2008 corn harvest took place between October 20-21, 2008. Harvested corn in the LTER main site T1 and T2 plots, all reps. T3 and T4 plots were harvested on November 3, 2008. Please see notes below for specific dates for individual harvest dates for specific plots. Plots harvested on October 20, 2008 were: T1R6, T2R6, T2R1, T1R3, T1R2, and T1R4. Plots harvested on October 21, 2008 were: T1R1, T1R5, T2R2, T2R5, T2R3, and T2R4. Entire plot weight was determined by unloading corn from the combine to a Brent Weigh Wagon, by Unverferth Co. Number of corn rows harvested from each plot were counted and recorded to determine total area harvested. Moisture and test weights were determined using a portable Dicky-john GAC500 XT grain analysis moisture tester. Corn harvested was Pioneer 36W66 corn hybrid for T1, T2, and T3. Corn harvested for T4 was untreated Pioneer 36W66. At harvest each plot was split into two distinct sides, the west side and the east side. For 2008 the west side of each plot contained a headland pass across the entire width of the plot and 54 rows of corn located on the west side of each plot. The created headland was one pass across the headland with the JD 6 row corn head (15 feet wide). The reason that we need to create an artificial headland was because we needed more room to turn the combine around in the field/alleyways. Grain yield and moisture from treatments across all six replications were recorded. However, the standard agronomic yields recorded on the web page, for the year 2008, were taken only from the east side of the plots. The decision to post the yield from only the east side of the plots stems from the fact that on the west side of the plot contains a micro plot area. In northwest corner of treatments 1 and 2 are the micro plots that did not receive any weed control, cultivation or herbicides. Because of the competition from the weeds in the micro plots the decision was made to record the official yields from the east side of the plots. The micro plot area measures 50 ft (15 meters) from the north edge of the plots towards to south and 133.3 ft (40 meters) from the west edge of the plots towards the east. The micro plot area in treatments 1 and 2 that did not receive any weed control was mowed down before harvest.
