Abstract
This study determined the influence of different grain spawn materials namely: sorghum, sweet sorghum, cracked corn, feed concentrate and unmilled rice on mycelial growth and fruiting body performance of P. florida on a rice straw based substrate.
Among the different grain spawn materials evaluated, sorghum registered faster mycelial growth with the mean 13.63 mm per day respectively and unmilled rice exhibited lowest mean of 13.19 mm per day. In terms of fruiting body performance, cracked corn and feed concentrate recorded the shortest incubation period with a mean of 23.67 days. On the other hand, the sorghum and feed concentrate exhibited the highest yield and biological efficiency with a mean of 190.22 and 183.89 grams of total yield and biological efficiency with a mean of 27.17% and 26.27% respectively after the three flushes.
Overall, based on the result gathered, the most suitable cellulosic grain spawn materials for P. florida is sorghum with a faster rate of mycelial growth per day, with higher yield and biological efficiency.
