تقييم كفاءة عزلتين محليتين من بكتريا Pseudomonas putida كمخصب و مبيد حيوي

Abstract EN

This study was conducted as an attempt to produce a biopesticide- biofertilizer from two local Pseudomonas putida isolates .

P.

putida was isolated and identified from rhizosphere soil samples collected from different sites at Al-Ramadi city.

The study also included the use of bentonite and wheat bran as carriers for these isolates to produce a biopesticide-biofertilizer.

The results showed that the produced biopesticide-biofertilizer decreased wheat infection by Pythium spp when bentonite and wheat bran were used as carriers, specially when used at a rate of 50 or 100 g/ kg grains while increased seed germination , number of tillers, plant length, shoot dry weight and grain yield.

One of these two isolates was superior in its effects as biological agent when used with wheat bran as a carrier and used at a rate of 100 g/ kg of wheat graiins.
