“From the Ohio Agronomy Guide.” The optimum seeding rate is 1.2 to 1.6 million seeds per acre (18 to 24 seeds per foot of 7.5-inch row when planting during the two weeks following the fly-safe date). For the Maumee Area the Fly Free Dates are 9/22 for Williams, Fulton, Lucas; 9/23 for Defiance, Henry, Wood; 9/24 for Paulding; 9/25 for Putnam, Hancock and 9/26 for VanWert, Allen.
During the third and fourth week after the fly-safe date, plant 1.6 to 2.0 million seeds per acre (24 to 30 seeds per foot of row). Do not plant faster than the speed at which the drill was calibrated. Dates to increase seed rate to compensate for lower tiller are after October 6th in the northern part of the area and October 10. At this time (10/14) all wheat should be planted at an increased seeding rate.
The number of seeds per pound and germination rates are critical factors that need to be known before a proper seeding rate can be determined and the drill calibrated. This information should be listed on the bag of seed. The information in Tables 6-2 and 6-3 can be used to accurately calibrate grain drills.
