The impact of improved technological components depends to a large extent on the appropriateness of the intervention for the end-user, the efficiency of the technology transfer mechanism and the socio-economical and political conditions of the technology target area. In order to optimize impact t...

Cassava in Asia: Designing crop research for competitive markets
If a wholesale yield improvement of major crops by new high yielding cultivars was the definition of "Green Revolution", it was also a tacit expectation that a success similar to that in rice or wheat would be repeated in cassava when a cassava varietal improvement program was established at CIAT...
Using the farm as unit of analysis, diagnosis processes aimed at improving production systems are reviewed. Within a country, diagnosis should be conducted at different hierarchical levels: local (interaction between the production system and the input distribution sector, the marketing sector, p...
Se consideran los procesos de diagnostico dirigidos a mejorar sistemas de produccion, utilizando la finca como unidad de analisis. Dentro de un pais, el diagnostico se realiza a diferentes niveles jerarquicos: local (interaccion entre el sistema de produccion y el sector de distribucion de insumo...

During the past decade (1990-2000) the area planted to cassava in most countries in Asia has generally decreased, while production has remained stable or also decreased. Cassava yields have increased mainly in India, Indonesia and China but remained nearly the same in Malaysia, Thailand and the P...

Cassava agronomy research in Asia: Has it benefitted cassava farmers?
Cassava is after maize an important subsidiary crop in Vietnam. The amount of production used for human consumption is now only about 10-20 percent, that for animal feed increased to about 30 percent, for industrial processing about 30-40 percent, while about 20 percent is used for other requirem...
Five cassava cultivars for industrial purposes, Rayong 3, Rayong 60, Sriracha 1, Rayong 90 and Kasetsart 50, were released during 1984-1992. New cultivars were simultaneously evaluated in research stations and farmers' fields in 53 locations during 1991 and 1992. Yields of each cultivar were regr...

Cassava (Manihot esculenta Crantz) is an important food security crop for poor rural communities, particularly in Africa. At household level, cassava landraces used for cultivation are mainly selected based on farmers' interests, leading to very particular diversity evolution over generations. Th...

Tracking crop varieties using genotypingbysequencing markers: a case study using cassava (Manihot esculenta Crantz)
High starch yield is the most important trait for commercialized cassava starch production. Furthermore, cyanide present in cassava roots poses a health challenge in the use of cassava for food. Cassava genotypes have varying maturity periods that are also environmental dependent. This study aime...
