Influence of fertilization on wild nettle (Urtica dioica l.) and fennel (Foeniculum vulgare Mill.) yield

Climate change and the growing world population are affecting every human activity, especially agricultural production. The main goal is to produce adequate yields of high-quality plant material rich in nutritive value. One of the possible solution to solve the above-mentioned problems is the introduction of wild species into agricultural production. Wild species such as stinging nettle (Urtica dioica L.) and fennel (Foeniculum vulgare Mill.) are plant species that have a strong biological potential and nutritive value whether wild or grown under controlled conditions (cultivated). The aim of the present research was to test the influence of different fertilization treatments on the quality of wild nettle and fennel. A split-plot experiment was set with four fertilization treatments as factors – control (no fertilization), mineral fertilizer, organic fertilizer and a combination of mineral and organic fertilizers, set on both stinging nettle and fennel. Fennel experiment results showed a significant increase in the vegetation index under mineral fertilizer application, compared to other treatments. Both mineral and combination (mineral and organic fertilizer) resulted in higher yield. Stinging nettle experiment results showed a significant increase in vegetation index under mineral, organic and combination treatments application, compared to control treatment. Furthermore, the same results were obtained regarding stinging nettle yield. It can be concluded that the introduction of wild species such as stinging nettle and fennel into agricultural production can be successfully achieved and fertilizer application showed a positive effect on both vegetation index and yield.
