Favorable weather conditions allowed U.S. corn  producers to harvest another 9% of their crop last week, but high crop moisture levels continued to limit harvest progress.
There were no nationwide comparisons for last year of the five-year average as USDA has normally discontinued crop progress updates by this time of year.
In the top corn state of Iowa, harvest was 94% done as of Sunday, up from 87% a week earlier, while in the No. 2 growing state of Illinois, harvest reached 85% complete, up from 72% a week earlier.
Harvest continues to lag worst in North Dakota, where producers had combined 53% of their crop by Sunday against 79% a year earlier and a five-year average of 93%.
Snowfall across many areas of North Dakota slowed harvest activity last week, although freezing temperatures improved field conditions in wet areas of the state.
