Arkansas Rice Verification Update: N-STaR* Recs Show Shifting Needs
Closing commodity reports from the
Arkansas Farm Bureau Commodity Staff.
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.
