In the conditions of the Republic of Belarus there were presented research results of revealing of the reaction of winter triticale (Triticosecale) varieties to doses and terms of nitrogen fertilizer application on sandy-loam soils. The efficiency of fractional (in three stages) application of nitrogen fertilizers is shown. It has been established that in the conditions of southwestern region of Belarus the variety Antos was distinguished by the highest responsiveness to the increase of nitrogen doses. In the conditions of sod-poddzolic sandy loam soil against the background of mineral fertilizers in dose of N70P90K120 the most yielding varieties at high nitrogen nutrition were the national varieties Antos and Zhiten, and the foreign variety Voltario. Varieties Antos, Zhyten and Voltario formed practically identical productivity (58.0-62.7 c/hectare) on a background of mineral fertilizers N130P90K120 and N160P90K120. At the same time, yielding capacity of Mikhas was 3.2-4.8 centner/ha lower.
