Trends and yield constraints in the production systems of beans and cassava in Latin America with emphasis on research design implications
Agricultural research in developing countries has lacked relevance to farm-level production problems, especially appropriate technologies for small-scale or limited-resource farmers. Currently research institutions are directing their efforts towards these objectives. This paper is a preliminary ...

The role of economists in on-farm testing in agricultural research
In Brazil, the world`s largest bean producer, the annual production value is over US$ billion. Beans contribute more to total national protein consumption than any other product, especially among the poor, who get over 30 percent dietary protein from beans. Available technological options for imp...

An Ex-Ante analysis of the distribution of benefits from technical change among classes of consumers and producers: the case of beans in Brazil
The possibilities of underdeveloped countries to satisfy their needs for food and to improve the standard of Eving through cassava production are analyzed. The following aspects are studied: potential cassava production (current and potential situation), general research policies and areas (var. ...
In L.A., food uses determine the demand for cassava, especially in rural areas, because of problems in marketing this highly perishable crop. Production is stagnant due apparently to the lack of growth in demand. A significant growth market for cassava products is needed; e.g., the alcohol progra...
En America Latina, la utilizacion de los alimentos determina la demanda de yuca, especialmente en las areas rurales, debido a los problemas en el mercadeo de este cultivo altamente perecedero. La produccion se ha estancado debido a la falta de crecimiento de la demanda. Se necesita un significant...

The trends of world cassava production, yield, consumption, trade and prices are discussed for the period 1963-75. Data are given in table form. (CIAT)
Se discuten las tendencias de la produccion mundial de la yuca, su rendimiento, consumo, mercadeo y precios para el periodo 1963- 75. Los datos se suministran por medio de cuadros. (CIAT)
A detailed review on cassava production in intercropping systems is given, based on the following aspects: selection of plant types for intercropping; realtive planting time, planting density and pattern (spatial arrangement); mineral nutrition and fertilization, competition for nutrients; pest, ...
Some of the actual and potential markets for cassava in tropical Latin America are discussed. Data are presented for Brazil (the world's largest cassava producer), Paraguay (the Latin American country with the highest per capita cassava production), the Andean countries, Central America, and the ...
Se discuten algunos de los mercados actuales y potenciales para la yuca en America Latina tropical. Se presentan datos para Brasil (el mayor productor de yuca del mundo), Paraguay (el pais latinoamericano con la mayor produccion de yuca per capita), los paises andinos, America Central y el Caribe...
An in-depth analysis is made of objectives and constraints in cassava development in Latin America. Integrated cassava development projects aim at promoting the organizational intervention by which small-scale cassava farmers are linked to high growth markets. The 6 main activities involved in th...
