This course is jointly developed by the Tropical Crops Genetic Resources Institute of the Chinese Academy of Tropical Agricultural Sciences (CATAS), under the Ministry of Agriculture and Rural Affairs of China, and the Guangxi Subtropical Crops Research Institute. It aims to help smallholder farmers acquire key techniques for cassava intercropping, increase land‑use efficiency by 30% to 100%, reduce labor costs through shared weeding, and stabilize annual income by lowering income fluctuation risks. This course provides a systematic, full-process framework covering the entire intercropping process, including the selection of suitable companion crops (short‑cycle, dwarf, and ecologically compatible species), optimal sowing time differences, soil preparation standards (deep, loose, fine, and level), seed stem selection and treatment, and detailed management for three typical models: cassava-peanut, cassava‑watermelon, and cassava‑corn intercropping. It also addresses key practices such as ridge construction, planting density, fertilization scheduling, and post‑harvest residue management. The core technical essentials of the course can be summarized as “Match crops wisely, sow at the right intervals, and manage fields diligently; select short‑stature companions, avoid shading, and harvest before canopy closure; prepare ridges with care, apply balanced fertilizers, and remove residues promptly to maintain soil health.” Through these standardized and actionable guidelines, the course aims to help farmers convert cassava's early‑stage “fallow period” into a productive growing period, thereby improving overall farm profitability, enhancing soil ecological conditions, and strengthening the foundation for sustainable and resilient cassava production.
