Three trials were carried out at CIAT-Palmira to quantify the effect of plot edges and useful plot size in beans. In the 1st trial (sown in Oct. 1977), the competition effect of 36 climbing bean var. associated with maize ICA H-210 in adjacent plots and the effect of the alleys on plot edges were...

On-farm research activities in 1986 continued in the areas of training, network establishment, methodology adaptation, technology development on-farm, and technology adaptation to specific areas. One early result is a better understanding of the variability in the adaptation of the newly adopted ...

Las actividades de investigacion en fincas en 1986 continuaron en las areas de capacitacion, establecimiento de redes, adaptacion de metodologias, desarrollo de tecnologias a nivel de finca y adaptacion de tecnologias a areas especificas.

The methodology for on-farm research in Huila, Colombia, is summarized. Through this research, the technology generated at the exptl. station is evaluated, its technical feasibility is validated, and the local adaptable technology is included so technical recommendations be appropriate for farmer...

Se resume la metodologia seguida en el proceso de investigacion a nivel de finca por los agricultores en la zona sur del Huila, Colombia. Mediante esta investigacion se evalua la tecnologia generada en la estacion exptl., se valida su viabilidad tecnica y se incluye la tecnologia local adaptable ...

The most important characteristics of bean production systems in Aranzazu and Salamina (Caldas, Colombia) are summarized. Information collected in a survey detected the main constraints for bean cultivation in the area such as erosion, diseases, low density population, low-P and acid soils, and d...

Se resumen las caracteristicas importantes de los sistemas de produccion de frijol en Aranzazu y Salamina (Caldas, Colombia). Con base en la informacion recogida en una encuesta exploratoria, se detectaron los principales limitantes del cultivo del frijol en la zona como son erosion, enfermedades...

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...
