To study the effects of several agronomic practices on corn yield in western Nebraska, a strip trial was conducted at the Henry J. Stumpf International Wheat Center at Grant during the 2018 and 2019 growing seasons.
Spray quality refers to the Internationally Standardized Droplet Size Classification (ASABE S572.1). In this standard, the droplet size spectrum produced by a nozzle is classified as extremely fine, very fine, fine, medium, coarse, very coarse, extremely coarse, and ultra coarse, which describes the spray coverage and spray drift associated with the droplet size.
Grain sorghum variety testing was conducted at the Henry J. Stumpf International Wheat Center near Grant this year. The trial of 24 grain sorghum varieties also evaluated the effects of row spacing, comparing 15- and 30-inch rows.
Ideal temperatures, good moisture, and low disease pressure were the perfect conditions to achieve high winter wheat yields across much of southwest, west central, and the Panhandle of Nebraska with several counties averaging over 100 bu/ac.
Due to the late wheat harvest throughout western Nebraska, weeds growing in unharvested fields grew much longer than usual. In some fields weeds matured and produced seed. These weed control measures and residue management will be particularly important for the next wheat crop.
As the crop season progresses, questions about dicamba off-target injury in soybean, broadleaf crops, and trees are increasing in Nebraska. If you suspect off-target injury in one of your fields, here's a reminder of what to do.
