Abstract

Trichoderma mass production requires the appropriate media, so the first step is necessary to identify the substrates which are appropriate, inexpensive, stable, and easily available. The purpose of this study was to evaluate the effect of agricultural waste corn straw, rice straw and bagasse against fungal radial growth activity of Trichodema viride. The study was conducted with one control and three treatments. The control was without the addition of agriculture waste; the three treatments were with the addition of corn straw powder substrate, rice straw powder substrate, and bagasse powder substrate. The observation of the research parameters included the macroscopic and microscopic observation of the fungus Trichoderma viride isolate and the measurement of growth rate during the incubation period, namely within 24 to 110 hours. The result of the measurement of the activity of radial growth of Trichoderma viride showed that the addition of the substrate bagasse was the highest in which the diameter was 74.96 mm, while the addition of corn straw substrate had the lowest in which the diameter was 32.69 mm. The highest rate of radial growth of 20.11 mm/day was produced by the addition of substrate bagasse, while the lowest rate, namely 11.42 mm/day,was the result of the addition of corn straw.
