SRP 43309 KL is a winter rape variety distinguished by high yield and resistance to adverse conditions. In terms of yield, it surpasses many hybrids from well-known European breeding brands, achieving an average yield of 5.5 tons per hectare. Rape is a late-maturing variety with excellent shattering resistance, ensuring crop preservation. It is recommended to sow it early at a seeding rate of 650,000-700,000 viable seeds per hectare, corresponding to a mass of 10-20 kg/ha. The plants reach a height of about 138 cm, while the mass of 1000 seeds is 4.9-5.2 grams. SRP 43309 KL exhibits high disease resistance, particularly to various types of rots, significantly reducing the risk of crop losses. The oil content in the seeds reaches 46.7%, while the erucic acid content is minimal at just 0.09%, making the oil high-quality and in demand for production. The variety is suitable for cultivation in various agro-climatic zones, including the Polesie, Forest-Steppe, and Steppe, and adapts well to different soil types, such as chernozems and loams. SRP 43309 KL can be grown using classic technologies or the Clearfield system, allowing for effective weed control and increased yield. Winter rape of this variety is widely used in agriculture to produce high-quality oil and can also be used as a green manure and fodder crop. Optimal sowing times and proper care ensure the maximum productivity potential, which can reach 60 centners per hectare.
