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
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
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 agricultural industry is subsidized sector of economy, besides a certainty is that agrarian production in the Russian conditions can't be conducted without considerable support from the state. Today the agricultural industry is the most important element of the market and the animator of development of economy. With respect there to upgrade of state policy in agro-industrial complex, considering the basic principles of development of an industry is necessary. In article indicators of increase in efficiency of use of means of the state support of producers of an agricultural industry of Russia are considered. Effective rendering the state support of an agrarian industry allows implementing established by the doctrine of food security, the state strategy, creations of rural infrastructure, recovery of agricultural mechanical engineering and streamlining of a land ownership. It should be noted that results of the given state support of agricultural industry of Russia in the main directions of an industry: plant growing, livestock production, poultry farming has the heterogeneous level of efficiency which is reflected indicators of achievement of level of self-reliance main products of food and achievement of the level established by the doctrine of food security of the country. A necessary condition of creation of dynamically developing and competitive industry in the world and domestic markets is a fixed growth in volumes of the state support, upgrade old and development of new programs of support of the village and agricultural producers
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
The results of laboratory experiments on the effect of different concentrations of SkQ3 (10- (6'- methylplastoquinonyl) decyltriphenylphosphonium) on the rate of growth of spring barley seedlings of varieties Sokol and winter wheat varieties Kalym in normal and under inadequate moisture conditions, as well as data from field experiments on the effect of pre-sowing processing SkQ3 on the morphometric indices of spring barley varieties Shhedry, hard winter wheat of the Lazurite variety and soft winter wheat of the Lydia variety are presented. As a result of laboratory experiments, an increase in the growth rate of 14-day-old seedlings grown in solutions of polyethylene glycol was shown when treating the seeds with 2.5 nM and 25 nM with SkQ3 solutions.
In the field experiments on the pre-sowing treatment of SkQ3 seeds, an increase in the morphometric indices of spring barley varieties of generic Lydia soft winter wheat and hard Lazurite winter wheat has been established, as well as an increase in the yield of winter wheat of both varieties as compared to the control
In the article, the estimation of efficiency of selection on high tillering is given at various planting density. For the analysis used plants of variety Lampo with high tillering ability and varieties the Virazh and Ko-mandor - with weak tillering ability, and hybrid popu-lations F3 from their crossing, selected on traits high and low tillering from F2. Plants ¬ placed on plots in three variants: 2×15, 15×15, 30×30 cm. It is estab-lished that distinctions on tillering between “+” and “–” selection in following generation remain, though the value of given trait at hybrid plants decrease. Selection of highly tillering forms at usual density (2×15 cm) has shown high efficiency, because the tillering is caused by more influence of genetic factors, than environment in the given variant
