<p dir="ltr">The USDA-Agricultural Research Service conducted a deficit irrigation and water productivity field trial for irrigated sunflower (<i>Helianthus annuus</i>) in northeastern Colorado in 2008 through 2016. Oil-type sunflower was irrigated at a wide range of amounts in a replicated field trial. This dataset from that field trial is composed of 5 Excel workbooks. The dataset includes measurements of irrigation amount, precipitation, soil water storage, and plant responses; daily estimates of crop evapotranspiration; and seasonal crop water use and crop yield data. Soil parameters, hourly and daily weather data and photo images are also provided. The dataset can be useful to develop and evaluate sunflower crop models under varying conditions and levels of water stress.</p>
