Missouri Grain Summary by County
Metadata[+] Show full item record
Information includes historical acres planted (1975-1999), harvested acres (1945-1999), yield (1945-1999), production (1945-1999), ratio of harvested to planted acres (1975-1999), and yield risk (1963-1999) for corn, soybean, and wheat. Yield risk is a five-year moving standard deviation. Standard deviation is a measure of dispersion around the average. A higher value indicates greater variability of yield over the previous five years. The last alternative to choose from allows you to view the difference in historical risk between corn, soybean, and wheat from 1980-1999. Instructions on how to interpret this measure of risk are described in each individual file. Data for the information available at this web site was made available from the Missouri Department of Agriculture, United States Department of Agricultural, and Missouri Agricultural Statistics Service.
