Metodología simultánea de screening por la efiencia en el uso de bajos niveles de fósforo y por la tolerancia a toxicidad de aluminio y manganeso en suelos adversos para fríjol (Phaseolus vulgaris L.)
The growth of 9 grain legumes under irrigated conditions was analyzed at CIAT to evaluate bean efficiency in grain production. The representative genotypes of each sp. were selected from preliminary var. evaluations. The most efficient spp. in yield production/day were soybeans, cowpeas and beans...

Estudio comparativo de Phaseolus vulgaris con ocho leguminosas de grano diferentes
Research on lima beans (Phaseolus lunatus) was conducted regarding adaptation, resistance to common bacterial blight (Xanthomonas phaseoli), resistance to leafhoppers (Empoasca kraemeri), and cyanide concn. in lima bean seed. In adaptation studies 36 climbing lima bean lines were selected from th...

Se llevó a cabo una serie de ensayos con yuca (Manihot esculenta Crantz). La tasa de crecimiento del cultivo aumentó proporcionalmente con el índice de área foliar (IAF) hasta un IAF de 4, y la tasa de crecimiento de la raíz aumentó basta un IAF de 3 -3,5 y luego disminuyó. El IAF se determina de...
