieties and timely availability can boost production of potatoes. Most farmers save and-plant seed from their own fields, or buy small tubers from neighbours or local markets. These practices allow diseases to build up resulting in low yields even when following recommended fertilisers and fungicides rates. Farmers should renew their seed stocks from clean sources such as research stations at least every 2-3 years, and then manage this seed carefully to minimise build-up of diseases and pests. This manual explains how to produce disease-free seed potatoes to support over one million ware potato growers in the region whose standard of cultivation requires to be upgraded.Item Long-Term and Short-Term Cassavas(July, 1944) Jameson, J. D.; Oates, C.; Muir, J. C.; Allnutt, T. B.; Nichols, R. F. W.; Department of Agriculture Kawanda, Kampala ,Uganda, Department of Agriculture Kenya, Department of Agriculture Tanganyika Territory, Department of Agriculture Zanzibar, Cassava Investigation of AmaniIt has been suggested here that correspondents to your journal might be able to throw light on a curious disparity in the practice of cassava cultivation between the various East African territories. In those parts of Uganda where cassava is an important reserve against famine it is the custom to plant up the greater part of the acreage with so-called "long-term" varieties. This description is perhaps not sufficiently definitive, but by it is meant varieties which stay in the ground for two or more years without appreciable deterioration to the tubers. The advantages of this course are presumablyItem Onion Cultivation on Kilimanjaro(1947) Swynnerton,R. J. M; TanganyikaVigorous growth must be maintained in the onions and this can be brought about by regular watering, weeding and the application of sulphate of ammonia. Onion beds should be flooded at regular intervals in dry spells during the rains and thereafter until harvest and the soil should never be allowed to dry out.
