The increased interest in the introduction of non-traditional crops is justi-fied by the search for economically profitable sources of technical resources of non-wood origin, the introduction of which would create a raw material base for pulp production. One of these crops, which at low cost gives the maximum yield of biomass for a long period of time without adversely affecting the natu-ral balance, is a fast–growing perennial herbaceous plant, giant miscanthus. It is possible to grow it without prejudice to food crops and to preserve forests. It is quite possible to use the raw materials of the giant miscanthus for the production of cellulose. In order to introduce miscanthus into agricultural pro-duction, its productivity and chemical composition were studied during its in-troduction in the Middle Volga region. Therefore, in 2013, an experiment was laid on the light gray soil of the Penza State Agrarian University site. During the eleven years of its growth, the fourth and fifth years of life were the most productive, when the yield of the aboveground mass was 40.0-41.0 t/ha. In the period 2013-2023, 321.0 t/ha of miscanthus green mass was obtained, which corresponds to 114.0 t/ha of dry mass. In terms of cellulose, the content of which was 55.5%, its yield during the study period reached 63.0 t/ha, that is, an average of 5.7 t/ha annually with a single planting. With the traditional production of cellulose from wood, its yield is 40.0 tons per hectare of forest at the age of 70-100 years. The content of lignin in the parts of miscanthus is 20.9%, with a moisture content of 7.7%, pentazanes is 19.9%, ash is 2.63% and adipose fraction is 0.9%.
Keywords: giant miscanthus, introduction, yield, cellulose, lignin, pento-sans, ash content, fat fraction.
