Effect of Inoculation of AM Fungi and Beneficial Microorganisms on Growth and Nutrient Uptake of<i> Eleusine coracana</i> (L.) Gaertn. (Finger Millet)

Abstract

Biofertilizers have been used as sources to improve plant nutrients in sustainable agriculture. Biofertilizers are low cost, renewable sources of plant nutrients which supplement chemical fertilizers. Mycorrhizal fungi are a major component of agricultural natural resources and members of kingdom fungi. The term 'mycorrhiza' is derived from Greek word which means 'fungus root'. Earthen pot experiments were carried out to study the inoculation effect of Arbuscular Mycorrhizal (AM) fungi (Glomus mossease), Azospirillium brasilense and PSB on plant height, dry weight of root and shoot, per cent root colonization, spore number, P and N uptake. Experimental pots were filled with 4 kegs of sterilized soil and maintained in green house at 25-30 °C temperature. Single inoculation of AM fungi and combined inoculation of AM fungi with Azospirillium brasilense or PSB was found to be moderately increased in all the growth parameters. However triple inoculation of AM fungi, Azospirillium brasilense and PSB was found to have highest growth parameters.

Effect of arbuscular mycorrhizal fungal inoculation on growth, and nutrient uptake of the two grass species, Leptochloa fusca (L.) Stapf and Sporobolus robustus Kunth, under greenhouse conditions

“…The present study shows the importance of AMF for the growth of L. fusca and S. robustus. Our findings agree with some studies which showed that AMF increased growth of different plant species (Ramakrishnan and Bhuvaneswari, 2014;Jan et al, 2014;Khakpour and Khara, 2012;Graham and Abbott, 2000). The root/shoot ratios of S. robustus changed significantly in response to F. mosseae and Mixed-AMF inoculation.…”

Effect of Chemical Fertilization, Biofertilizer and Thidiazuron on Growth and Yield of Anise (Pimpinella Anisum L.)

“…Also the data showed that the highest values of number of AM fungi spores (kg soil -1 ) were 3x10 4 and 3.2x10 4 in anise (Pimpinella anisum L.) roots obtained at inoculation of seeds with mixture of mycorrhizal and mycrobein at full dose of NPK in the first and second seasons, respectively. These results were in accordance with the finding of Ramakrishnan and Bhuvaneswari (2014) on Eleusine coracana (L.) Gaertn, they investigated that combined inoculation of AM Fungi with Azospirillium and Azotobacter significantly increased number of AM spores in soil . In this connection Edyta et al 2015 Table (3) showed the response of anise (Pimpinella anisum L.) to inoculation of seeds with biofertilizer and/or foliar plants with TDZ at half or full recommended doses of NPK.…”

A Review of Nutrient Management Studies Involving Finger Millet in the Semi-Arid Tropics of Asia and Africa

“…Research conducted on green manure is mainly focused on Gliricidia (a leguminous tree fodder) [8,44], which is rich in nutrients and decomposes rapidly [8]. Different bio-fertilizer products have been tested in finger millet such as Azotobacter [8,43,61,62], Azospirillium [61], phosphorus solubilizing bacteria (PSB) [8,62], and mycorrhizae fungi [61,63]. Based on a three year field study at Odisha, India, Dass et al [8] found that finger millet supplied with 50% of the recommended inorganic fertilizers, Gliricidia green leaf manure (2.5 t ha K2O); the combined organic treatment also increased soil moisture, organic C, and NPK content (Table 2).…”

“…Based on a three-year field experiment, Sridhara et al [43] found that application of Azotobacter, ZnSO4, and gypsum along with recommended NPK fertilizer enhanced the growth, yield parameters, yield and profitability of finger millet compared to the recommended fertilizer application alone (Table 2). Based on pot experiments with soil as the growing medium, Ramakrishnan and Bhuvaneswari [61] found that finger millet treated with Azospirillium + arbuscular mycorrhizal (AM) fungi + PSB increased plant growth and N, P uptake. Uptake of macro (N, P) and micronutrients (Zn, Cu) by plants was also enhanced when finger millet was treated with AM fungi compared to non-inoculated plants [63].…”
