For the production of high quality winter wheat grain,
it is necessary to observe the technology of growing
the crop and creating optimal conditions for the growth
and development of plants. An important role in it is
played not only by agrotechnical measures, but also by
effective protection of crops from pests. The
phytosanitary state of winter wheat sowings has
worsened significantly in recent years, however, the
degree of damage to crops and the harmfulness of
fungal diseases can be significantly reduced, and in
some cases completely prevented by treatment of crops
with fungicides. The range of fungicides is improved
annually by incorporating more effective and less
environmentally hazardous preparations. The research is aimed at determining the optimal rates of
consumption, the biological effectiveness of new
fungicides and assessing their effect on the yield of
winter wheat. As a result, it has been established that
treatment with Abucus Ultra with a rate of 1.0 l / ha
has protective properties, but does not treat plants
(72.2%). This further leads to a loss of an average of
about 0.5 tons of grain per hectare. Fungicide Akanto
Plus in the investigated rates of consumption has good
protective and eradicating (healing) properties and
with a decrease in the rate of consumption of less loss
of yield. Thus, the choice of the preparation and its
consumption rate should be based on an understanding
of the phytosanitary situation, taking into account the
condition of crops and the agroclimatic situation
The work on the study of the biological assessment of environmentally safe herbal feed additives for quail has found in the supplement that contains the seeds of soybean varieties Valens, the bird had higher growth rates than in the supplement of soybean varieties Vila. Using as a protein-based supplement
autoclaved soybean Valens varieties increases the profitability of meat quails from 22.52 to 28.76%, and the economic effect when used - to 32.5 rubles per 1000 quails compared with the addition made from soybean of Vilan varieties
The article represents the results of the experiments on biological activity of humits of different sorts. The object of research was humic preparation called Vermistar, which was obtained by vermiculturing, on the basis of brown coal. Humics are group of high-molecular substances which have high physiological activity. Humic substances stimulate all biochemical processes on all the stages of plant growth. They change the permeability of the cell membranes, increase activity of ferments, amount of chlorophyll and productivity of photosynthesis. Also humits are not toxic; they don’t have carcinogen and mutagenic effects, so we have a chance of getting environmentally friendly products. The experiment results show high biological activity of humic preparations. Usage of humic stimulates germination, the accumulation of vegetative mass, weight gain. The frequency of shoot has been increased by 17-32%. Height of shoots, roots and vegetative mass has also been increased
The article provides a review of biological traits that could be useful for selection of the walnut in diverse conditions of its growth. The most important aspects of species biology are described as they are of primary importance for breeding programs in the countries with
walnut crops
In the article we show the history of opening of selenium, its distribution in the nature, the value of this microcell in life of plants.
We also show the experience of russian and foreign scientists on studying of the influence of selenic fertilizers on a crop and quality of crops
The article presents the bioenergetic efficiency of cultivation of alfalfa of 2 and 3 years of life at various technologies and methods of cultivation of primary tillage
The influence of the crop rotation type, predecessor and different doses of mineral fertilizers on the yield of winter wheat varieties was investigated and bioenergetics estimation was given. Investigations were carried out in the North-Kuban Agricultural Experiment Station in two ten field crop rotation: grain tillage and grain - grass tillage rotation of prolonged stationary experience. The soil is the black soil, low in humus, powerful, with humus content (0-30sm), depending on the power of nutrition backgrounds in the arable soil layer. It was found that the selection of predecessors and the differentiated application of mineral fertilizers ensure stable high yields of grain and they exceed the varieties without fertilizers by 40-79%. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. A strong correlation between yield and agronomic methods was determined. The most effective predecessor for the wheat cultivation by the turnover of furrow slice is sainfoin, peas and wheat. More labor intensive and energy-consuming predecessors are grain maize and sugar beet
The article outlines bio ecological properties of the European cedar, important for the selection of the total seed production, principles of selection varieties of clones. A description of the first grade-clone “Carpathian” is given
The article contains results of the study of biochemistry of some perspective table grape varieties: Aniuta, Vodograi, Nizina and Jubilee Novocherkasska, yield in 2013 from the Central zone of Krasnodar region. At the time of redy yield the combination of sweetness and acidity of fruits were favorable. The ratio of fructose to glucose was 1.69; 1.36; 2.00; 1.13, respectively, in grapes Aniuta, Vodograi, Nisina, Jubilee Novocherkasska. According to the percentage of fructose in fruit juice varieties Aniuta, Vodograi and Jubilee Novocherkasska close to each other (50.93; 56.14; 51.23%). According to the percentage of glucose similar varieties Aniuta and Nizina (33 - 34.27%), Vodograi and Jubilee Novocherkasska (41.16 - 45.22%). Sort Jubilee Novocherkasska, had content in berries close fructose and glucose. Most of fructose (66.02%) in berries variety Nizina. In berries studied cultivars organic acid content was: wine 3128 - 3861, malic 982 - 3753, citric 109 - 317, amber 3 - 115 mg / dm3. The highest concentrations of potassium and sodium cations are presented in berries varieties Aniuta: potassium - 1219 sodium - 35.13 mg / dm3 and cations magnesium and calcium in berries Jubilee Novocherkasska 46.75 and 73.64 mg / dm3. The lowest concentration of potassium and sodium cations observed in grape Vodograi, magnesium - from grape Aniuta, calcium - at grape Nizina. We studied grape bunches are large, not dense, beautiful, berries are large, harmonious taste. Tasting score fresh grapes varieties Aniuta, Vodograi, Nizina, Jubilee Novocherkasska 7.6; 7.4; 7.8; 7.8 points respectively
