Effect of Nitrogen Fertilization on THC Content in Technical Hemp

Optimal nutrition and fertilization of cannabis plants are important parameters in the plant cultivation process to ensure their optimal growth, achieve maximum yield and desired values of cannabinoid content [3]. In the field of technical cannabis nutrition is known that the nitrogen dose is in the range of 50 - 200 kg N/ha [1, 8]. It also follows from the literature that plant nutrition, or some of the nutrients, can affect the final content of cannabinoids in the plant, as well as its total yield. The aim of this work was to verify whether fertilization with mineral fertilizers (NPK) would lead to the influence of biomass yield and Delta 9-tetrahydrocannabinol (THC) content in the inflorescence of technical cannabis plants. For comparison, was chosen a variant where no fertilizers were applied.
