Productivity of soybean and the possibility of using it as energy

Abstract

Harvest residues of sunflower, maize, oilseed rape and soybeans make up more than 50% of the total biomass yield and can also be used to obtain bioenergy. As a source of bioenergy, preference is given to harvesting residues that contain more cellulose and oil, such as soybean straw. Soybean breeding aims to create varieties with higher biomass and increased oil yield per hectare, as well as to create varieties that would be more suitable for industrial processing for the production of technical oils. In this study, the productive parameters of soybeans were investigated in two years, 2021 and 2022. The average yields of soybeans varied from 2.8 t ha-1 (2022) to 2.9 t ha-1 (2022). The total soybean biomass yield was 4.8 t ha-1, while the biogas yield was 384.5 m3 ha-1. The year had a significant impact on soybean production. The more favourable year for production was 2021, with significantly higher yields of grain, biomass and biogas, compared to 2022.
