Three important leguminous plants Tamarindus indica L., Dalbergia sisso Roxb., Cassia nodosa Roxb., their ischolar_mains and soil samples were screened for their AM fungal association. Percentage of ischolar_main colonization and spore number of these plants were co related to each other. Higher spore number was recorded in Cassia nodusa Ham., during December and April compared to Tamarindus indica L., Dalbergia sisso Roxb in soil depth between 16-24 cm. On contrast to this per cent ischolar_main colonization significantly increased during April in Dalbergia sisso Roxb. , Tamarindus indica L., followed by Cassia nodosa Ham. The results revealed that both ischolar_main colonization sporulation declined from September to April in the examined tree species.Keywords

The effect of Glomus macrocarpum, Glomus fasciculatum and Azotobactor Proralea corylifolia L. was studied in sterilized soil. Compared to un-inoculated plants, chlorophyll content, height, weight, number and area of leaves of plant and weight were maximum in plants inoculated with G. macrocarpum, G. fasciculatum and Azotobactor or with G. macrocarpum and G. fasciculatum or with only G. macrocarpum, or G. fasciculatum. The levels of ischolar_main colonization was higher in all AM inoculated plants. There was significant increases in (3.96%) and P (0.21%) in the plant treated with a combination of Glomus macrocarpum, Glomus fasciculatum and Azotobactor. The results clearly indicated that compared to individual inoculation, AM fungal species with Azotobactor used in combinations were more beneficial for much improved growth of onion.Keywords

Indigenous arbuscular mycorrhizal (AM) fungus was isolated from rhizosphere soils of Pongamia pinnata. Young seedlings of P. pinnata inoculated with indigenous AMF Glomous fasciculatum showed significant growth and the plants introduced with Glomous mosseae did not show significant effect on growth. The dual inoculation with indigenous Glomous fasciculatum and introduced Glmous mosseae depicted growth response was much greater than the single inoculation. The tripartite system of indigenous and introduced VAM with Rhizobium phaseoli improved significant increase plant height, plant dry matter, nodulation number, N and P content of Pongamia pinnata over non-inoculated plants with either AMF or Rhizobium alone.Keywords

The Establishment Of Arbuscular Mycorrhiza (am) Fungi Was Recorded In Six Cultivated Crops. There Was A Seasonal Fluctuation Of Am Fungal Colonization In Root Bit And In Root Length On Jowar, Wheat, Safflower, Sugarcane, Pigeon Pea And Cotton. The Root Colonization And Amf Spore Numbers In Soil Samples Not Correlated With Each Other. Results Revealed That O.m. And E.c. Higher Or Lower Level Have No Influence On Colonization/Spore Number, On Contrary Higher P And N Concentration In Soil Reduced Root Colonization. It Shows, The Distribution Of Am Fungi Varied With Climate And Edaphic Environments As Well As Land Use Patterns Among Cultivated Crops.Keywords
