Response of AM fungi at different levels of zinc on soil quality 12+

📙 The study was undertaken in greenhouse condition to find out the effects of inoculation with the strains of Arbuscular mycorrhizal fungi at different levels of zinc and its interactions in terms of plant height, fresh as well as dry weight of root and shoot, grain yield of finger millet, microbial population, per cent root colonization, available N, P and K and concentration of zinc and cadmium in soil after the crop harvest. Two factors interactions with four levels of AM fungal strains inoculation viz., uninoculated control (Mo), Gigaspora ACP-1 (M1), Glomus ACP-2 (M2) and Scutellospora ACP-2 (M3) and four levels of zinc application viz., 0, 150, 300 and 450 mg kg-1 soil were used. The zinc applied as zinc sulphate in the form of solution in the concerned pots having the treatment. Thus there were sixteen treatments in all .The details of each treatment have been given in table 3. The each treatment was replicated six times. The cultures were Gigaspora ACP-1 (M1), Glomus ACP-2 (M2) and Scutellospora ACP-2(M3) contained about 468, 554 and 540 spores per 100 gm culture, respectively. Interactions between strains of mycorrhizal fungi and doses of zinc resulted significant increase
