The aim of the research based on the results of a field experiment was comparison of the effect of two nitrogen fertilizers: the traditional ammonium nitrate and SULFAMMO 30 N PRO. The analysis comprises the effect of the aforementioned fertilizers on the chemical composition of triticale grain (xTriticosecale Wittm. ex A. Camus), cv. Nagano. The field experiment was carried out in the years 2013-2014 at the Experimental Agricultural Station in Lipnik (53º42′ N; 14º97′ S). The modern fertilizer SULFAMMO 30 N PRO contains 30% N (in the most effective forms: ammonium and amide), 15% SO3 3% MgO. There were no significant differences between the analyzed fertilizers (ammonium nitrate and SULFAMMO 30 N PRO) in terms of the content of the analysed macro- and microelements: nitrogen, phosphorus, potassium, calcium, magnesium, iron, zinc and copper in the grain of spring triticale, cv. Nagano. Application of nitrogen fertilization at the highest dose of 120 kg N·ha^-1 resulted in a significant increase in nitrogen and iron content in the spring triticale grain. On the whole, the results of the experiment indicate high stability in terms of macro- and microelements content in spring triticale grain of Nagano cultivar.
