Cultivation of blue oyster medicinal mushroom (Hypsizygus ulmarius (Bull.: Fr.) Redhead) on various agricultural residue for growth, yield and nutrient content

Abstract

The research experiment of blue oyster mushroom was carried out to investigate the cultivation on different agricultural and weed substrates. Among, the seven treatments agricultural substrates such as (wheat straw, banana leaves, sawdust, bajra dry stem and bamboo leaves) and weed substrates (dood grass and sarpat) replicated six times under the complete randomized design. The data were recorded and analyzed at the different stages of growth, total yield, biological efficiency as well as the protein and carbohydrate content of the mushroom. The data was observed from the 1st, 2nd and 3rd flushes of all the treatments. The objective of this study was to evaluate the performance of best agricultural and weed substrates on the growth, maximum yield production with highest biological efficiency and nutritional content of mushroom. The best substrates for spawn run, primordial initiation, primordial stage to harvesting was recorded (wheat straw + banana leaves) in (1:1). The maximum yield was recorded in T3 ((wheat straw + banana leaves) (936.6 gm) with the highest biological efficiency and minimum yield were recorded in T5 (wheat straw + saw dust) (665 gm) as compared with the wheat straw (control). The maximum protein and carbohydrates content were recorded in T3 (wheat straw + banana leaves) (35%) and (25.33%) in comparison to the other treatments. The revealed data show that banana leaves substrates in combination with wheat straw proved to be best and weed substrates also good for cultivation of Hypsizygus ulmarius.
