2001-2002 Small Grain Performance Tests

Research Report Number 682
Results of the 2001-2002 performance tests of small grains grown for grain and forage are printed in this research report. Grain-evaluation studies were conducted at five locations, including Tifton, Plains, and Midville in the Coastal Plain region, Griffin in the Piedmont region, and Calhoun in the Limestone Valley region. Small grain forage evaluation tests were conducted at four locations in Georgia, which included Tifton and Plains in the Coastal Plain, Griffin in the Piedmont, and Calhoun in the Limestone Valley region, and at Marianna, Florida. For identification of the test locations, consult the map below.
Grain yields are reported as bushels per acre at 13.5% moisture for wheat, 13% for triticale and rye, 12.5% moisture for oats, and 12% moisture for barley. Additional agronomic data such as plant height, lodging, disease incidence, etc., are listed along with the corresponding yield data. Information concerning culture and fertilizer practices used is included in footnotes. Since the average yield from several years indicates a variety's potential better than a single year's data, multiple-year yield summaries are included.
In order to have a broad base of information, a number of varieties, including experimental lines, are included in the tests, but this does not imply that all are recommended for Georgia. Varieties best suited to a specific area or for a particular purpose and agreed upon by College of Agriculture scientists are presented in the Cultural Practices section of this report and also in the 2002 Fall Planting Schedule for Georgia (available at your county extension office). For additional information, contact your local county extension agent or the nearest experiment station.
The Least Significant Difference (LSD) at the ten percent level has been included in the tables to aid in comparing varieties and tests. If the yields of any two varieties differ by the LSD value or more, they may be considered different. Bolding is used in the performance tables to indicate entries with yields statistically equal to the highest yielding entry in the test. The standard error (Std. Err.) of an entry mean is included at the bottom of each table to provide a general indicator of the level of precision of each variety experiment. The lower the value for the standard error of the entry mean, the more precise the experiment.
