Harvested corn in the LTER Main Site Treatments T1, T2, T3, and T4 corn plots, all replications.
Dates plots were harvested:
October 18, 2017: T1R1, T1R2, T1R3, T1R4, T2R1, T2R2, T2R3, T2R3, T3R1, T3R2, T3R3, and T3R4.
October 19, 2017: T1T5 T1R6, T2R5 T2R6, T3R5, T3R6, T4R1, T4R2, T4R3, T4R4, T4R5, and T4R6.
Before harvest we removed 'harvested' a 15' headland pass on all north and south end of each plot. The grain harvested from the 'headland pass' was not recorded as weight of grain removed from each plot. The reason for the 15' headland pass on both end of each plot was so that we would have room to turn the combine around in the alleyway.
We record a weight from all the east and west sides of all the plots however all the plot weights were joined and one weight was recorded from each plot.
2016 was the first year that the harvest plot weight was from the entire plot area not just the weight from the east side of each plot.
2017 was the second year (first year for corn) that the weight from each plot was from the entire plot area not just the weight from the east side of each plot.
Total number of corn rows were determined prior to harvesting the corn to determine the width of the area harvested. At planting time in spring of 2017 we made 19 passes with a 15' JD 1730 corn planter (30 inch rows). 19 * 6 rows/pass = 114 rows.
Corn was harvested with a John Deere 9410 combine.
Plot weight was determined by unloading corn from the combine in to a Brent Weigh Wagon, by Unverferth Co., equipped with three load (weigh) cells. The three load cells are located on the axle and tow tongue (hitch) of the wagon.
Moisture and test weights were determined using a portable Dicky-john GAC500 XT grain analysis moisture tester.
Corn variety harvested was (Dekalb DKC52-84 RIB) corn hybrid in T1, T2, and T3 plots.
Corn variety harvested was ? in T4 plots.
Estimated harvest time was from 8:30 a.m. - 6:30 p.m. (this estimate is just harvest time it does not include equipment set up and equipment clean up time).
