Abstract:
Among the factors attributed to the productivity of mushrooms, type of substrate and supplements used for its cultivation is substantially important. The present study highlights the effects of different supplements viz. rice bran (10%), bengal gram powder (10%), poultry manure (10%), spent mushroom compost (10%), urea (2%) and ammonium sulphate (2%) and different growth regulators viz. Indole acetic acid (IAA), indole-3-butyric acid (IBA), gibberellic acid (GA), naphthalene acetic acid (NAA) and kinetin (10 ppm each), on the growth and yield parameters of Jew’s ear mushroom (Auricularia auricula-judae). Experiment was done by polybag method of cultivation during the monsoon seasons of 2021-22. The results from this study revealed that rice bran was the best supplement (total yield, 308.42 ± 16.36 g/kg) and GA was the best growth regulator (total fresh yield, 413.37±28.08 g/kg) for the growth and yield enhancement of Jew’s ear mushroom. Among the supplements used, spent mushroom compost was found to be the poor yielder with biological efficiency of 16.59% and in case of growth regulators, kinetin was found to show minimum yield (BE-28.22%). Faster spawn run was observed in beds supplemented with urea whereas among growth regulators, GA showed faster spawn run compared to control.
