[Objective] The aim was to explore a suitable cultivation approach for cassava in Hunan province. [Method] With SC9(Southern China 9) as test materials, the test included four treatment methods, as follows: control group by traditional cultivation with crops uncovered(CK), treatment 1 by traditional cultivation with mulch coverage, treatment 2 by powder ridge cultivation with crops uncovered, and treatment 3 by powder ridge cultivation with mulch coverage. Water and fertilizer managements were kept the same. [Result] Compared with traditional cultivation(CK), the treatment by powder ridge cultivation with mulch coverage performed better. Specifically, yield per unit area reached 44 790 kg/hm2, increasing by 86.38%(20 760 kg/hm2) than that of control; starch content grew by 17.24%. The cultivation method considerably improved cassava yield and quality. [Conclusion] Powder ridge cultivation with mulch coverage is a cultivation approach suitable for cassava in Hunan province.
