Abstract or Summary
  • A study was conducted using data collected from a sample of mint and vegetable farmers in the Willamette Valley of Oregon. The study identifies the influence of demographic differences, economic factors and irrigator attitudes on irrigation efficiency. Only two of the 19 characteristics theorized to influence irrigation efficiency proved to be statistically significant in both of two models. These significant variables, crop type (CROP), soil type (SOIL) suggest that a farmer's irrigation efficiency is unaffected by personal characteristics or attitudes. According to these results, the irrigator apparently applied the water that she deemed necessary, a decision based solely on the needs of the crop and the water-holding capacity of the soil.
