Abstract

Among the various mushrooms widely found in India, Pleurotus florida is gaining its popularity due to its vigorous growing and aggressive nature. This creamy white colored mushroom is popularly known as ‘White oyster mushroom’. The addition of the supplements with basal substrate has been a common practice for optimization of the C:N ratio, enhance the yield, nutritional and medicinal values. The present investigation was carried out to find the best supplement combination for the cultivation of Pleurotus florida. Two supplements namely rice bran and soybean flour in different composition were mixed with the wheat straw to enhance the mushroom yield. Spawning was done @ 3% wet weight of wheat straw. The results of the present investigation revealed that supplemental combination (20% rice bran + 5% soybean flour) used in T4 recorded significantly less time for spawn run (10.66 days), pinhead initiation (12.66 days), formation of the mature fruiting body (14.83 days).

Conclusion

As per the results obtained from this study, the combination of the supplements with wheat straw in T4 (20% rice bran + 5% soybean flour) took significantly less time for complete spawn run, early primordial initiation and early maturity of the fruiting body. The significantly highest average width of pileus (cm) and stipe length (cm) were also recorded in T4 (20% rice bran + 5% soybean flour). The significantly maximum number of fruiting bodies was also obtained in this treatment combination (20% rice bran + 5% soybean flour). Among the treatment combinations, T4 (20% rice bran + 5% soybean flour) recorded significantly higher yield in all three flushes and biological efficiency. Therefore, it is concluded that substrate mixture in T4 (20% rice bran + 5% soybean flour) is the most suitable combination in terms of increasing growth and yield of white oyster mushroom as compared with control (without supplements). The results of the present study are of one cropping season (January 2021
