Combine cylinder speed causes the majority of kernel damage. Keep the cylinder speed as low as recommendations suggest. Reduce concave clearance first to optimize threshing and only increase cylinder speed as needed. For long term storage, immature grain corn harvested at high moistures should be dried to a grain moisture 1 to 2 percentage points lower than the normal moisture of 14 to 15 percent for safe storage. Field conditions for combining are good.
Yields are extremely variable depending on planting date, location and drainage.
Reported yields range from 20 to 50 bushels per acre, with yields in the 30's being more typical. The late planted, immature soybean fields, with potential grade problems and lower yields, have yet to be combined. In some areas, the lateness of the soybean crop interfered with winter wheat seeding and acreage is down. In other areas such as Peel, where winter wheat was planted on the unseeded acreage that was too wet to seed this spring, wheat acreage is up considerably. Forage Some late harvesting of forage is taking place, depending on whether the feed is needed.
