Abstract- The study on the factors affecting the net income of the households for mono rice production, rice-upland crop and rice-aquaculture in the Mekong Delta was conducted in July, 2013 which aimed to (1) Assess the main resources of the households; (2) Analyze factors impacting the net income and (3) Propose solutions for improving the net income for rice production, rice-upland crop and rice-aquaculture of households in the Mekong Delta. The analysis method was based on the descriptive statistics, and the multiple linear regressions. The study results showed that: (1) The educational levels of the household heads were low; (2) The farmland was large with 1.95 hectare per household; (3) There are three groups of household having the main net income from agricultural production, and the second net income from the non-agricultural activity; (4) The net income of the mono rice production households was affected by the participation association of the household heads and the farmland area; (5) the net income of the rice-upland crop households was impacted by the family man-days and the production investment in materials; and (6) the net income of the riceaquacultural households was effected by the educational levels, the family man-days and the farmland area. Based on the study results, some solutions for improvement of the household net income were proposed.
