Abstract
Barley is the forth important cereal crop in the world, and salinity is one of the most limiting factor for crop productivity. This research aimed to study the impact of Bacillus megaterium inoculation to three varieties of barley under 5 different salinity level (0, 50, 100, 150 & 200 mM).
This study revealed that B. megaterium have positive impact on agronomic traits of barley such as on leaf length, width and number, root weight, shoot weight and plant height and chlorophyll B. megaterium inoculation show increasing in the level of awn roughness slightly.
At moderate salinity level the response of plants to bacterial inoculation was positive on K+, Ca+, N+ and P accumulation this indicate that B. megaterium increase uptake of nutrient under saline condition to certain degree.
The study indicates that B. megaterium improve the growth of Nabawi and Icarda5 barley’s varieties under saline condition and reduce the accumulation of Sodium and Chlorides compared to non-inoculated plants.
