This article presents the results of the use of feed
concentrate from vegetable raw materials called
"Sarepta" in the amount of 5, 7.5% and 10% by
weight of the feed, instead of sunflower meal in the
feeding of Russian sturgeons. Studies have been
conducted among 3 year old Russian sturgeons in the
conditions of PRIBOY company in the Bykovsky
district of the Volgograd region. The experiment
lasted 24 weeks. Replacing sunflower meal with a
product of processing of oilseeds - feed concentrate
Sarepta, made from vegetable raw materials, in the
composition of feed for sturgeons had a positive
effect on live weight, absolute, average daily and
relative gains and costs of feed. The use of "Sarepta"
feed concentrate, made from vegetable raw materials
in the feeding of Russian sturgeon contributes to the
increase of live weight of 3.1-6.0 per cent, an absolute
increase of live weight by 5.07-9.82 percent, and
average daily and relative body weight increase. It
was also found, that we had a decrease in feed
consumption during the period of experience in the
experimental groups. Morphological and biochemical
parameters in experimental fish in all groups were
within the physiological norm, which indicates a
normally occurring redox processes in the body
In this innovation section there are necessary agrotechnical receptions of care by the vineyard bushes, providing reception of high and qualitative crops of grapes. First of all, these are gartering of sleeves, fruit arrows, vegetating arms; operations with green bodies of a bush, fragmentation, extrapollination, stopping, girdling, stamping, etc., and also mechanization of care works
Petrovsky garden was founded in 1703 and is the most
important historical object of landscape architecture in
Petrozavodsk. Tikhon Balandin made a description and
drawing of Petrovsky garden at the beginning of the
19th century. He completed his work by studying and
measuring the fragments of the earthen fortress, blast
furnace and the location of the destroyed palace, pond
and birch garden. On the basis of the historical
documents, we created a 3D model of Petrovsky
garden using of modern computer-aided design. Threedimensional
model of the garden allows viewing the
object from different angles, gives an idea about
structure and compositions of the garden on a new
visual level. Some examples of visualization garden
fragments were presented at the article. Now the
garden doesn’t have its original structure. The
historical garden layout and 3D model of object can be
used for reconstruction of Petrovsky garden
In the course of the two experiments, it was found that to improve the bio-productive qualities of a broiler chicken grown from rations with a tolerant level of aflatoxin B1, one should incorporate barley grain subjected to ozonation for 3.0 h, and the Hydroxy-Nile
preparation calculated of 600 g / ton of feed in the formulation of the diet
he article discusses postcards with images related to agro-botanic illustration, the possibility of their use as an information resource in the process of the study course on the history of agriculture. We have given the extensive understanding of agro-botanic illustrations, reviewed the goals and objectives of this type of image. History of agriculture in postcards considered on three types of images: art (reproduction and original) and documentary (photo). For each type of images we have illustrative examples with brief comments. The review is presented with a combined collection covering different countries of the world. The article contains examples of postcards with brief comments. It presents an overview of the collection of postcards from different countries, and an analysis of the examples from the series named "Giant vegetables at the farm" and "Apple family". Thus, the images presented on postcards allow us to obtain the following information: the orientation of the agricultural sector areas (main activities: crop production, livestock, horticulture, viticulture, vegetable growing, etc.); Botanical characteristics of crops (agro-botanic illustration; illustration of certain types of technologies of cultivation of crops (cleaning, plant care, plowing, irrigation); documentary image separate record harvests; historical and cultural traditions associated with the agricultural sector, or in separate areas; the promotion of new crops, varieties, and hybrids of agricultural plants and flower crops; information about crops grown in the region, state, specific areas; paintings covering the agricultural labor of a particular country; promotion of local flora; develops observation; teaches us to think and analyze the information
The results of studying of the maintenance of lead and cadmium in soil and agricultural crops at use of various agrotechnologies are presented in the article. The negative tendency of accumulation of heavy metals in winter wheat grain is noted
The article presents the results of diagnosis of soybean plants with sulfur, molybdenum and boron in a Western Ciscaucasia on leached chernozem (black soil). The soil testing has shown that the availability of sulfur in the experimental plots is low (2,10-7,02 mg / kg), molybdenum - average (0,20-0,28 mg / kg), boron - low to high (0, 22-0,63 mg / kg). The sulfur content was optimal in 2013 (2309 mg / kg), molybdenum - 2013 and 2014 (1.11 and 0.94 mg / kg) and the boron content was high (65,2-94, 1 mg / kg) in soybean plants. The soybean plants needed sulfur fertilizer in 2012 and 2014, molybdenum - in 2014, and boron fertilizers are not needed, according to the functional diagnosis. The results of various methods of diagnosis coincided with the response of soybean plants for foliar application: sulfur fertilizer increases the yield in 2012 and 2014 by 7.1 and 8.9 %, molybdenum also in 2012 and 2014 - by 6.0 and 10.0 %. Boron fertilizers in 2014 increased soybean yields (17.1%), despite the lack of need for soybean plants in Bor. So, the method of functional diagnostics is more accurate than chemical soil and plant diagnostics
In this article the influence of agrotechnologies of cultivation of field cultures on soil indicators and distribu-tion of heavy metals on the horizons of the black leached soil is considered. Regularities of distribution of gross and mobile forms of manganese, zinc, lead, cobalt, copper and cadmium on the genetic horizons of the black leached soil of the Azov-Kuban lowland are revealed
The leading place among different methods of clone selection of grapes takes the method of professor A.S. Merganian. This method is put the base of modern clone selection which provides a reliable results on practice.
There was cleared up the mechanism of fecundated fruit-plant stimulation on the basis of biochemical analysis of flowers. There was substantiated the agricultural method directed to the optimization of the given process.
