Abstract :

Screening of AM fungi on plants growing on saline–alkali soil of south–west coastal of Kumta (Karnataka) was undertaken. Field experiments were conducted to know the species in this region after supplying various reclamative amendments. Results revealed that plant survival rate got improved by the amendments lead to decrease the saline– alkali soil stress condition like pH and soil concentration. The significant effect of amendments with inoculation of different AM fungi was determined on selected plants. The inoculation of efficient species like Glomus macrocarpum in plants enhanced their survival rates. Maximum plant survival was observed when Glomus species with PGPR and gypsum amend ments were grown in saline–alkaline soil. It can be concluded that Arbuscular mycorrhizal fungi with different phosphorous and potassium with PGPR on legume plants could ing reclamation of coastal sand dune soil on saline– alkaline affected soils. Therefore microbial component could play important role in revegetation of such ecosystems
