FIRST is about 87% finished for the 2023 harvest with 40 locations to report as of this writing. The majority of plots remaining are corn trials around the program, with 9 bean plots to go.
Yields in Iowa have been better than expected, particularly in southern Iowa. FIRST Manager Randy Meinsma noted that most farmers are amazed at the yield numbers considering the dry weather. Illinois saw tremendous recovery from the early-season drought there. However, a wet spring was followed by very dry conditions in Minnesota, but so far there are still decent yields and good plot data. South Dakota trials also experienced a good deal of drought stress, with the outstanding plot so far at Jefferson, SD.
One of the more difficult areas is Michigan, where it was bone-dry post planting, with emergence issues around the plots. In northern Indiana and Ohio, the full-season corn came into October measuring high in moisture and has been slow to dry down. At this writing, harvest in Missouri, Iowa, Illinois, and Nebraska is finished. So far on the season, corn and soybean yield reports have been published within 1.2 days of harvest on average.
