Yields can be partially recovered when planting late
The study indicated that although yield potential is reduced by planting wheat after the optimum window for a given area, some of the potential yield can be recovered by increasing the seeding rate. In the fall of 2008 and 2009 when wheat was planted on Sept. 26 and Oct. 10, wheat yields were similar across the planting rates of 60, 90, 120, and 150 pounds per acre. However, when wheat was planted on Oct. 24 or Nov. 7, the lowest yield for that date was observed with the 60 pounds per acre seeding rate and a stair-step increase was observed with the 90, 120, and 150 pounds per acre seeding rates on these dates.
“But it is important to note, that although the 150 pounds per acre seeding rate on Oct. 24 and Nov. 7 had the highest yield for that date, that yield was not as much as wheat planted during the more optimum planting period for the area of Sept. 26 to Oct. 10,” Olson said.
“We’re planning to plant again for this next year,” he added. “Hopefully, we’ll have good moisture.”
