(processing of the results obtained) methods of research. The use of mixed feeds in
feeding chicken broilers which contained glycinate of Manganese, Zinc, Iron and
Copper making 75 % of the needs, contributes to increasing their body weight by 2.5
% and increasing the growth rate by 2.4 %. Feed costs per 1 kg of chicken broilers’
growth were 1.5 % lower than the young bird index of the control group.
The sixth section “OPTIMIZATION OF IRRIGATION NORMS AND
OPERATIVE MANAGEMENT OF IRRIGATION WITH PAID WATER USE”. The
article presents the method of calculation and optimization of irrigation norms, which
is based on simulation modeling of options and graphical optimization in conditions of
different prices for water during the years of different water supply. Estimates of
additional net profit from irrigation for the main crops are carried out. The method of
operative management of irrigation with the use of water-saving irrigation regimes and
the use of a multi-layer model of moisture transfer based on theoretical principles of
the thermodynamic approach is proposed. The method solves the problems of soil
moisture control during irrigation with high accuracy on the basis of the adaptation of
the model parameters to the specific conditions of the field. The reduction coefficient
of the two-layer and the parameters of the multilayer models of moisture transfer for
operational watering planning are checked and identified. A comparison of the
calculated and predicted values of soil moisture, which confirms the reliability and high
efficiency of the multilayer model of moisture transfer for operational control of
irrigation, is carried out.
The seventh section “GENETIC FUND OF THE GENUS VIGNA SAVI AND
IDENTIFICATION
OF
DONOR
SOURCES
BY
MORPHOLOGICAL
CHARACTERISTICS AND DURATION OF THE GROWING SEASON”. The
complex assesment of the genetic fund of the genus Vigna Savi has been investigated
and conducted on interspecific, intraspecific and intrapopulation levels. It has been
determined that varieties of vigna in terms of morphological variability are more
homogeneous than populations. The collectible specimens were marked by an average
level of variation in the duration of the growing season and individual phases of the
development (0.5-20.7% depending on the type of vigna and genotype). The
established asymmetry and excessive variability of the economic characteristics in the
populations of the studied species of vigna indicate the peculiarities of the response of
the corresponding genotypes to the action of the environmental factors and can serve
as a criterion for the adaptability of the species as a whole and individual collection
patterns in particular. The significant level of variability of the economic characteristics
in the studied species and individual samples of vigna indicates a significant genetic
heterogeneity of the study collection and the plasticity of the genotypes to the action
of environmental factors. With the use of the Shannon variety index and the Piel
equation index, a high level of total phenotypic variability of the vigna collection is
