What factors determine the yield of direct-seeded rapeseed?

Determining factors of direct-seeded rapeseed yield ⟦3 (Agricultural Wealth Network) The yield of direct-seeded rapeseed is likewise composed of density, the number of effective siliques per plant, the number of filled seeds per silique and 1000-seed weight. Because direct-seeded rapeseed grows and develops poorly as an individual, with low per-plant productivity, few branches and few siliques per plant, the key factors determining yield are mainly controlled by the number of effective siliques on the main stem and primary branches, so to obtain high yield, density is a major determining factor. Direct-seeded rapeseed must increase density to increase the number of main stems and primary branches so as to ensure the total number of siliques per unit area and ensure yield.
