Impact of Vam Inoculation on some Semi-Arid Tree Species

Abstract

Use of biofertilizer particularly VAM fungi has a great importance in forestry as it provides minerals, wide absorption area of root 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, root 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.
