Effect of pseuodomonas flourescence and trichoderma harizianum on the efficiency of rhizobium in chickpea

الملخص EN

The present study included isolating and diagnostic eight of Rhizobial isolates from chickpea and fababean root nodules taken from different Iraqi region, and two nonlocal Rhizobial strains of chickpea plants obtained from ICARDA.

Two separated experiments on chickpea planted in pots were done inside the green house.

From the first experiment we notes significant increased in all qualities of chickpea plants treated with all Rhizobial isolates compared with the control.

Rd6 isolate was the best one among these Rhizobial isolates.

In the second experiment Chickpea seed treated with Rhizobial isolates and one or both of the bio pesticides T.

harzianum, P.

fluoresces.

The bio pesticide added also in another way by treated the soil of pots with it.

The result shown that Rq8 isolates recorded best results, chickpea plants treated with this isolate have shown best results, the interaction treatment was the best treatment among all the other treatment and seed treatment with bio pesticide better than soil treatment.

No nodulation in the plants roots were observed in the greenhouse experiment in the most treatments except when the strain CP-93 was used.

Field experiment was done in Alqoosh town using the best three isolates that were the best in the first experiment to test the effects of the environment conditions on the isolates efficiency the isolates were (Cp-93, Rd6, Rm1).

Results was (52, 44 and 36) nodule / plant in (1.664, 1.408 and 1.152) gm / plant while the un inoculated plants (control) recorded 21 nodule / plant in 0.609 gm / plant.
