background and objectives: soybean is one of the plants that need large amounts of nitrogen for grain yield production. todays bio-fertilizers are considered as a best replacement for chemical nitrogen to increase soil fertility and sustained agricultural production. meanwhile, the use of soybean symbiotic bacteria and nitroxin, which contain the most effective nitrogen-fixing bacteria of the g...

introduction considering the nutrient loss, environmental pollution and increase in production costs on account of chemical fertilizer application, supplying mineral nutrients based on organic sources and mycorrhizal inoculation can improve organic matter content in soil (khandan & astaraei, 2005; halajnia et al., 2007), promote sustainable production of oil crops (mostafavian et al., 2008; kaw...
