text: Considering cassava's high productive potential, estimated at 90 metric tonnes per hectare (Cock et al, 1979), the low yields are probably due to the fact that in Northeast Brazil, cassava is grown on low fertility soils, under uncertain rainfall conditions, and suffers an estimated 50% reduction in root yield due to pests, diseases and weeds.
