In course of the research there was studied the influence of doses and terms of application of nitrogen fertilizers on yield forming of winter triticale (Triticosecale) varieties. The research was realized in the conditions of the southwestern region of the Republic of Belarus (Brest region) in 2008-2010 on sod-podzolic sandy loam soil. The agrochemical indicators of arable horizon were: pHKCl – 5.96, content of P2O5 – 214 mg/kg, K2O – 286 mg/kg of soil. Phosphorous fertilizers and potassium fertilizers were applied in autumn under plowing. Fungicidal treatment of winter triticale crops was carried out in the flag leaf stage with preparation Amistar Extra. As a result of realized research it was revealed that in the conditions of southwestern region of Belarus on a background of mineral fertilizers N70P90K120 the highest productivity was obtained at the national variety Zhyten and the foreign variety Voltario, and the national variety Antos conceded them on 4.8-5.5 c/ha. On a background of mineral fertilizers N130P90K120 and N160P90K120 varieties Antos, Zhyten and Voltario formed practically identical productivity (58.0-62.7 c/ha) whereas variety Mikhas conceded to them on 3.2-4.8 c/ha.
