Sunflower is a crop that forms a large vegetative mass, requiring a significant amount of moisture during the growing season. Therefore, it is very important to select optimal predecessors that have a short growing season so that plants do not need moisture for the entire period of growth and development. This especially requires compliance with the correct selection of the predecessor in case of insufficient moisture, when there is a moisture deficit and the amount of precipitation is not enough to provide plants with water. The formation of the photosynthetic apparatus, productivity elements, the size and quality of the sunflower seed harvest, according to the results of the research, was largely determined by the combination of predecessors of the crop rotation link, which includes sunflower. The sunflower hybrids studied demonstrated sensitivity to the physical and chemical properties of the soil that were formed after different predecessors. The most favorable link for growing the crop was the link: peas → winter wheat → sunflower, after which, when observing the recommended agricultural techniques, the formation of a yield of 2.7 t/ha was ensured with high technological indicators of seed quality. The results of the study showed that the Vsesvit hybrid confidently led among other samples in all aspects of its predecessors, both in terms of yield and seed quality characteristics
