A longterm experiment was conducted at Sukadana red yellow podzolic soil during 1981/82-1984/85 growing seasons. Intercropping of upland rice with cassava followed by peanut between cassava rows with the straw of intercropped plants i.e. rice, corn and peanut continuously applied as mulch could be recommended for soil fertility maintenance. Yield potential of upland rice and peanut as well as corn depend on light intensity affected by cassava as main crop. Application of nitrogen and potassium fertilizers in each planting season increased root yield significantly within four consecutive years. However, more research is needed to maintain yield stability after the fourth growing season.
