Insight into the Role of Arbuscular Mycorrhizal Fungi in Sustainable Agriculture

Abstract

Sustainable agriculture plays a vital role in agroecosystems and reduces adverse effects on the environment by utilizing the various natural processes. Optimum soil fertility is an essential goal to be achieved in sustainable agriculture system. The presence of benefi cial microorganisms in the rhizospheric region and their activities are the main focal point which makes dynamic resources available to plants and conserve soil fertility. Majority of the agricultural and horticultural crops are associated with common soil fungi, the arbuscular mycorrhizal (AM) fungi. These fungi are crucial for plant health and fi tness as they increase the effi ciencies of the plant root systems. The hyphae of these fungi originating from roots grow into the soil and absorb nutrients especially phosphorus and deliver it to the roots. They also play a crucial role in imparting tolerance to plants against various stresses as well as modifying soil structure. Nevertheless, several agricultural practices involved in crop production can infl uence both AM formation and function. Consequently, AM fungal introductions or changes in crop management practices that enhance the proliferation, diversity and function of native AM fungi become essential. Optimization of agronomic practices that sustain maximum AM fungal presence and activity would enable to achieve increased plant production in sustainable agriculture.

Enhancement of Manihot esculenta Crantz (Cassava) Tolerance to Salt and Drought Stress Using Arbuscular Mycorrhizal Fungi (Glomus Mosseae (T. H. Nicosia & Gerd) Gerd. &Trappe)

“…Apart from daily watering, plants treated with AMF were observed to grow better with a higher number of leaves. This finding is in tandem with the report of Oyetunjiet al 2007;Priyadharsini and Muthukumar, 2015 who reported that mycorrhizal association is capable of ameliorating all forms of stress and aid the formation of better vegetation in plants. However, the loss of leaves by both inoculated and non-inoculated plants could be due to leaf aging and mechanism for water conservation since the higher the number of leaves, the higher the rate of transpiration.…”

Effect of Inoculation with Arbuscular Mycorrhizal Fungi on Selected Spring Wheat Lines

“…Arbuscular mycorrhizal fungi interact at the root-soil interface in a coordinated manner. Their hyphae absorb and translocate water and nutrients from the soil to the plant to increase its growth and development (Dwivedi, 2015;Priyadharsini & Muthukumar, 2015). Wheat is colonized by mycorrhizae, but colonization depends on AMF strains and soil conditions.…”
