There is a significant interest in the cultivation of oyster mushrooms (Pleurotus ostreatus) as nutritious food, with the rise in its consumption. Thus, there is a need to compare different low-cost available substrates for its productivity in Afghanistan. In the present study, two substrates wheat straw and tree leaves along with their combination (1:1) as a single substrate were tested based on 10, 20 and 30 grams of spawn (wheat seeds mycelium growth). And the growth rate of fruiting bodies (fresh weight) was used for statistical analysis. When the wheat straw with 30 gr of wheat seeds spawn was used, resulting in the highest yield (348 gr/Kg substrate). While the growth of the mushroom showed better results (273 gr/Kg substrate) on mixed substrates with 30 gr of spawn as compared with the third substrate which consist of tree leaves+30 gr of wheat seeds growth spawn (111 gr/Kg substrate) indicating the lowest yield for P. ostreatus. This study concluded that the wheat straw substrate had affected significantly positive on fresh weight, and its yield was higher when the maximum dose of spawn was applied. To the best of our knowledge, this is the first study that evaluated local substrates for cultivation of the mushroom in Afghanistan.
