5 INTRODUCTION The 07 growing season was the tenth year for the Corn Standardized County Trial Program. The program s goal is to increase knowledge on selected hybrids that are being evaluated in the University of Arkansas Corn testing program ( The trials were a collaborative effort between growers, County Extension agents, Extension specialists, and industry representatives. In the trials, producers followed their normal production practices they use on their farms. The cooperation of all producers mentioned in this publication is appreciated. Producers donate time, equipment and hired labor to make these trials possible. Trials were separated into five districts and within each district hybrids entered were consistent. Districts included the Northeast, Central, Southeast, River Valley and Southwest, representing the major corn producing areas of Arkansas. A map on page 4 shows the counties in each district. Industry representatives and Extension specialists choose hybrids to be entered, and hybrids were required to be commercially available and have been tested/or being tested in the University of Arkansas Corn testing program. All hybrid trials were irrigated with the exception of Logan County in the River Valley and all hybrids were glyphosate tolerant. Relative maturity of hybrids entered ranged from 4 to 8 days. A full list of hybrids entered along with relative maturity and traits can be found on page. Trials were strip trials and were not replicated, but multiple locations within a district do provide useful information on yield potential and agronomic considerations. Information collected in each trial included; soil type, planting date, agronomic production practices utilized by each producer, final plant population, test weight, grain moisture at harvest, plant lodging and yield. Plots were planted with producer equipment and typically were six rows wide by the length of field ( ft). Grain moisture and test weights were recorded by commercial or hand held grain analysis equipment. Grain yields were adjusted to 5.5% moisture. When lodging occurred visual ratings were taken by County Extension agents, Extension specialists and/or producers. In 07, trials were harvested and results reported. Planting dates ranged from March to May 8 with an average planting date of April 9. Planting rates ranged from 8,000 to 40,000 seeds per acre with an average of 4,000. dates ranged from August 5 to October 6 with an average harvest date of September. The authors would like to express their gratitude to the producers, County Agents, and industry representatives that made these trials possible.
