Seeding Rate & Minimum Stands

Seeding Rate

Seed winter wheat at 900,000 to 1,000,000 viable seeds per acre (about 70 lbs per acre). Increase seeding rate by 150,000 to 200,000 seeds per acre if seeding late or poor seedbed conditions.  Seeding depth of 1 to 1 1/2 inches is optimal for quick emergence.  Seeding depths of less than one inch increase likelihood of winter kill.

Minimum Stands

Optimum plant stands are 21 to 23 plants per square foot based on a recommended seeding rate. Winter wheat stands of 12 to 15 plants per square foot are more than adequate for successful production.  When winter wheat plants are at 30 to 40% of original stand or 5 to 11 plants per square foot, replanting should be considered. 

Do not discount plants where leaf burn has occurred.  Often, small seedlings will take some time before an accurate assessment can be made.

The addition of nitrogen fertilizer may help poor stands. If nitrogen was mostly fall applied, add 30 lbs. per acre to enhance tillering.
