Comparative Efficiency Of Various Substrates And Supplements On Growth Behaviour And Yield Potential Of Pleurotus flabellatus

Abstract

An experiment was conducted to study the comparative efficiency of various substrates viz, wheat straw (Triticum aestivum l.), paddy straw (Oryza sativa l.), corn stalk (Zea mays l.) and typha leaves (Typha angustifolia) and different supplements such as wheat bran, rice bran, neem cake and fenugreek bran on growth behavior and yield potential of oyster mushroom (pleurotus flabellatus). In these investigations higher mushroom yield with biological efficiency (BE) of 86.6 percent was obtained from wheat straw followed by paddy straw (63 per cent biological efficiency). Wheat straw was further used as a substrate for different supplements observation. Wheat bran was recorded significantly superior supplement than other supplements and its biological efficiency was 95 per cent. The spawn running, premordia initiation and harvesting of first flush were also early in wheat bran supplemented substrate where it completed in the 13 days, 17 days and 21 days respectively.

Impact of Inorganic Chemicals on Growth and Yield Potential of Pleurotus sajor-caju

“…Khare et al (2007) observed that the species P. sajor caju and P. florida grown on wheat straw substrates supplemented with grain flour, wheat bran increased yield of the mushroom as compared to control. Gautam and Ram (2007) studied the effect of wheat straw and different supplements such as wheat bran, Rice bran on growth behavior and yield potential of Oyster mushroom.…”
