Field trials were conducted at the Lithuanian Institute of Agriculture in Dotnuva on a light loamy soddy-gleyic soil in 1993-1997. Spring oilseed rape cv. 'Star' was sown to investigate the effect of nitrogen fertilizer rates and timing on the variation of nitrogen, phosphorus and potassium content in plants. The investigation showed that with the increase of nitrogen rates the content of nitrogen and potassium in the plant during the vegetative growth period as well as in seed and straw increased or at least tended to increase
