Abstract: Abstract: According to the conclusion of cassava research in China, the important rank for cassava nutrition are N>K2O>P2O5, it suggested that N:P2O5:K2O ratio is 2-4:1:2-4 for continues cassava production, P fertilizer can always keep low level, but the N and K2O ratio need to be gradually increase year after year. the recommendation optimum fertilizer range per year for moderate fertility soil is about 50-100 kg/hm2 N and K2O, 25-50 kg/hm2 P2O5. Meanwhile, Ca, Mg, S, B, Zn and Cu fertilizer could be selected applying in some region according to local soil condition. it needs attention to apply Sulphate of Potash Magnesia (SPM), Calcium Magnesium Phosphate,bio-organic fertilizer,burned soil, other FYM, waste stem and leaves of cassava and intercrop etc. to supply organic matter and micro nutrition. Moreover, suitable use Plant Growth Regulators, try to apply basic and seeding fertilizer.
