Abstract
Increased ethanol production may result in excessive dried distillers grains (DDGs) that could be utilized as a fertilizersource for corn (Zea mays L.). Research was conducted to evaluate the effects of 1) DDG rates on weed suppression,changes in soil properties, and differences in grain yield and quality and 2) DDGs, polymer-coated urea (PCU), andanhydrous ammonia (AA) fertilizer sources on grain yield and quality. DDGs had a total N-P-K composition of38.2-6.9-11.5 g kg-1, respectively. There was no corn injury, common cocklebur or jimsonweed control with DDG ratesup to 3600 kg ha-1. Corn grain yield increased 1.41 and 1.56 kg ha-1 for every kg ha-1 of DDGs applied in medium andhigh yield environments, respectively. Grain yield was ranked non-treated control < DDGs < AA = PCU whenfertilizers were applied at N equivalent rate of 140 kg ha-1 in medium and high yield environments.
