These features make oyster mushroom cultivation suitable for the beginners and the mushroom farmers with low-tech equipment.
It is one of the most suitable fungal organisms for producing protein-rich food (mushroom) from various agricultural or forest wastes without composting.Ĭultivation of oyster mushroom ( Pleurotus spp.) has increased greatly throughout the world during last few decades due to the ease of its cultivation on various lignocellulosic wastes, shorter growth time, no need of composting of its substrate, demand for a few environmental control, high yield potential, high nutritional values as well as medicinal values. The fruit bodies of the genus Pleurotus are generally referred to as ‘oyster mushroom.’ It is a lignocellulolytic fungus of Basidiomycetes and grows naturally in the temperate and tropical forests on dead and decaying wooden logs, sometimes on dying trunks of deciduous or coniferous woods or decaying organic matter. The results of the present study indicate that biomass of water hyacinth weed can safely be used with rice straw (1:1) as the alternate substrate for the cultivation of Pleurotus species to reduce the cost of production of protein-rich oyster mushroom and to recycle the vast amount of nuisance weed in an eco-friendly way. Minerals (Fe, Cu, Zn) and toxic elements (Pb, Cd, As) though flow from the substrate of RS + WH (1:1) to the mushrooms do not accumulate at a toxic level. No significant differences are observed between the nutrient qualities of the oyster mushrooms that grow either on rice straw or on water hyacinth supplemented rice straw (1:1). The yield of mushrooms significantly increases with their 1:1 combination (RS + WH 1:1), especially in the first flush.
To obtain a cost-effective production of oyster mushrooms, invasive aquatic weed water hyacinth has been tried out as a substrate in different combinations with rice straw (1:1, 1:2, 2:1) for the cultivation of Pleurotus species.
