Living mulches are vegetative covers that can be grown in association with row crops to reduce soil erosion, improve trafficability, and suppress weeds. Interference by the living mulch can reduce yields of an associated crop. The interference between a white clover (Trifolium repens L. "New Zeal...

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...

Drought is responsible for large reductions in cassava root yields. On-farm root yields can be improved two- to three-fold and quality of fresh and processed products improved by the adoption of recently improved production technologies. The potential usefulness is high for genetic, morphological...
