Corn seeding rates and variable-rate seeding

Abstract

<p>The current demand for corn has generated a great deal of discussion this past winter of corn yields exceeding 300 bushels per acre. What management considerations should producers make when aiming for high yields? As corn hybrids have developed, the focus by scientists has been toward increasing stress tolerance of individual corn plants. Corn yield potential per plant has not increased over the past 50 years, but the amount of yield per acre has increased. Hybrids can tolerate their neighbors today better than ever and are therefore able to withstand higher plant densities while still producing an ear.</p>
