The paper presents the influence of the soil tillage system on the degree of weeding and corn yield in the period 2018- 2023. The research was carried out at the Agricultural Research and Development Station Turda, unit located in the hill area of the Transylvanian Plain. Compared to 2018 there was an increase a number of weed species, in the conventional system (CS) from 16 to 20 species/m 2 and in the variant with direct sowing (NT) from 19 to 43 species/m 2. In the Turda area, dicotyledonous weed species predominated. The yield results obtained in the six years showed that on the type of soil with a high clay content (41%), the corn does not lend itself to cultivation in the NT variant (directly sown), requiring soil mobilization, yield data confirming this fact (CS 8073 kg/ha; NT 5012 kg/ha).References
