Soybean is a plant with multiple uses both for food and feed purposes and in industry. This is due to the chemical composition, the richness in lipids and proteins, but also from an agronomic point of view, for nitrogen natural fixation and improving soil fertility. This paper presents the results obtained in 2023 and 2024 in a soybean crop on productivity elements and seed production, under fertilization conditions with different nitrogen rates (N0, N60, N90, N120) and under conventional tillage and minimum tillage conditions (5 variants). The results are presented from the point of view of the singular and combined effect on both the influence of soil tillage and nitrogen doses on production components, productivity, and proteins and lipids contents. For 2023, productions under the influence of deep tillage were noted, with productions over 4900 kg/ha and doses of N120 nitrogen. For 2024, under conditions of a dry year and high average temperature over 24oC during the summer, minimum tillage works were highlighted, respectively Gruber 15 cm and Disc 15 cm, with productions of 1954-2645 kg/ha. The high lipids and protein content was confirmed regardless of the soil tillage method, ranging between 17-20%, and as the nitrogen dose increased, the lipid and protein content also increased, oscillated between 35.23 (N0) – 37.95 (N120).
