Rio Grande Basin Initiative

2005-06 Deliverables

Task 4 Extension
Principal Investigator(s): Thomas Gerik, Monty Dozier

  1. Document crop water use, crop water use efficiency, and crop yield relationships for current using current cropping and irrigation practices for the prevailing management (i.e., single crop per year, furrow irrigation and conventional tillage) and alternative systems (double crop, furrow or buried drip irrigation and conservation tillage). (From Activities 1, 2, and 3).
  2. Identify alternative cropping and/or irrigation management strategies that can reduce on-farm irrigation water use by 20% (From Activities 1, 2, 3, 4).
  3. Conduct two to three educational events related to use of CroPMan to manage water use and salinity in crop production systems of the Rio Grande Valley.
  4. Develop and deliver a hands-on, spreadsheet-based decision tool to assess the risk of various crop, soil, and irrigation practices, as well as quantify economic trade-offs in allocating soil and water resources to various cropping alternatives.
