Abstract

A limited irrigation study involving four cropping systems and evaluating four crop rotations was initiated in 2012 at the Southwest Research-Extension Center near Tribune, KS. The cropping systems were two annual systems (continuous corn [C-C] and continuous grain sorghum [GS-GS]) and two 2-year systems (corn-grain sorghum [C-GS] and corn-winter wheat [C-W]). In 2019, corn yields were similar for all rotations, although averaged across the past 7 years, corn yields were greater following wheat than following corn. There were no significant differences in grain sorghum yields in 2019, which was similar to the multi-year average. Wheat yields were greater than the multi-year average.

Keywords: Corn, grain sorghum, winter wheat, deficit irrigation, irrigated crop rotations
