Systems of production of beans and cassava in Latin America with implications for research design
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 ...
