ABSTRACT
The agricultural sustainability could be viewed as maximum plant production with minimum soil loss. The
establishment of plant cover is the most important step in restoration of degraded areas. Plant and soil health are
dependent upon the interactions of biological, physical, and chemical components of the soil. Arbuscular
mycorrhizal (AM) fungi form endomycorrhizal associations with the root of 70-90% of all known vascular plant
species. The symbiotic relationship between roots and Arbuscular Mycorrhiza (AM) fungi may also benefit the
formation of soil structure and plant growth. This study was conducted to determine the effects of three different
indigenous AM fungi i.e. Glomus mosseae, Glomus fasciculatum and Gigaspora decipiens either single and in
combination inoculation with pearl millet, effect on soil quality grown in the pot experiment under barren soil
conditions. Pot trial results showed that AM fungi treated plants barren soil improved their chemical properties as
compared to control (non-mycorrhizal) treatments.

I. INTRODUCTION
Agricultural land degradation is an increasing worldwide
problem that leads to poor soil health. Natural
regeneration and revegetation are very slow in a highly
disturbed barren soil. Present world demands the
production of high quality food in a most sustainable
way causing least damage possible to the ecosystem [1].
In soil, the natural microbial populations are activated to
grow around developing plant roots, giving rise to the
so-called „rhizosphere‟. Microorganisms are most
abundant members of the soil biota. The soil organisms
that develop beneficial symbiotic relationships with
plants roots and contribute to plant growth are called
mycorrhizal fungi. The most common and top known of
these relations are the Vesicular Arbuscular Mycorrhiza
(VAM) fungi [2]. Arbuscular mycorrhizal fungi
comprise intra- and extraradical structures. In
Glomeromycota, intraradical hyphae can penetrate the
outer cell wall of root and grow between or inside of the
root cell wall and plasma membrane where they develop
the intraradical structures, arbuscules and vesicles. The
extra radical structures are hyphae and spores that
develop outside of the roots in the soil [3]. The hyphae
grow within the plant root and extend out into the
surrounding soil acting as an extension of the root
system. This relationship greatly increases the
absorptive surface area of the root system and with the
help of the fungus; the plant is able to obtain mineral
nutrients from the soil [4]. In return the plant provides
carbohydrates and other nutrients to the fungus. The
benefits of glomalin is, in increasing aggregate stability
which leads to better soil structure and in turn leads to
increase water holding capacity of soil and thus overall
improve soil quality and better plant production [5, 6].
Therefore, the reason of the present study was to
investigate the effect of AM fungal species Glomus
mosseae, Glomus fasciculatum and Gigaspora decipiens
on plant growth and in changes in soil chemical
properties after pot experiment with pearl millet crop
subjected to barren soil conditions.
