The sunflower variety 'Active' is a mid-season hybrid developed for effective cultivation in various regions, including the Lower Volga and East Kazakhstan. The vegetative period lasts about 112 days; the plant reaches medium height and does not branch. The leaves have a green color with moderate blistering, and ray florets are yellow. The mass of 1000 seeds ranges from 52.3 to 77.4 grams, indicating good seed size. Marginal stripes on the seeds are weak, which is characteristic of this variety. The variety is distinguished by high yield, averaging 20.4-23.8 centners per hectare, with maximum figures reaching up to 45.2 centners. Oil content in the seeds ranges from 43.0% to 46.5%, ensuring high oil output — up to 1106.7 kg per hectare. These characteristics make 'Active' attractive for oilseed production and processing. Additionally, the variety demonstrates moderate resistance to white mold and paspaline but is susceptible to downy mildew, which requires attention when selecting plant protection means. To improve cultivation efficiency and nutrient absorption, the use of complex chelate fertilizers such as Titon Bor Active is recommended. This preparation contains boron, manganese, cobalt, and molybdenum, which contribute to improved photosynthesis and enhanced nitrogen fertilizer efficiency. The fertilizer application rate is 1-3 liters per hectare, helping to increase yield and product quality. Thus, the 'Active' variety is a reliable choice for farmers seeking high-quality and high-yielding sunflower.
