Abstract: Cultivation of the oyster mushroom, Pleurotus ostreatus, on rice and wheat straw without nutrient supplementation was researched. The effects of straw size-reduction methodology and substance size, spawn inoculation level, and type of substrate (rice straw versus wheat straw) on mushroom yield, natural effectiveness, bioconversion efficiency, and substrate declination were determined. Two size reduction approaches, grinding and dicing, were compared. The ground straw yielded an advanced mushroom growth rate and yield than the hashed straw. The growth cycles of mushrooms with the ground substrate were five days shorter than with the diced straw for analogous particle size. Mushroom cultivation is a profitable agribusiness manifestation of non-conventional crops in being farming system can ameliorate the profitable status of the farmer. Mushrooms are the greatest source of protein, vitamins, and minerals and are anti-cancerous, anti-cholesterol, and anti-tumorous. Sawdust produced the topmost yield, natural effectiveness, and the number of fruiting bodies recommended as the best substrate for Oyster mushroom cultivation. The cultivation technology of oyster mushrooms is veritably simple and cheap. Theoretically, each crop takes 45 days under controlled conditions and hence there can be 8 crops per cycle. It's the 3rd largest cultivated mushroom in the World. China alone contributes 88 of the total world population. Oyster mushrooms can grow at a moderate temperature ranging from 20 to 300 C and moisture 55-70 for a period of 6 to 8 months in a time. It can also be cultivated in the summer months by furnishing the redundant moisture needed for its growth in hilly areas above 900m. Oyster mushroom is an economically profitable crop with high demand and supply patterns and exports. Its management is simple and easy to maintain in a restricted low ventilation room. Oyster mushrooms can be used in Women’s Empowerment, the women of the small village can make money by cultivating oyster mushrooms at their homes.
