Abstract: Strip tillage combines the positive aspects of no tillage and full-tillage technologies. The main objective of this work was to determine the influence of the technological parameters of strip tillage machines on agronomical aspects of faba beans (Vicia faba L.) cultivation, on energy consumption and CO2 emissions. Tests of strip tillage machine’s technological parameters was carried out in 2013–2014 at the Experimental Station of Aleksandras Stulginskis University (ASU), and experimental field research in 2016–2018 at the farmer’s farm, situated in Kaunas District. Tests in ASU was carried out by changing the row cleaner disc rake angle from 10.0o to 22.5o, the working depth from 0 to 200 mm, and the working speed from 1.4 to 3.1 m s-1. The results indicate that increasing the working depth from 0 to 200 mm increases the hourly tractor fuel consumption from 10.3 to 24.3% depending on the working speed. An analysis of the experiments indicates that the lowest fuel consumption and CO2 emissions per hectare were achieved at a working speed of 2.5 m s-1. CO2 emissions from tractors increased approximately 20% on average with a working depth increase from 0 up to 200 mm. Application of strip tillage technology at the farmer’s farm resulted an average faba beans yield of 4.4 t ha-1 or 0.2 t ha-1 higher than that of conventional tillage. A comparison of studies investigating different soil tillage technologies demonstrates that strip tillage is environmentally friendly. The assessment of the results showed that the technology of strip tillage uses up to 2 times less fuel, and CO2 emission are 13–20% lower than in conventional tillage
