Evaluation of the Efficacy of the Inoculum Prepared from the Two Local Isolates enterobacter colacae and enterobacter ludwigii on Soybean (glycine max l.) Growth and Yield in Gypsiferous Soil under Different Molybdenum Levels

Abstract With the aim of reducing chemical fertilizers and relying on environmentally friendly natural biofertilizers that promote plant growth increase yield, especially in gypsiferous soils spread arid semi-arid regions, which suffer from physical, chemical, fertility, biological problems, turn affect density microorganisms, This experiment was conducted to study efficiency inoculum prepared bacteria E. cloacae ludwigii isolated molecularly characterized improving yield soybeans under different levels molybdenum soil, possibly due its absence, particularly responsible for nitrogen fixation. The results showed two treatments inoculated with ludiwgii were significantly superior uninoculated treatment all studied traits percentage protein seeds, traits, as well fertilized at level 2 kg Mo ha -1 non-fertilized interaction between inoculation fertilization + comparison gave values 278 pod , 127.66 g 6.23 tons 6.27%, 39.13%. 0.36%, 0.071% number pods, weight grain concentrations nitrogen, protein, concentration remaining soil after harvest, respectively, compared 150.67 68.33 3.43 5.42%, 33.83%, 0.33%, 0.068 aforementioned characteristics, respectively.
