“…The substrate was manually packed into bags and compressed by hand to achieve compactness. The packed substrates within the bags were allowed to be pasteurised at 100 °C for the period of 12 hours (Jang et al, 2003). This was done using the Marshall Fowler electrode steamer.…”

The use of supplemented agricultural waste in mushroom cultivation can be one of the environmentally friendly strategies for poverty alleviation. The study evaluated the performance of Pleurotus pulmonarius mushroom grown on maize stalk supplemented with varying levels of wheat bran (WB) and maize flour (MF). A completely random design was used for the experiments. It was observed that Pleurotus pulmonarius was significantly affected by varying levels of supplementation, as 20% WB supplementation encountered higher contamination. The lower supplementation levels gave significantly shorter colonisation period with better mycelial growth rate (MGR). The 2% MF, 2% WB and 4% WB gave significantly higher MGR and faster colonisation. The shortest pinning time (TP) was observed at the first flush with the minimum of 2 days. Higher supplementation levels gave maximum yield and biological efficiency (BE). With further increase of supplementation above a 12% WB and 14% MF, the BE and yield declined. Lower supplementation levels resulted in quicker colonisation period and improved growth rate, whereas high supplementation gave better production in terms of yield and BE. Therefore, for the purpose of maximum production, 12% WB and 14% MF may be recommended while for fast production time, 2% MF and 2% WB are recommended.

“…exposure to mineral oil fumes or mechanical damage to the partial veil (velum partiale) of developing primordia) that results in large hordes of malformed mushrooms with split stipes and with mis-shaped and -located lamella and caps and even convoluted pore-like hymenia ('lamellar dysplasia') on the pileus surface (Magnus, 1906;Stamets and Chilton, 1983;Flegg and Wood, 1985;Umar and Van Griensven, 1999;Noble et al, 2003). Elevated CO 2 concentrations lead in the agaric Pleurotus ostreatus and allies to size reductions and deformations of caps and to elongated stipes, eventually also to thickened plump short stipes with cap rudiments (Kinugawa et al, 1994;Jang et al, 2003;Kong, 2004). Slender elongated stipes with reduced pilei were also observed under higher CO 2 concentrations in cultures of other agarics including the edible A. bisporus (Stoller, 1952;Turner, 1977;Flegg and Wood, 1985), Flammulina velutipes (Kinugawa et al, 1994), Hypholoma capnoides (Gramss, 1978), and Lentinula edodes (Jablonsk y, 1981), as well as of stipitate-pileate polypores (Plunkett, 1956).…”

“…After the supplements were added and thoroughly mixed with the base substrates, 1 kg of the resultant substrate was packed into polypropylene bags (22.5 cm × 30 cm) in four replicates and compressed by hand until compactness was achieved. The bagged substrates were pasteurised at 60-65 °C for six hours (Jang et al, 2003) and allowed to cool to room temperature.…”

Improving the performance of mushroom in terms of high production and fast growth rate is essential in mushroom cultivation. In the present study the performance of Pleurotus ostreatus was evaluated using varying levels of wheat bran (WB) and maize flour (MF). The results indicated that Pleurotus ostreatus was highly influenced by different levels of supplementation, with 8% WB, 18% WB and 2% MF having higher contamination rate. The low levels of supplementation gave significantly better mycelial growth rate (MGR) and shorter colonisation period as observed that the control had highest MGR whereby 20% MF had lowest MGR. The pinning time (TP) was shortest at the first flush with minimum of 3 days (12% MF). The higher levels of supplementation showed maximum biological efficiency (BE) such as 14% MF, 12% WB and 14% WB. The yield was also higher at high levels of supplementation such as 20% MF and 8% MF being the exception in the lower levels. Based on the results it was observed that for fast production of oyster mushroom there is no need to supplement the maize stalk substrate but for improved productivity supplements can be added up to certain limits such as 14% MF and 12 WB. Keywords: biological efficiency; Pleurotus ostreatus; supplement; maize stalkPractical Application: The study will add to the pool of scientific knowledge relating to optimum substrate formulations (supplements) involving maize residues for Pleurotus ostreatus mushroom production. The results observed can be useful to small scale farmers who are willing to obtain good yield within minimal time at minimal cost with reduced contamination problems. Based on the results obtained, it is recommended that for fast production there is no need to add supplements on maize stalks but for improved production supplements can be added up to certain limits.
