Respon Pertumbuhan dan Produksi Beberapa Varietas Jamur Tiram pada Kombinasi Media serbuk Limbah Pelepah Kelapa Sawit dan Serbuk Gergaji

Abstract

The purpose of research is to know the growth response and production of several varieties of oyster mushroom on the powder media of palm stem waste and sawdust. Research conducted in Sumatra mushroom oyster cultivation. The design used in this study is a Complete Random Design (CRD) factorial that is of 2 factors. The first factor is the composition of the planting media of palm oil and sawdust which is: M0:100% Sawdust, M1:100% oil palm stem powder, M2:75% oil palm stem powder + 25% sawdust, M3:50% palm oil release powder + 50% sawdust, M4: 25% Oil Palm release Powder + 75% sawdust and some varieties of oyster mushroom namely V1 (white oyster Mushroom), V2 (Red oyster Mushroom), V3 (Brown oyster mushroom). The study was conducted with 2 repeats. The Parameter of observation on the study is the percentage of baglogs covered by mycelium (%), the growth of mycelium on the substrate (cm), the age of the body of the fruit (DAI), Number of fruit body (fruit), diameter of the hood (cm2) The stem length of the fruit body (cm) and the wet Harvest weight (g). The results showed that the best treatment for the growth of mycelium and the age of fruit body in the media M1 and varieties V2 with the best combination of M1V2 namely 58.38 days formation of the first fruit body. As well as the diameter of the hood and the stem length of the M1 media and V3 varieties with the best combination of M1V3 is diameter 10.94 cm and the stem length 6.97 cm. While the number of fruit body parameters in the media M2 and varieties of V1 with the best combination M2V1 IE 24 white oyster mushroom fruit body, and the parameters of wet harvest weight on M4 media and V1 varieties with the best combination of M4V1 is with first and second total harvest is 261.63 g
