Екологічна пластичність сучасних сортів ячменю ярого залежно від фонів живлення

Abstract

The outcomes of the three year researches (2009-2011) on the ecolog- ical trials with modern varieties of spring barley for genetic potential and stable yield realization in the Eastern part of the Forest-Steppe of Ukraine depending on nutritious background are shown. The variety of barley spring Vzirets turned out to be the most valuable by indices of the average yield in the years (2,38-3,82 t/ha), the least fluctuation in yield (1,37-1,93 t/ha) and the highest agronomic stability (As = 74,6-77,9 %) depending on the nutri- tious background
