High-biomass, drought-tolerant forage for reliable feed all year
This technology is a set of improved Megathyrsus maximus (syn. Panicum maximum) forage grass cultivars for livestock feeding: Mombasa, Tanzania, and Massai. They are improved forage grasses developed to deliver high biomass yields (10–20 t DM/ha/year) under tropical conditions. Selected for drought tolerance (500–600 mm rainfall) and good nutritional quality (8–12% crude protein; 55–65% digestibility), they ensure reliable year-round feed supply. Established through seeding or splits in well-prepared seedbeds, these cultivars show rapid regrowth and strong persistence, while their deep root systems improve soil structure and reduce erosion, supporting sustainable livestock production systems.
This technology is pre-validated.
Adults 18 and over: Positive high
Engagement in livestock production, hay production and sale
Others: No impact
None
The poor: Positive medium
Forage for livestock
Under 18: Positive high
Engagement in hay production and sale
Women: Positive high
Engage in production with less time looking for forage, hay production, seedling production for sale
Climate adaptability: Highly adaptable
It works well where it is adapted in the tropical and sub-tropical environments
Farmer climate change readiness: Significant improvement
The forages are relatively drought tolerant and once established do not require to be planted every season. With good management can last 10 years before re-planting again
Biodiversity: Positive impact on biodiversity
It helps them grow and thrive as creates amenable micro-environment
Environmental health: Greatly improves environmental health
Prevents soil erosion through deep roots that also sequester carbon through roots turnover. Provides soil cover and promotes biodiversity
Soil quality: Does not affect soil health and fertility
Although the grasses take nutrients from the soil for good growth and biomass accumulation, manure accumulated by animals fed on the same can be ploughed back thus nutrient cycling which is desirable
Water use: Same amount of water used
Productivity water use efficiency would be high compared to most crops as the target use is the biomass
Seasonal Feed Shortages and Declining Livestock Productivity:
Climate Variability and Drought Stress:
Soil Degradation and Low Pasture Sustainability:
Megathyrsus maximus forage cultivars provide a practical and scalable solution for addressing seasonal feed shortages and improving livestock productivity across smallholder systems. By supplying high-yielding, drought-tolerant forage instead of relying on low-productivity natural pastures, these cultivars enable rapid, cost-effective expansion of climate-smart fodder production critical for stabilizing milk and meat yields and enhancing resilience to climate variability. The technology reduces feed scarcity, improves herd health, increases year-round forage availability, and supports sustainable land management through improved soil structure and erosion control. Megathyrsus maximus adoption aligns with development priorities such as inclusive livestock systems, climate-smart agriculture, women’s empowerment in farming, and private sector engagement in forage seed value chains.

The United Nations Sustainable Development Goals that are applicable to this technology.
Increased livestock productivity; increased incomes; income diversification
More animal source food (meat, milk) is available for humans
Creates opportunities for women and youth to participate in forage seed and forage value chains, while also reducing labor demands, especially for women.
Increases animal stocking rates and reduces environmental footprint per unit product (emission reductions, land sparing, carbon sequestration)
