Harvested soybeans on the LTER Main Site between September 30, and October 2, 2015, treatments T1, T2, and T3; all replications.
Please notes below for specific dates for individual harvest dates for each specific plot.
Number of soybean rows harvested from both east and west sides were counted and recorded to determine total area harvested.
Plot weight was determined by unloading soybeans from the combine to a Brent Weigh Wagon, by Unverferth Co.
At harvest each plots were divided into two distinct sides, the west side and the east side. With 15' of the north and south ends 'headland passes of each plot being included in the west side data.
The west side of each plot contained a headland pass across the entire width of the plot on the north and south end of each plot and ~ 107-110 rows of soybeans for T1-T3 and 54 rows for T4 located on the west side of each plot. The created headland was one pass across both north and south headland with the JD 9410 combine with a grain 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.
Grain yield and moisture from treatments 1-4 across all six replications were recorded. However, the standard agronomic yields recorded on the web page 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 and headland passes. 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.
