Promotion of tomato growth by Trichoderma sp. under shade mesh conditions

Chemical fertilizers are frequently used in agriculture with harmful effects on ecological components, so the use of microorganisms as growth regulators is an agricultural practice increasingly today. The aim this research was to evaluate Trichoderma sp. regulator tomato plants. isolated from soils grown solid PDA medium for morphological characterization fungus. An experiment analyse interaction between and shade mesh conditions established, where: T1 = sp.; T2 without (fertilization recommended crop applied); T3 T4 mesh. Several variables were evaluated plants fruits. macroscopic characteristics showed mycelium a cottony morphology dark green coloration, microscopic fungus conidiophores branch, phialides ovoid ellipsoid conidia. Interaction had significant effect plant height, number flowers fruits, greater values Regarding evaluation fruits differences found weight, diameter, length, colour (L a* value) but not b* value.
