Abstract: Under the conditions of field experiments, new rape (named 159GP10) was conducted which included different sowing dates (September 30th, October 10th, October 20th and October 30th in 2015) and nitrogen (N) fertilizer treatment ( 0, 90, 180, 240 and 360 kg/hm2), and the main agronomic characters and grain yield were analyzed. The result shows that: there exits a great difference in growth process of 159GP10 at all sowing dates, but they do not change after the initial flowering. Meanwhile, the rape growth process was also affected under the different N fertilizer treatment, which indicates that rape in N(0 )treatment would be maturity earlily and its was earlier than 360 kg/hm2 by 8 days. With the increasing of N fertilizer, the number of green leaves, maximum leaf length and leaf width were gradually increasing trend, but the plant root diameter under 180 kg/hm2 was the highest. With sowing date postponing and N fertilizer reduction, strains height, effective number of branches, main sequence length and pods of rape plant are decreased, especially, pods was reduced significantly (p<0.05). Under different sowing date treatment, yield of October 10th treatment was the highest(3315.84 kg/hm2), that shows October 10th> September 30th > October 20th > October 30th.Under different N fertilizer treatments, the yield of 180 kg /hm2 was the highest (3157.18 kg/hm2).
