Modelling of multiple regression analysis was used in inferential statistics. The result showed that agri-entrepreneurs self-efficacy level, creativity and innovation level, and risk preference level have a significant impact on the agri-entrepreneurship performance. Based on univariate analysis self-efficacy has the most significant effect on agri-entrepreneurship performance followed by creativity and innovation skill, and risk preference level. Although variables are jointly regressed in bivariate regression, coefficients are decreased. This study concluded that agri-entrepreneurship performance of agri-entrepreneurs of Surkhet district is more determined by self-efficacy level.
