Effects of casing soil enrichment with soybean flour (SF) and iron (Fe) were explored on yield and quality of edible mushrooms inoculated with plant growth-promoting bacteria in a factorial experiment with four replications. Fe from Fe chelate source was applied at two levels of 0 (Fe0) and 500 mg L-1 (Fe500), SF at three levels of 0% (SF0), 1.5% (SF1.5), and 3% (SF3) of compost dry weight, and bacteria inoculation at two levels (non-inoculation and inoculation of mycelia with P. putida). The maximum fresh yield (20.3 kg m-2), mushroom number (1041), biological efficiency (95.0%), vitamin C (3.74 mg 100 g-1 FW), and yield of protein (6.48 kg m-2) were obtained from SF1.5 + P. putida. But, the maximum tryptophan (1.37 mg g-1 DW), methionine (2.29 mg g-1 DW), and antioxidant capacity (4.25 mg mL-1) were related to SF3 inoculated with P. putida. Furthermore, the maximum carbohydrate (5.64%) was related to Fe500 + SF3. Based on the results, casing soil enrichment with Fe did not have a significant influence on quantitative and qualitative traits of mushrooms, but SF application at the rate of 1.5%, especially when accompanied by P. putida, played a more essential role. Thus, it is recommended to use 1.5% SF along with P. putida to enhance the yield and qualitative traits of edible mushrooms.
