Almum grass

Almum grass (Sorghum x almum) is a productive perennial hybrid belonging to the Poaceae family. Known as a natural hybrid between grain sorghum and Johnsongrass, this forage crop is prized for its exceptional biomass production, rapid regrowth after grazing or harvesting, and its ability to thrive in demanding environmental conditions.

Originally identified in Argentina, Almum grass has been introduced to various regions across the globe, including Australia and Southern Africa. It is primarily adapted to subtropical and warm-temperate climates, where it serves as a reliable source of forage during the hot summer months when other cool-season grasses fail to produce sufficient growth.

Botanically, this grass is a robust plant with stout, leafy stems that can grow quite tall. Its root system is extensive and includes rhizomes, which allow the plant to perennialize and survive dormant periods. The leaves are broad and succulent, contributing to a high leaf-to-stem ratio, which is essential for maintaining forage quality under intensive management.

Cultivation requirements for Almum grass include well-drained soils and high soil temperatures for successful germination. It is highly drought-tolerant, making it an excellent candidate for regions with limited rainfall. Agronomic management involves strategic nitrogen application to maximize biomass yields and regular cutting schedules to prevent the plants from becoming overly fibrous and woody.

In terms of agricultural use, Almum grass is utilized for silage production, haymaking, and direct grazing. While it offers excellent nutritional value for livestock, farmers must be aware of potential nitrate or prussic acid accumulation, especially under stress conditions. Common pests include aphids and mites, while fungal diseases can appear in humid environments, necessitating proper field rotation and density management.

• Exceptional drought resistance and heat tolerance
• Multi-cut potential throughout the growing season
• High biomass yield for silage and hay
• Perennial growth habit reducing replanting costs
• Good adaptation to a variety of soil types
