**5. Sewan in alternate land use system**

Alternate land use system is appropriate in areas where subsistence farming is practiced in fragile ecosystems and it poses more potentiality and flexibility in land use than the traditional crop production systems. An ideal system for dry land areas should have a judicious mix of crops, trees and grasses only then the natural resources will be judiciously utilized and returns maximized without any detrimental effect to environment [43]. Different alternate land use systems have classified in arid environments *viz.* Horti-Pasture system, Silvi-Pasture system, Agro-Forestry system, Agri-Pasture system, Agri-Horticultural system, Horti-Silvipasture and Agri-silviculture. Out of them, Agri-Pastoral system, Horti-Pastoral system and Silvi-Pastoral system are found very effective systems in which sewan grass use as alternate crop or grass to give maximum benefits (**Table 5**).
