In this article, we present the results of the experiments on
the potential of productivity and accumulation of the root
mass of the Alfalfa and Brome-grass, on the content of the
main nourishment elements and the consolidation of gross
energy in the roots and agroenergetical effect of the
collected gross energy in the conditions of permafrost turf
soil of the Middle Lena valley. The maximum productivity
potential of beans and cereals grass mixture was reached
on the basis of the organic mineral nourishment regime:
the collected exchange energy – 21,3 GJ, feed units – 1568
and collected raw proteins – 428 kg per ha. Thus, the
content of digestible protein in beans and cereals grass
mixture agrophytocenoenosis was increased from 118 to
124 g, that exceeded a zootechnic norm (105 g). In general
the nitrogen contained in the total root mass of beans and
cereals grass mixture agrophytocenoenosis was up to 26,6
centner per hectare and movable phosphorus- up to 33,6 kg
per hectare that can serve as the source of nourishment for
sown herbs. The maximal stock of gross energy in roots
was got in beans and cereals grass mixture
agrophytocenoenosis at organic-mineral degrees (humus of
40 centner per hectare once in 4 years + of N120PK60
annually) up to 157,1 GJ/ha, while the accumulation of the
root mass reached 140,3 centner per hectare at average
annual rates of accumulation of dry substance up to 24,5
centner per hectare. The processes of formation,
decomposition and death of roots in the beans and cereals
grass mixture agrophytocenosis take place almost in a
balance state. Wherein the biological factor, as the
inclusion of the Yakut yellow variety of the Alfalfa in the
grass stand, plays a positive role
In this article, agrochemical properties of the mining rocks at the industrial embankment of Kursk Magnetic Anomaly and pine indices of growth have been analyzed. A conсlusion has been made about the impossibility to grow long-term pine plantation without substrate fertility increase measures
This article shows the peculiarities of an apple-tree organogenesis in gardens of intensive type. There was collected the agronomic way directed to the optimization of the given process
The extensive path for development in the country in the
twentieth century caused low competitiveness of
Russian pig production. The productivity of domestic
pig production was significantly lower than in Europe,
US, Canada and China. Feed costs per 1 kg of gain were
2-3 times higher with a low yield of piglets from a sow
per year: 14-16 with an average European 25-27 heads.
The country did not have enough meat; as a result, a
significant amount of meat products was imported to
Russia. Restrictions on imports in connection to the
imposition of embargoes contributed to the increase in
demand for domestic products and opened new
opportunities for Russian producers. One way to
increase the production of pork is to use pigs with a high
genetic potential for productivity, imported for breeding
from Canada and Europe. Based on the conducted
studies, it has been established that pigs of foreign
breeding have high reproductive qualities, which proves
the expediency of their application in commercial pig
production to increase the efficiency of the industry
development and reduce the import of pedigree
youngsters from abroad. The implementation of two
breed gilts will help increase productivity in the
industrial pig production
The article gives theoretical and practical justification of sorghum use in animal feeding. The results of the study of organization of forage resources for livestock and poultry with the use of forage sorghum are shown. The ways and directions for the increase of nutritive value and productive effect in the diets for animals and poultry are determined
The newest wine white-berry fruitful high-grade breed of grape - Pontos is bred in Greece P.Zamanidi and L.Troshin in 2003 by mating of the Greek breed of Sideritis with a breed of Sovignon. Duration of productivity phase is 156-165 days. A breed is tall. A degree of vines ripening is very high. Productivity is very high, 15-16 t/hectares and more. The medial mass of racemations is 390 gr. Differs with high winter-hardiness, drought resistance and raised sustainability to fungous diseases in comparison with breeds Vitis vinifera. A flower is bisexual. Racemations are big, pencil-point, with medial denseness. Baccas are average, circular, greenish-yellow color, with a dense wax coating. A peel is tight. Pulp and juice with the expressed high quality flavor. Sugar content is high. It dries when over-ripening and stays on bushes. Under morpho-physiological characteristics, it is included in ecological-geographical bunch of breeds of basin of Black sea. The breed is designed for production of dry white wines of the excellent class, and also high-grade sparkling wines; it is applicable for production of high-grade juice and compotes as well
The results of sunflower cultivation comparative analysis in the traditional system and direct seeding are given in the article
The need of improving the grain drying technology is
due to a significant volume of this operation, high
specific energy and high standards to preserve quality
of grain. In this regard, the development of new
technologies and equipment aimed at reducing the cost
of fuel and electricity, providing the preservation of
grain quality has essential meaning to reduce the
drying cost. Usually, the electrophysical effects on the
dehydrated material not only contribute to the
thickness reduction or destruction of the boundary
layers and increase the surface of phase contact, i.e.
they cause the combined effects of the intensification
of the drying process that is economically favorable
and they say for a broader practical use of
electrotechnologies. Method of grain drying using
microwave recycling in installations of active aeration
bunker type allows increasing productivity compared
with standard technology for up to 30% and reducing
process energy consumption by 17%
There was given a review of the results of the study in
the conditions of sufficient moisture of Central
Ciscaucasia, the influence of planting terms and
presowing seed treatment by the drug called "TMTDplus",
containing Krezatsin growth stimulator 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 middle- maturity 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 of the
experimental station of StavrGAU was presented as
leached black soil. 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, middleripe
– 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 - four 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
Solving of problems of the influence of irrigation on ecological situation and creation of optimum land-reclamation conditions are impassible without using of the mathematical modeling methods.
The work provides the idea of solving of the land-reclamations problems with the using of systematic-cognitive analysis.
