Mushroom Yield

Supplementation of compost at casing with various ground seeds caused greater increases in mushroom yield than their respective seed oil meals when supplemented and compared at equivalent rates of nitrogen addition.Supplementation with various refined and crude seed oils increased mushroom yield, particularly in the first break or flush of mushrooms. This constitutes evidence for a relationship between lipid metabolism and the initiation of fruiting in the cultivated mushroom, Agaricus bisporus (Lange) Sing.

Mushroom Yield

The toxicity of boron (B) and copper (Cu) to cultivated mushrooms was tested in 2 experiments. The growth of mushroom mycelium (Agaricus bisporus) on potato dextrose agar in vitro was inhibited by additions of B as H3BO3 and Cu as CuSO4.5H20. Boron was more inhibitory than Cu to mycelial growth. Addition of B to compost at spawning decreased sporophore (i.e. mushroom) production and increased B concentrations in the sporophore. Boron added at 35 mg/kg of fresh compost gave a 10% yield reduction and this was associated with a sphorophore tissue B concentration of 170 mg/kg dry weight. Addition of Cu to the compost had no effect on the final yield of mushrooms but increased Cu concentrations in the sporophores. Boron added at 5, 10 and 20 mg/kg and Cu at 10 mg/kg of fresh compost stimulated sporophore growth at first flush but this was not evident in total mushroom yield from all flushes. There was a significant negative linear effect of mushroom tissue B (r2=0.98) and Cu (r2=0.54) at harvest 1 (day 1) on the change in tissue B or Cu from harvest 1 to 6 (day 17). This suggested that tissue B was buffered around 7 mg/kg and Cu around 73 mg/kg. The results indicate that the levels of B and Cu which are normally contributed to mushroom compost from poultry litter are unlikely to cause significant losses in mushroom production.

Mushroom Yield

Addition of cottonseed meal to the casing material, rather than to the compost, was examined as an alternative method of nutrient supplementation in the cultivation of the common mushroom Agaricus bisporus. Formaldehyde and calcium sulfate were used independently to prepare delayed release supplement. Casing supplementation significantly (Pv0.05) increased mushroom production (by 0.5-52% in the different trials) and required significantly less nutrient than compost supplementation. It did not result in the increased compost temperature from microbial thermogenesis that is associated with compost supplementation. A supplementation rate of 6 or 8% (on a fresh weight basis) could be recommended. Increases in mushroom yield from the use of formaldehyde and calcium sulfate were not significantly different but calcium sulfate treatment is quicker and less hazardous than formaldehyde treatment.

The aim of this study was to test a biofungicide based on Bacillus subtilis Ch-13 and its effectiveness in the control of green mould disease of cultivated mushroom in comparison with the fungicide prochloraz. Biofungicide effectiveness in disease control and impact on yield were evaluated on Agaricus bisporus after its natural infection with Trichoderma aggressivum in a commercial mushroom growing facility. An assay for testing the microbial efficacy of the biofungicide was conducted in two different procedures involving either three or two split doses. The highest statistically significant effectiveness in green mould control was shown by the fungicide prochloraz (71.43%), followed by the biofungicide applied in tree split doses (53.57%), and finally its two doses (45.46%). The biofungicide significantly improved yield in comparison with an untreated control and the fungicide prochloraz. Three split applications of B. subtilis strain Ch-13 enhanced mushroom yield to a larger extent than its two split doses, although the same final amount was used in both procedures. Biofungicide application in three split doses increased the total mass of harvested mushrooms 8.41% compared to the untreated control, and 10.53% compared to the fungicide prochloraz. These results implied that the biofungicide should be applied in three split applications: 30 ml (second day after casing) + 15 ml (two weeks after casing) + 15 ml (after first flush, 20-25 days after casing). The biofungicide B. subtilis Ch-13 should be further investigated regarding its joint usage with chemical fungicides in different application procedures, as it showed remarkable characteristics both in terms of promoting mushroom yield and inhibiting the spread of mycopathogenic T. aggressivum.

Agricultural Straws

Agricultural straws (AS) may serve as potential base-substances in the production of Agaricus bisporus. Six AS that occur across China were investigated in a two-stage composting experiment; lignocellulose components, AS morphology, and the effects of different AS on mushroom yields from 2015–2017 were examined. In addition, microbial biodiversity and their impact on substrate degradation were studied using 16S gene sequenc based on six different AS on the 3rd (I.F), 6th (I.S), and 10th (I.T) day of Phase I, and Phase II (II). Results showed that the six different AS exhibited differences in the progression of degradation under the same compost condition; the wheat straw, rice straw, and cotton straw induced a significantly higher mushroom yield than did the others (P < 0.05); Thermobispora, Thermopolyspora, and Vulgatibacter genera may play an important role in the different AS degradations. According to our experiments, we can adjust formulations and compost methods to obtain high-yield mushroom compost based on different AS in the future.
