Several physical and biological factors that limit cassava productivity are described: temp. and photoperiod, soil water availability, RH, soil characteristics (fertility and pH), and pests and diseases. Six edapho--climatic zones (ECZ) for cassava production are defined on the basis of temp.: lo...
