In the conditions of the Republic of Belarus there were determined the optimal doses and terms of nitrogenous (carbomide-ammonium mixture (UAN)) fertilizer application as well as the influence of plant growth regulator Moddus, emulsion concentrate (Switzerland production) on yielding capacity and grain quality of winter rye (Secale cereale) grown on sod-podzolic light loamy soil. On the basis of laboratory and field experiments it was concluded that over the three years of studied the maximal yielding capacity of winter rye was obtained after application of N30P60K90 + N30 + N20UAN. Split dressing with nitrogenous fertilizers against the background of N30P60K90 in three times (N20 after renewal of vegetation + N20UAN at the phase of stem elongation + N10UAN at the phase of ear emergence) did not promote the increasing of grain yield but increased the protein content on 1.3%, and yiel;d – on 1.3 c/ha. Application of Moddus against the background of N30P60K90 + N50 made it possible to increase yielding capacity of winter rye in average over three years on 1.4 c/ha but it did not render substantial influence on quality of rye grain.
