Influence of different nitrogen rich supplements during cultivation of Pleurotus florida on corn cob substrate

Abstract

The cultivation of white rot edible fungus Pleurotus florida was performed in polybags. The corn cob was employed as basal substrate while eight different additives such as urea, ammonium sulphate, gram flour, soybean meal, ground nut cake and molasses were used with corn cob. Three different levels of variable combinations with corn cob were evaluated in response to different parameters of mushroom viz., mycelial growth, spawn running, primordial initiation, fruit body yield and its biological efficiency. Each additive at different combinations showed variable impact on the different stages of mushroom life cycle. The primordial initiation was observed for the first time during 20.2-35.1 days. The biological efficiencies in every supplemented set were increased over un-supplemented control set. Increasing the level of additives, the biological efficiency was negatively affected at higher levels. The cotton seed cake was found the best supplement producing 93.75% biological efficiency while soybean meal was the second best additive producing 93.00% yield. The highest growth rate, rapid mycelia run, early primordial initiation, highest yield and biological efficiency were recorded in the combination of corn cob and cotton seed cake at 2% (98 + 2) level.

Lignocellulosic Wastes Used for the Cultivation of Pleurotus ostreatus Mushrooms: Effects on Productivity

“…In this study, the best results were obtained at C:N ratios of 19.00 and 22.00. Other studies also have reported a positive correlation between growth and low substrate C:N ratios (Philippoussis et al 2001;Stamets 2005;Narain et al 2008).…”

Reuse of degraded Pleurotus ostreatus (Jacq.) P. Kumm. substrate by supplementation with wheat bran. Quantitative parameters

“…Gea et al (2009) working on specific substrates for growing P. ostreatus added supplements prepared from denatured soy flour and other organic protein sources, and reached BEs of 70.6%. With the same species, Naraian et al (2009) advise to use corncob substrates with chemical supplements (urea and ammonium sulphate) and biological supplements (chickpea flour, soybean meal, groundnut cake, mustard cake, cottonseed cake, and molasses) at low concentrations (0.5 and 2%) to improve BE. Fanadzo et al (2010) evaluated the BE with various substrates (WS, corn stover and H. filipendula and supplements (corn bran and cottonseed) in P. sajor-caju and P. ostreatus , showing that WS obtained higher BEs (71%) than with corn stover (40%) and H. filipendula (35.4%) in the species P. sajor-caju .…”
