加拿大油菜（Brassica rapa或Brassica napus）产量约为620万吨（2003年），其中98%以上种植在三个草原省。约有460万公顷土地种植油菜，平均产量为1.35吨/公顷。沿着油菜籽中产量和N含量的增加，还报道了使用N肥料时油含量的降低（Lickfett等人，1999;杰克逊，2000;布伦南等人，2000）。很少有研究调查的表现，油菜生长在土壤中接受长期牲畜粪便。本文的目的是研究长期大量施用牛粪对油菜种子油分和氮含量之间关系的影响。
Canola (Brassica rapa or Brassica napus) production in Canada is about 6.2 million t (2003), with over 98% grown in the three Prairie Provinces. About 4.6 million ha of land are under canola production, with average yield of 1.35 t haą1. Along with increases in yield and N content in canola seed, decreases in oil content have also been reported with the use of N fertilizer (Lickfett et al., 1999; Jackson, 2000; Brennan et al., 2000). Few studies have investigated the performance of canola grown in soil receiving long-term livestock manure. The purpose of this paper is to examine the effect of longterm heavy cattle manure application on the relationships between oil and nitrogen content of canola seed.
