Soybean is widely used as food. Genetic factors, as well as agrotechnical procedures, affect the yield and quality of soybeans. The subject of our research was the synchronization between soil N supply (from both mineralization and fertilization) and crop N demand. The aim of the research was to determine the effect of the cultivar and nitrogen application on the seed yield and mineral content in soybeans. Two non-GMO soybean cultivars (Amandine and Merlin) and four mineral nitrogen fertilizers ((A) N 0, control; (B) N 30:0, 30 kg N ha before sowing; (C) N 0:30, 30 kg N ha at BBCH 73-75; (D) N 30:30, 30 kg N ha before sowing and 30 kg N ha at BBCH 73-75) were tested. The highest soybean yield was obtained following nitrogen application at a rate of 60 kg ha. The genetic factor was found to significantly influence the content of some macronutrients (P, K, and Mg) and micronutrients (Cu, Mn, and Fe). In general, the Merlin cultivar had better macronutrient parameters except nitrogen, while Amandine had a higher content of Cu and Fe. Nitrogen fertilization decreased the content of P, K, and Zn in the soybeans but significantly increased the content of Ca, Mg, Cu, and Mn.
大豆被广泛用作食物。遗传因素和农业技术措施都会影响大豆的产量和质量。我们的研究主题是土壤氮供应（来自矿化和施肥）与作物氮需求之间的同步性。研究目的是确定品种和施氮量对大豆种子产量和矿物质含量的影响。我们测试了两个非转基因大豆品种（Amandine 和 Merlin）和四种矿物氮肥（(A) N 0，对照；(B) N 30:0，播种前施 30kg N/ha；(C) N 0:30，在 BBCH 73-75 时施 30kg N/ha；(D) N 30:30，播种前施 30kg N/ha 和在 BBCH 73-75 时施 30kg N/ha）。施氮量为 60kg/ha 时，大豆产量最高。遗传因素显著影响一些大量营养素（P、K 和 Mg）和微量元素（Cu、Mn 和 Fe）的含量。总体而言，除氮外，Merlin 品种的大量营养素参数更好，而 Amandine 品种的 Cu 和 Fe 含量更高。施氮会降低大豆中 P、K 和 Zn 的含量，但显著增加 Ca、Mg、Cu 和 Mn 的含量。
