Growth and Yields of Three Tomato Strains of Lycopersicum Esculentum Mill With Various Dosages of Trichoderma Sp

By testing several F1 tomato lines, the genetic diversity of tomatoes can be observed for their agronomic characters and product. To increase fruit production, Trichoderma sp, a biological microbial material and plant growth stimulator, can be applied to tomatoes. The goal of this study was to track the growth and development of three tomato strains along with their interactions with Trichoderma sp. A completely randomized design was used in this study, with two factors and three responses, and the two treatments were repeated three times. The tomato strains were Servo F1, F2, and F3, and the Trichoderma sp dosages were 30 g/plant, 40 g/plant, and 50 g/plant. ANOVA was used to analyze the data, followed by a DMRT test at a 5% level. This study found that the F1 tomato strain was significantly taller, while the F3 tomato strain had a sweeter taste. Trichoderma sp at a dose of 40 g/plant accelerated the appearance of flowers and fruit diameter. The addition of Trichoderma sp at a dose of 40 g/plant in Servo F1 tomatoes increased the total number of leaves and the total weight per plant. Tomato vitamin C content was increased in the F1, F2, and F3 tomato strains with 30 g/plant Trichoderma sp. Keywords: Tomato, Trichoderma sp, strai
