South Arkansas: The warm weather has rice moving in the fast lane. The Pulaski County field has gates installed and was the last field to be flooded. All verification fields except Pulaski are progressing well and are at internode elongation (IE). Mid-season nitrogen has gone out on the Lafayette County field. The Clark, Desha and Pulaski County fields are approaching mid-season this week according to the DD-50. GreenSeeker technology is being used to determine if mid-season applications are necessary. The Jefferson County row-water field has received its 3rd nitrogen application. The Prairie County field is approaching early boot stage.
North Arkansas: Fields are rapidly entering reproductive stage, Conway County being the first to reach green ring (beginning internode elongation) with St.Francis and Woodruff following closely. DD50 predicts that all other program fields except Randolph will reach green ring by next report. All fields are being checked with GreenSeeker technology to evaluate nitrogen needs at mid-season using the standard starting point of green ring plus 21 days (21 days since pre-flood nitrogen incorporation).
