Effect of prevailing environment condition on growth and yield of Hypsizygus ulmarius

Abstract

Blue oyster mushroom is a novel species with very large fruit body, blue colored pinheads becoming light white on maturity, high yielder, palatable with meaty flavor and attractive keeping quality. This new mushroom variety has attractive shape and fleshy with excellent taste. The present investigation was under taken to find out the prevailing environmental conditions for growth and yield of H. ulmarius. The experiment was conducted in October 2016 to April 2017 on wheat and paddy straw substrate separately and standard for cultivation procedure was adopted. Maximum yield was observed during the month of December. when the minimum, average and maximum temperatures (20.56 oC, 20.08 oC, and 20.76 oC respectively) 83.16%(morning) to 85.90% (evening) relative humidity prevailed in the cropping room with biological efficiency 112.00% on wheat straw and 101.87% on paddy straw.
