Objectifs
Objectives : 1. Evaluate the water use efficiency, soil sustainability, and profitability of dryland crop production practices for western North Dakota. 2. Investigate water management and nutrient management techniques for sprinkler irrigation in the MonDak region. Outputs : The information will be obtained by field trials on dryland and irrigated fields. Results will be reported orally at annual field days and local and regional conferences and by publication in annual research update reports, popular magazine articles, extension bulletins, and professional journals.

Descriptif
Replicated and randomized field experiments will be located on dryland and irrigated fields. Experiments will contain a series of treatments including a check treatment for comparison. The irrigated studies will utilize linear-move, overhead-sprinkler irrigation systems with variable rate irrigation control systems. Crop performance will be evaluated based on grain yield, test weight, and grain protein or seed oil content. Crop water use will be determined by weekly measurements of soil water content during the growing season. Soil nitrogen, phosphorus, pH, and organic matter will be determined annually with other soil nutrients determined less frequently. In some studies, additional performance characteristics may be measured such as above-ground biomass, market quality factors, nutrient use, pest problems, and equipment requirements. Some studies will include comparisons of different crop rotations, tillage systems, or fertilizer rates. Economic analysis of the trial results will be performed by the station’s extension specialist
