    Fungi are widely distributed throughout the world, there are approximately 10,000 species, of which only 10% are edible fungi cultivation has become a popular activity, and is an important agricultural product worldwide. In Ecuador oyster mushroom production is minimal and that it is used for consumption of the communities that produce it, and sends it over to Quito for a company is sold. Some of the substrates used for growing these mushrooms are the straws of barley, wheat, rye, oats, rice and sorghum, Some growers add products or additives that apparently improve the soil and provide increased production are few studies that have done on cereal straw for oyster mushroom cultivation also include the secrecy of the few producers by not providing reliable technical information, making this crop a mystery why this research is to determine the more efficient treatment of barley chaff that meets the fundamental characteristics that must be present in order to develop the cultivation, efficiently and profitably. The objectives in this research were to determine whether the application of bran supplement influences the production of edible mushroom cultivation. Select the percentage of mycelium inoculation efficient substrate edible mushroom cultivation. Determine if the whole barley chaff or chopped influences the production of edible mushroom cultivation. Determine which of the treatments you get higher yield and production of edible mushroom. Perform an economic analysis, benefit / cost of cultivation. This research was conducted in the parish of St. Anne Pifo industry, was used oyster mushroom mycelium in different doses, barley straw and cereal bran as substrate and supplement, we used a block design in factorial arranged. The main conclusions obtained in this research were: The response of the substrate based on barley straw ( FA) in different yield components evaluated were different, yielding the best answers on the A1 (chopped straw), which presented the best performance with a net weight of 126.6 g fresh per case in this trial. In mushroom cultivation was not the best choice based nutritional supplement use bran cereal (B2) for their excellent response obtained with a net weight of 135.8 g fresh. Efficient amount of inoculation for the fungus mycelium oyster type is 30 g, its best performance in fresh weighing 108.4 g per sleeve. The most important independent variables that contributed to increase the net weight of fresh oyster mushroom was gross weight type fresh and biological efficiency. The most important variables that reduced performance were: days incubation and mycelial contamination. According to the economic analysis was the best treatment T5 (A1B2C2), presenting the highest net profit of $ 0.16., A cost benefit ratio (RB/C) at $ 1.12 USD and one (RI/C) $ 0.12 USD, this means that for every dollar invested recover $ 0.12 USD
