| Summary: | The growth of a commercial strain of the Pleurotus ostreatus fungus in different substrate combinations was evaluated and in this way determine the treatment with the best efficiency and performance. The substrates evaluated were corn husk (Zea maiz), almond leaves and wood sawdust. The substrates were immersed in water with 20% sodium hypochlorite for 24 hours in 100 L tanks, subsequently, water was changed twice and 4 kg of quicklime was added for every 100 L of water. 1.0 Kilogram (Kg) of each of the substrates was prepared. The substrates were placed in transparent plastic bags with a capacity of 1.5 kg and seeded with 50 g of the prepared inoculum (5%). The substrates were incubated at 27 ° C and in total darkness, until the mycelium covered all the material. Mycelial growth, time of appearance of primordia, weight of carpophores, biological efficiency and yield were evaluated. In total, 1,792 grams were obtained in total, distributed as follows: 634 grams in treatment 1 (M-Corn 100%), 578 grams in treatment 2 (A- Sawdust 100%), 0 grams in treatment 3 (AL- Almond) 0 grams in treatment 4 (AL- A 50% Almond- 50% Sawdust) 580 grams in treatment 5 (MA 50% Maize- 50% Sawdust) and 0 grams in treatment 6 (AL-M 50% Almond- 50% Corn). In treatments 3, 4 and 6 the death of the mycelium was evidenced. |
