Abstract: The paper describes research results obtained in the development of improved cultural practices, such as time and method of planting, weed control, fertilization, intercropping and erosion control.Experiments have shown that cassava yields are seriously reduced if either low rainfall or low temperatures are limiting growth during the period of 3-5 months after planting; that planting vertically or inclined produces higher yields than planting horizontally, especially during periods of drought; that planting on ridges is better in the rainy season but planting on the flat is better in the dry season; that high and sustainable yields can be maintained either with the application of 5-10 t/ha of animal manure supplemented with 50-100 kg/ha of N and/or K 2 O as chemical fertilizers (depending on soil fertility characteristics), or by the application of chemical fertilizers alone with a ratio of N:P 2 O 5 :K 2 O of 2:1:2 or 2:1:3, but not by organic or green manures alone; that intercropping with peanut generally increases total income and protects the soil from erosion; and that fertilization, intercropping, contour ridging and contour hedgerows of grasses are simple but effective ways to reduce erosion.
