Determinants of Direct seeding rape yield

The yield of direct seeding rape is also composed of density, effective pods per plant, filled grains per pod and 1000-grain weight. Because the individual growth and development of direct seeding rape is poor, the productivity per plant is low, the number of branches and pods per plant are few, the key factors determining yield are mainly controlled by the main stem and the effective number of pods of primary branch, so in order to obtain high yield, density is a main determining factor. Direct seeding rape should increase the density to increase the number of main stem and primary branches to ensure the total number of pods per unit area and ensure the yield.
