For this study three kebels were randomly selected and 178 respondents were sampled. Both descriptive and econometrics analysis were employed. In order to evaluate household food security, household food balance model were employed, Tobit model was used to assess rate and intensity of adoption and logit model was used for determining factors affecting household food security and adoption of rice technology and also ordered econometric analysis took place to categorize and determine the factors affecting household food security status. Results of descriptive analysis showed that adopters of improved rice varieties as compared with nonadopters are characterized by having better agricultural extension and educational status, younger age , smaller family size than none adopter four variables are found to significantly determine adoption and intensity of improved rice varieties .those are education level, member ship in cooperative ,access to credit affects positively while family size affects negatively. Factors affecting food security of household indeed adoption of improved verity, membership in, cooperative are those which have positive impact and proportion of land for IRV training has negative impact. Finally, household food security classified into four categorized by ordered logistic regression in to food secured, moderately in secured, severely in secured and food in secured. The study concludes that socioeconomic factor had significant effect on adoption of IRV whereas they also influence household food security status. The research Recommended that recommends that rice production programs should be designed to improve the intuitional and socioeconomic characteristics of rice farmers in the area and promotion of Agricultural mechanization and food science research interventions be strengthened more Seed multiplication and dissemination of improved varieties should be given due attention.enFood securityintensityadoption of technologyIRVThesis
