Soil erosion is one of the most series problems for the agricultural sector in Ethiopia. There is a need to understand the effective soil and water conservation practices. Therefore, feasible, easy, socially acceptable and environmentally friendly soil conservation practice is essential in the study area due to existence of severe soil erosion. The objective of the study was to investigate the farmers' adoption of Vetiver grass hedgerows for soil and water conservation in Haru district, Western Ethiopia. The data were collected through questionnaire survey; FGD (Focus Group Discussion), KII (Key Informant Interview) and observation. Quantitative and qualitative sources of data were used for the study. Both primary and secondary types of data were also employed in this study. The quantitative data were analyzed with the help of SPSS version 20 and analyzed using descriptive statistics and Chi-square test. Whereas, the qualitative data were analyzed by descriptive narrations. Majority of respondents reported that soil erosion exists on their farmland at different degrees which hinders crop productivity. The study confirms that 71.3% of respondents practice Vetiver grass for soil and water conservation, whereas, 28.7% of respondents do not practice Vetiver grass for soil and water conservation. There is statistically significant association between knowledge of households and the use of Vetiver grass, which influences their willingness to practice. The study indicated that sex, age, educational status and family size of sample respondents have showed statistically significant association with farmers' practice of Vetiver grass for soil and water conservation.
