The right balance of essential amino acids and protein is the main condition for the optimization of weight gain, feed conversion and high profits. In VGC "Megamix" the quality of different types of raw full-fat soy, wheat, corn, meat and bone meal and fish was assessed on the content of amino acids on the IR analyzer of FOSSNIR Systems company. Amino acid content in the feed does not always match the average standards of reference. So in the reference data content of methionine, threonine and phenylalanine in wheat, indicated 0.23%, 0.43% and 0.64% respectively, and studied in the laboratory of VGC "Megamix", respectively, 0.24%, 0.45% and 0 73%, that is 0.01%, 0.02% and 0.09% higher of tabular values. The lysine content of the wheat to be investigated in a laboratory and provided in the averaged data was on the same level. Thus, the calculation of the recipes should be carried out taking into account not tabulated values but the actual, which will reduce the so-called "safety stock" to get food of consistent quality and reduce the cost of the cost of animal feed, which in turn affects the economic efficiency of livestock production
The article presents the results for the study of productivity and quality of vegetable crops in irrigated chains of crop rotation by using intermediate and green manure crops. The greatest number of units of grain produced in the first variant of the experiment, where in a part of crop rotation cultivated sweet corn, mustard as a green manure for potato and onion planting summer planting seeds in the ground and reached 37.4 tons of grain units. The infection of potato tubers with complex disease was lowest at the control variant and compose 11 %. The highest infection with diseases of potatoes fixed at the intermediate and without the use of Side-General culture and was 18 %, which is 63.6 % more than the control options. When we are using intermediate crops diseases of onion increased by 7,7–15,4 % in case of green manure using. When you include treatment of the soil under the previous culture it was the largest infest with diseases and was 16–17 %, which is by 23.1 and 30.8 % higher than in the control variant. Based on these results, we can conclude that the use of green manure crops and intermediates more favorable effect both on the productivity of the subsequent crops or the quality and marketability
This article presents the results of the chick peas use instead of sunflower cake, in feeding young and adult livestock hens-layers of the cross "Hajseks brown". The researches were carried out in the JSC "Agrofirm Vostok" of the Nikolayevskiy district in the Volgograd region. The sunflower cake replacement with legumes - chickpeas as the part of the experimental animal fodder for young and adult livestock hens-layers had a positive influence on productivity, physiological state of the birds, product quality and economic performance. Chick peas’ use in young hens feeding improves live weight at 1.03-4.68%, egg production in 0.99-4.7%, the average weight in 0.99-3.75% and eggs quality indicators. Morphological and biochemical indices in experimental young hens and laying hens in all the groups were within the physiological range, indicating normally occurring redox processes in the body of a bird. However, the chick peas’ application in fodder for experimental young hens and laying hens contributed to the increase of total protein, calcium, phosphorus content in serum compared with counterparts in the control group that received sunflower cake. As the researches result, the economic effect in the experimental groups was 833.01-3821.87 rubles
Over the past 15 years due to removal with crops of
rice crop rotation, as well as with field waste and
seepage water content of mobile forms of boron in
soils of rice irrigation systems in the Krasnodar region
decreased by 10 %, cobalt by 14 %, manganese
by 10 %, copper by 7 %, molybdenum by 15 % zinc
by 6 %. Impoverishment of soil with calcium and
sulfur is observable. Need of using micronutrients for
this crop is also determined by lowering mobility of
most microelements in flooded soils. Partly this problem
can be solved by use of neutralized phosphogypsum
– waste product of wet-process phosphoric acid.
With its application in dose of 1 t/ha, field receives
265 kg of Ca, 215 kg of S (general) 20 kg of P2O5
and 9.8 kg of SiO2, so it compensates for the loss of
calcium from the rice soil, as well as solves the problem
of sulfur, silicon and partly phosphorus fertilizers.
Data showing possibility of use of neutralized
phosphogypsum as multicomponent fertilizer for rice
crops are given. Phosphogypsum reduces sparseness
of rice plants in ontogeny, thus forming a dense agrocenosis:
plant density is 24-25 pcs./m2 that is higher
than on application of N120P80K60. Plants with such
agricultural background by their height and leaf area
did not differ from control ones (N120P80K60), and
their dry weight was higher by 2-6 %. With fertilizer
system N120P80K60 application of 4 t/ha of phosphogypsum
during main fertilizer treatment provides
the same level of phosphorus content in the soil and
plants, as application of 100 kg/ha of ammophos.
Rice yield increases by 0,57 t/ha or 8,98 %. Yield
growth is the result of increasing survival capacity of
plants, seed setting of panicle and weight of grain per
plant
The key task of the agriculture in Russia is the further
improvement of grain production. Thus, prevention of
losses of winter wheat yields because of the diseases
remains relevant. The significance of varieties tolerant
to diseases, especially to smut (fungus) is of primary
importance. Therefore, it’s essential to create initial
material for breeding of the varieties tolerant to smut.
According to the results of the trials with artificial
infection with pathogens, among the samples of
winter wheat there have been identified varieties
belonging to different groups of tolerance to smut.
They are a highly sensitive cultivar ‘к-69361’
(Korea), a sensitive variety ‘Izyuminka’ (Russia),
moderately sensitive variety ‘Asket’ (Russia) and
almost tolerant variety ‘1621/03’ (Russia). We studied
the reaction of the hybrids F2 on infection with smut
in different variants of hybridization to obtain stable
progeny. The correlation between the number of
infected plants in parent and hybrid (F2) populations
have been considered. The productive tillering of the
plants has been determined in all variants of the trials;
it was the least one on the plants with 100% of
infected leaves. The hybrids F3 and F 4 have been
distributed according to the degree of their tolerance
to smut. For further work we have selected the lines
with practical resistance to smut (fungus)
The total area of saline soils of rice irrigation systems in the Kuban region reaches almost 80 thousands hectares. Salinization and alkalinization here become a limiting factor for cultivating rice and companion crops. In this regard, the tolerance of plants to soil salinity is a current problem of plant breeding that attracts the attention of many agricultural researchers whereas it is necessary to increase the yield in saline soils. Salt tolerance of crop plants is defined by a combination of properties which are based on the specific adaptation mechanisms. These mechanisms differ in nature and are associated with different levels of structural organization of the plant – from molecular to organismic one. The study of adaptation mechanisms at different levels of structural organization of plants is very important for increasing yield in saline soils. This article is a review giving a detailed analysis of plant salt tolerance research, particularly rice, which addresses the issues of inhibition of plant growth under saline conditions, the mechanisms of salt tolerance, the achievements and development of this branch of scientific research, as well as the application results of work found in the scientific literature
In the article we have proposed the technology of repair works using improved soil mixture sifting the rubble and ash using soil mixture installation and without it. For prevention of occurrence of defects and damages we have offered an antifiltration device
in the form of screen and core from compacted obliquely pulled layers of impermeable soil
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
It was experimentally established, that the inclusion
dietary supplements, based on whey in feed mixtures
for broiler chickens improves digestibility and nutrient
digestibility of feed, which has a positive effect for
live weight of poultry
In the modern wine growing, for fighting against root
phylloxera an inoculation of European-Asian grapes
varieties on rootstocks steady against this wrecker is
used. In this article we present the information about
the types of rootstocks of domestic and foreign
breeding used in the modern branch of wine
growing. The area of their use is described; the
useful properties of rootstocks and their demerits are
highlighted. The purpose of this work is creating new
grapes rootstocks which wouldn't have the merits of
existing rootstocks. The short description of the
grapes rootstocks which were created in the Anapa
Zonal Experimental Station of wine growing and
winemaking such as AZOS-1, AZOS-2, AZOS-3,
AZOS-4, AZOS-5 and AZOS-6 is given in the
article. It is indicated that these rootstocks have a
high resistance to a leaf form of phylloxera, to
chlorosis and to some other diseases of a grapes
bush. They have the short period of vegetation, high
quantity of standard cutting from hectare and other
useful properties. In the article the description of a
new formation of rootstocks grapes bushes of "AOS-
1" and "AOS-2" with a free trail shoots is given. This
construction of grapes bush is developed by the
Anapa's Zonal Experimental Station of wine growing
and winemaking. We have also given all the
advantages of this forming in comparison with other
designs of grapes bushes. It is especially noted that
use of this forming of bushes increases the
productivity per men in the process of bushes scrap
and preparation of cutting; the expenditures on the
struggle against diseases and wreckers on the vineyards are reduced; the quantity standard of
grapes cutting increases by 27-33%
