Abstract:
In the present investigation attempts were made to study the effect of various growth regulators to find out most effective dose of the growth regulator for increasing the yield, mycelial growth and biomass production of oyster mushroom (Pleurotus sajor-caju). The investigation was undertaken during July- October, 2019 at the Plant Pathology Section of College of Agriculture, Kolhapur. Results of the investigation overtly indicated that the growth regulators tried at different concentrations in the present investigation, aiming at promoting yield of oyster mushroom (Pleurotus sajor-caju), exhibited significantly varied response to yield of mushroom and biological efficiency. However, amongst the various growth regulators used in the present investigation, spraying of gibberellic acid (GA) 10 ppm significantly demonstrated its efficacy over other treatments increasing total yield of mushrooms (856.81 g) and biological efficiency (85.68%).
