2004 wheat harvest took place between July 12-15, 2004. Please see notes below for specific dates for individual harvest dates for specific plots. Straw was put in windrows behind the combine in T1 and T2 plots so that the straw could be baled and removed from the plots. Straw was chopped back onto the T3 and T4 plots. The chopper is part of the combine when you do not want to bale straw you engage the chopper to chop all the straw behind the combine. Wheat was combined off the plots using a John Deere 9410 combine. Weights were determined using a weigh wagon equipped with weigh cells. Moistures were determined using a Dicky-john grain analysis computer. For all plots, collected the weight of grain in the east and west sides of the plot, percent moisture, and test weight. At harvest each plot was split into two distinct sides, the west side and the east side. Grain yield and moisture from all treatments across all six replications were recorded. However, the standard agronomic yields recorded on the web page, for the year 2004, 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 weed 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.
