Abstract

The effects of different sowing date,density and nitrogen level on the yield of rapeseed were studied in the field test conducted in Jiangdu district of Yangzhou city,Jiangsu province to establish high yield direct-seeding rapeseed planting technology in no-tillage paddy field with rice straws.The test result showed the planting conditions of sowing around Sept.30th,with seedling density of 450 000～750 000 ind./ hm2(mature plant density of 375 000～570 000 ind./ hm2) and nitrogen dose of 270 kg / hm2,was helpful for obtaining high yield of the direct-seeding rapeseed in no-tillage paddy field.
