U.S. farmers east of the Mississippi River made good planting progress, while growers in western areas of the Corn Belt were slowed by rainy weather, a U.S. Agriculture Department report showed on Monday.

The USDA's weekly crop progress and conditions report showed that U.S. corn seeding was 28 percent completed as of April 22, up from 17 percent a week ago and ahead of the five-year average of 15 percent, but down from analysts expectations.
