Grain Sorghum Production in Arkansas
Response to the Challenges of 2006

Producers harvested an average of 80 bushels/acre from 66,000 acres in 2005. The 5-year average yield was also 80 bushels/acre. Dryland production systems account for approximately 50% of our acreage.

Management Practices to Maximize Profit

Early Planting - early planting is very critical, especially for dryland fields. Typically early planted grain sorghum will be able to make a crop before hot dry weather hits in July. Later planted grain sorghum will likely need an insecticide application to control sorghum midge at flowering
Proper Plant Populations - Plant populations greater than recommended will increase water consumption and likely reducing yields on dryland fields
Proper Herbicide Programs - Don’t apply a full rate of atrazine immediately after planting or crop injury could result
Balanced Fertility Program - get soil sample for current nutrient levels
Select High Yielding Hybrids - High yields with good standability
Irrigation Management - Irrigations at the boot and flowering stage often produces yields comparable to full irrigation.
Follow Proper Crop Rotation - avoid grain sorghum following grain sorghum rotation due to increased levels of anthracnose
