The trials conducted by CIATs Bean Economics Program in southern Huila (Colombia) have indicated that in this region monoculture bean yields can be increased 1-1.5 t/ha through improved agronomic practices. This paper is an ex ante analysis of the effect of this new technology on farmers` income,...

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 ...

Autor: Alvarado, L Sanders, J.H.

In 1976 expt. were conducted on var. trials, fertilization, insecticides, and herbicides in order to identify new technology that could be introduced into small- and intermediate-scale bean production in Honduras. Factors of a complete technological package were also discarded to identify the mos...

L.A. bean production has stagnated due to the continuing yield declines. Production has been maintained by area expansion in some countries (Brazil); in others, it has increased due to a strong export demand from European and Venezuelan markets. High population and per capita income growth kept d...

La produccion del frijol en America Latina se ha estancado con las continuas disminuciones en los rendimientos. En algunos paises (Brasil), la produccion se ha mantenido mediante la expansion del area de cultivo; en otros, ha aumentado debido a una fuerte demanda de exportacion de los mercados eu...
