ENHANCING WHITE OYSTER MUSHROOM CULTIVATION THROUGH LIGHT STIMULATION USING WHITE LED

Abstract

This study aims to investigate the impact of different illumination durations on the yield of white oyster mushrooms cultivated in a controlled environment mushroom chamber, with a focus on the advantages of LED lighting over conventional lighting methods. The experiment considered various time exposures: 3, 6, 9, 12, 15, and 24 hours per day, while fluorescent light exposure for 12 hours per day served as the control group. Parameters such as mushroom weight, pileus diameter, stipe diameter, and stipe length were measured. Results indicated that the most significant fruiting bodies in terms of pileus diameter (105.76 mm) and stipe diameter (15.26 mm) were observed with a 15-hour illumination exposure. Conversely, the 12-hour exposure using fluorescent lamps resulted in the smallest pileus diameter, averaging 79.70 mm. Notably, a 3-hour exposure demonstrated the most substantial impact on yield, resulting in 182.4 g over two harvest cycles. In conclusion, treating white oyster mushrooms with white LED lighting can enhance productivity. This is primarily due to the excessive heat and higher light intensity generated by fluorescent lights, which can inhibit growth during the fruiting development stage. Therefore, adopting white LED lighting systems offers greater control over the ideal light intensity required for optimal mushroom growth.
