dc.description.abstractMaximum colonization and the spore population of Glomus spp. was observed in the Faridkot district, while minimum in the Bathinda district. Out of the three Arbuscular mycorrhizal fungi (AMF), Glomus bagyarajii showed maximum colonization along with spore population and thus was selected for further experimental purpose. There was low mycorrhizal colonization in the root samples collected from 30 days old chickpea crop as compared to 60, 90 and 120-days crop. 80 mg ‗P‘/kg soil level didn‘t restrict the AMF colonization. G. bagyarajii inoculation significantly increased root and shoot length along with number of leaves, branches and pods in all four observations. The effect of dry root rot causing pathogen i.e., Macrophomina phaseolina on mycorrhizal colonization was observed in the presence of G. bagyarajii. The colonization of Glomus bagyarajii was found to be reduced in the presence of the M. phaseolina. The ‗P‘ level also affected significantly the AMF colonization along with abundancy of mycelium, arbuscules, vesicles and spore population in presence of pathogen. The overall effect of G. bagyarajii on dry root rot of chickpea was observed during the crop season at three levels of ‗P‘ viz., 0, 40 and 80 mg ‗P‘/kg soil at Ludhiana and Hoshiarpur. The significantly higher i.e., 100.0 and 0.0; 93.3 and 6.6; and 100.0 and 0.0; 90.0 and 10.0 per cent plants were found healthy and yellowed after 30 days of sowing at Ludhiana and Hoshiarpur districts respectively, at 40 mg ‗P‘/kg soil in the presence of both AM fungi and dry root rot pathogen. The 100 per cent infected plants in only pathogen and 100 per cent healthy one in only AMF treatment were recorded at all ‗P‘ levels. Same trend was recorded in other observations at both districts. The development of dry root rot in chickpea was reduced significantly in the presence of AMF and pathogen. The infected plants showing yellowness survived during complete crop season in the presence of G. bagyarajii. The plant growth parameters were observed significantly higher at 40 mg ‗P‘/kg soil in all the four observations at both districts. Based on the findings, it was suggested that the AM fungus namely Glomus bagyarajii managed the dry root rot of chickpea effectively and enhanced crop yield.en_US
