ECONOMICAL AND BIOENERGETICAL EFFICIENCY OF WINTER BARLEY SORTS ON VARIOUS IRATION MINERAL NUTRITION
The results of the economical and bioenergetics effi-ciency estimation of using fertilizers of various winter barley sorts in the conditions of the South part of Ros-tov region are given and optimal variants of their usage are determined
Due to the wide spread of winter barley varieties with
different Phytopathologic characteristics, a serious
threat to the crop is dwarf rust caused by a pathogenic
fungi of the Puccinia. The article presents the results of
phytosanitary studies conducted in different agroclimatic
zones of the North Caucasus region for the
period from 2013 to 2015. Electronic maps of levels of
development and distribution of dwarf rust are based on
phytosanitary inspection. On the experimental field
called «Kuban» as well as rust nursery of VNIIBZR we
have performed an immunological evaluation of the
sustainability of winter barley accessions to the
pathogen of the dwarf rust on natural and artificial
infectious backgrounds in the period from 2013 to
2015. The article reflects the objective characteristics of
varieties and lines of winter barley with a relative
stability to the North Caucasian population Puccinia
hordei. The most promising varieties and lines of winter
barley of the KubGAU breeding were selected during
operation. These varieties and lines are highly resistant
to rust and dwarf, they also have other valuable
features. The article presents information on the best
yield varieties and lines of winter barley as well as on
gross yield and sowing area
