Characterization and optimization of indoor environmental quality on grey oyster (Pleurotus pulmonarius) mushroom cultivation

In view of increasing demand, mushroom cultivators are facing more challenges and difficulties to grow mushroom due to inconsistent environmental conditions. Controlling and monitoring of environmental quality in mushroom cultivation is an important factor for high mushroom production. Therefore, t...

Prof. Dr. In view of increasing demand, mushroom cultivators are facing more challenges and difficulties to grow mushroom due to inconsistent environmental conditions. Controlling and monitoring of environmental quality in mushroom cultivation is an important factor for high mushroom production. Therefore, this study was initiated to examine the suitability and growing performance of P. pulmonarius in indoor environmental condition. For this, the experimental design was followed by two different procedures as characterization and optimization of the indoor environment. Characterization procedure was conducted by mushroom cultivation in five different environmental conditions including from System 1 to System 5. The substrate for mushroom growing was prepared by mixing of sawdust, rice bran and agricultural lime for the all cultivation systems and spawn was inoculated. After completing mycelium colonization the experimental mushroom cultivations were conducted by System 1 to System 5. System 1 was the natural indoor environment whereas from System 2 to System 5 were the indoor humidifying environment with or without ventilation. The lowest mean indoor temperature and the highest mean humidity was found in System 3 which showed significant results with all other systems. The highest morphology and outstanding moisture containing fruitbodies were also found in System 3. The highest 98.4% primordial initiation and 98.6% mature fruitbodies formation with the lowest 1.4% dead primordia were found in System 3. The lowest 30.2% primordial initiation was found in System 1. The lowest 43.1% and 42.4% mature fruitbodies and the highest 56.9% and 57.6% dead primordia were found in System 4 and 5 respectively. The highest bio-efficiency (73.6%) of yield was achieved in the cultivation of System 3. The optimization procedure was conducted under two different environmental conditions as named System 6 and System 7. System 6 was followed by the procedure of System 3 with additional numbers of the humidifier, ventilation, and substrate bags. For this, the humidifiers and ventilations were applied by one combined and five individual treatments to optimize the humidifying duration and cultivation procedure. On the other hand, outdoor cultivation was conducted as System 7 for comparison study. The optimized configuration was found as the application of 15 mins humidifying treatment and followed by 15 mins interval period for each humidifier. The lowest temperature and highest humidity were found in System 6.The morphology and moisture contents of fruitbodies were found significantly high in System 6, where the total yield was found 261.8 kg which was 140.3 kg higher than System 7. The temperature showed significant negative correlation and the humidity showed significant positive correlation with the morphology and moisture contents of fruitbodies.
