Rice Research Verification Program Update – May 7, 2012

The much-needed rain across South Arkansas Monday was a tremendous help for emerging rice stands.  Five verification fields are at early tiller stage.  Postemergence herbicides are being applied.  Five fields, Arkansas 1, Arkansas 2, Chicot 1, Chicot 2 and Lee Counties will receive pre-flood nitrogen as soon as the ground dries.  N-STaR* samples have been determined.  Several fields have reduced N rate while a few have a slight increase.  The goal for N-STaR* is to get the RIGHT N rate for the field.

The area finally received 2.6” rainfall. First decent rain since April 10th. Ouachita River rose enough for pumping back up the field. We will have to wait and see just how much damage due to lack of water. Stink bugs running 4 per 10 sweeps.

ClayXP 753Hard DoughThe well was turned off last week and the field should be drained and harvested within the next few weeks. Very little noticeable difference is being observed in maturity on the area where the Newpath drift affected the rice early season.
ConwayXP 753Hard Dough/MatureThe field was drained a few weeks ago and should be harvested within the next few weeks. Sodium Chlorate will be recommended on the field due to the extremely later maturing volunteer rice.
