Effects of Vermicompost on Quality of Paddy Straw Mushroom (Volvariella vovacea) by Short Stack

Abstract

Vermicompost is produced of composting process using earthworms and contained nutrients-rich organic fertilizer. The experiment aimed to study the effect of vermicompost on quality of paddy straw mushroom cultivation by a short stack. The different concentrations of vermicompost (0, 20, 40, 60, 80 and 100 percents by weight paddy straw mushroom) were tested. The experimental design was complete randomized designs (CRD) during April to June, 2016. The result showed that, in April 2016, the temperature and humidity inside were 38-40 °C and 65-75 %, respectively in April 2016. The mycelial growth was grown slowly taken about 5-7 days. While, the mycelial growth in June 2016 was grew faster than in April. All of the experiments were showed the mycelium increases within 3 days. The temperature and humidity inside were 35-38 °C and 75-80 %, respectively. The ratio at 40 % of vermicompost by weight paddy straw mushroom gave the highest of yield of fruiting body (444.01 g/stack), number of fruiting body/stack (36.67), number of button-shape stage/stack (4.67), and number of egg-shape stage/stack (32.00) of paddy straw mushroom cultured by short stack. All of the ratios were significantly different when compared with control. While, the number of button-shape stage/stack and percentage of button-shape stage/stack were showed non-significantly different between control and treated vermicompost.
