Efficacy of different spawn types on sawdust media

Abstract

An investigation was conducted to evaluate the efficacy of four different types of grain spawns viz; kurakkan (Eleusine coracana), maize (Zea mays), sorghum (Sorghum bicolor), and paddy (Oryza sativa) on oyster (Pleurotus ostreatus) mushroom production. Spawn types were based on their effects on mushroom solids (%), biological efficiency (BE %), size (g), number of sporophores, yield, yield ratio and substrate weight loss (%). Locally available kurakkan (Eleusine coracana), maize (broken) (Zea mays), sorghum (Sorghum bicolor), and paddy (Oryza sativa) were used for spawn production. The experiment was designed as a complete randomized design with three replicates. Four types of spawns were tested on a medium based on sawdust. The growing media (substrate) inoculated with kurakkan spawns showed the highest biological efficiency of 27.82± 0.12 (%) , mean yield of 52.94 ± 0.67 g, mushroom size of 7.73 ± 0.33 g and yield ratio of 23.19 ± 0.01. The harvests obtained from paddy spawn showed the highest mushroom solids of 9.97 ± 0.26 (g/100g of harvest). Highest mean numbers of sporophore (fruiting bodies) were noticed in the harvests obtained from sorghum spawn (7.67 ± 0.66). The kurakkan spawn significantly. Enhanced biological efficiency and increased size and yield, when compared with other spawn types viz; maize (Zea mays), sorghum (Sorghum bicolor), and paddy (Oryza sativa).

Effect of Different Saw Dust Substrates on the Growth and Yield of Oyster Mushroom (Pleurotus ostreatus)

“…The lowest time from stimulation to primordia initiation was observed in T 3 and T 2 (6.0 days). The highest time from stimulation to primordia initiation was observed in T 1 (8.0 days).…”

“…Cultivation of oyster mushroom has increased tremendously throughout the world because of their abilities to grow at a wide range of temperature and harvested all over the year [2]. Pleurotus have the ability to excrete hydrolyzing and oxidizing enzymes [3] which have capable of utilizing complex organic compounds that occurred agricultural wastes and industrial by-products [4] with broad adaptability varied agro-climatic conditions [5]. Pleurotus ostreatus demands few environmental controls, and their fruiting bodies are not often attacked by diseases and pests, and they can be cultivated in a simple and economic way [6].…”

Cultivation of Oyster Mushroom (Pleurotus HK-37) On Solid Sisal Waste Fractions Supplemented With Cow Dung Manure

“…Thus many agricultural and industrial wastes can be utilized for production of Pleurotus species as a substrate. Pleurotus have the ability to excrete hydrolyzing and oxidizing enzymes which have enabled them to flourish over a wide range of natural lignocellulosic waste materials (Pathmashini et al, 2008). Composted sisal decortications solid wastes were demonstrated to be a suitable substrate for cultivation of indigenous edible mushroom including Coprinus cinereus, Pleurotus flabellatus and Volvariella volvocea (Mshandete and Cuff, 2008).…”

Güve-Alev Optimizasyon Algoritması Kullanarak Pleurotus cornucopiae var. citrinopileatus Mantarı Ekstraksiyon Koşullarının Optimizasyonu

“…İstiridye mantarları Pleurotus spp., dünyada en çok üretilen üçüncü yenilebilir mantardır [3]. Bu mantarlar, hidrolize edici ve oksitleyici enzimleri salgılama [4] ve tarımsal atıklardan oluşan karmaşık organik bileşiklere ve endüstriyel yan ürünlere geniş bir dönüşüm adaptasyonu kabiliyetine sahiptirler [5]. Dolayısıyla, istiridye mantarlarının üretimi, bertarafı sorun haline gelen diğer organik atıkların yönetimine oranla daha az problem teşkil etmektedir.…”
