Abstract

The present study deals with the isolation and characterization of Azotobacter vinelandii and A pots experiment was conducted at the canopy wood of Agriculture-University of Al-Muthanna (station 2) during winter season of 2016–2017 to study the effect of inoculant bacterial and irrigation water quality and their interactions on yield and growth of wheat. Treatments included four levels of inoculant bacterial (without inoculation A0 and inoculation with three locally Azotobacter vinelandii coded A1, A2A3 and three water qualities river water (0.752 ds.m−1 W0), mixed water (3.6 ds.m−1 W1) and drainage water (6.5 ds.m−1 W2). The results showed, generally bacterial inoculant treatments was superior to the un-inoculant treatment A0 in most character studied and A2 treatment achieved best result compared with other isolation locally, in height plant, dry weight plant, weight of 1000 seeds, yield and nitrogen uptake) was recorded (99.10 cm, 15.50 g plant−1, 29.29 g, 32.95 g plant−1, 73.56 mg plant−1) sequentially. Generally increasing salinity in irrigation water significantly decreased growth characters, yield, and yield components of plant. Interaction between biofertilizer treatments and salinity had a significant effect on plant growth and yield and yield components of plant and the best result were had been gave by A2W0 in all traits studied (height plant, dry weight plant, weight of 1000 seeds, yield and nitrogen uptake) which was recorded (106.88cm, 17.97g plant−1, 30.34g, 39.34g plant−1, 97.43mg plant−1) respectively.
