During 1981 the analysis of the potential adoption and impact of improved cassava production technology was continued at various levels and included: farm-level studies of the profitability of improved technology and constraints to adoption; analysis of costs of processing and marketing; and rese...
Durante 1981 se continuo el analisis de la adopcion potencial y el impacto de la tecnologia mejorada en la produccion de yuca en varios niveles se incluyo: estudios sobre la rentabilidad de tecnologia mejorada en fincas y limitaciones para la adopcion; analisis de costos de procesamiento y mercad...
Advances of the mycorrhiza project of CIAT's Cassava Program are highlighted. Objectives include the collection, maintenance, multiplication, and testing of mycorrhizal strains and determination of favorable cultural practices for maintaining mycorrhizal activity during the growth period of cassa...
Results of agronomic research are reviewed and suggestions for further research are given. Research is needed to derive methods that will enable farmers to integrate climbing beans into their current crop production systems. The wide gap between genetic yield potential and actual results on farme...
Se revisan los resultados de la investigacion agronomica y se dan sugerencias para otras investigaciones. Se necesita que la investigacion proporcione metodos que faciliten al agricultor la incorporacion del frijol trepador a sus sistemas tradicionales de produccion de cultivos. La gran brecha en...

In order to identify factors limiting bean production in Narino, Colombia, meetings were held in different localities with groups of farmers, and later, some of them were surveyed at random. Results are analyzed including land preparation; planting time and distance; fertilizer aplication times, ...
Con el fin de conocer los factores limitantes de la produccion de frijol en Narino, Colombia, se realizaron reuniones con grupos de agricultores en los diferentes municipios y posteriormente se encuestaron algunos al azar. Se analizan los resultados incluyendo preparacion del terreno; epoca y dis...

In coastal Ancash, Peru, on-farm studies were conducted on fertilization (0-0-0 and 40-60-0 kg/ha NPK), density (90,000 and 120,000 plants/ha), and weed control (2 and 3 manual weedings, resp.) to determine their effect on yields of beans in monoculture. Significant differences among treatments w...
Se realizaron ensayos exploratorios de fertilizacion (0-0-0 y 40-60-0 de NPK), densidad (90,000 y 120,000 plantas/ha), y control de malezas (2 y 3 deshierbas manuales, resp.) en campos de agricultores en la costa de Ancash, Peru, para determinar su efecto en el rendimiento del frijol en monoculti...

Presents information on work carried out by ILCA in Ethiopia to develop an animal-drawn implement for reduced tillage, row planting and inter-row weeding. Comments briefly on the advantages and initial field test results on the implement.
Recent information on the biological balance between purple nutsedge (Cyperus rotundus) and cassava is analyzed; the possibilities of influencing this balance to favor cassava are also studied. The slow initial growth of cassava highly favors the development and propagation of C. rotundus, result...
