Characterizing Irrigation Water Requirements for Rice Production from the Arkansas Rice Research Verification ProgramPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: 2012 Dallas, Texas, July 29 - August 1, 2012 121337151.(doi:10.13031/2013.42266)Authors: Chris G Henry, Earl Vories, Merle (or initial) Anders, Michele Reba, Chuck ( Wilson, Sarah Hirsh Keywords: Rice, irrigation, multiple inlet, contour levee, zero grade, straight levee This study investigated rice irrigation water use in the University of Arkansas Rice Research Verification Program between the years of 2003 and 2011. Irrigation water use averaged 747 mm (29.4 inches) over the eight years. A significant 40% water savings was reported for rice grown under a zero grade irrigation system (482 mm or 19.0 inches) compared to contour and straight levee systems. No differences in water use were found comparing contour levees (812 mm or 31.9 inches) and straight levees (815 mm or 32.0 inches). Arkansas producers implementing the multiple inlet water delivery practice on contour levee or straight levee systems, irrespective of soil type, did not realize a water savings. These results are in contrast to those in earlier studies and suggest that an educational effort may be helpful for those utilizing multiple inlet in Arkansas. (Download PDF) (Export to EndNotes)
