    The progress achieved by CIAT's cassava program through training activities related to the crop in Latin America, Asia, and Oceania are given. In collaboration with the training office at the Centro Internacional de Agricultura Tropical, the cassava program in 1980 trained 38 professionals from 15 countries (Brazil, Colombia, Mexico, Bolivia, USA, Thailand, Dominican Republic, S. Africa, Ecuador, Haiti, Honduras, W. Germany, the Netherlands, Great Britain, and Italy).

    A guideline for carrying out regional trials in cassava is given, including necessary steps (identification of collaborators, selection of sites, identification of person in charge, planting and harvesting season, exptl. design, plot size, and border rows); the technology used (selection and treatment of cuttings, plant density, land preparation, planting position, application of herbicides and fertilizers, pest and disease control); necessary visits (a min. of 7); and final agronomic trials to determine optimum density and age of var. at harvest.

    The Llanos region of Colombia represents one of the last large agricultural frontiers and is undergoing a rapid conversion from naturalized savanna to intensive agriculture with high agrochemical inputs and tillage. This massive land-use conversion has considerable impact on ecosystem services and biodiversity, particularly soil macrofauna, yet the full implications of this land-use shift for long-term agroecosystem productivity are poorly understood.

    The objectives of the diagnosis of bean production are to (1) contribute criteria for the design and completion of on-farm trials of the new bean technology and (2) to take information to research centers that helps define bean research priorities. A summary is presented of the methodology suggested and practiced in national and international courses on on-farm research carried out by CIAT's bean program.

    The major citrus production of the world are located between 20-40 degrees north and south latitude. In these conditions the mandarins get the best internal and external qualities.‘Arrayana’ is the main mandarin cultivated in Colombia tropical lowlands (around 04° N). This variety is characterized by a high concentration of the harvest in december and january because it has only one principal bloom in the year (two weeks after onset of rainy season); and an average external quality that prevents it from being highly competitive.

    Acid sulfated soils are characterized by high amounts of iron and sulfur, which in presence of air are oxidized and form sulfuric horizons extremely acidic, generating environmental changes ranging from water pollution to problems associated with fertility and crop production, among others. This research was conducted in order to identify suitable plant species to control the acidity of these soils in the town of Paipa, Boyacá, Colombia. A completely randomized experimental design with 6 treatments and 3 replications was implemented in potting shed; there, the response of Beta vulgaris L.

    La Mojana region is located in the North Coast of Colombia. It is part of the alluvial extensive plain, where the Cauca, San Jorge and Magdalena rivers flow together. The region is representative of the tropical humid forest, and is affected by annual flooding cycles. The predominant soils are inceptisols, entisols, oxisols and vertisols. Human activity has been reported since pre-Columbiam times, with the Zenu culture.

    The aim of this study was to determine some aspects of the distribution and habitat availability for the subspecies Tapirus terrestris colombianus in the low lands of the northern Central Mountain Chain in Colombia, which is known as the Antioquian Northeast. The results confirm the presence of this subspecies in 20 new recording localities. The habitat availability was estimated by locating the records on images of vegetation covertures, being primary forest the predominant vegetation followed by bushland.
