167 Summer Grazer

Summer seeded mix where the focus is quick tonnage and over – biomass production

• SF 167 needs to be plantedin the summer/late summer, taking advantage of warm season species in the mix
• Tolerates a wide range of conditions – poor soil, low pH, hot and extremely droughty environments
• Conventional sorghum x sudangrass offers increased tonnage potential in grazing systems
• Formulated to maximize biomass growth when planted early

Termination: Any frost will terminate sorghum x sudangrass and sunn hemp. Small sunn hemp (less than 3-4’) can be effectively controlled with light rates of glyphosate. Taller plants require higher rates and equipment to allow for proper coverage. Radish will terminate with multiple nights in the teens. If radish over winter, glyphosate and 2,4-D provide effective

Considerations: Sunn hemp will flower when temperatures allow across the country, but will only produce seed in the deep south (below 28 degree north latitude – think Orlando, FL and Corpus Christi, TX ). Sunn hemp is known to contain toxic alkaloids harmful to grazing animals, present in the seeds only. Sunn hemp may not be ideal in 100% of no-till systems as any leftover residue can be tough to plant through the following spring . Sorghum x sudangrass presents the opportunity for prussic acid toxicity, especially after fall frosts. To maximize forage production, nitrogen applications are recommended. However, those same fertility supplements can pose an increased
threat of elevated nitrates in sorghum x sudangrass after plants are stressed.

Seeding Rate:

25-30 lbs/acre
