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...

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 ...

A descriptive and integrated look at the physiology of the bean plant is presented. Initially, the basic physiological processes that determine bean yields are discussed, namely (1) metabolic events such as photosynthesis, respiration, and N metabolism, which have a direct effect on growth, and (...

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...

Studies on the biology and damage caused by bean pests Diabrotica balteata and Cerotoma facialis have been conducted at CIAT since 1977. The biology of the 2 species is similar in many aspects. Life cycle is as follows: eggs, 6-7 days; 1st larval instar, 3-4 days; 2nd instar, 2-3 days; and 3rd in...
