Many growers today are not realizing the full yield potential of the Pioneer hybrids they are planting.Every Pioneer hybrid is evaluated in research for its performance up to 40,000 final plant population per acre.The optimum plant population per acre does vary by hybrid and yield environment but many will produce their optimum economic return at 34,000 plus final plant population.Studies on plant stand loss show that you can generally expect to lose 7% of your seed drop.That means that if you are dropping 36,000 seeds per acre your final plant stands will generally run in the 33-34,000 per acre range.Todays hybrids have the bred in stress tolerance to perform better at these populations due to their improved drought tolerance,silking strength and leaf disease resistance.
