Growing degree graphs include cumulative lines for 1999 and normal. All graphs include vertical lines indicating planting, silking, and harvest dates, if available. General trends in precipitation and temperature relative to normal are readily observed in the graphs. For more detailed information, a table is included with monthly totals and averages for the growing season. The listed infestation rates and tunnel lengths may not represent the actual extent of damage if the sampling date precedes harvest by several weeks, but it does provide an indication of the level of corn borer infestation at a given location.
Explanatory information is given preceding data summaries for each test.
Tables 1-21 contain results from the standard corn performance tests. Hybrids are listed in order of increasing days to half silk and increasing grain moisture for the current year so hybrids of similar maturity appear together. The 1999 entrants and entries are listed in the Appendixes. Planting to stand enables evaluation of product performance for the entire growing season. Each harvested plot consisted of two rows trimmed to a specific length ranging from 20 to 30 feet at the different locations.
