ABSTRACT
This study was conducted to determine if the activity of trichoderma harzianum is affected by the addition of the substances rich in carbohydrate, protein and calcium. The study was conducted in Linabwan Norte, Aklan. The methodology of the study followed the undergraduate thesis of M. Teruel (1998). The statistical tools used in the study were the mean and standard deviation for descriptive statistical tools, and the t-test and One Way Analysis of Variance (One Way ANOVA), all set at 0.05 alpha level of significance, were used of inferential statistical tools.
The result of the study showed that there was no significant difference in the rate of decomposition when it is either treated or untreated with different substances. There was no significant difference in the rate of decomposition when it is either treated with lime, potato starch, or fishmeal. There was no significant difference in the initial and final heights of the compost piles before and after the addition of lime potato starch, and fishmeal. Among the substances used lime showed the fastest rate of decomposition.
