Abstract
In order to investigate the effect of deficit irrigation and bio-fertilizer on yield and its components of maize, an experiment was conducted as split plot in randomized complete bock design with three replications in Agricultural Research Center, Ilam, Iran in 2010-2011 growing season. Three levels of deficit irrigation (80, 100 and 120 evaporation (mm) from pan (Class A)) were assigned as main plots and bio-fertilizer (non-inoculation, inoculation with Azotobacter Chroococcum, Azospirillum brasilense and double-inoculation of Azotobacter and Azospirillum) were randomized in subplots. The effect of levels of deficit irrigation on plant height, number of rows per ear, number of grain per row, 1000grain weight, grain yield, biological yield and protein content was significant. 80 mm had the highest plant height, number of grains per row, grain yield and biological yield compared with other treatments. The effect of bio-fertilizer on plant height, number of grain per row, 1000-grain weight, grain yield, biological yield and protein content was significant was significant. Dual inoculation with Azotobacter and Azospirillum had the highest plant height, number of rows per ear, number of grains per row, 1000-grain weight, grain yield, biological yield and protein content compare with other treatments. The interaction effect of deficit irrigation× bio-fertilizer on grain yield, biological yield and protein content was significant. The highest and lowest grain yield obtained from 80 mm and Dual inoculation with Azotobacter and Azospirillum and 120 mm and non inoculation treatment, respectively. It is concluded that bio-fertilizer can positively have effect on the increase of plant in maize plant, leading to plant tolerance improving under drought stress conditions.
