Spring wheat producers in the northern Plains are wrapping up harvest this week, with widely ranging yield reports coming in from the field. A wet planting season hampered some growers early on, and that was reflected in a wide range of test weight, protein levels and overall yield. Later on in the growing season, heat was the culprit of some yield potential in parts of North Dakota, while growers further south said late-August rainfall wasn’t enough to cause yield erosion. Overall, yields ranged from the mid- to upper-40s to around 85 bushels/acre, farmers report. See the range of spring wheat results here.
