Productive potential of variety is always used as the most important characteristic, that is why investigation of productivity elements according to their influence on the productivity has been conducted for a long time. Fertilizers also are one of the effective and fast-acting factors of increasing winter wheat productivity. The purpose of researches was establishment of influence of variety properties and fertilizers on forming winter wheat productivity in production conditions of Poltava region. Materials for researches were three varieties of soft winter wheat of different geographical origin: Dykan’ka, Selyanka, Kryzhynka with the variants of experiment: without fertilizers (control); N30Р60K60; N60Р60K60. Level of forming winter wheat productivity was studied during 2012 – 2013 years. Variety Selyanka with the dose of fertilizers of N60Р60K60 has been selected according to the investigated characteristic. It is recommended for growing in production conditions winter wheat variety Selyanka with the purpose of obtaining high and stable yields.
