La yuca en el Ecuador: recomendaciones para el desarrollo y ejecución de un proyecto de producción, secamiento y comercialización
La Colorada, on the North Coast of Colombia, was chosen by CIAT to study new technology validation in cassava. Trials measured the productivity of improved cassava production technology under actual field conditions, defined factors limiting cassava yields that may have been overlooked in the des...
Agricultural research in developing countries has lacked relevance to farm-level production problems, especially appropriate technologies for small-scale or limited-resource farmers. Currently research institutions are directing their efforts towards these objectives. This paper is a preliminary ...

The role of economists in on-farm testing in agricultural research
The possibilities of underdeveloped countries to satisfy their needs for food and to improve the standard of Eving through cassava production are analyzed. The following aspects are studied: potential cassava production (current and potential situation), general research policies and areas (var. ...
The different methodological stages of cassava on-farm trials and their relationships regarding the objectives and functions of the Cassava Program at the Centro Internacional de Agricultura Tropical (CIAT) are outlined. Site selection, farm trial design and analysis, and some illustrative result...
