Effect of Sterilization of Substrate by Hot Water Treatment on Prevalence of Contaminants and Yield Attributes of Oyster Mushroom (Pleurotusostreatus)
Journal Title: Scholars Journal of Agriculture and Veterinary Sciences - Year 2017, Vol 4, Issue 11
Abstract
Abstract:An experiment was conducted to evaluate the influence of hot water treatment of rice straw on yield, yield attributesand contamination of oyster mushroom (Pleurotusostreatus), rice straw subjected to hot-water treatment at 600C, 800C and 1000C temperature. Each temperature was maintained for 1hr, 2 hour and 3hour, which were compared with untreated (without hot water treatment). There were significant effects of substrate pretreatment methods on contamination, yield attributes and biological efficiency. Different dominant contaminants were found such as, Trichoderma harzianum, Coprinus spp.,Apergillusniger and penicillium sp. were obtained during the incubation and cultivation period of the spawn. The contamination of rice straw was higher at non-treated spawn packets and from 600C treated packets. Better performance, such as BE was 57.44%, the economic yield (280g), the highest average diameter of pileus (5.0 cm) and the highest average length of stipe (3.70 cm) were obtained from the treatment of 800C for 3 hours. Keywords:Oyster mushroom, Trichoderma harzianum, Coprinus spp.,Apergillusniger , penicilliumsp
