Napier grass

Cenchrus purpureus, synonym Pennisetum purpureum, also known as Napier grass, elephant grass or Uganda grass, is a species of perennial tropical grass native to African grasslands. It has low water and nutrient requirements, and therefore can make use of otherwise uncultivated lands.

Historically, this wild species has been used primarily for grazing, recently, however, it has been used as part of a push–pull agricultural pest management strategy. Napier grasses improve soil fertility, and protect arid land from soil erosion. It is also utilized for firebreaks, windbreaks, in paper pulp production and most recently to produce bio-oil, biogas and charcoal.
