The present study investigated the macro-micro nutrient, sugar and vitamin C content and some yield parameters in 3 miniature tomato cultivars (Black Zebra Cherry, Window Box Yellow and Sweet Pea Currant) grown with three different fertilizer applications: Application 1 (App. 1): Base fertilization with DAP; Application 2 (App. 2): Base fertilization with DAP + chemical fertilizer; Application 3 (App. 3): Base fertilization with DAP + organic fertilizer + biochemical fertilizer on a farmer's field. The study was conducted with a factorial design comprised of 9 treatments, with 4 replications of 40 plants per treatment. Study findings demonstrated that there were significant differences among the cultivar yields and fertilizer applications, where applications 2 and 3 led to significant increases in yield parameters. Furthermore, especially the fertilizer applications 2 and 3 provided the best results in most studied parameters.
