Research by the late Gail Wicks concluded that 3 inches of water were saved in the soil profile when weeds were controlled in a timely manner after the winter wheat harvest. Each inch of soil water increases the yield of corn or grain sorghum by approximately 12 bushels.
Volunteer wheat can provide the summer "green bridge" for the disease wheat streak mosaic and other virus diseases. This almost always occurs as a result of wheat seed shattered from heads during hail storms.
The COVID-19 pandemic is putting limits on public face-to-face programs, but Nebraska Extension will sponsor a variety of events in mid-June to share updates on the wheat variety trials and crop and livestock research conducted by University of Nebraska-Lincoln in western Nebraska.
Some producers are concerned with the condition of their winter wheat fields this spring. At the time of seeding last fall, some areas were dry and under no-till conditions it was difficult if not impossible to seed at the recommended seeding depth.
Beginning in the 1970’s winter wheat was included in Ecofarming rotations with no-till corn or grain sorghum and summer fallow as a means to capture and maintain soil water through snow retention, increased infiltration, reduced evaporation, and weed control with herbicides instead of tillage.
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.
