 In: Revista Ceres (Brasil)Summary: En Vicosa y Coimbra (Minas Gerais, Brasil) se realizaron 2 expt. de cultivo asociado utilizando frijol var. Negrito 891 y var. de maiz de altura normal o corto. El frijol se sembro en la estacion lluviosa o en la seca. Las densidades de siembra del maiz fueron 20,000, 30,000, 40,000 y 50,000 plantas/ha. En la estacion lluviosa, el frijol se sembro en las hileras de maiz, mientras que en la estacion seca se sembraron 2 hileras de frijol entre las hileras de maiz. El maiz y el frijol tambien se sembraron en monocultivo para comparacion. La altura del maiz practicamente no tuvo efecto en los rendimientos de frijol y maiz. En la estacion lluviosa, la menor poblacion de maiz fue la mas benefica para el cultivo de frijol. En la estacion seca, sin embargo, las mayores densidades de siembra del maiz fueron las mejores. El cultivo asociado incremento efectivamente la produccion de alimentos/unidad de area. (RA-CIAT)Summary: In Vicosa and Coimbra (Minas Gerais, Brazil), 2 associated cropping expt. using bean var. Negrito 891 and maize var. of the normal or short type were carried out. The beans were either planted in the rainy or in the dry season. Plant densities of maize were 20,000, 30,000, 40,000, and 50,000 plants/ha. In the rainy season, beans were planted within the maize row, while in the dry season 2 rows of beans were planted between the maize rows. Maize and bean monocrops were also planted for comparison. Maize height had practically no effect on bean and maize yields. In the rainy season, the lowest maize population was the most beneficial to the bean crops. In the dry season, however, the higher plant densities of maize were the best. Associated cropping effectively increased food production/unit area. (AS)
