Abstract

The purpose of this study was evaluation of the effects of Azotobacter nitrogen fixation bacteria in combination with Pseudomonas putida phosphate solubilizing bacteria on reducing the effects of irrigation water shortage on soybean cultivars under field conditions. This study was carried out as a factorial experiment in a randomized complete block design with three replications in Tarbiat Modarres University during 2015-2016. Treatments were irrigation including optimal irrigation, mild stress, moderate stress, and severe stress based on 15, 30, 45, and 60 percent of available water depletion, respectively from the establishment time to the end of the growth period and four levels of soybean inoculation with bacteria (control or without bacteria, inoculum with Azotobacter, inoculation with Pseudomonas putida, and inoculation with both bacteria). Results showed that the main effect of irrigation regime on all traits were significant except 1000 seed weight and the main effects of bio-fertilizer were significant except for 1000 seed weight, seed nitrogen, and oil on all traits. From the test results, one can conclude that Azotobacter alone increased 17. 9% seed yield, Pseudomonas putida alone increased the yield of 32. 4%, and the combined application of both bacteria increased the grain yield by 39. 8%. In general, considering the non-insignificant effect of bio-fertilizer interaction on levels of water stress, it was concluded that the application of bio-fertilizer under favorable irrigation conditions and under drought conditions is effective in improving yield and yield components, protein, and oil yield of soybeans.
