Tetemotaha Village implements a surface irrigation system to overcome water availability constraints affecting green mustard productivity. This study aims to: 1) analyze the impact of implementing the surface irrigation system in Tetemotaha Village, and 2) identify the factors influencing the increase in green mustard agricultural productivity in the village. A descriptive qualitative approach was employed in this research. Informants included green mustard farmers utilizing surface irrigation, village officials, and the village head. The results show that the implementation of the surface irrigation system has a positive effect on increasing green mustard productivity. The system provides a stable water supply throughout the planting season, ensures more even water distribution, and allows for regular management by farmers. Sufficient and consistent water availability supports optimal crop growth, raising crop yields from an average of 4–5 tons per hectare to 7–8 tons per hectare. Key factors contributing to this productivity increase include: 1) adequate and evenly distributed water availability, 2) good soil condition and fertility, 3) the use of superior seeds, and 4) proper application of both organic and inorganic fertilizers.
