The article presents the indicators of the protective afforestation in Voronezh region, biometric growth index, agricultural and environmental impact of forest belts, efficiency of agro territories
The article presents the indicators of the protective afforestation in the Central Chernozem region, particularly the growth of various tree species in pure and mixed composition of forest belts, influence of field protection plantings on environmental conditions of surrounding agricultural landscapes
The article discusses the development of piglets in utero using irradiation lamps IK -250 and BUV – 15
Distinctions of soil under a winter wheat after a winter wheat and common sainfoin in provision of moisture and feed elements are revealed. Influence of autumn application of complete fertilizer and spring nitric dosage compensations on productivity and quality of a winter wheat are established; dependence of fertilizers’ effect from nitrate nitrogen contents in the soil is shown. Optimum dozes combinations on both predecessors are found
In 2010-2012, in a field experiment, the research on the effect of fertilizers on physic-chemical, agricultural chemical and biological parameters of soil, as well as their impact on the dynamics of the content of major nutrients in soybean plants and its yield was conducted
Using the method of rapid assessment of the environmental state on the Steel of pollen-bioindicators test-system the study was conducted to determine fertility of male gametophyte of soft wheat in the conditions of herbicide load
Application of enzymatic agent MEK CX-3 (as a component of combined feeds for broiler chicks) promotes live weight gain, feed conversion efficiency and safety of young birds
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
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
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
