Abstract

The effect of different growth substrates on nutritional (moisture percent, vitamin-c, carbohydrate, protein & ash) and mineral (Zn, Fe & Mn) contents of oyster mushroom (Pleurotus florida) was studied in the present investigation. In India, rice straw is mainly used as substrate for large scale mushroom production. But there are other materials also which are cheaper than rice straw and can also enhance the nutritional quality of mushroom. Thus, to explore those cheap and easily available growth substrates other than rice straw, the effect of seven substrates including rice straw (RS), newspapers (NP), coconut husk (CH), sugarcane bagasse (SB), wood residue (WR), sal leaves (SL) (Shorea robusta), and Lantana camara (LC) were studied solely and in combinations viz. RS+NP, RS+ SL, and NP + SL@ 1:3, 1:1, and 3:1 ratio. The results indicated that when the oyster mushroom grown solely on different growth substrates, mushroom harvested from LC had highest moisture (96.13%) and zinc (10.42 mg/ 100gdry weight/dw), whereas RS had highest vitamin-c (11.51 mg/100 g fresh weight/fw) and manganese (3.63mg/100gdw) content. Mushroom grown on SB reported maximum carbohydrate (43.96g/ 100g dw). Highest amount of protein (29.44g/ 100g dw) was obtained from SL. Among the different substrate combinations highest vitamin-c (11.50mg /100 g fw) and manganese (3.11 mg/100g dw) were reported from RS + NP (3:1); highest carbohydrate (38.17g/ 100g dw) from RS + SL (3:1); highest protein (26.46g/ 100g dw) from RS + SL (1:3); highest ash (10.96g/ 100g dw) and iron (18.87 mg/ 100g dw) from RS + NP (1:3).

Conclusion

Based on the studies of the present investigation it can be recommended that apart from our traditionally used rice straw other agro-wastes like sal leaves, Lantana camara etc. can also be used for small- and large-scale production of oyster mushroom maintaining all its nutritional parameters as high as rice straw.
