In the conditions of the Republic of Belarus there was determined the dependence of yielding capacity and quality of hops of common hop (Humulus lupulus) on terms of application of the main dose of nitrogenous fertilizers at plant nutrition on sod-podzolic sandy loam soils. For the receiving of maximal productivity of hop cones of Hallertauer Magnum variety (19.7-20.0 center/ha) and maximal yield of alpha-acids per one unit of arable area (2.16-2.32 center/ha) on sod-podzolic coherently sandy loam soil of the western region of the Republic it was recommended to apply the main dose of nitrogen at the beginning of formation of stem shoots (N35+110+35) or at the beginning of flowering (N35+35+110). But for the receiving of cones with the maximal content of alpha-acids (11.8%) and their maximal yield per the arable area unit (2.32 center/ha) it was recommended to apply the main dose of nitrogen at the beginning of formation of stem shoots.
