Utilization and Economic Analysis of Fermented Corn Silage By Using Biogas Organic Waste In Cultivation of Pleurotus spp.
Project no. 1284 · Status: Kapanmış · 2016
Summary
In recent years, energy production with renewable energy resources are getting popular in Turkey. Biogas, which can be obtained by the processing of organic wastes, is a clean, environmentally friendly and efficient energy resource. The wastes of biogas production can also be used as fertilizer in agriculture. In this research, utilization and effects of fermented corn silage (FCS), which is one of the organic wastes of biogas production, as compost and on yield and some quality parameters of mushroom (Pleurotus ostreatus) production were investigated. Research was carried out at two production seasons. In both production season WS80+WB20 mixture was chosen as control treatment (C). In the first season, four compost treatments prepared as dry weight percentage, namely (FCS25+C75, FCS50+C50, FCS75+C25 and FCS100), was tested. When compared to control treatment, FCS50+C50 and FCS25+C75 were provided 4-2 days and 3 days earliness in terms of pinhead emergence and harvest, respectively. Moreover, yield and BE were 20% and 28% higher in FCS25+C75 than control treatment. In the second season, 5 compost treatments (FCS10+C90, FCS20+C80, FCS30+C70, FCS40+C60 and FCS50+C50) were tested. The highest yield was obtained from FCS20+C80 (241.19 g/kg). Yield of FCS30+C70 was higher than control treatment. When compared to control treatment, 2-3 days earliness and increase in BE was observed in all treatments. Differences in cap diameter, N and protein ratio was statistically significant in first season. Differences in average mushroom weight, stipe diameter and stipe lenght were insignificant in both seasons. The usage of wheat straw, wheta bran and fermented corn silage mixture as compost in Pleurotus ostreatus production can support the utilization of valuable organic wastes of biogas production in agriculture together with yield increase and earliness.
