Effect of Inoculation with Psudomones fluorscens bacteria and Different Levels of Phosphate rock on the Growth and Yield of the Plant Vigna radiata.L

Abstract

The pots experiment has been conducted to investigate the effect of inoculation of Psudomones fluorscens bacteria with two levels of Phosphate rock (60 and 120 Kg. ha-1) on growth and yield of livestock plant Vigna radiate. L. Two strains of Psudomones fluorscens that dissolves phosphor have been isolated from the rhizosphere area of okra and corn crops which are symbolized as P1 and P2. xpectivly results revealed surpass bacteria strains over the example strain in most characteristics and P1 has surpassed P2 in the studied chriteria as the rate of nodes (4.67 node plant-1) and the dry weight of the nodes has come to 12.63 mg plant-1. The strain P1 has surpassed in the number of pods and the number of seeds in a pod and the rates of (11.33 node plant-1) and (6.78 seed pod-1) have been recorded. The results have showed the surpassing of the level (120 Kg ha-1) over the level( 60 Kg ha-1) in most studied chriteria as the dry weight of the greenery total recorded by the level (120 Kg ha-1) has been (3.56 gr plant-1) and the rate of the absorbed Nitrogen amounts to 7.41 mg gr.-1 while the rate of the absorbed phosphor is( 1.01 mg gr.-1). The of pods that the level (120 Kg ha-1) has recorded is( 11.0 pod plant-1) . The interaction treatment between the bacteria Psudomones fluorscens and phosphate rock has surpassed in all studied characteristics. The interaction treatment between the strain P1 and the level (120 Kg. ha-1) has recorded the highest rates and in most characteristics as it has recorded the highest rates in the number of root nodes and its dry weight which amount to (10 node plant-1) and( 26.89 mg plant-1). It has also recorded the highest rates in the number of pods and the plant yield of seeds which amount to(13.0 pod plant-1) and (2.1 gr plant-1) respectively.
