Variable-rate nitrogen (VR-N) application enables farmers to optimize nitrogen (N) rates site-specifically within a field, enhancing economic and environmental efficiency. This study applied VR-N technology to durum wheat in two commercial fields (3–4 ha each) located in different agro-climatic zones of Thessaly, central Greece. Using a well-established algorithm, VR-N doses were calculated based on near real-time data acquired via unmanned aerial vehicle (UAV) imagery, tailored to the plants actual needs. Results showed that VR-N reduced N fertilizer usage by up to 50% compared to the uniform rate nitrogen (UR-N) application traditionally employed by producers. Importantly, this reduction did not significantly impact wheat yields or grain quality. Additionally, soil analysis revealed lower residual nitrate levels in VR-N zones compared to UR-N zones, indicating a reduced risk of groundwater N pollution.
