Acroceras macrum (Nile grass, Nyl grass) is a species of perennial grass native to Africa, which is often cultivated extensively as pasture, silage, and hay. It is palatable and nutritious for animal feed. It has been studied in breeding programs and it has been introduced to Australia and South America for cultivation. Wild Nile grass grows well in flooded, moist, and humid conditions and does not do well in periods of drought. It prefers acidic soils. It produces seeds but is usually propagated using cuttings of the rhizomes.
