Studies on effect of different organic additives wet weight basis cereal flour on fungal disease incidence and yield of oyster mushroom

Abstract

Mushroom has got important place in religious books. They are the fungi, which lack chlorophyll and therefore, they cannot use solar energy to manufacture their own food (Photosynthesis) as green plants. The experiments for the present investigation were conducted the Culture of Pleurotus Florida were purified and maintained by single hyphal tip method. For this purpose, the cultures were grown in sterilized Petri plate on Potato Dextrose Agar Medium (PDA) for 8-10 days. The result indicated that maximum yield (790g/kg of dry substrate with 79% B.E.) was observed in wheat straw + rice flour which was statistically higher then all other treatments. It was followed by wheat straw + maize flour (783.33gm/kg of dry substrate with 78.30% B.E.). The minimum yield was observed in control i.e. only wheat straw (456.67gm/kg of dry substrate with 45.66% B.E.) flowered by wheat straw + wheat flour (590.00gm/kg of dry substrate with 59.00% B.E.), which are significantly higher than control (wheat straw alone) control significantly lower than all other treatments. The highest number of fruiting bodies (139.67) was observed from wheat straw + maize flour which was statistically higher than all other treatments. The minimum number of fruiting body (90.00) was observed from wheat straw + wheat flour which was statistically at per with wheat straw + sorghum flour, wheat straw + oat flour and wheat straw + Rice flour and wheat straw + bajra flour. The maximum days for spawn run (19.67) were observed in control. The minimum days of first harvesting (25.67) was observed at wheat straw + maize flour which was statistically lower then all other flours. Disease incidence the maximum percentage (17.29%) observed at wheat straw + oat flour followed by (16.46%) wheat straw + wheat flour minimum incidence observed (10.95) wheat straw + maize flour.
