Hemp is gaining increasing interest due to its high yield potential and multiple uses. This study was conducted under field conditions at ARDS Secuieni to assess the influence of sowing time and fertilization on yield performance, physiological traits, and biochemical quality of an early monoecious hemp variety, using a bifactorial split-plot experimental design. The E1 × F1 combination enhanced vegetative biomass accumulation, resulting in the highest inflorescence biomass (5300 kg·ha⁻¹ fresh and 1600 kg·ha⁻¹ dry) and stem yield (4380 kg·ha⁻¹), whereas seed production reached its maximum under the E1 × F2 combination (3293 kg·ha⁻¹). The second sowing time (E2) was associated with the highest photosynthetic rate (14.5 μmol CO₂·m⁻²·s⁻¹) and the greatest amount of carbon stored in the soil (68.3 t·ha⁻¹), while F1 fertilization recorded the highest photosynthetic rate (15.5 μmol CO₂·m⁻²·s⁻¹). Moreover, the interaction between the second sowing time and F1 fertilization maximized vitamin C content (67.3 mg·100 g⁻¹) and soluble solids (12.3 °Brix). Overall, the results highlight the importance of appropriate sowing time and fertilization in improving productivity and quality in monoecious hemp.
