Abstract: Hemp (Cannabis sativa L.), as a valuable source of biomass, has been utilized for textile purposes, the production of environmentally friendly polymeric materials, modern composites, and paper. Moreover, hemp can be used for biofuel production. Therefore, optimal conditions for the cultivation of hemp varieties are essential. The aim of this study was to optimize agronomic practices—sowing date, row spacing, and mineral fertilization —to maximize straw and seed yield of the monoecious hemp cultivar ‘Henola’ under temperate climate conditions. Field experiments were conducted over three growing seasons using a randomized block design, testing five fertilization treatments, three sowing dates, and three row spacings. Statistical analysis revealed that high nitrogen doses (PK + 120 N) significantly increased both straw and seed yields. The optimal sowing period was from late April to early May. Narrower row spacings (0.2 m and 0.35 m) favored higher seed yields, while row spacing had no significant effect on straw biomass. These findings support the development of evidence-based recommendations for maximizing hemp yield depending on end-use objectives.
