Animal husbandry is severely restricted by insufficient grass production in northern pastoral areas in China. To improve forage rapeseed (Brassica napus L.) for large-scale planting in Heilongjiang Province, yields of several rapeseed varieties were analyzed on nutrient accumulation and fertilization effect under different cultivation modes by multi-point field tests. Results showed that yield advantages of Jinyou 158, 15-P15 and 12-P38 were rel? atively high. High yield was obtained under conditions of 15 kg/hm2 weight of sowing seeds, 150 kg/hm2 diammoni? um phosphate and forage rapeseed planted early on April 22. The biomass was relatively high in flowering time and better silage would be made by mixing with corn straw. This research was expected to provide reference for multifunctional utilization of forage rapeseed in the precocious zone of northern China.

Key words: forage rapeseed, yield, fertilization effect, precocious zone of northern China
