INFLUENCE OF VERMICOMPOST ON THE PARAMETERS OF PRODUCTION OF EDIBLE MUSHROOMS: CASE OF PLEUROTUS OSTREATUS (KUMMER, 1871)

Abstract

One of the major problems to the promotion of mushroom culture is the weak productivity of 
the substrata. The present work, had for objective to formulate a substratum susceptible to 
increase the profitability of culture of Pleurotusostreatus, to identify the best composition of 
the organic substrata to use in vermicomposting for an improvement of the production of 
Pleurotusostreatus. Two substrata have been formulated. The substrata have been divided in 3 
shares each and submitted to 3 treatments of (15 ± 3, 30 ± 3 and 45 ± 3) days by 
vermicomposting in the goal to determine the best level of mineralization for mushroom 
culture. These treatments are compared to the control substratum constituted of sawdust of 
wood (94 %), rice bran (5 %), CaCO3 (1 %) composting during 45 ± 3 days. The comparative 
survey of the biologic and economic outputs of the substrata showed that the vermicomposts 
got better results in relation to the control substratum. It is some in the same way for the 
results of the biologic efficiency as well as the middle number of runts.
