The article shows the parameters of growth of main tree species depending on planting density, placement of plants, location in the profile of plantations, the effectiveness of plantations
The article reviews four variants of laying nurseries of
primary branches of seed production of long-grained
rice varieties of the Kuban breeding taking into
account their biological features, plots area ranges
from 0,7 m2
to 1,1 m2
, seeding rate for one family –
from 100 pcs./m 2 to 170 pcs./m2 . We have studied
traits of long-grained rice varieties of the Kuban
breeding - Ivushka, Avstral, Kurazh, affecting the
yield and quality of seeds: yield, multiplication factor
and fractional composition of seeds depending on
laying multiplication nursery of first year progeny.
The differences between varieties by the type of
tillering, vigor, germination of seeds depending on
planting system are shown. Optimal way for laying
seed nurseries is found: for long-grained varieties with
medium tillering (Kurazh type) – row length – 3,3 m
and seeding rate – 120 caryopses/m2
; for those with
intensive tillering (Ivushka type) – row length – 3,8 m
and seeding rate - 120 caryopses/m2
. This will allow
using mechanical method of sowing using selective
cassette seeding-machine in the primary seed
production, reducing cost of seed production and
increasing efficiency of labor, increasing volume of
seed production of long-grained rice varieties in short
terms and accelerating their implementation in the
Kuban region for import substitution
The changing dynamics of nutrients in soil, doses of mineral fertilizers, efficiency, a mode of onion irrigation on irrigated soils of Rostov region are resulted in the article
The features of seeding and vegetative reproduction of
Hibiscus Syrian (Hibiscus syriacus L.) in the South
regions of Russia are accounted in the article. It is
shown that the not sorted Hibiscuses reproduce better
by seeds. Sowing is made before winter (November).
The young growth appears on April-May of next year.
The seedlings of first-year are wintering badly in the
open soil; therefore, it is better to keep them in the
basements in sand. When one-year seedlings are
planting next spring we receive the standard seedling
in the autumn this year. Planting material of high
quality of Hibiscus Syrian was grown by means of
inoculation and by the grafting method. It is
recommended to execute an inoculation in the first tenday
period of September. It is possible to execute the
reproduction by means of inoculation in case of deficit
of shoots of high quality plants and for the rapid fixing
of sort. It is preferable to reproduce a Hibiscus Syrian
by wood shoots in the frames or by green shoots in the
unheated greenhouses in an autumn-winter period. The
best results in the carried out research were got at
planting shoots for further growth in the containers at
the greenhouses with creating of shadow in a summer
period. The high speed of shoots growth in the
containers of cv. Duc de Brabant, cv. Woodbrige and
cv. Russian Violet varieties are observed. The
vegetative mass of shoots of cv. Speciosus,
cv.Carneus Plenus and cv. Red Heart varieties
increases more slowly. A conclusion follows, that the
studied crop must take the deserving place in the
assortment of decorative bushes of plant nursery farms
The technology production of microbiology preparation for protecting of plants from ill and insects was presented in this article. There are measures for improving the nutrient medium for growth of microorganisms
There was given the review of the results of the study
in the arid zone of Central Ciscaucasia, the influence
of planting terms and presowing seed treatment by the
drug called "TMTD-plus", containing the growth
stimulator Krezatsin in its composition, on the
development of corn hybrids of different maturity
groups of the selection of Krasnodar Research Institute
of Agriculture named after P.P. Lukyanenko (Ross
199, Ross 299, Krasnodar 382 and Krasnodar 410) and
the All-Russian Research Institute of Corn (Mashuk
170, Newton, RIC 345 and Eric), as well as middlematurity
population Rossiyskaya 1. The studies were
conducted in accordance with the thematic plan of
scientific researches of the chair of crop and forage
production of the Stavropol State Agrarian University.
The soil surface was presented as southern black earth.
The technology of growing of maize on the
experimental plot corresponds to the standard one for
the present area and cultivar. The predecessor is winter
wheat. Sowing was performed in three terms. The first
(early) sowing term was carried out at t = + 7 ... +8 °
C. The second (recommended) - when t = + 10 ... + 12
° C. The third (later) sowing time was carried out at t =
+15 ° C. The plant density: early-maturing hybrids –
70 thousand pieces/ha, is mid-maturing ones – 60
thousand pieces/ha, middle-ripe – 50 thousand
piece/ha, middle-later ones – 45 thousand pieces/ha.
The scheme is single-row, with spacing of 70 cm. The
application of the studied drug TMTD-plus helped to
reduce the growing season of maize plants for one -
two days. Thus, changing the sowing terms of maize
hybrids and populations, we can largely control the
development of plants changing the length of the
growing season to two weeks and form a harvesting
conveyor, thereby reducing the intensity of field work
The article shows the historically developed situation
and the actual state of the production practice in
chronic mycotoxicosis of a bird. The main feed
problems in poultry farming are shown through the
prism of a review of market proposals for feed
concentrates. An overview of preventive and
compensating agents on the market, as well as a brief
description of feed concentrates based on beta-carotene
for fighting mycotoxicosis. It is shown that the
vitamin-mineral fodder concentrate "Tetra +" is an
alternative to the existing feed concentrates on the
market, the effectiveness of which has been confirmed
in experiments on laboratory animals and in poultry
feeding. Based on the analysis, a conclusion was made
about the relevance of studies to identify the
effectiveness of vitamin-mineral concentrate "Tetra +"
in livestock
The article gives an overview of the current
developments of scientists of the Russian Federation in
the field of production of feed concentrates and
premixes for cattle. A critical analysis of feed
concentrates and premixes of preventive and
compensatory action for the control of mycotoxicoses
was carried out, and their brief characteristics were
given. The characteristic of biologically active
substances and fillers, declared in the recipes of feed
concentrates and premixes, is given. It is shown that
the alternative to existing feed concentrates and
premixes on the market is vitamin-mineral fodder
concentrate "Tetra +", developed by the authors. Based
on the analysis, a conclusion was made about the
relevance of studies to identify the effectiveness of
vitamin-mineral fodder concentrate "Tetra +" in
livestock
