Sorghum is utilized for both grain and silage production in Georgia. It is drought-tolerant, with a well-developed root system. Although historically utilized in low-fertility fields, yields can be substantially higher if fertilized adequately.
Newer varieties are more tolerant of cool soils, and can be planted when soil temperatures reach 60°F. A second planting window, following wheat harvest is also commonly utilized.
Grain sorghum varieties differ in their time to maturity, but are generally require less time than corn. Silage and forage varieties can mature based on either growing degree days, like grain varieties, or on photoperiod. Forage and silage quality can be influenced by the ratio of stems to leaves, the presence of the brown mid-rib trait, and other characteristics.
Sugarcane aphid is a major pest, but varieties with increased resistance are becoming available. Sorghum does not contain biotech traits, but offers lower seed costs than some other crops.
We're working diligently to digitize older performance tests and will update this page throughout the process.
