Biomass yield and energy balance of Virginia fanpetals in different production technologies in north-eastern Poland

This study compares the biomass yield and energy efficiency of Virginia fanpetals grown in two production technologies (low- and high-input) during a long-term field experiment conducted in north-eastern Poland. The analyzed crop was characterized by higher above-ground biomass yield and superior performance in the high-input relative to the low-input technology (5.1 vs 4.4 Mg ha−1 y−1 DM). Biomass yield increased until the third year of the...
