Several waste materials can be utilised in a number of ways to generate income and create employment. Agriculture based waste materials can be used in the cultivation of edible mushrooms. Edible mushrooms contain proteins and B vitamins and help to lower cholesterol, prevent diabetes, improve bone health and boost immune system function. In this study, white oyster mushroom, Pleurotus ostreatus was grown on three different substrates: paddy straw, nut grass and newspaper. The aim of this study was to determine which substrate was best for the cultivation and production of white oyster mushroom. The parameters monitored in this experiment were growth rate, yield and biomass. The experiment was randomized and each substrate was replicated three times resulting in a total of nine experimental units. The nut grass substrate produced mushrooms with the highest values for growth rate; it was also the first substrate to be colonized by the white oyster mushroom mycelium. Nut grass also produced mushrooms with the most fruiting bodies at time of harvesting. The newspaper substrate produced pinheads first, but it performed the least among the three substrates. Paddy straw was deemed the most suitable substrate for cultivation since this substrate produced mushrooms with the highest yield (185g) and biomass (26.67g).
