Autor: Fujisaka, Sam

From 1987 through 1992 a team of on-farm researchers worked at Claveria in northern Mindanao to improve the productivity and sustainability of the local upland rice and maize-based agroecosystems. Adaptive research goals were to improve crop productivity, control soil erosion, and improve nutrien...


Fujisaka, Sam[Farmer participatory adaptation and adoption of contour hedgerows for soil conservation]Farmer participatory adaptation and adoption of contour hedgerows for soil conservation

Cassava agronomy research in Thailand during 1994-1996 emphasized mainly erosion control, soil fertility maintenance and weed control. Regarding soil erosion control, the planting of cassava in April, at the start of the rainy season, and harvesting in March resulted in the highest soil loss comp...

Since 1987 cassava agronomy research has been conducted by scientists from national cassava programs in Asia in collaboration and with small financial assistance from the CIAT cassava program. This paper summarizes and pulls together the results obtained, mainly corresponding to the period of 149...


Howeler, Reinhardt H.[Agronomy research in the Asian cassava network: Towards better production without soil degradation]Agronomy research in the Asian cassava network: Towards better production without soil degradation

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...
