The use of physical factors for preplant stimulation
of seeds increases vigor, germination and improves
the yield of agricultural products. One of the effective
ways to improve seed grain quality is to impact
on the seeds using physical factors, in particular, an
alternating electromagnetic field of industrial frequency
of 50 Hz (EMF of IF of 50 Hz). We studied
the impact of EMF of IF of 50 Hz on the energy
germination of mid-ripening spring barley seeds of
promising varieties Vakula, Vikont, Ratnik. Carrying
out the experimental studies we used a laboratory
setup with annular pole points of rectangular
cross section. Our disperse analysis resulted in data
on germinative energy of seeds of spring barley
varieties Vakula, Vikont, Ratnik, which showed that
while treating seeds of spring barley by an alternating
electromagnetic field of industrial frequency of
50Hz, we obtained the best values of germinative
energy of seeds of Variety Vikont with a mode of
processing being equal to W = 16%, T = 2 c, L =
0,03 m
The results of the research of the stationary experiment at "Kuban" educational farm of Kuban State Agricultural University have been submitted. We have traced the direction of change of humus status of black leached soil
The article identifies the value of livestock in the economy of the Bryansk region; we have also given the spatial-temporal analysis state of the industry and identified the key trends in its development over the past 25 years. This work considers the geography of industries and production of major livestock products
The article presents the results of the evaluation of the spatial structure and condition of trees and shrubs in different types of park stands located in the park called “Yamka” in Petrozavodsk. Features of planning and spatial distribution of trees and shrubs have been identified. The species and number of plants in good, satisfactory and unsatisfactory states were determined. The conducted analysis of species distribution and the number of trees and shrubs in each category of state allows suggesting the activities for reconstruction of park stands
Duration of vegetation period is one of the main
adaptive traits for any crop or variety. Reasonability
of cultivation of a variety in a particular soil and
climate zone is determined by the duration of the
vegetative period. One of the aims of breeding is
the creation of the varieties with the main vegetative
phases lasting at more favorable climatic conditions.
The most accurate way to determine maturity
group of a variety is by estimation of starting
of heading phase, which can be defined with the
greatest precision. The article covers the analysis of
the duration of the vegetative period of the lines
and varieties of winter barley of local and foreign
selection in the central zone of Krasnodar region.
All the varieties were divided into three maturity
groups. The vegetative periods of the varieties were
studied during four years. The most favorable and
adverse conditions for yield formation were determined.
The interactions between the productivity of
the varieties depending on maturity group were
identified. The varieties of the early maturity group
which are more productive than the check were
selected, which is most valuable for the breeding of
the crop. The best varieties with the high and stable
yield and the positive traits are regularly involved
in the breeding programs with the porpoise of making
new varieties of the winter barley
In this article, the analysis of thoroughbred sows of breed of Landrace and hybrid sows F1 in a combination (Yorkshire × Lanrace) on reproductive qualities and an index of commodity weight of a nest (ICWN-6) is presented. The economic benefit forecast is resulted at introduction system of hybridization with the use of imported breeds
The article presents the analysis of climatic data concerning Michurinsk district of Tambov region, which is necessary for modeling of stressors, on the stage of their maximum values, which will help to increase the precision of selection procedure in fruit crop forms. On the base of the investigation, differences in initial fruit crop forms by their adaptivity and productivity under stressor effect on the level of their maximum values were revealed
The article gives the analysis of installations using physical factors for seeds presowing treatment, particularly an electromagnetic field. The author has also cited an example of the registered installations for seeds presowing treatment by means of an electromagnetic field
In the article we show the investigations of aromatic wine produced from grapes of Sauvignon blanc grown in AF South in Temryuk District. As a result, the article estimates obtained good organoleptic characteristics of the taste, within 7.3-7.9 points, which is higher than the passing score. It was found that the greatest negative impact on the formation of mutual organoleptic properties have such flavors as metilatse-tal and the amount of volatile acids
