Sanders, J.H.Álvarez Payan, C.[Evolución de la producción de fríjol en América Latina durante la última década]Evolución de la producción de fríjol en América Latina durante la última década

The trends and yield constraints in production systems of beans and cassava are analyzed; examples are given of the role of 3 types of information (macro stage, micro stage, and critical inference stage) in the design of research for beans and cassava at the Centro Internacional de Agricultura Tr...


Sanders, J.H.Lynam, John K.[Trends and yield constraints in the production systems of beans and cassava in Latin America with emphasis on research design implications]Trends and yield constraints in the production systems of beans and cassava in Latin America with emphasis on research design implications

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,...

Schwartz, Howard F.Sanders, J.H.[Plant diseases of dry beans (Phaseolus vulgaris L.) in Latin America and strategies for their control]Plant diseases of dry beans (Phaseolus vulgaris L.) in Latin America and strategies for their control

A methodology is presented on how to study bean production processes and its on-farm application in Colombia. The main objectives are to identify the factors limiting production and productivity, availability and use of resources, credit, technical assistance, markets, pest and weed distribution ...

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...

Autor: Sanders, J.H.

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...

Beans are attacked by a large no. of plant pathogens and insect pests, many of which can reduce yields drastically. Farmers with small land holdings usually have limited resources but produce most of the beans in L.A. Control strategies feasible for these growers may be restricted to those strate...

El frijol es atacado por un gran no. de organismos fitopatogenos y plagas, muchas de las cuales disminuyen los rendimientos significativamente. Los agricultores que poseen pequenas parcelas tienen generalmente ingresos muy limitados pero producen casi todo el frijol en America Latina. Las estrate...

On-farm research results of 3 yr evaluating new bean technology (var. and cultural practices) at Pitalito, Suaza, and Timana in southern Huila, Colombia, are presented. Clean seed, insecticides, increased plant density, fertilizers, and new var. for both monocropped and associated (maize) beans w...
