The most important constraints for bean production in Peru are lack of breeding programs, inadequate management practices, lack of integrated pest management, and low production of improved seed. Therefore, the Instituto Nacional de Investigaciones y Promocion Agraria Grain Legume Program has pro...

Los principales factores limitantes de la produccion de frijol en Peru son falta de mejoramiento agronomico, practicas inadecuadas de manejo, carencia de un manejo integrado de plagas y escasa produccion de semilla mejorada. Por lo tanto, el Programa de Leguminosas de Grano del Instituto Nacional...

Results of 2 on-farm trials carried out in Peru during 1986 are presented in table form. In 1 of the trials, drought-tolerant bean var. were evaluated with 1 and 2 irrigation treatments. In the other trial, potentially rust- tolerant var. were evaluated at 2 plant densities. For drought condition...

Se presentan los resultados en forma de tabla de 2 ensayos realizados en Peru durante 1986. En un ensayo se evaluaron var. de frijol tolerantes a la sequia con 1 y 2 riegos. En el otro se evaluaron var. potencialmente tolerantes a roya a 2 densidades de siembra. Para sequia las var. promisorias f...

In coastal Ancash, Peru, on-farm studies were conducted on fertilization (0-0-0 and 40-60-0 kg/ha NPK), density (90,000 and 120,000 plants/ha), and weed control (2 and 3 manual weedings, resp.) to determine their effect on yields of beans in monoculture. Significant differences among treatments w...

Se realizaron ensayos exploratorios de fertilizacion (0-0-0 y 40-60-0 de NPK), densidad (90,000 y 120,000 plantas/ha), y control de malezas (2 y 3 deshierbas manuales, resp.) en campos de agricultores en la costa de Ancash, Peru, para determinar su efecto en el rendimiento del frijol en monoculti...

The purpose of the ICA research project on agricultural systems in Colombia is to generate appropriate technology for the different conditions of the growers and the area as well as plan research and technology transfer. The methodology used is described. Currently, the project is being carried o...

El objetivo especifico del proyecto de investigacion en sistemas agricolas del Instituto Colombiano Agropecuario en Colombia es generar una oferta tecnologica apropiada para las diferentes condiciones de la region y de los productores, y planificar ademas la investigacion y transferencia de tecno...
