Cultivation of Oyster Mushroom (<i>Pleurotus ostreatus</i>) on Sawdust

Abstract

A study was conducted to examine the effect of different types of spawns on oyster mushroom (Pleurotus ostreatus) production using sawdust. Locally available grains of kurakkan (Eleusine coracana), maize (broken) (Zea mays), sorghum (Sorghum bicolor), and paddy (Oryza sativa) were used for spawn production. Sawdust spawned with different types P. ostreatus spawns were examined for spawn running (mycelia development), pinhead formation and fruit body formation, mean yield, and biological efficiency. The experiment was setup as a complete randomized design with three replicates. The kurakkan spawn produced an acceleration of spawn running, pinhead formation, fruit body formation and increased yield, compared with other types of spawn viz.; maize, sorghum, and paddy. The fastest spawn running of 21 ± 1 days, pinhead formation of 35 ± 1 days, highest mean yield of 55.37 ± 0.67 g and maximum fresh mushroom yield percentage of 30.76 ± 0.01 were realized for kurakkan spawn.

Influence of substrates on the nutritional quality of Pleurotus pulmonarius and Pleurotus ostreatus

“…Spawn running was fastest in banana leaves substrates but the highest pileus diameter and stipe height were observed in mushroom from amended sawdust which took about four weeks for complete spawn running. Differences in rate of spawn running may be attributed to the size of the grains (Pathmashini et al, 2008).The suitability of amended sawdust agreed with the work of Shah et al (2004) who both advocated the effectiveness of sawdust in mushroom cultivation. Wheat straw substrate is one of the best substrates in Pleurotus ostreatus cultivation (Kumari and Achal, 2008) and the produce has average pileus diameter that is higher than the one obtained from amended sawdust.…”

Yield and nutritional composition of oyster mushroom strains newly introduced in Bangladesh

“…(3) Biological yield (g per bag), the whole cluster of fruiting bodies; economic yield (g per bag), cleaned fruiting bodies separated from cluster and dirty portion. (4) BE, biological efficiency: fresh weight of mushroom (g) per dry weight of substrate (g) × 100 (Pathmashini et al, 2008 contents, respectively (Ajonina et al, 2012). These authors observed differences in stalk length (2.43 to 3.24 cm) for P. ostreatus, whereas Monadal et al (2010) reported a decrease in the storage quality of the oyster mushroom with the increase of the pileus and stalk diameters.…”

“…Pathmashini et al (2008) recorded 276.87 g as the highest biological yield for strain PO2 in sawdust with kurakkan spawn.…”

“…The whole cluster of fruiting bodies was considered for biological yield measurement, and the cleaned fruiting bodies (separated from cluster by removing lower tough and dirty portion) were weighted to obtain economic yield . The conversion percentage (biological efficiency) was determined (Pathmashini et al, 2008) as follows: biological efficiency (BE) = (grams of fresh weight of mushroom/dry weight of substrate) × 100.…”

Leadership in Malaysian Paddy Farming

“…Second, they are often focused on improving the availability of services to recepients instead of providing ownership. Third, they are run so as to guarantee the provision of services to all beneficiaries within a community (Pathmashini, Arulnandhy et al 2008). …”
