The aim of the research was to assess the impact of planting dates and patterns and cultivation methods on the formation of individual productivity, raw yield and dry biomass and energy yield of giant miscanthus (Miscanthus giganteus) under field conditions in the forest-steppe zone of right-bank Ukraine. The article presents the results of three years of research. The field experiment was conducted using a three-factor experimental design: planting dates (second decade of October and first decade of May), cultivation methods (with and without ridge formation) and planting patterns 70x55 (25 thousand plants/ha and 70x70 (20.0 thousand plants/ha) with sequential placement of variants in the experiment with fourfold repetition. The highest yield of raw biomass (16.5 t ha⁻¹), dry biomass yield (13.5 t ha⁻¹) and energy yield (238.1 GJ ha⁻¹) were obtained when the rhizomes were planted in October without ridge formation at a density of 25,000 plants ha⁻¹. Plant survival and shoot density were significantly dependent on planting date and cultivation method. The dry biomass yield showed a strong positive correlation with the number of shoots per rhizome (r = 0.951, R² = 0.9046) and shoot height (r = 0.985, R² = 0.9693) according to Pearson's correlation analysis at a 0.01% significance level. These results demonstrate that optimising planting dates and density is crucial for maximising biomass productivity and energy yield of miscanthus in the conditions of the right-bank forest-steppe, thanks to improved early establishment and vegetative development in autumn planting conditions.
