Evaluation of Different Substrates for Yield and Yield Attributes of Oyster Mushroom (Pleurotus ostreatus) in Crop-livestock Farming System of Northern Ethiopia

Abstract

Background:In Tigray region of Ethiopia there is high rate of malnutrition which is severely affecting productivity of households. Cultivation of edible mushrooms can help to diversify income and mitigate malnutrition in the region. Aim:A laboratory experiment was carried out at Aksum University, northern Ethiopia aimed at evaluating the yield and yield attributes response of oyster mushroom to five types of substrates namely cotton seed hull, teff straw, barley straw, sesame stalk and sawdust. Methods:The experiment was set up in a Completely Randomized Design (CRD). Results:Findings of the experiment revealed that the type of substrate significantly (P≤0.05) affected days to mycelium invasion, days to pinhead formation, days to fruiting bodies formation and yield of Pleurotus ostreatus. Cotton seed hull was fastest in days to mycelium invasion with 15.66 days although in statistically parity with teff straw, barley straw and sesame stalk. Besides, cotton seed hull gave shortest days to pinhead formation, and days to fruiting bodies formation with 20.33 and 22.33 days respectively. The highest yield of 2170.33 gm kg -1 of substrate was obtained at cotton seed hull followed by barley straw which gave 1486.90 gm kg -1 of substrate and Teff straw which gave 1264.74 gm kg -1 of substrate. Conclusion:The experiment highlighted that cotton seed hull and barley straw can be used for mushroom production in the study area.

Cultivation of Different Oyster Mushroom (Pleurotus species) on Coffee Waste and Determination of Their Relative Biological Efficiency and Pectinase Enzyme Production, Ethiopia

“…This may be due to the difference in the type of substrate used and the type of species and/or the nature of strain employed. These results agree with the findings of Tekeste et al [ 24 ] who showed the variations of mycelia colonization in oyster mushroom with the chemical composition of different substrates.…”

Pruning Wastes From Fruit Trees as a Substrate for Pleurotus ostreatus

“…B.E.% was similar to that reported in most studies (Familoni et al, 2018;Masevhe et al, 2016;Tekeste et al, 2020;Tisdale et al, 2006;Zervakis et al, 2013). Consistent with the literature, substrates composed of pure wood were less efficient than those composed of mixed hay-wood.…”

Evaluation of Millet Straw (<i>Elusine coracana</i>) with the Supplement of Cotton Seed Waste for Cultivation of Oyster Mushroom (<i>Pleurotus ostreatus</i>)

“…According to Gume et al, [13] all the treatments they tested showed 3.73 to 5.13 days for primordial initiation after mycelia running. Tekeste et al [23] indicated that different substrates had valuable effects on duration to primoridial induction ranging from 23.33 on cotton seed hull to 29 days for saw dust, which was longer than the results of this study.…”

“…The fastest complete mycelia colonization date was recorded on T10 (10 days) while the slowest complete mycelia colonization date was recorded on T1 (20 days) (Table 2). Tekeste et al, [23] colonization of the different substrates were completed from 15.66 to 20 days of inoculation. Slightly longer mycelia colonization was reported by Tsegaye [24], who indicated that complete myclial invasion of the whole substrate with 20±6 in the mixture of cotton waste and teff straw.…”

“…The total fresh weight of mushroom recorded in this study was by far greater than the results reported in the literature. Nasir et al, [28] indicated 403 g of fresh mushroom from date palm 25%+wheat straw and cotton waste 75%, which was the highest and date palm 100% gave 185.75g which was the least; Tekeste et al [23] reported the highest yields from cotton seed hull and the least from saw dust. The highest total yields of the fresh mushroom in this study may be due the different mixing ratio of the millet straw and cotton seed waste which optimized the availability of nutrients in the substrate mixture.…”
