La produccion de yuca en Africa es aprox. de 34 millones de t (39 por ciento de la produccion mundial). La produccion de los paises africanos de habla francesa (incluyendo Madagascar y excluyendo a Zaire) es de 6,5 millones de t (un incremento del 40 por ciento en 20 anos, igual al crecimiento de la poblacion). Se hace una distincion entre los paises de la Zona Guinea (Costa de Marfil, Togo, Dahomey, Camerun), donde es un alimento principal para la mayor parte de la poblacion, y los paises de Sudan (Senegal, Mali, Niger, Alto Volta, Chad), consumidores de cereales. Se observa que la produccion se incremento mas vigorosamente en los paises sabaneros que en los humedos. En Madagascar, la cantidad de almidon procesado ha decrecido bruscamente (12.000 t en 1971 vs. 40.000 t en 1950); este es el unico pais donde se usa como alimento para animales, pero a pequena escala. La yuca se cultiva generalmente en predios familiares, manualmente y con el sistema de cultivo migratorio; su rendimiento promedio es de 5-12 t/ha. Los altos precios internos y las restricciones a la exportacion son los factores que limitan su produccion. Se pueden incrementar los rendimientos de 15-25 t/ha mediante practicas culturales conocidas y var. mejoradas. Se discute la investigacion que esta realizando el Institut de Recherches Agronomiques Tropicales et des Cultures Vivrieres. (CIAT) spa
Cassava production in Africa is ca. 34 million t (39 percent of world production); in French-speaking Africa (including Madagascar and excluding Zaire), it is 6.5 million t (an increase of 40 percent in 20 yr, the same as the gpowth in population). If distinguishing between the Guinean zone (Ivory Coast, Togo, Dahomey, Cameroon), where cassava is a staple food, and the Sudanian zone (Senegal, Mali, Niger, Upper Volta, Tchad), where the people mainly consume cereals, it can be seen that production increased more vigorously in the savanna countries than in the humid ones. In Madagascar the amount of starch processed is decreasing sharply (12,000 t in 1971 vs. 40,000 t in 1950); it is the only country where cassava is used for animal feed, but on a small scale. Cassava is generally cultivated manually on family farms in a shifting cultivation system; yields av 5-12 t/ha. Factors limiting production are economic: limited foreign markets and rather high domestic prices. Increased productivity (from 15 to 25 t/ha) can be obtained easily using known cultural practices and improved var. The research being done in the different countries by the Institut de Recherches Agronomiques Tropicales et des Cultures Vivrieres is discussed. (CIAT) eng
