ABSTRACT
The present study was carried out in order to evaluate the effect of sugar cane baggasse on growth and recovery of trichoderma. This study was conducted in Crop Science Laboratory, Faculty of Agriculture, University of Benin, Benin city. Sugar cane bagassewas obtained from an open market Benin City, sun dried and stored in jute bag.Soil sample were collected from the Department of Crop Science. The experimental design used was completely randomized design (CRD), the data collected were subjected to the analysis of variance (ANOVA). The means were separated with the least significance difference (LSD) method described by the turkey’s 95% confidence interval. The result obtained from the study shows there was significant difference among the various moisture levels, except at moisture level 15cm, 20ml and 25m which were the same. The highest mycelia growth rate (4.15cm) was recorded for 10ml treatment. This was followed by the control (4.118cm), 15ml (3.958cm), 20ml (3.686cm) and 25ml (3.574cm). The highest mycelia growth was recorded on day 21 (6.784cm), but was not significantly different from mycelia growth of days 20 (6.724cm), day 19 (6.628cm), day 18 (6.496cm).The enzymatic activities was highest (25%) at the moisture level of 25% while it was lowest (0.0537) at a moisture level of 75%. The study further concluded that sugar cane bagasse can serve as a good source of Trichoderma spp carrier which can be used as biofertilizer in plant agriculture. Also, sugar cane bagasse could be a xii material of choice for designing a new medium for fungi which could replace expensive media such as potato dextrose agar (PDA), Sabouraud dextrose agar (SDA), or cornmeal agar (CMA) as it is readily available in large volumes and also meets the requirements for fungal growth.
