Grain Sorghum Demonstration Tours Slated for August 8th and 9th
Wed, 31 Jul 2013 11:58:59 CDT
Northwest Oklahoma grain sorghum producers have a chance to look at the Oklahoma Cooperative Extension Service demonstration sites for hybrid evaluation, grain sorghum weed control efforts and listen to a discussion of stalk utilization. Three different sites will be reviewed across the area during August 8th and 9th.
The first tour stop will be in Alfalfa County beginning at 10 a.m. August 8th. The location will be from Cherokee, 2 miles west on Fish Street to County Road 590. At that intersection, turn south and the plots will be on the west side of the road just past the bridge.
The second tour stop will be in Kay County, northeast of Blackwell. These plots are located between R and S roads on Earth Street. Earth Street is just one mile north of Peckham Road. This tour stop will begin at 7 p.m. on the 8th. Producers at this stop get the same information presented at Cherokee, but a few additional comments will be made about the fertility demonstrations located here. OCES is evaluating some additional nitrogen use efficiency treatments at this site.
The final tour stop will be on Friday, August 9th beginning at 10 a.m. This tour location is in Major County, just 1 mile north of the Homestead Elevators and turn east about ¼ of a mile. The same discussion will be presented at this location.
Grain Sorghum seed companies have entered several of their hybrids for evaluation and discussion of their merits for this area. Producers can hear the agronomic benefits and where their particular hybrid fit in the production systems demonstrated at the sites.
Also providing comments on the hybrids will be OCES Agronomist, Rick Kochenower. Kochenower has been evaluating hybrids across Oklahoma and has some additional thought on where each of the hybrids should be placed for best performance. Along with the hybrid discussion, Kochenower will review the growing season and his expectations given the year that has been presented to growers. Recent rainfall has been very beneficial and producers are facing some decisions on fertility and weed control that they may not have anticipated. Insect management may also be important to producers as they finish out the production year.
In the demonstration plots, some herbicide work utilizing some of the tank mix options for grain sorghum producers will be demonstrated. The use of atrazine by itself will be analyzed as will the use of metalochlor by itself, the combination of atrazine plus metalochlor, and the use of atrazine, metalochlor and mesotrione. All these products are labeled for use in grain sorghum, but have separate modes of action to help control weeds. Additional comments will be made to help double crop options for weed control if needed to bring those crops to market. This discussion will be led by Roger Don Gribble, OCES NW Area Agronomist.
The final discussion at the demonstration sites will address the utilization of the grain sorghum stalks after harvest. Interim Area Animal Scientist, Steve Smith will review nutritional values for the stalks and utilization of the stalks as a standing crop or as baled forage. He will also review some of the dangers in utilizing the stalks as forage
