Guinea grass (Megathyrsus maximus )/Panicum maximum

Native to tropical Africa and is now widely naturalized in the tropics. It is naturally found in open grasslands, woodland and shady places within 16.3°N and 28.7°S.Guinea grass is a large tufted, fast-growing perennial grass. It has a broad morphological and agronomic variability, ranging in height from 0.5 to 3.5 m, with stems of 5 mm to 10 mm diameter. There are two main types: a tall/medium tussock type, taller than 1.5 m at flowering, and a short tussock type . The root is a short creeping rhizome; culms are erect, hirsute at the nodes. Leaves are blade-shaped, glabrous to pubescent up to 35 mm broad. Inflorescence is a panicle, 15 to 50 cm long. Spikelets are 3-4 mm green to purple .


Giunea grass is a drought tolerant leafy high quality feed readily eaten by all stock. It becomes stemmy if not cut or grazed frequently.



Guinea grass is a fast growing, bulky grass that helps prevention of soil erosion since it provides rapid ground cover . While it spreads slowly when it is well managed, Guinea grass can spread very fast and become a weed in ungrazed areas where soil disturbance has occurred. It is a major weed in sugarcane fields since it grows well in shaded conditions.
