Abstract. In the agricultural production of the Republic of Adygea, according to long-term average data, the yield of sunflower seeds is about 1.0–1.2 t/ha, while it does not exceed 0.7–0.9 t/ha in individual farms. The purpose of the work was to determine the productivity and quality indicators of seeds of new promising sunflower hybrids in the conditions of the Republic of Adygea, depending on the elements of agrotechnology. The scientific novelty of the results obtained during the experiment is that for the first time, studies with new sunflower hybrids were conducted on the leached chernozems of the republic and some elements of their cultivation technology were improved. The research methods correspond to the field experience methodology by B. A. Dospekhov. Results. The article presents the results of experiments determining the effectiveness of the use of nitrogen-phosphorus fertilizers in agricultural technologies against the background of dump plowing to a depth of 25–27 cm and deep loosening of 35–40 cm. As a result of the research, it was found that the maximum yield level (average 3.0 t/ha) was achieved for all studied hybrids, namely, against the background of dump plowing of the soil to a depth of 25–27 cm. In the course of research, it was found that the oil content of hybrid seeds depended on fertilizers and the method of tillage. The Sprint hybrid has the greatest potential oil content, where its value is fixed at 49.4 % against the background of dump plowing, and 45.3 % against the background of deep loosening. On average, according to experience, in the variants of basic tillage, the oil content of seeds was at the level of 48.3 % (dump plowing) and 44.4 % (deep loosening).
