   Better ways to manage weeds, soil fertility and learning the latest in variety breeding and testing are part of the wide-ranging agenda at the July 18 Row Crops Field Day at the Rohwer Research Station.  
   This event, the first of the Arkansas Agricultural Experiment Station’s row crop field days, will feature a lineup of University of Arkansas System Division of Agriculture experts talking about production in corn, cotton, soybeans, and rice.
   "Our field day is all about methods to control disease, insect populations, anything that’s pertinent to our agriculture production system,” said Larry Earnest, manager of the Rohwer Research Station. “This is an opportunity for producers to see what our researchers have found in their work.” 
   Jean-Francois Meullenet, director of the Agricultural Experiment Station, will be this year’s lunchtime keynote speaker.
   There is no cost to attend and registration opens at 7:30 a.m. 
   There are four sets of tours, one for cotton and corn; a second for soybeans, a third tour for rice and a fourth tour, which will give a behind-the-scenes peek at the station’s research equipment. 
   Tours will leave at 9 a.m. and 10:30 a.m. Participants should only select two tours. A free lunch will be catered by Country Catfish Cooking.
