In: Fayoum Journal of Agricultural Research and Development 2016.v.30(2)Summary: Complete identification was made for three strains of the facultative putative N2-fixing bacteria using the 16s DNA sequencing studies and by detailed conventional API kit and other possible genetic detennination. The efficacy of Bacillus subtilis subsp. spizizenii strain NRRL B-23049T (S4), Naxobaeter varians strain CCUG 35299 (S5) • and Bacillus megatherium strain IAM 13418. (S6), their potency against two pathogenic fungi causing damping-off and their effect on N-content of tomato plant. Inoculated tomato plants with any of the three bacterial it strains, each alone or together, in presence of 1/3 N-recommended dose, significantly increased N-content and yield production. The fungi infested plants (Py. altimum and R. solani) showed pronounced decreases in yield and N-content.
