Abstract

N fertilization has a considerable effect on the quantity and quality of canola (Brassica napus L. subsp. napus) yield. The N supply of crop, which is in relationship with the uptake of N and other elements, is determined by ecological factors (soil and weather conditions) and fertilization. The aim of present work was to investigate the influence of N fertilization on the element content of young canola grown on calcareous chernozem soil in 2003 autumn. There was a significant increase in the nitrogen content of plant samples collected in early October from N fertilized plots as compared to the control, while no changes occurred in the content of other elements. On the second sampling, in November notable changes could be observed in the shoot element content. As a response to N fertilization not only the N content, but P, K, Mg, Cu and Sr contents of young canola were higher and the Mo content lower as compared to control plants. The higher N supply level significantly increased the ratio of nitrogen to other elements (namely P, S, Ca and Mg), which indicates a lower rate of increase in the content of later elements. In addition to N fertilizer responses, changes in element contents were also due to the autumn growth of shoot mass. The K, S, Ca, Mg and Sr contents of samples taken on the second sampling date were lower in all treatments, while only control plants had lower N, P and Cu contents. The gained results underline the decisive role of N fertilization in the adequate nutrient supply of young canola.
