Synopsis Corn yield reductions resulting from mature foxtail infestations averaged 14, 10 and 5 bushels per acre respectively, with applications of 0, 70 and 140 pounds of elemental nitrogen per acre. Corn yields were increased 2 to 3 times more than foxtail by the fertilizer applications. Possible effects of uncontrolled factors are recognized.
