The System of Rice Intensification (SRI) has been evaluated and effectively applied on irrigated land of more than 40 countries and 22 provinces in Vietnam. However, SRI has not been applied in rain fed land yet. Findings from the study on application of SRI on the rainted land in Bac kan province in summer rice crop 2010 indicated that SRI techniques creating favor conditions for rice. With these conditions, genetic features of the rice were motivated to growth and develop on this land. Transplanting with young seedlings and lower density combining with weed control by hand weeder encourage rice tillering and root growth and development. In SRI condition, reducing infection of sheath blight, strengthening accumulation of dry mater, and as result increasing rice yield. This helps to improve rice productivity in this difficult area and adaptation to climate change.
