*5.4. Potential Limitations*

Environmental factors such as sun angle, soil types/moisture, agronomic practices, etc., can contribute to the reflectance and nutrient differences at the plant the level. Given the number of samples collected at each location, this study is not meant to be a representative sampling for all tef varieties at varying growth stages around the world. To establish more generalized models that can be

applied to a broader range of locations/tef varieties, future studies should focus on obtaining a greater number of samples across a greater number of location for multiple tef varieties.
