The suitable medium for improving the productivity and quality of oyster mushroom [electronic resource].

Includes references.

This study was conducted during the period from 2008-2009 in Mushroom Research Laboratory, Horticulture Department Faculty Of Agriculture, Zagazig University to determine the suitable media and their mixtures that enhance the yield and its components as well as fruit bodies quality of oyster mushroom. The organic substrate used for the cultivation of mushroom were rice straw, clover hay and sugarcane bagasse each was used alone or in binary mixtures; viz., 1:1, 3:1, 1:3 (w/w) as dry weight bases. The obtained results showed that, the highest values of both average cluster weight (gm) total fresh mushroom yield/bag, and biological efficiency were obtained when mushroom cultivated on rice straw alone, rice straw +clover hay (3:1, w/w) and rice straw + sugarcane bagasse (3:1, w/w).Whereas, the maximum early yield/total yield percentage was obtained when mushroom was grown on clover hay medium alone. On the contrary, cultivation of mushroom on sole clover hay medium produced the lowest number of clusters per bag followed by clover hay medium + sugarcane bagasse medium (3: 1,w/w) and rice straw + clover hay medium (1: 3,w/w). On the other hand, the obtained results indicated that the highest protein and phosphorus percentages in fruit bodies of mushroom were recorded when it was grown on clover hay medium alone, clover hay + sugarcane bagasse medium (3: 1,w/w) and rice straw + clover hay (1: 3,w/w). Cultivation oyster mushroom on sole sugarcane bagasse medium and on rice straw+ sugarcane bagasse as medium gave the lowest value of potassium percentage in fruit bodies.
