Abstract: Mushrooms are fruiting bodies of fungi and they are capable of degrading agro-wastes. Most of the edible fungi produce the enzyme complexes which degrade cellulose, hemicellulose and lignin in agricultural wastes and industrial byproducts. By growing mushrooms on these, results in high valued edible mushrooms with appreciable flavor and better nutritive values. Evaluation of pink oyster (Pleurotus eous) and milky (Calocybe indica) mushroom growth and yield on paddy straw amended with secondary-micronutrients (Calcium, Magnesium, Iron and Zinc sulphate) and study of biochemical changes during the growth at different stages was carried out. Sulphate forms of magnesium at 1 and 2 percent enhanced the mycelial growth of P. eous and C. indica respectively. Higher concentration of iron and zinc sulphates (4 and 6 per cent) inhibited the growth of P. eous and C. indica. The Pleurotus eous and Calocybe indica grown on secondary-micronutrients amended substrates showed higher ash content as compared to control. Calcium, magnesium, iron and zinc content of mushrooms was increased by calcium, magnesium, iron and zinc sulphates amendments to substrate. Cellulase, Laccase and Lignin peroxidase activities of P. eous and C. indica were higher in magnesium sulphate and calcium sulphate amended paddy straw. Higher yield of P. eous and C. indica was obtained in MgSO4 and CaSO4 amended paddy straw with bioefficiency of 113.50 and 527.50 percent respectively.
