World cassava production and yield trends 1960-1968 = Tendencias de la producción y rendimiento de la yuca
Basic data were compiled in table form on cassava production, and an analysis was made of past trends of the relationship cassava production/population for each of the cassava-producing countries from 1960-68. The tendency of per capita production was estimated by simple linear regression. During the period studied, the area planted to cassava increased an av of 200,000 ha/yr; the largest increases were in Africa and S.A. (480 and 124,000 ha, respectively). World production increased 2 million t/yr, but yields did not change. Per capita production increased 7.5 kg/yr in S.A. but decreased for the rest of the world. About 40 percent of world production comes from S.A. (25 percent of the area planted) and 36 percent from Africa (approx 50 percent of the world area). Brazil produces approx 1/3 of the total world production and 85 percent of S.A. production. Av world yield is estimated at 8.69 t/ha; Malawi and Brazil have the highest yields (23 and 20 t/ha, respectively). It is concluded that population growth exceeds the increase in cassava production since there is a decreasing trend in per capita production. (CIAT)

(CIAT) Se recopilo informacion basica en forma de cuadros sobre la produccion de yuca en el mundo y se analizaron las tendencias pasadas de la relacion entre produccion y poblacion para cada uno de los paises productores durante el periodo 1960-68. La tendencia en la produccion per capita se estimo mediante un regresion lineal simple. Durante el periodo estudiado el area sembrada aumento en un promedio de 200.000 ha/ano; los mayores aumentos se observaron en Africa y America del sur (480 y 124 mil ha/ano). La produccion mundial aumento en 2 millones de ton metricas/ano, pero el rendimiento no vario. La produccion per capita aumento en 7,5 kg/ano en Sur America, pero disminuyo en el resto del mundo. El 40 por ciento de la produccion mundial proviene de Sur America (25 por ciento del area mundial sembrada) y Africa, 36 por ciento (aprox. 50 por ciento del area mundial sembrada). Brasil produce aprox. 1/3 de la produccion mundial total y 85 por ciento de la produccion de Sur America. El rendimiento promedio mundial se estima en 8,69 ton/ha, pero Malawi y Brasil presentan los mayores rendimientos (23 y 20 ton/ha, respectivamente). Se concluyo que el crecimiento de la poblacion excede al aumento en la produccion de yuca ya que existe una tendencia descendente en la produccion per capita.
