The Effect of a Local Bacterial Isolates of Pseudomonas spp in Growth and Elements Nutrition Uptake of (Vinga sinesis) & (Rhaphanus stativus)

Abstract

  An experiment was conducted  to study the effect of four isolates of Pseudomonas   spp. on the growth of two plants  Radish & Cowpea  and on the concentrations of macro elements & microelements  . This experiment included two parts , the 1st. part included isolation and characterization of 4  isolates of Pseudomonas bacteria from local  Iraqi soils  Baghdad  . The 2nd part included planting two plants  Radish & Cowpea  in plastic pots size 5Kg -soil in the green house Biology Dept. College of Science , after planting  we added the isolates to the pots , and after 50 days, the growth parameters  length , fresh and dry  weight , percentage  of germination  were recorded  , and the concentrations of macro elements  Mg ,P ,K ,Fe, and Ca ,and microelements Zn ,Cl ,Mo ,Cu ,and  Ba. The results showed that the bacterial isolates were effective in promoting the growth of two plants comparing with control plants , the concentrations of maco & microelements were increased in both plants after adding the bacteria to the plants. Results were analyzed statistically using the least significant difference  and at the level of probability of 0.05.
