Abstract:
The experiment was carried out in mushroom research shade house of
Olericulture Division, BARI, Gazipur, during the period from July, 2015 to
December, 2015 to evaluate the effect of pH levels of substrates and frequency
of watering on the growth and yield of oyster mushroom. Spawn of Pleurotus

experiment was laid out in two factors Completely Randomized Design with
three replications. Results revealed that most of the parameters showed the
significant response due to different pH levels of substrate and watering
frequency. For pH level of substrate, the treatment P

exhibited the better
performance in respect of yield and yield contributing characters of mushroom.
In case of watering frequency, the treatment W
showed higher yield and
positive effect on growth parameters as well as on yield parameters. The

highest yield was obtained from the combined treatment of P

combination may be used for higher yield of mushroom
