Melissa officinalis L., commonly known as lemon balm, is a melliferous species from the Lamiaceae family, known and used since antiquity for its medicinal properties. The study investigated the impact of mineral fertilization and planting distance on yield and associated technological relationships in lemon balm cultivation. The bifactorial experiment included three levels of nitrogen fertilization (N0, N30, N60) and two planting densities (50/30 and 60/30), arranged in a randomized block design with four replications. Fresh and dry biomass yields were determined, along with the contribution of each factor to total production. Statistical analysis focused on assessing the significance of differences using ANOVA, as well as on linear correlations among factors and regression coefficients, with the aim of identifying predictive relationships between technological inputs and plant response. Preliminary results highlight a significant influence of mineral fertilization on yield, enhanced by optimal planting densities, with relevant interactions between factors. Calculated correlations indicate direct relationships between fertilization level and biomass performance, while regression models outline predictive trends useful for developing sustainable cultivation technologies.
