| Abstract |
Medium heat treatment cost represents high proportion of total cultivation cost and consumes much time and effort. It is very important to study how we can make the mushroom cultivation much profitable. Pleurotus ostreatus, Flammulina velutipes and Hericium erinaceus were grown on unpasteurized, pasteurized (mild heat treatment) and sterilized rice straw medium under local climatic conditions. Incubation period (days), yield (g/kg wet medium), biological efficiency (BE%)and infection rate were studied. H. erinaceus mycelium could not grow on unpasteurized medium in all growing attempts. The incubation period of the tested mushrooms ranged from 17 to 35 days. P. ostreatus yielded 275- 330 g/kg wet unpasteurized medium. The yield of P. ostreatus grown on pasteurized medium was 370- 430 g/kg wet medium.On the other hand, using the autoclaved medium increased the yield by about 5-11.8 % compared to those gained from pasteurized ones. F. velutipes grown on unpasteurized medium yielded relatively low yield being 157- 168 g/kg wet medium in the first season. The pasteurized medium increased yield to reach 210- 320 g/ kg wet medium. The yield of F. velutipes in both cases (pasteurized and unpasteurized) were taken in only two fiushes which first flush represent about 80% of the total yield. The yield of F. velutipes grown on autoclaved medium ranging from 340-370 g/kg wet medium. H. erinaceus grown om pasteurized medium yielded so low yield being 75-120 g/kg wet medium (21-29%BE). By using sterilized medium the yield increased to reach 160-230 g/kg wet medium with BE 42-61% . Under the conditions of this investigation, it could be concluded that, satisfied yield of P. ostreatus could be obtained from unpasteurized medium. Also good yield of F. velutips could be obtained by growing on pasteurized medium. Meanwhile, H. erinaceus only gave good yield by using sterilized medium. For alltested mushrooms most yields were obtained from first and second flushes. Alternative media preparation methods could mean saving time, effort and money to make mushroom cultivation much profitable especially for farmers and small growers to get sustainable development in our rural communities.
