A summary is presented of results of trials conducted as part of the collaborative agreement between the Instituto Colombiano Agropecuario and CIAT on bean research during 1981 in La Selva, Antioquia (Colombia). During germplasm evaluation, 112 promising materials were identified for their adapta...
Studies were conducted at CIAT to test a new methodology (1) to improve F3, yields through the use of a hierarchical exptl design (a 9 x 9 lattice with 3 replications, with lines grouped according to the design, without taking into accont the family of origin) and (2) to select beans in associati...

Seleccion en generaciones tempranas de frijoles volubles en asociacion con maiz
Maize and climbing beans as associated crops prevail in the highlands of L.A. in traditional systems with low populations and manual planting (in rows and pocket drilling). Two trials were establislied to compare the systems, testing bean densities from 4- 12 plants/m(2) and 3-12 plants/m(2), wit...
Anthropological work carried out by the PROFRIZA project in Cusco over 2 cropping seasons, between 1988-90, are reported. The status of bean cultivation in the region was assessed, as well as the experience acquired in seed production, small farmer management of farming activities, and the integr...

Nuevas tecnologias: Aceptabilidad y modificaciones por los agricultores en el Valle Sagrado
The improvement strategy of climbing bean in Cusco should take into account the importance of maize as a crop. In a recent study in 2 maize-growing communities of Valle Sagrado, 75 and 88 percent of the farmers considered beans as the main crop; however, only 57 and 22 percent of the maize-growin...

This paper details changes to the BEAM models, RRYIELD and RRECON, which are two of a series of bioeconomic models developed by the Bioeconomic Agroforestry Modelling (BEAM) project. The RRYIELD model deals with the biophysical components of a rubber-based agroforestry system. It focuses on the c...
