Research results obtained during 1975-87 on the biocontrol of cassava pathogens are summarized with emphasis on the use of fluorescent pseudomonads as biocontrol agents in different cassava production systems. Evidence of biocontrol of Uromyces spp. by the mycoparasite Darluca filum is reviewed. ...
Bean seeds var. Calima were stored in airtight containers during 32 wk., at 30 degrees Celsius and 7 moisture levels between 10.3 and 14.2 percent (humid basis). Every 2 wk., the physical, physiological, and sanitary quality of the seeds was evaluated by doing individual lot samplings of each moi...
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 (...
Research was conducted to evaluate the application of a fungicide mix in the various stages of crop development and the effect of different selection systems in the production and final quality of the seed produced. Two cv. (Calima and PVA 916), 4 selection systems (plants, pods, seeds, and P + V...
Research was conducted at the Centro Internacional de Agricultura Tropical (CIAT) in 1980 in order to solve the problem of low cassava yields in Loja, Ecuador, Objectives were: (1) to determine the effect of vertical and horizontal plantings of cuttings on the emergence and competitive vigor of c...
During 1981 the introduction of germplasm was continued with an additional 147 clones from Brazil in the form of aseptic meristem cultures. Cassava germplasm bank evaluation for adaptation, resistance to diseases and pests, yield, and root quality is in progress in the north coast of Colombia (Me...
