Missouri 2005 Corn Performance Tests
There are five locations in the northern region of Missouri for non-irrigated corn tests. They are located in counties where a significant number of acres of corn are grown according to the Missouri Agricultural Statistics Service. Cultural practices vary from location to location, but tend to reflect those followed by farmers in the area. Planting dates ranged from April 21 to May 5 with soil conditions being very good at all locations. Below normal rainfall and above normal temperatures during grain fill did not seem to adversely affect yields. An outbreak of spider mites in early August at LaGrange prompted an aerial application of Lorsban to control the pests. Woods Flying Service of Memphis, MO was hired to fly on the insecticide. There was severe lodging at the LaGrange site from a strong storm in August. Yields were very good at all northern locations this year, although there was some disease and insect pressure present. Climatological information for the growing season for North Missouri (April 1 – August 31) is summarized below.
Average temperature = 69.2 degrees, 2.5 degrees above normal
