Abstract:
Throughout history, people have become aware of the possibility of using plants, both as raw materials in food and for
treating various medical conditions. Also, along with the evolution of mankind, the methods of using various species of
aromatic and medicinal plants have been attained. At the same time, a multitude of information about the curative
effects of plants, as well as the level of toxicity of some species, has also been accumulated. The objective of this
research was to establish the effects of row spacing and foliar fertilization on fresh grass, seeds and essential oil
production of two fennel varieties: Foeniculum vulgare var. vulgare and Foeniculum vulgare var. dulce. The field
experiment was set in Research Station – Ezăreni Farm University of Life Sciences, Iasi, in three years, 2020, 2021 and
2022. The results showed a significant impact of both rows spacing and foliar treatments on the production values. A
genetic influence of variety can also be distinguished, the fresh grass, seed and essential oil production showing higher
values in case of Foeniculum vulgare var. vulgare, compared to Foeniculum vulgare var. dulce. In case of both fennel
varieties, the highest production values were obtained with 50 cm between rows and complex foliar treatment (amino
acids, macronutrients and micronutrients).
