Corn silking around the state is 72%, and corn in the dough stage if 5%. That is behind 85% silking average and 11% dough stage rates, according to the latest USDA crop update report released on Monday.
Overall, pollination is going well says Eric Miller with DuPont Pioneer, “The corn that was planted in early May has finished pollination and is well into brown silk. While the corn planted in late May and early June is just beginning pollination, and conditions are good.” He said the rain that moved across much of Central and Eastern Indiana on Sunday will do much to help the crop.
Miller, who covers East Central Indiana, says the lack of growing degree units and the cooler and cloudier conditions have had an impact on crop development and will likely impact further performance, “We are seeing some large tips on the end of some ears that did not get pollinated, and we attribute that to the lack of growing degree days and sunshine.” He added, if August can produce some warm but not hot weather conditions, then that will help with kernel set.
The excessive rain in June and July has had an impact on nitrogen levels in fields around the state. Miller says this shortage will become more noticeable as grain fill begins, “A lot of fields have a nitrogen deficiency, and there is a great deal of nitrogen that the plant needs during grain fill. So a lack of nitrogen will have an impact on test weight and yield.”
As for soybeans, Miller says the past few weeks have seen an improvement in the condition of the crop on the eastern side of the state, “The yellow looking beans we had a few weeks ago have improved, and most soybeans are flowering.” Statewide, 59% of the soybeans are flowering with 36% setting pods, but again are about 2 weeks behind average.
He told HAT disease issues for both corn and soybeans will be the next big issue for growers. Listen to the complete report on the crops page.
