| Abstract: |
We examined seasonal growth profiles developed from AVHRR-NDVI for estimating wheat yield at regional and farm scales in Montana for the years 1989-1997. Both regions and farms showed strong relationships between wheat yields and integrated NDVI over the entire growing season, and with late-season NDVI parameters. The use of AVHRR-NDVI growth profiles at the regional level provided the strongest yield estimates. At the farm scale, the spatial resolution (1 km[sup 2]) limited the certainty for accurate portrayal of field locations. However, our models provide a basis for further examination of time-series satellite data. [ABSTRACT FROM AUTHOR] |
