Results are presented of various trials with cassava. The importance of DM production and factors affecting it, such as LAI and leaf inclination, are discussed. The relative importance of DM production and its distribution, particularly in relation to spacing, are reviewed. The author suggests a ...
Se presentan los resultados de varios ensayos con yuca. Se discute la importancia de la produccion de MS y los factores que la afectan, tales como el IAF y la inclinacion de la hoja. Se revisa la importancia relativa de la produccion de MS y su distribucion, particularmente en relacion con la den...
A system for rapid propagation of cassava is described, including detailed characteristics of the installations (propagation chambers and rooting area), materials needed and process to be followed. The advantages of this system are: (1) it is the only way of rapidly propagating promissory var. in...

Las ventajas de este sistema son: 1) es la unica manera de propagar var. p...
Adequate resources and infrastructure for the exchange of cassava germplasm are discussed according to the type of material received (sexual seed, cuttings, and meristems). The final objective of exchanging cassava germplasm among different countries is to obtain improved var.; in order to do so,...
Se analizan los recursos y la infraestructura adecuados para el intercambio de germoplasma de yuca segun el tipo de material que se reciba (semilla sexual, estacas y meristemas). El objetivo final del intercambio de yuca entre diferentes paises es obtener var. mejoradas; para lograrlo se requiere...

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, ...
Different physiological characteristics of the cassava plant, which can be used as selection parameters, are reviewed, namely LAI, HI, biomass production, plants with amphistomatic leaves, and C4 photosynthesis. Experience indicates that it is better to select var. showing lower yield reduction u...
Se revisan diferentes caracteristicas fisiologicas de la planta de yuca que se pueden utilizar como parametros de seleccion: IAF, IC, produccion de biomasa, plantas con hojas amfistomatosas y fotosintesis C4. Se enfatiza que se debe tratar de seleccionar var. que presenten menor disminucion en co...

Development models are outlined to shed light on cassava's potential to generate economic growth. Since small cassava producers are to a large extent marginalized from the development process in Latin America, the CIAT cassava program has tried to define development strategies that are clearly or...
Se esbozan algunos modelos de desarrollo para aclarar el potencial de la yuca en la generacion de crecimiento economico. Debido a la marginacion de los pequenos agricultores de yuca del proceso de desarrollo en America Latina, el programa de yuca del CIAT ha tratado de definir estrategias de desa...
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...
A series of trials were carried out using cassava. Crop growth rate increased with leaf area up to LAI 4; root growth rate increased up to LAI 3-3.5, then declined. LAI is determined by leaf size, leaf formation rate and individual leaf life. Leaf size reached a max 4 mo after planting and then d...

In recent studies of cassava at CIAT, net CO2 uptake rates of 20 to 35 ?mol CO2 m?2 s?1 were commonly observed. Cassava photosynthesis has a high optimum temperature (35°C) and a wide plateau (25 to 35°C) corresponding to the temperature range under which cassava is cultivated. Leaf photosynthesi...
