In the article, we have revealed the efficiency of sown using of fertilizers, the methods and the doses of additional fertilizing on different maize subspecies growing on the leached black soil of Northern Ciscaucasia which are based on studies in central part of the Kras-nodar region in 2008-2010. We have also given the scientifically-based references of increasing productiv-ity of maize
In the article the results of the influence of various types of hybrids and their variants of sterilization on efficiency of sugar beets are shown, and also their economic estimation is given
The article describes the efficiency of a feed additive
called "Tetra+" during chronic mycotoxicoses of pigs.
The purpose of carrying out series of experiments on
sows was to determine the therapeutic and
prophylactic effectiveness of innovative feed additive
"Tetra+" during combined chronic mycotoxicosis in
pigs and to study the influence of feed additive on the
growth, weight, preservation and overall resistance of
sows. The results of the experiments revealed that a
feed additive "Tetra+" has had a positive impact on
large-fruited of pigs; it can also be concluded that the
feed additive "Tetra+" has a positive effect on the
metabolism of proteins, carbohydrates and has
antitoxic properties
Winter wheat is very demanding on the nutrient regime of the soil. Like many winter crops, it consumes the nutrients unevenly distributed during the vegetation period, which must be considered when making them. Modern varieties of winter wheat are very demanding to soil fertility. For the formation of 4,0-4,5 t/ha requires about 140 kg of nitrogen, 50 kg phosphorus and 120 kg potassium. Therefore, without the use of fertilizers, it is not possible to obtain such a crop with high grain quality. In addition, in the cultivation of winter wheat in the high and intensive technologies simply need using large amounts of fertilizer to compensate for the removal of nutrients. This is especially important when having partial or complete reduction of application of organic fertilizers. Therefore, we consider the possibility and the results of studies using different doses, combinations and types of fertilizers in technology of winter wheat cultivation. Experimental studies were carried out in the conditions of insufficient and unstable moistening of southern zone of Rostov region, on experimental fields of the federal state scientific institution «ASС «Donskoy». For research, we have chosen the most common varieties of winter wheat (Tanais, Granite, Axinite, Terra, Donskoy prostor, Motto) and various combinations and combinations of mineral and organic fertilizers. The experiments were conducted on two predecessors: couples and peas. As the controllable parameters we had the productivity and quality of winter wheat. We have found a positive impact of the in-change of fertilizer on the studied parameters with a share of the variance of 96% and a high degree of correlation of 0,98. The marked increase in the productivity of winter wheat is up to 22% when using different versions of the experiment. We have identified rational combination doses of mineral and organic nutrition for predecessors: peas N40P60K40+2N30 and vapor – manure 40t/ha+2Р60+2N30
In this work, the influence of "Topinambur" and "VitaSelen" nutrition additives on productivity of pigs and food meat value is presented, as well as on morphological and chemical composition of blood
Complex actions are created for the improvement of soil conditions in cultivating of young plants of stone crops with application of organic and mineral substratum. Economic factors and efficiency of tested actions are reviewed
The article presents the biological growth of above-ground parts in a nursery open ground. It gives the economic evaluation of the production of seed species and varieties of juniper, depending on the category of the source material
In adverse dry weather conditions the yield of traditional crops is sharply reduced, particularly of maize, therefore it is required a drought-resistant crop with high forage characteristics. This crop is the grain sorghum. The presence of non-starch polysaccharides in sorghum grain creates the preconditions for the inclusion of enzyme preparations in the combined feed for broiler chickens. The aim of the study was to provide high productivity of the broilers fed the combined feed, containing up to 30% of grain sorghum with the additional use of the enzyme preparation "CelloLux -F". Positive results are achieved both in productivity and digestibility of the main nutrients in the combined feed with the enzyme. It is recommended to include the enzyme into combined feed for broiler chickens at the amount of 100g/t of feed. Application of enzymatic agent "CelloLux -F" as a component of combined feeds for broiler chicks favors live weight gain, feed conversion efficiency and safety of young birds. It is recommended to include the enzyme into combined feed for broiler chickens at the amount of 100g/t of feed
The newest wine grape variety Eftihiya with aromatic pink colored skin (in Greek the name means “happi-ness”) was breed with hybridization at the Athens In-stitute of Viticulture by P. Zamanidi, L. Troshin and P. Radchevskiy in 2005 by crossing the Greek varieties and Malaguzya with Eurasian Traminer pink. Dura-tion of production period from bud burst to harvest 146-155 days. Yields are very high: 25-30 t / ha. Modal mass of clusters is 250 g. Bunch is conical, me-dium density. Berry is medium, short elliptical, pink colored, with a thick wax coating. Pulp and juice with the expressed varietal flavor, similar to the aroma of Traminer pink. Sugar content of more than 24%. Vari-ety is designed for production for the dry white wines of excellent class and high-quality sparkling, dessert and sweet wines; suitable for the production of high quality aromatic juices
Poultry farming is characterized by a relatively low cost of production, so it is more cost-effective compared with other sectors of animal husbandry. However, the feed of plant and animal origin used in the poultry industry does not always correspond to the requirements of biological safety and are subject to damage by fungi producing mycotoxins, causing extensive economic damage. Therefore, to improve the performance of the cultivation of chickens broilers was used natural sorbent - ekobentokorm (from the local cheap raw materials - bentonite clay), which is not only a source of macro - and microelements, but also with adsorptive activity in respect to mycotoxins, endotoxins, salts of heavy metals and pathogenic microflora, improves digestion and metabolism
