Abstract
The effect of Trichoderma-based biofertilizer applied to cabbage farms on the abundance of collembolans in cabbage farms was assessed, this being the first study conducted on this subject. Emphasis was given on collembolans mainly because they include fungivores and share the same ecological requirements with Trichoderma. Farmer’s field experiments were conducted in Barangays Mamala 1 (Site 1) and Sampaloc 1 (Site 2) in Sariaya Quezon to determine possible differences in abundance between Trichoderma-enhanced and conventional cabbage plots. Soil samples were collected at 20, 40 and 60 days after planting (DAP) from both sites and run through Berlese-Tullgren funnel to extract arthropods. Four collembolan species were identified, namely: Isotomurus parabalteatus Gapud, Willowsia sp., Seira sp. and Xenylla sp. Results showed that for both sites, the total abundance of collembolans was higher in Trichoderma-treated (Site 1: n=1341, Site 2: n311) than in conventional plots (Site 1: n=399, Site 2 : n=76). However, results varied between sampling periods depending on the prevailing physical conditions, thus showing no significant difference for collembolans. Therefore, Trichoderma may enhance the population of collembolans given optimal conditions but beneficial effects in maintaining such populations may be diminished under suboptimal conditions.
