Mustard "Rosava" is a variety of sarpetska mustard, known for its high drought resistance and ability to quickly develop a powerful root system. Seeds of this variety germinate at temperatures from +1 to +3 °C, and seedlings withstand frosts up to -4–5 °C, making it suitable for early spring sowing. Under optimal conditions, yield reaches 20–23 centners per hectare, while a sowing rate of 1.5 to 2.0 million seeds per hectare is recommended (corresponding to 5–8 kg/ha for sarpetska mustard). For maximum efficiency, the sowing should be preceded by soil treatment and application of fertilizers in the autumn period, as well as seed treatment with insecticides against the cabbage flea beetle.
