Mycelial growth rate and yield of oyster mushroom – Pleurotus ostreatus fruitful part (Jacquin: Fr.) Kumm at different temperatures

Abstract

This research examined oyster mushroom production possibilities including mycelium and compost preparation, investigating temperature effects on mycelial growth and mushroom yield. Mycelium cultivated on PDA media transferred to sterilized wheat grains then composted beech sawdust and hay (1:1 ratio). Alternative compost compositions used wheat straw with soybean, corn stems, or sunflower stems. Mycelium which was growing at an average temperature of 20 °C after 15 days was ready for the next grafting, while the mycelium, which was kept at 4 °C for the same period, had very slow growth rate. Summer seeding yielded 17.76% while autumn seeding produced 7.2% relative to wet substrate weight. Temperature around 19.96 °C proved ideal for mycelium and mushroom growth with optimal yield expectations.
