Abstract
In order to investigate the effect of plant growth promoting rhizobacteria on grain yield and gas exchange of new dryland wheat cultivars, a factorial field experiment was counducted in a randomized complete block design with three replications on the farms of Sarablah Agricultural Research Center in the cropping seson during 2019-2020. Experimental treatments include different wheat cultivars (Sardari, Karim, Koohdasht and Rijo) and treatment of different fertilizer sources including: control (without fertilizer source), 50% N fertilizer, Azospirillum + 50% N fertilizer, Azetobacter + 50% N fertilizer, Azospirillum + Azetobacter + 50% N fertilizer and 100% N fertilizer. The results of this study showed that the interaction of cultivar×different fertilizer sources was significant on grain yield, yield components as well as gas exchanges of dryland wheat. the highest grains.spike-1 (80%), 1000-grain weight (33.3%), grain yield (86.3%), biological yield (79.9%), photosynthesis rate (81.8%), transpiration rate (74.8%), mesophilic conductance (85%), photosynthetic water use efficiency (42.3%) was obtained from the interaction of Rijo× Azospirillum+Azetobacter +50% N fertilizer and the lowest value of these traits was related to the interaction between Sardari cultivar control treatment (without fertilizer source).
