Evaluation of certain local bacterial strains as diazotrophs for wheat plants [electronic resource]. تقييم سلالات بكتيرية معينة كمثبتات نيتروجين جوى لنباتات القمح. P.263-278. Includes reference Nine identified bacterial strains were selected out of 48 isolates collected from various areas in the upper Western region of the Nile Delta in Egypt. Such 9 strains proved to be the most biofertilizing bacterial agents among all via laboratory examinations. A greenhouse pot experiment was carried out in order to ascertain the capability of those strains as effective diazotrophs for wheat plants. Influence of soil moisture content and salinity was included. Nitrogen contents in plant shoots and in rhizosphere soil, as well as dehdrogenase activity, had been determined at two growth periods, i.e. 60 and 120 days of planting. The results revealed that the strain "D 2" ( Azotobacter chroococcum DSM 2286), "D9"( Enterobacter kobei CIP), "M3"( Bacillus megaterium EIF18), "N4" (Clostridium sp.), and "W2" (Klebsiella sp.), were, descendingly the most efficient strains, under all experimental variables.
