The natural condition in Kampuchea is ideal for rice production. Rice can be planted three times in wet season, dry season and early wet season. The experimental yield can reach 12.0 t/hm2, but most of the field only planting one season in rainy season because of the lack of irrigation. It has good quality, early maturity, and average yield of 3.0 t/hm2. There are no damaging pests or disease as a result of tropical monsoon climate condition, low input of chemical fertilizer and pesticide, which formed a balanced ecosystem. It has broad prospect of large-scale mechanized cultivation and high yield potential. By improving the irrigation system, applying proper material investment and technical support, the rice yield may be dramatically increased and the country could be created as an important rice production base to ensure regional international food safety.
