Crop production in the sandy area of Hai Lang district is transforming, shifting from traditional mono-cropping models to improved cropping patterns such as annual intercropping, annual crop rotation, and mixed patterns of intercropping and rotation. This study estimated the income effect of the adoption of improved cropping patterns, using primary data collected from a sample survey of 186 households from two selected communes in a sandy area of the district. It was found that farmers’ likelihood of adoption of improved cropping patterns is significantly affected by the age of the household head, the household’s wealth status, the plot area, participation in extension training, and access to credit. Using the propensity score matching approach, the income effect of adoption was estimated. The adopters at the study site attained income that is 20–25% greater than matched non-adopters.
