In almost every country women tend to participate in labor force less likely than men due to many reasons. However, there is also gap among females themselves on how much time they spend on labor time attributable to age, education and any characteristics of females. The study assessed determinants of female irrigation participation using probit model based up on data obtained from sampled population of randomly selected Dembi Dima and Dembi Gobu kebeles of Bako Tibe Woreda. Accordingly, of all included variables in the probit model, age, presence of young child at home, household size, land and accessibility of land to irrigation significantly affect female irrigation participation while education of female, sex of household head and extension services are found to be insignificant even at 10% of level of significance. Above all, accessibility of land to small river is the main determinants of irrigation participation since there are few female whose land is proximate to river and not willing to participate.
