To determine crop cultivars appropriate for dryland cropping systems and environments, and to assist in the development of superior germplasm for potential release as improved cultivars. To develop and participate in multi-disciplinary, collaborative and/or cooperative research efforts toward improved dryland cropping practices with other scientists in the Montana Agricultural Experiment Station, Extension Service and College of Agriculture. To evaluate differing seed and fertilizer placement configurations for dryland cropping systems and environments using the latest available plot-scale and field-scale air drill technology. To determine the effects of seed and embryo size relationships on seedling and mature plant performance with cereal grains grown under dryland cropping systems.

Cultivar performance will be evaluated under conditions specific to differing environments at selected locations within the north central Montana area. Computer-assisted mapping techniques will be utilized in selecting locations for off-station studies and extending application of resulting information to other similar environments. Wheat evaluations will include economic considerations on gross dollar return as affected by yield, protein, and market activity. Cooperative efforts will include co-investigative support directed toward integrated strategies for wheat stem sawfly management, manipulation of crop seed band width and population density for weed management, and site-specific crop management. The effects of cereal seed size will be evaluated as a component to seed and fertilizer placement research and variable rate technology investigations.
