Responses of Seed Yield, Yield Components and Some Morpho-physiological Traits of Wheat Cultivars (Triticum aestivum) to the Application Methods of Fulzyme Biofertilizer

To study the effect of application methods of Fulzym biofertilizer (containing Bacillus subtilis) on yield¡ yield components and some morpho-physiological characteristics of four cultivars wheat¡ an experiment was conducted in field of Astan Quds Razavi in 2010- 2011. The experiment performed was in split plot based on randomized complete block design with three replications. Four wheat cultivars (Falat¡ Pishtaz¡ Bahar and Toos) were assigned to main plots and four biofertilizer application methods (as seed inoculation¡ using in irrigation water¡ seed inoculation and irrigation and control) to sub plots. Results indicated that Falat had the lowest plant height (61.5 cm) than other varieties. Plant height of Toos and Pishtaz were about 14.5 percent higher than Falat. Application methods of Fulzym increased chlorophyll content and plant height. Highest chlorophyll contents were obtained when seeds inoculated by Fulzyme and used through irrigation. At the end of growing season¡ it was found that chlorophyll content of Falat and Toos flag leaves were higher than Pishtaz and Bahar. It was also revealed that Bahar when Fulzyme was used showed a better response to treatments than other varieties as for as biological and seed yields were concerned. Highest seed yield produced by irrigation and combination of seed inoculation and irrigation (9063 and 8609 kg.ha-1) and lowest seed yield (5858 kg.ha-1) to Falat in the control treatment.
