Effect of subtract amount and self-position on yield oyster Mushroom (P. Sajor Caju)

Abstract

Experiments were conducted at Department of Plant Pathology, T.D.P.G. College, Jaunpur Uttar Pradesh, in the two consecutive year 2010-2011 and 2011-12.Edible mushroom Pleurotus sajor caju (Fr.)’ to evaluate the varying amount of substrate for the production of P. sajor caju. The experiments were laid out in completely Randomized design. In order to study the effect of different quantity of wheat straw on the yield of P. sajor caju, an experiment was conducted with six replications and five treatments viz. 0.75 kg, 1.00 kg, 1.25 kg, 1.50 kg, and 2.0 kg dry wheat straw as substrate. The substrate preparation was done by using technique described earlier in cultivation techniques. Out of these different quantities of substrate used, the 2.0 kg dry substrate gave the maximum yield. This was followed by the yield obtained from 1.50kg, 1.0 kg and 0.750 kg dry substrate. The result also revealed that the biological efficiency of 1.25 kg and 1.0 kg substrate were found superior during 2011 and 2012 respectively in comparison to other treatments. It may be attributed due to increase in growing surface area.
