In the conditions of the Republic of Belarus in 2009-2010 there was determined the dependence of yielding capacity and quality of hops of common hop (Humulus lupulus) of Hallertauer Magnum variety on terms of application of the main dose of phosphorous fertilizers at plant nutrition on sod-podzolic sandy loose loam soils. In course of the study there was showed the influence of phosphorous fertilizers on the correlation between hop cone weight and leaf weight and on the weight of 1square meter of leaf area. Also there was showed the influence of phosphorus on leaf weight formation and leaf area. Research results showed that for the maximal yielding capacity of hop cones of Hallertauer Magnum variety (19.9 center/ha), the maximal content of alpha-acids (11.8%) in hop cones, as well as the maximal yield of alpha-acids per the arable area unit (2.36 center/ha) on sod-podzolic loosely-sandy-loam soils of the western region it was recommended to apply N180P160K240 against the background of 30 tons/ha of organic fertilizers.
