3 PREFACE In this research report, the results of the 2012 corn performance trials are presented. Corn performance trials were conducted at six locations throughout Georgia (see map inside back cover) in Short-season and mid-season hybrids were planted at Tifton, Plains, and Midville in the Coastal Plain region, at Griffin in the Piedmont region, at Calhoun in the Limestone Valley region, and at Blairsville in the Mountain region. Hybrids used for silage were evaluated at Tifton, Griffin, Calhoun, and Blairsville. At each site all plots within a maturity group were seeded at the rates specified and not thinned, and the populations at harvest are included in the tables. Information concerning fertilization and cultural practices used in each trial is included with the tables. A plot combine was used for grain harvesting, and yields were adjusted to 15.5% moisture. Since data averaged over several years indicate a hybrid's yield potential better than data from only a single year, average yields over several years are included in this report. The least significant difference (LSD) at the 10% level has been included in the tables to aid in comparing hybrids. If the yields' difference of any two hybrids exceeds the LSD value, they can be considered different in yield ability. Bolding is used in the performance tables to indicate hybrids 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 experiment. The lower the value of the standard error of the entry mean, the more precise the experiment. Producers of hybrid-seed corn are invited to enter their hybrids in the Georgia performance trials. Most hybrids entered are commercially available in Georgia, but a few experimental hybrids are also entered. Entry of a hybrid in these trials does not imply endorsement or recommendation by the University of Georgia College of Agricultural and Environmental Sciences.

7 2012 Corn Performance Tests Edited by Anton E. Coy, J. LaDon Day, and John D. Gassett The Season Georgia experienced another year of lower than normal rainfall. The state was dry as of March 1, although there was adequate planting moisture in most areas. Planting progressed well ahead of 5-year averages with 96% planted by mid-april. By early May, only a quarter of the state had adequate moisture. Except for southeastern Georgia, drought conditions continued through June. Irrigation began during early vegetative corn growth and continued through black layer maturity in much of the state. Irrigation allowed 2/3 to 3/4 of the crop to remain in good condition throughout the season. Summer thunderstorms caused root-lodging problems with some hybrids. Insect and disease pressure was light in general. Excessive August rains caused some harvest and quality problems in southeastern Georgia. Harvest overall was ahead of average. Seasonal rainfall totals, as shown in the table below, were 6 to 10 inches less than normal in north Georgia, with the most critical area in the Limestone Valley region. In the Coastal Plain area rainfall was 2 to 10 inches above long term average in the east and 14 inches below normal in the west. The area around Plains continued to be the driest for the third straight year. Growing Season Rainfall 1, 2012 Month Blairsville Calhoun 2 Griffin Midville Plains Tifton inches February March April May June July August September Total (8 mo) Normal (8 mo) Data submitted by Dr. I. Flitcroft, Georgia Station, Griffin, GA. 2. Floyd County location. Corn planted totaled 365,000 acres, up 3% from the 345,000 acres in Corn planted for grain was up 6% from Only 295,000 acres were harvested for grain. USDA October crop estimates had Georgia corn production at 190 bu/ac (a new state record) for a total crop of 56.1 million bushels. The increase from 2011's 158 bu/ac was due to more irrigation on irrigated acres and non-harvest for grain of many nonirrigated acres. Anton E.
