LINCOLN, Neb. (AP) – The University of Nebraska will present its Regents Medal in honor of the late Robert Daugherty, the Omaha man who helped fund the Water for Food Institute.  The university’s most prestigious award will be given Friday to Daugherty’s family. The founder of irrigation company Valmont Industries died in November at age 88.  Last year, Daugherty gave the university $50 million to establish the global Water for Food Institute.  Board of regents chairman Bob Whitehouse says Daugherty’s donation has allowed the university to take the lead in developing ways to use water efficiently for farming.  The Regents Medal was established in 2006 to recognize individuals who contribute to the university’s mission.
