R 504 S 11 is a winter rapeseed belonging to the Brassica family. It is a herbaceous plant with a powerful taproot system penetrating up to 3 meters deep, with the main mass of roots located at a depth of 25-40 cm. During the vegetation period, a rosette forms in autumn, and in spring, an upright branched stem develops, reaching a height of 150-180 cm with sessile leaves that wrap around the stem for one third or two thirds. The flowers are yellow, gathered in a loose raceme, with the number of flowers on the plant reaching 400-800. The fruit is a narrow pod 6-15 cm long, containing 35-40 seeds of dark brown or black color. The weight of 1000 seeds is 4.5-6 grams. The vegetation of winter rapeseed lasts about 295-300 days, including the spring-summer period lasting 73-110 days.
The hybrid R 504 S 11 has a high genetic yield potential and consistently shows good results under various growing conditions. It is suitable for late sowing, especially in regions with insufficient moisture, which allows including this crop in crop rotation even with limited moisture. The average yield of the hybrid is 34-44 centners per hectare, and the sowing rate is 450-600 thousand plants per hectare.
For successful cultivation of rapeseed R 504 S 11, the correct fertilization system is important, including seed preparation, main fertilization, fertilization at sowing, and top-dressing during the vegetation period. The plant requires certain norms of nitrogen, phosphorus, potassium, and other nutrients, which depend on the soil type and the supply of elements to the plants. The optimal level of soil acidity for rapeseed is pH 6.2-7.0. The sowing depth of seeds is 2-3 cm, and with precise sowing, the rate is 5 kg per hectare.
