LINCOLN, Neb. (AP) – Recent warm weather has helped crops develop in Nebraska, but wet conditions on the southern side of the state hindered the wheat harvest.  The U.S. Department of Agriculture says corn pollination has begun in the state, and farmers are reporting the first tassels and silked ear shoots.  About 84 percent of the state’s corn crop rated in good or excellent condition as of Sunday. That’s better than the average of 76 percent good or excellent at this time of year.  But the USDA says the wheat harvest in Nebraska is about 10 days behind the average and only about 10 percent complete.
