Effect of bacterial inoculation population of vegetative properties of three barley cultivars (Hordeum vulgare.L)

Abstract

The study was conducted in the winter season (2020-2021) in Al Bulatif area - Al Muthanna Governorate using a randomized complete block design with three replications in order to study effect of different population of the biological inoculum (0.5, 1, 1.5%) without applying (B1) and at a concentration of 0.5 kg.ha1 (B2) , and at a concentration of 1.0 kg H1 (B3), and at a concentration of 1.5 kg.H1 (B4), in some vegetative properties on the growth and yield of three cultivars of Hordeum vulgare L. (Al Buraq,A2 Ebaa 99, A3 Ebaa 265), and through the statistical analysis it was evaluated that the addition of different population of the bio-bacterial gave significant differences compared to the comparison treatment. Treatment (B4) The highest percentage of increase in most of the studied properties was for barley plant (plant height, leaf area, grain yield) and the average properties were (96.57 cm, 16.570 cm2, 2.95 tons ha-1 ) respectively compared to the control treatment (without applying the biofertilizer).
