| Popis: | The present investigation was conducted to study the effect of various growth regulators and micronutrients on growth and yield of Pleurotus sajor-caju. Results of the research explicitly indicated that the growth regulators and micronutrients experimented at different concentrations, targeting at stimulating growth and sporophore yield of Pleurotus sajor-caju, displayed significantly diverse response to in vitro colony diameter of the fungus, days required for spawn run, pinhead formation, first harvest of sporophores, yield of sporophores and biological efficiency. However, among the growth regulators used, gibberellic acid (GA) @ 20 and 15 ppm significantly improved the colony diameter (90 and 89.98 mm) in in vitro study; reduced the period required for spawn running (13 and 13.5 days), pinhead formation (16 and 16.5), and first harvest (18.5 and 19); augmented the total sporophore yield (858.25 and 855 g/kg dry substrate) and biological efficiency (85.83 and 85.5%). Mixture of micronutrients was ineffective in augmenting the foregoing traits. From the present investigation it is concluded that, spraying of gibberellic acid at 20 and 15 ppm concentrations on cultivation substrate, at the time of spawning, is highly beneficial for obtaining maximum yield of Pleurotus sajor-caju. |
