Biological and agrotechnical progress in field crop production requires new solutions in the construction and operation of agricultural machines. Strip tillage with simultaneous fertiliser application and seed sowing requires specialised machines with working elements adapted to working conditions. As a result of research and development work, the soil loosening tines, fertiliser applicators and seeding coulters of a hybrid machine operating in a single-pass technology were developed, with improved material and construction. The effects of their use in winter and spring plant agrotechnology were assessed in field experiments. The growth, yield and quality of winter wheat and rapeseed crops, as well as spring barley, peas and maize were determined. The yields of these plants cultivated using a machine equipped with innovative working elements were 2.7–6.9% higher (depending on species) than the yields from plots cultivated using a standard machine. The difference in yields was mainly due to the greater field emergence capacity of plants. The density of plants before harvest and ears of cereals was also higher, as was the mass of grain per plant in maize. Pea seeds grown with the innovative machine contained 0.4 percentage points (pp) more protein, and rapeseed seeds contained 0.4 pp more fat than seeds grown with the machine without any structural changes.
