The possibility of using hazelnut husk (HH) as a new basal ingredient for substrate preparation in Lentinula edodes cultivation was investigated. Some chemical properties of the substrates prepared by HH alone and its mixtures with wheat straw (WS), beech wood-chip (BWC) and wheat bran (WB) in different ratios were compared, and their effects on spawn run time, days to first harvest (earliness), yield and biological efficiency (BE) were determined. The N content of the substrate prepared from HH alone was very high (0.82%), and thus the C:N ratio of substrates decreased with an increase in the rate of HH in the mixtures. Yield and BE in the HH alone substrate was considerably low compared with the controls (80BWC:10WS:10M and 60BWC:20WS:20WB), and decreased with an increase in the rate of HH in the mixtures. However, when the HH content in the mixtures was kept below 50%, the yield was relatively high (50HH:50WS and 50HH:50BWC). Even when the HH content increased to 75% in the mixture, the comparable yield and BE to the controls could be obtained by adding 10% of WB as nutrients (75HH:15WS:10WB and 75HH:15BWC:10WB). The results revealed that HH could be used as a new basal ingredient for substrate preparation in L. edodes cultivation.
