Abstract: An attempt was made to screen forty native AM fungal isolates from the soybean rhizosphere of Belagavi and Dharwad districts based on their peroxidise activity and total dry matter accumulation in soybean under the restricted water regime of -500 kPa. Top three fungal isolates viz., UASDAMFS15, UASDAMFS25 and UASDAMFS36 tentatively identified as G. maculosum, G. manihotis and G. globiferum respectively. For pot culture studies three irrigation regimes were maintained viz., -33 kPa -500 kPa and -1000 kPa. An experiment was laid out in completely randomized design with factorial concept. There were twenty one treatments and four replications. In general, AMF inoculations reduced the moisture stress in plants significantly. Among them, UASDAMF consortium and UASDAMF soybean consortium significantly increased the stomatal conductance, photosynthetic activity, transpiration rate, ACC deaminase activity and leghaemoglobin content in the plants. Further, UASDAMF consortium and UASDAMF soybean consortium greatly reduced the leaf temperature, proline, glycine betaine content, peroxidase and PALase activity in the plants compared to single inoculants and UIC. Thus, our preliminary findings are indicative of the effectiveness of AMF in protecting plants from water stress and hence can be a promising strategy to develop a biological tool for mitigation of moisture stress.
