Effect of Chemical Supplementation on the Yield and Biological Efficiency of Pleurotus sajor caju Grown in Three Different Lignocellulosic Wastes in Chhattisgarh, India

In recent years the mushroom technology has traveled far a head. The domestication of various mushroom species has been tried globally, many of which are now commercially cultivated for food as well as medicinal purposes for an amateur and professional cultivator. The production of mushroom has become important factor, which does not promote the growers. The important priority of profession is to maximize the production of mushroom by using various techniques. Different concentration of carbon sources i.e. lactose (1.0%, 2.0% and 3.0%), nitrogen sources i.e. peptone (1.0%, 2.0% and 3.0%), inorganic chemicals i.e. Mgso₄ (1.0%, 2.0% and 3.0%), vitamin sources i.e. vit. B-complex (100, 200 and 300 mg/l) and growth promoter i.e. EDTA (0.1%, 0.2% and 0.3%) were screened to determine the most suitable concentration for better yield of Pleurotus sajor caju. Three lignocellulosic agricultural waste material i.e. wheat straw, paddy straw and leman grass straw used for cultivation of Pleurotus sajor caju It was found that carbon source and inorganic chemical gave maximum yield and biological efficiency in 2.0% concentration in wheat straw. On that basis lactose and Mgso₄ were proved superior carbon source and inorganic chemical, respectively. peptone, the semisolid protein as nitrogen source gave maximum yield and biological efficiency in 3.0% concentration in lemon grass straw while in case of growth promoter it was observed maximum in 0.2% concentration in wheat straw. vitamin B-complex gave maximum yield and biological efficiency in 300-mg/l concentrations in wheat straw, among the three lignocellulosic agricultural wastes material used as substrate, best growth and high yield of Pleurotus sajor caju was obtained in wheat straw.
