Online resources: Summary: Se hizo un estudio de las 4 regiones productoras de frijol mas importantes de Colombia (87 por ciento de la produccion nacional) de 1974-75. Se encontraron tanto de monocultivo sistemas altamente comerciales (11 por ciento - Valle) como pequenos sistemas de cultivos asociados (76 por ciento- Huila, Antioquia, Narino). El rendimiento promedio para ambos sistemas fue de 905 y 598 kg/ha, respectivamente. En el Valle, donde se cultiva el frijol negro principalmente para exportacion, las principales limitaciones son las lluvias excesivas durante la floracion y fructificacion, la roya, el anublo bacteriano, Empoasca sp. y la mancha angular de la hoja. Solamente la utilizacion de variedades resistentes a la roya hubiera incrementado los rendimientos a ca. USSummary: A survey was made of the 4 most important bean-growing regions in Colombia in 1974-75, representing 87 percent of national production. Both highly commercial monocropping systems (11 percent- Valle) and small associated cropping systems (76 percent -Huila, Antioquia, Narino) were found. Av yields for the 2 were 905 and 598 kg/ha, respectively. In the Valle, where black beans are grown mostly for export, the principal constraints are excessive rainfall during flowering and fruiting, rust, bacterial blight, Empoasca sp. and angular leaf spot. The use of rust-resistant var. alone would have increased yields ca. US
