    Rice Research Verification Program Update

    May 14, 2012

    Several Rice Research Verification fields are going to flood this week.  Arkansas 1, Chicot 1 and Chicot 2 are now being flooded.  Much needed postemergence herbicides are being applied on some fields.  The N-STaR* nitrogen rates have been determined.  Several fields have reduced N rates while a few have a slight increase.  The purpose for N-STaR* is to get the RIGHT N rate for the field.
