Substrate evaluation for the growth of Pleurotus ostreatus mushroom

The type of substrate is a critical factor influencing the growth and yield of oyster mushroom (Pleurotus ostreatus). Seven substrates, namely wheat straw, paddy straw, maize straw, jowar straw, soybean straw, green gram straw, and black gram straw, were evaluated for their effect on oyster mushroom productivity. Among these, the highest yield was observed on soybean straw (815.66 g/kg straw) with a biological efficiency (B. E.) of 81.56 %, followed by yield on wheat straw (721.33 g/kg straw) with 72.13 % B. E. The lowest yield was recorded on maize straw (605.66 g/kg straw) with a B. E. of 60.56 %.
