 In: In: Congresso Brasileiro de Mandioca (2, 1981, Vitoria-ES). AnaisSummary: En el Centro Nacional de Pesquisa de Mandioca e Fruticultura en Cruz das Almas (Bahia, Brasil) se estudio el efecto de la rotacion de cultivos con leguminosas (mani cv. Maranhao) y gramineas (maiz cv. Dentado Composto) en la productividad de raices y de almidon de yuca cv. BGM-116, para determinar cuales rotaciones de cultivo contribuian a una mejor conservacion del suelo y al control de plagas y enfermedades. Se utilizo un diseno de bloques al azar con 11 tratamientos y 4 repeticiones. Los resultados obtenidos de expt. sucesivos llevados a cabo en el mismo sitio (previamente sembrado de Pennisetum purpureum durante 10 anos) a traves de varios anos, con y sin fertilizacion, demostraron que la rotacion de cultivos tenia un efecto marcado en la produccion de raices de yuca, principalmente cuando se realizaron las rotaciones con gramineas. Esto indico la existencia de varios desequilibrios en el suelo. La mayor produccion de yuca se obtuvo cuando se fertilizo el primer cultivo de yuca, seguido por cultivos de leguminosas o gramineas sin fertilizar o por periodos de barbecho, y luego yuca fertilizada. El contenido de almidon de yuca no vario entre tratamientos. (RA-CIAT)Summary: The effect of crop rotation with legumes (groundnut cv. Maranhao) and grasses (maize cv. Dentado Composto) on the root and starch productivity of cassava cv. BGM-116 was studied at the Centro Nacional de Pesquisa de Mandioca e Fruticultura in Cruz das Almas (Bahia, Brazil) to determine which crop rotations contributed to improved soil conservation and pest and disease control. A randomized block design was used with 11 treatments and 4 replications. Results obtained from successive expt. carried out at the same site (previously planted to Pennisetum purpureum for 10 yr) over several years, with or without fertilization, showed that crop rotation had a marked effect on cassava root production, mainly when rotations were carried out with grasses. This indicated the existence of several soil imbalances. Highest cassava production was obtained when the lst cassava crop was fertilized, followed by unfertilized legume or grass crops or by fallow, and then fertilized cassava. Cassava starch content did not differ among treatments. (AS-CIAT)
