ABSTRACT
Grassland covers 27% of the world’s total land area and 71% of the world agricultural area (FAO). Grassland produces large amount of forages for ruminants, maintains soil fertility, protects and conserves soil and water resources, harbors stock of carbon in terrestrial ecosystems, creates a habitat for wildlife, and provides recreational spaces for sport and leisure while contributing to the general benefi ts at the same time maintaining sustainable economic outputs. In addition to food and environment, grassland biomass can be used as a renewable source of energy. Besides being used for grassland, some forage grasses are grown specifi cally for turf or amenity purposes on sports fi elds, golf courses, parks, lawns and roadsides. Turf grasses contribute considerably to the environment by adding beauty to the surroundings, providing a safe playing surface for sports and recreation and preventing erosion.
