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.

How to thin and set the final stand of directly sown rapeseed
Methods for thinning and setting the final stand of directly sown rapeseed ⟦3 (Agricultural Wealth Network) Directly sown rapeseed is sown at a high rate and a relatively high density. If it is not thinned and set to its final stand in time, the excessive density will cause the seedlings to crowd each other and produce thin, weak, spindly seedlings. Timely thinning and setting the final stand at the right time are very important. Generally, one thinning should be done right after the seedlings emerge, and a second thinning at the 2-leaf stage. The final stand is best set in time after 4 true leaves. At the same time, inspecting the seedlings and filling in gaps should be done promptly.
