Increasing salinization of fertile soil is becoming a serious agricultural problem. Arbuscular mycorrhizal (AM) fungi improve plant growth by improving nutrient mobilization under salt stress. A greenhouse experiment was undertaken to check effect of Glomus mosseae, Glomus fasciculatum on mineral uptake of Arachis hypogaea under various salinity stresses. The experiment comprised of five salinity levels (EC: 1.04 (control), 2.10, 3.78, 5.94, 8.26 dS/m) and four mycorrhizal status as non-mycorrhizal (uninoculated), G. mosseae and G. fasciculatum individually and their mixed inoculation. Under salinity stress, mycorrhiza inoculated plants showed significant increase in Cu, Zn, K/Na, Mg/Na and Ca/Na ratios but, highest accumulation (P: 53.33%, Cu: 34.36%, Zn: 21.52%, Ca/Na: 50.43%, K/Na: 42.06% and Mg/Na: 57.26%) was observed in plants inoculated with mixed mycorrhizal fungi. Hence, in amelioration of salinity stress and to prevent nutrient imbalance in A. hypogaea plant, G. mosseae and G. fasciculatum in mixed treatment can be used. |
