Corn‐Foxtail Competition Under Various Production Conditions¹

Abstract

Synopsis Corn yield reductions resulting from mature foxtail infestations averaged 20, 14, and 10 bushels per acre, respectively, with applications of 0, 70, and 140 pounds of elemental nitrogen per acre. Growth and yield of foxtail were depressed with higher corn plant populations. The roles of soil nitrogen, soil moisture, and corn plant populations are discussed. Possible effects of uncontrolled environmental and biological factors are recognized.
