The development of water and weed management technologies and practices for irrigated agriculture in water deficit areas that use water efficiently, improve agricultural productivity, sustainability and reduce negative environmental impacts.


  • Conduct a 5 yr. field trial with a 4 crop rotation (Wheat, Sunflower, Corn, Dry Beans) under 2 tillage practices (conventional, minimum) and 5 levels of irrigation (rain fed to full irrigation).

  • Schedule irrigations based on weather, crop responses, and crop models

  • Develop water production functions for each crop ("Crop per Drop"), and better understanding of crop stress responses.

  • Develop weed management practices under limited irrigation conditions.

  • Determine the economic returns for each level of irrigation and how to optimally allocate a limited water supply.
