Using cross-sectional household data from a field survey conducted in Cheung Kaeub commune in 2004, this paper explored the effect of off-farm income from industory on rice production. By using with and without comparative study approach and other data analysis methods consisting of two-independent samples t-test, production function, correlation and economic profitability analyses, this paper found the effect of off-farm income from industory on rice production as follows: (1) off-farm income has a storong correlation with input investment and rice output, (2) farm households with off-farm nicome haevested roce yields around 3 tones per hectare, while farm households without off-farm income obtained around 2.5 tones per hectare. This large difference in crop yield attained by farm households with and without off-farm income was found to be highly significant at 1% percent level of confidence, (3) Farm households with off-farm income could get economic profit around 49 thousand rices per hectare from rice enterprise., while farm households without off-farm nicome lost around 38 thousand riels per hectare due to poor performance of the crop, and (4) the results of production function analysis indicated that three important factors of production consisting of input investment, land and labor contributed to rice output significantly. Based on the standardized coefficient beta of each variable, it can be implied that if farmers could increase operating expences on inputs by one percent, rice output would increase around 0.439 percent, holding other factors constant. Similarly, one percent increase in cultivated area, rice output would increase by 0.309 percent, holding other factors constant. One percent increase in the amount of labor used on rice sultivation, rice output will about 0.200 percent, holding other factors cnstant. Farm households with off-farm income harvested rice output around 0.205 percent hogher than farm households without off-farm income did.
