Abstract
Paddy straw mushroom (Volvariella volvacea) commonly known as the straw mushroom, in India, commonly referred to as âPual mushroomsâ, âPala chhatuâ in Odia belongs to Phylum-Basidiomycota, Class- Basidiomycetes, Order-Agaricales, Family-Pluteaceae and Genus Volvariella. It is being the third most important cultivated mushroom in the world and is well known for its pleasant flavour and taste. Different substrates and supplements were evaluated in this study to increase the biological efficiency. Four locally available substrates viz. paddy straw, pea straw, cotton waste and wheat straw and supplements viz. rice bran, wheat bran, chickpea powder, pea powder and pigeon pea powder were evaluated for the production of paddy straw mushroom. In evaluation of four locally available substrates for its cultivation, cotton waste substrate produced highest yield (734.8g and 796.2g per bed) and biological efficiency (14.7 % and 15.92 %) in both the cropping period followed by pea straw (12.96 % and 14.16 %), paddy straw (9.32 % and 12.68 %) and wheat straw (8.54 % and 11.32 %) respectively, in both the cropping period. Among the five supplements evaluated on paddy straw substrate, rice bran showed highest yield (821.0g per bed of 5.0 kg dry substrate) followed by wheat bran (791.3g), chick pea grain powder (743.0g), pigeon pea grain powder (704.3g) and pea grain powder (683.0g).
