This research aims to evaluate the effectiveness of fertilizer extension and fertilization in the women's farmer group "Cerdas" in Lawelu Village, Ulumoro'o District, West Nias Regency. The research method used a quantitative approach with data collection techniques through observation, structured interviews, and questionnaires. The results showed that 75% of respondents experienced an increase in understanding of fertilizer types, doses, and application times after counseling. However, implementation in the field is still constrained by limited access to subsidized fertilizer (60% of respondents). The conclusion of this study states that extension is effective in improving knowledge but requires policy support to improve fertilizer accessibility.
