Weather and soil conditions affect composition, but the relative ranking of hybrids does not change greatly. A higher protein hybrid will be higher than average regardless of environmental conditions that raise or lower the averages. The protein percentages reported are measures of crude protein and may not give an accurate indication of feed value if feed rations are balanced on individual amino acids rather than crude protein content. Specialty high oil corns are evaluated in a separate test. Greensnap Greensnap happens when severe windstorms occur while corn plants are growing rapidly, usually before pollination.
Corn stalks snap off at about a foot or two above the ground.
This year, many areas of the state experienced some greensnap. Greensnap was so severe at the Pocahontas County and Mills County locations that these locations were not harvested. At other locations that experienced some greensnap, yields reported this year reflect the reduction in yields caused by greensnap. Also, the actual plants that greensnapped were counted as broken stalks and included in the stalk lodging percent columns in the reports. The District 3 test was planted on farms operated by Mick Reigelsberger near Rolfe in Pocahontas County, Richard Bertram near Holland in Grundy County, and Dave Broghammer near Manchester in Delaware County.
