The research program addresses crop production challenges specific to the region. These include cultural and management practices for both dryland and irrigated crop production. Specific emphasis is placed on soil fertility and nutrient management, dryland cropping systems (involving crop rotations and tillage practices), and limited irrigation research. The purpose of the research is to increase nutrient- and water-use efficiencies, improve producer profitability, and enhance soil quality and the environment. The station also participates in the statewide crop performance testing program for winter wheat, corn, grain sorghum, and sunflower. Researchers from other locations participate in cooperative research at Tribune involving evaluation of weed control methods and alternative dryland crops.
