Abstract:

 A field experiment was carried out in the fields of the College of Medicinal and Industrial Plants, University of Kirkuk, to study the effect of biological inoculation in increasing available phosphorus in the soil and some growth characteristics of the barbin plant, and the interaction between them. A randomized block design with three replicates of the first factor, calcareous and gypsum soil, and the second factor, two types of bacteria and P fluorescence B megatrium., the results showed that the treatments inoculated with bacteria increased the amount of phosphorus available in the soil, plants, and all the studied plant characteristics compared to the non-inoculation treatment. The best treatment was the inoculation treatment with B megatrium bacteria in the calcareous soil the amount of available phosphorus in the soil reached 10.1 mg p kg-1, and the amount of phosphorus in the shoot system was 0.22. %, and the amount of phosphorus in the root system was 0.12%. The plant height reached 26.1 cm, the root length reached 11 cm, the dry plant weight was 5.1 gm. plant-1, the weight of the root system was 1.5 gm. plant-1, and the vegetative fresh weight was 162.8 gm. plant-1 the root fresh weight was 29.8 gm. plant-1 compared to the non-inoculation treatment, as the amount of available phosphorus in the calcareous soil was 6.5 mg p kg-1, the amount of phosphorus in the shoot system was 0.15%. the interaction treatments significantly affected most growth characteristics..
