Specifications
These premium Brassica campestris rape seeds go through strict cleaning and screening to remove shrunken, cracked and underdeveloped seeds to maintain consistent germination. This upright annual brassica crop grows thin branching stems and soft green lobed basal leaves. Clusters of bright four-petaled yellow flowers bloom on the upper stems in spring. After flowering, long slender seed pods develop and hold numerous small round dark seeds. It features rapid early growth and uniform maturity under suitable field conditions.
Product Advantages
Brassica campestris adapts well to cool climates and poor soil, making it an outstanding cool season oilseed crop. Its abundant yellow blooms attract bees and pollinators widely for honey production. It can be used as green manure to improve soil fertility, or harvested as fresh animal forage. Pair it with forage crop seeds to build a diversified farm planting system.
Planting Method
Sow seeds in early spring or late autumn, optimal soil temperature 6–20°C. Direct sow seeds 0.5–1cm deep into prepared soil, keep 20–30cm spacing between rows. Keep soil slightly moist before germination, seedlings emerge within 5–10 days. Choose sunny location with well-drained loamy soil. Thin overcrowded seedlings to leave proper space. Apply boron fertilizer before blooming to promote pod setting. Harvest seed pods when they turn yellow-brown and before pods split open.
Suitable Climate
Brassica campestris prefers cool temperate and subtropical climates. It tolerates light frost in seedling stage, while mature plants cannot survive heavy freezing. It grows best at 10–22°C. High temperature above 28°C will accelerate bolting and shorten the growth cycle. In hot tropical zones, it can only be planted in cool winter seasons.
Applications
Ideal for commercial oilseed field cultivation, bee pasture planting, farm green manure, livestock forage and wildflower landscape. The flowers serve as major nectar source for beekeeping; seeds can be pressed for edible oil.
FAQ
Q: What is Brassica campestris mainly used for? A: It is primarily planted for seed oil extraction. It can also act as bee forage, green manure to enrich soil organic matter or fresh feed for livestock.
Q: When to harvest rape seeds? A: Harvest when most seed pods turn yellowish brown. Do not delay too long, as over-ripe pods will split and lose seeds.
Q: Does rape need rich fertilizer? A: It needs moderate nitrogen fertilizer at seedling stage. Boron supplement is critical in blooming period to reduce empty pods.
Q: What diseases commonly affect Brassica campestris? A: Downy mildew and sclerotinia rot are typical diseases. Rotate crops and keep good field ventilation to lower disease risks.
Q: Can Brassica campestris grow in pots? A: It can be sown in large containers, but it develops tall stems and heavy root systems, so field planting gets much better yield.
