This study aimed to investigate the performance of oyster mushrooms on different substrate combinations, including rice straw alone, rice straw and water hyacinth (1:1), rice straw and water hyacinth (1:2), and rice straw and water hyacinth (2:1), in Pokhara, Kaski from April to June in 2022. A Completely Randomized Design with four replications was used to analyze the growth and yield parameters of the four different substrate combinations. The data were analyzed using R-Studio. Highly significant results (P > 0.001) were found in all growth and yield parameters. The best response in terms of days to colonization, pinhead formation, and total crop duration was observed with rice straw alone (11.5, 13.25, and 54.00 days, respectively). The stipe length, pileus diameter, and fruiting body per bunch had their highest values (3.44 cm, 5.21 cm, and 34.50 cm, respectively) with rice straw alone, followed by rice straw and water hyacinth in a 2:1 ratio (3.05 cm, 4.63 cm, and 34.25 cm, respectively). The maximum total fresh yield of mushrooms (1.53 kg with 153.16% BE) was observed for rice straw alone, followed by rice straw and water hyacinth in a 2:1 ratio (1.17 kg with 116.5% BE), while the poorest yield (0.76 kg with 76.38% BE) was observed in the case of rice straw and water hyacinth in a 1:2 ratio. The highest profitability was observed for mushroom production using rice straw alone with a B:C ratio of 1.24, followed by using rice straw and water hyacinth in a 2:1 ratio (1.03), while the lowest B:C ratio was observed for rice straw and water hyacinth in a 1:2 ratio (0.74). Overall, the best treatment was found to be rice straw alone, followed by rice straw and water hyacinth in a 2:1 ratio. These results suggest that using rice straw alone or in combination with water hyacinth in a 2:1 ratio can be an effective strategy for oyster mushroom cultivation.
本研究旨在调查2022年4月至6月在卡斯基博克拉，平菇在不同基质组合上的表现，这些组合包括单独的稻草、稻草与水葫芦（1:1）、稻草与水葫芦（1:2）以及稻草与水葫芦（2:1）。采用完全随机设计，重复四次，以分析四种不同基质组合的生长和产量参数。数据使用R-Studio进行分析。在所有生长和产量参数中均发现极显著结果（P > 0.001）。单独使用稻草时，在定殖天数、针头形成天数和总作物生长天数方面观察到最佳响应（分别为11.5天、13.25天和54.00天）。单独使用稻草时，菌柄长度、菌盖直径和每束子实体数量达到最高值（分别为3.44厘米、5.21厘米和34.50个），其次是稻草与水葫芦比例为2:1时（分别为3.05厘米、4.63厘米和34.25个）。单独使用稻草时，平菇的总鲜产量最高（1.53千克，生物学效率为153.16%），其次是稻草与水葫芦比例为2:1时（1.17千克，生物学效率为116.5%），而稻草与水葫芦比例为1:2时产量最差（0.76千克，生物学效率为76.38%）。单独使用稻草进行平菇生产时，观察到最高的盈利能力，投入产出比为1.24，其次是稻草与水葫芦比例为2:1时（1.03），而稻草与水葫芦比例为1:2时投入产出比最低（0.74）。总体而言，最佳处理方法是单独使用稻草，其次是稻草与水葫芦比例为2:1。这些结果表明，单独使用稻草或以2:1的比例与水葫芦混合使用，可能是平菇栽培的有效策略。
