Effect of Trichoderma harzianum in Different Media and Incubation Time on Color, pH and Conidia Density

The purpose of this study was to determine effect of Trichoderma harzianum in different media and incubation time on color, pH and conidia density. The method used was laboratory experiment using nested Completly Random Design (CRD). Twelve treatments were deferentiated on four media for Trichoderma harzianum growth namely was PDA or Potato Dextrose Agar (P1 ), molasses (P2 ), Panicum maximum cv. mombaca (P3 ) and Panicum maximum cv. mombaca + 5% molasses (P4 ) nested to three incubation times namely 4, 7, and 10 days. The incubation time was 0 days for comparison before the inoculation. The variables observed were color, pH and Trichoderma harzianum conidia density. The color was analized as descriptive analysis, while pH and conidia density were analized using Analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT). The results showed that Trichoderma harzianum had different color based on different media and incub
