Use of biofertilizer particularly VAM fungi has a great importance in forestry as it provides minerals, wide absorption area of ischolar_main zone, water uptake and tolerance to water stress conditions etc. Rajasthan covers about 61% of the geographical area of the total desert area of the country. In these harsh conditions, VAM fungi can play a significant role in survival of plants. In the present study some economically important tree species of Jaipur region namely Cordia myxa, Artocarpus integrifolia. Dalbergia sissoo, Pongamia pinnata, Mangifera indica and Alestronia sp. Were seleded for the study. VAM inoculated seedlings of above tree species performed better in term of shoot height, ischolar_main height, biomass and percentage of colonization. The shoot height inerease was maximum (32.2%) in A, integrifolia and minimum (11.2%) in Mangifera indica. The other parameters were also found better then uninoculateel plants.- Role of Arbuscular Mycorrhiza Strains on Biomass Production and P, Cu, Zn Uptake in Prosopis cineraria

Prosopis cineraria was grown in a green house in a low phosphorus (4 mg kg-1 Olsen's P) soil (Typic Camborthid) under arid environment inoculated with alone or mixed AM fungi either indigenous or from outside sources. Uptake of relatively immobile soil nutrients (P, Zn, Cu) as affected by different AM fungi was also studied. In general, significant and positive response of plant height, ischolar_main and shoot biomass, ischolar_main colonization and AM fungal population was observed in inoculated plants as compared to control. Inoculated plants had significantly higher P, Zn and Cu concentration as well as upto three times more total uptake. Mycorrhizal dependency to P. cineraria varied between 13.76 and 56.28%, which was more to Glomus aggregatum. In general, G. aggregatum was found to be the most efficient AM species for growth and nutrition of P. cineraria plant.Keywords

Occurrence of VAM fungi is ubiquitous and are found in most ecosystems including arid- and semi-arid deserts. A survey for collection of ischolar_mains and rhizosphere soil samples of neem from various Forest Department nurseries and plantations in arid zone of Rajasthan revealed variation in per cent ischolar_main infection and number of VAM propagules in the rhizosphere soil samples. It has been observed that mean number of VAM fungal propagules and per cent ischolar_main infection were greater in plantation samples than in nursery samples. Different VAM fungi have been isolated, of which the genus Glomus is dominant with an exception of Sclerocystis in plantations. Among the Glomus spp., G. fasciculatum is the most predominant one in both nursery and plantation. The significance of these findings is discussed.- Is Ganga the Longest River in the Ganga Basin, India?
