The criteria for technology design are as follows: suitable for areas presently marginal for agricultural production; low inputs; give a nonperishable product for transportation; simple to transfer and easy to manage, requiring minimal changes in the traditional systein, Some problems that are be...
Agricultural development in Latin America and Africa is briefly analyzed, with particular reference to bean production. The major trends that affect bean production technology and its role in farming systems include population growth, especially in the highlands of Africa, and urbanization and in...

Concerns for the agricultural resource basis with respect to bean production
The process of identifying the "relevant constraints" and their incidence on breeding programs and agricultural research of international centers are explained and case histories are provided on the role of these 3 types of information (macro stage, micro stage, critical inference stage) related ...

The principal aspects that should be taken into account when constructing the min. infrastructure necessary for a natural cassava drying plant (installations, equipment, and tools) are summarized. The steps followed in the building of the drying floor, the chipping area, and the storage warehouse...

A collaborative project of the Colombian Integrated Rural Development Program (DRI) and CIAT, aimed at establishing small agroindustrial firms to produce dry cassava on the Atlantic Coast of Colombia, is described. It began with the installation of a pilot plant for natural drying of cassava, wit...

Initial research on the physiology of the cassava plant will study the growth cycle of a heavy-and a medium-branched var. The effect of LAI, N and planting density will be determined as well. Other expt will study plant response to N, mineral requirements, induction of flowering, planting dates a...
The present situation of cassava cultivation in Caicedonia (Colombia) is studied after 8 yr cooperation between the Nat. Federation of Coffee Growers and CIAT. From an iitial 60 ha and 8 farmers in 1971, the project had developed more than 1300 ha (90 farmers) by the end of 1978. Yields have decl...
To improve the welfare of the rural poor involved in cassava production in communities in Ceara, NE Brazil, an integrated production, processing, and commercialization project of cassava chips for animal consumption was established. Details are given of site selection, identification of local ins...

When developing breeding programs, it is necessary to take into account certain characteristics of the crop such as method of propagation (vegetative or sexual) and physiological factors affecting yield (i.e., the roots in cassava). Genetic improvement, as well as the specific breeding objectives...
