Promoting the use of agricultural waste is one of the newly prepared water and environment friendly agriculture strategies in the Kingdom of Saudi Arabia (KSA). The objective of this research was to study the efficiency of cultivating oyster mushroom (Pleurotus ostreatus) on date palm wastes mixed with other agricultural wastes available in KSA. Four agricultural wastes were mixed with date palm leaves at different ratios, with two supplements and three spawn rates were used. Wheat straw mixed with date palm at ratio of 25 (date palm): 75 (agro-waste) showed the best results in most of the parameters measured. Corn meal was superior over wheat bran as a supplement in all treatments. Parameter values increased with the increase of the spawn rate of P. ostreatus. Treatments with date palm leave wastes contained higher carbohydrates and fibers. No significant differences were found among the fruiting bodies produced on the different agro-wastes studied for the different proximates analyzed. Analyses of metal concentration showed that potassium was the highest in all the treatments tested followed by Na, Mg, Ca, and Zn. This is the first study that reported the success of growing oyster mushroom on date palm leaf wastes mixed with other agro-wastes obtainable in KSA.
推广农业废弃物的利用是沙特阿拉伯王国（KSA）新制定的水和环境友好型农业策略之一。本研究的目的是研究在沙特阿拉伯可用的其他农业废弃物混合的椰枣废料上栽培牡蛎蘑菇（Pleurotus ostreatus）的效率。将四种农业废弃物与椰枣叶以不同的比例混合，使用两种补充物和三种接种率。在大多数测量参数中，椰枣：（75）/农业废物（25）的混合物显示出最好的结果。在所有处理中，玉米粉比麦麸作为补充物更优越。随着 P. ostreatus 接种率的增加，参数值增加。用椰枣叶废料处理的物质含有更高的碳水化合物和纤维。在所研究的不同农业废物上产生的子实体之间，对不同的近似值分析没有发现显著差异。金属浓度分析表明，在所测试的所有处理中，钾的含量最高，其次是 Na、Mg、Ca 和 Zn。这是第一项报道在沙特阿拉伯可用的其他农业废弃物混合的椰枣叶废料上成功种植牡蛎蘑菇的研究。
