The mobilization and acclimatization of new herbaceous plant species, plant breeding and development of technological elements in order to obtain the maximum biomass yield for further processing into various types of products, are important research activities. We investigated some biological features and the biochemical composition of the biomass of a non traditional crop, giant knotweed – Polygonum sachalinense cv. “Gigant”, and evaluated the green mass nutritional value for animals and biomethane productivity for renewable energy. It has been determined that, in the 3rd year, the cv. “Gigant” was characterised by high growth and development rates; the green mass yield reached 12.3 kg/m2; the calculated fodder productivity – 22 t/ha nutritive units and 3700 kg/ha digestible protein; it can be a good source of essential amino acids in the livestock feed, exceeding substantially traditional crops, such as alfalfa – Medicago sativa. The biochemical methane production potential 249-253 L/kg VS.
