S 483

S 483 is a medium-early sunflower hybrid intended for intensive cultivation using modern technologies such as SUMO® and sulfonylurea herbicides (tribenuron-methyl). The vegetative period is approximately 101–110 days, allowing the hybrid to successfully adapt to various climatic conditions. Plants reach a height of about 170 cm, and the head diameter is approximately 24 cm with a semi-convex shape and upward orientation. The hybrid is characterized by high yield stability with a potential of up to 57–58 c/ha and an actual yield within the range of 36–42 c/ha, confirming its effectiveness under various growing conditions. One of the key advantages of S 483 is its high resistance to stress factors and diseases. The hybrid demonstrates excellent drought tolerance thanks to a powerful root system, which is especially important in arid regions. It is also resistant to new races of the sunflower pest Striga, as well as to diseases such as black leg, peronosporosis, phomopsis, rust, downy mildew, and grey and white molds. The resistance level to these diseases is rated at 8–9 out of 10, ensuring reliable protection and minimizing crop losses. For optimal crop formation, it is recommended to adjust planting density based on soil moisture levels: with sufficient moisture — 55–65 thousand plants per hectare, with moderate moisture — 50–55 thousand, and with insufficient moisture — 45–50 thousand. Seeds are supplied in two fractions — standard and extra, with a 1000-seed weight ranging from 53 to 73 grams. The oil content in the seeds is 50–52%, making the hybrid attractive for the production of high-quality sunflower oil. Due to its characteristics, S 483 is a reliable choice for farmers seeking high and stable yields under various agro-climatic conditions.
