In this article, the results of researches of the influ-ence of terms and norms of crops of a winter rape on growth and development of plants, winter hardi-ness and productivity of cultures in the changed environmental conditions of Rostov region are re-sulted
This article presents the results of the research of soil cultivation practices and the herbicide treatment ef-fect on the weed content in maize grain crop grown in the stepp conditions of the Krasnodar region. It has been determined that tillering soil with the Wil-Rich disc harrow at 10-12 cm depth is less effective than fall ploughing with a top layer turning-over, chisel and disc tillering combined with summer herbicide treatment. The latter give the advantage of less weeds and higher grain yield
In the article, there are the data of a specific variety of cereal weed plants in crops of winter wheat on a black leached soil depending on the predecessor and the way of processing of a soil and its role as a source of an infection root rot. The greatest number of isolates of mushrooms – causative agents of a disease, was allocated from such weed plants as wheat grass creeping, eras galli, field (chess) brome grass; the smallest – from Lolium temulentum. Fusariosis root decay dominates in community of cereal weed plants
There were reviewed the results of the study of the
dependence of main phenological phases of
development of corn hybrids of different maturity
groups of the selection of Krasnodar Research Institute
of Agriculture named after P.P. Lukyanenko in the arid
zone of Central Ciscaucasia (Ross 199, Ross 299,
Krasnodar 382 and Krasnodar 410) and the AllRussian
Research Institute of Corn (Mashuk 170,
Newton, RIC 345 and Eric), as well as early-middle
Rossiyskaya 1 from the changes of average daily air
temperature of planting dates and preplant seed
treatment by the preparation "TMTD-plus", containing
the growth promoter called Krezatsin in its
composition. The studies were conducted in
accordance with the thematic plan of scientific
researches of the department of crop and forage
production of Stavropol State Agrarian University. The
technology of maize growing on the experimental plot
corresponds to the standard technology for this area
and culture. The sowing was performed in three stages.
The first (early) sowing period was at t = + 7 ... +8 °
C. The second (recommended) – was at t = + 10 ... +
12 ° C. The third (later) sowing period was at t = +15 °
C. There was identified a high inverse correlation
between the average daily air temperature and the
duration of the intraphase periods of maize
propagation. Thus, at the shifting of maize sowing
dates with the second half of May on the second half of
April we have optimization of heat regime in the
generative period and rising of the efficiency of use of
thermal resources of the region. There was marked the
acceleration of development of corn seedlings when
the average daily air temperatures was up to 12 ° C at
the samples with the application of the disinfectant
TMTD-plus
The successful development of livestock requires
maintaining and further increasing of the genetic
potential, the basis for the manifestation of which is
the adequite balanced feeding. Currently, one of the
most urgent problems of livestock breeding is to find
ways for reduction of the negative impact of various
feeding factors on the animals. In industrial
conditions, it is difficult to exclude various feed
stresses, which lead to a decrease in productivity,
survival rate and ill health of animals and poultry.
The work summarizes the research in this direction,
taking into account the achievements of domestic
and foreign authors. A serious problem of feed
producing companies and livestock farms is the grain
and compound feed affection with fungi and their
metabolic products - mycotoxins. Based on the
results of the research of several authors, the ways of
solving this problem were identified and
recommendations on the reduction of the negative
effect on the body were provided. It is noted, that
one of the best and effective ways to reduce the
negative effect of mycotoxins on the body is a
method of administration of adsorbents in animal
feed. But it should be taken into consideration that in
order to maximize the protection against mycotoxins
and minimize their harmful effects on the body of
animals it is necessary to use preparations, which
include adsorbents of organic and inorganic nature,
as well as to comply with the dosage of their
introduction into the diets of animals and poultry.The
progressive forms of preparations of a new
generation, solving problems of the negative impact
of feeding factors, include probiotics, which contain
some bacteria, immobilized on the solid particles, so
that they inhabit the intestine faster. Modern
biological complexes have immune correcting
properties, increase non-specific resistance of the
organism, normalize microbiocenosis of
gastrointestinal tract, and stimulate the functional
activity of the digestive system. Therefore, it is
necessary to use feed additives with detoxification
properties as part of animal compound feed,
according to recommendations on their application in
appropriate dosages
The positive effect of soybean oil meal in combination with biologically active substances on productivity and meat quality was determined in the experiments with young pigs
Our introduction of the enzyme preparation MEC-AGRICULTURE-3 into the mixed fodder for young pigs favors increase of live weight by 6.0 % and average daily weight gain by 7.8 %
The article has a presentation of development of a technological complex, with development of initial requirements of utilization of not grain part of a crop of rice with seal to the soil
Influence of system of the basic processing of soil and system of fertilizers of a sugar beet on accumulation of the general and productive stock of a moisture in the beginning and in the end of vegetation, total water consumption and water consumption factor, and also influence of these agro receptions on productivity and sugar content of root crops is studied
Since 2009, we studied the conditions for obtaining of winter wheat with prescribed technological properties
