The researchers of the institute are studying adaptive power of 17 varieties and 6 lines of winter wheat sown after peas using various methods of assessment of their adaptive properties. During the years of study (2012-2014) we found out that environmental conditions which account for 78% have the greatest effect on the trait ‘grain productivity’ in the formation of the yield. The share of genes accounts for 9,7%, the specific correlation ‘geno type x environment’ accounts for 10% which allow calculating adaptive properties. It has been defined that productivity of winter soft wheat changed a lot due to growing conditions and characteristics of varieties. The productivity ranged from 38,7 c/ha (‘Garant’ in 2014) to 76,5 c/ha 9’Lilit’ in 2013). The study found out that the varieties ‘Stanichnaya’, ‘Asket’ and ‘Lilit’ possess the highest response to cultivation with bi=1,15; bi=1,18 and bi=1,25 respectively. The varieties ‘Lilit’, ‘Krasa Dona’, the lines ‘430/07’, ‘260/09’ and 771/09’ possess a high adaptive ability and productivity with 111%, 105%, 108%, 105% and 106% respectively. The study of adaptive properties of winter soft wheat varieties gives an opportunity to distinguish adaptive, stress tolerant varieties with plasticity according to the primary structural elements which form productivity. The varieties ‘Asket’ and ‘Lidiya’ are characterized with high response to cultivation in different environmental conditions. The varieties ‘Lidiya’ and ‘Kapitan’ belong to adaptive cultivars. The varieties ‘Kapitan’, ‘Krasa Dona’ and the line ‘234/07’ are stress tolerant according to the trait ‘grain productivity’; the varieties ‘Kapitan’, ‘Krasa Dona’, ‘Lilit’ and the line ‘771/09’ are stress tolerant according to the trait ‘number of seeds per a ear’; the varieties ‘Lilit’, ‘Krasa Dona’ and the line ‘771/09’ are stress tolerant according to the trait ‘weight of seeds per a ear’
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
The article considers the results of the evaluation of
the photosynthetic activity of peach trees in intensive
plantations on clonal rootstock VVA-1 in the
formation of improved cupped spindle-shaped
crown. It is established that in the formation of
spindle-shaped crown all the parts of it have just the
right lighting, the leaves contain more chlorophyll,

The studies revealed that the application of spirits as a
strength agent of 91.0 - 96.6% in special wines
contained more vitamin-like substances than wine,
alcoholized with double-distilled water with 75%
alcohol concentration. The highest marks for tasting
wines were given to the options made with the use of
rectified grain origin alcohol as an agent of alcohol.
Application of double-distilled water wine leads to
accumulation of unnecessarily high undesirable
groups of compounds such as methanol and fusel oil,
thereby reducing the quality of the wine. Organoleptic
parameters were the best for selection of wines from
Anapa ZOSViV - Dionysus and Krasnostop EPA, as
well as - Cabernet Sauvignon. We can conclude that
for the production of high-quality red dessert wines
we need, along with the classic varieties, wider use of
new autochthonous varieties using alcohol agents of
rectified grain origin

The problem of environmental safety of agricultural
products and agro-technical measures is very urgent
now. Various agrochemicals are widely used in
agricultural production: plant protection preparations,
fertilizers, stimulants and plant growth regulators, etc.
One possible solution of this problem may be a partial
replacement of mineral fertilizers by bacterial ones.
The aim of our research was to determine the effect of
different fertilizers and methods of their application on
the quantity of microorganisms in the apple root
rhizosphere soil. The research was carried out
according to conventional methods. In our experiment,
we determined the number of microorganisms in the
rhizosphere of the roots of apple trees, nitrogen,
phosphorus and potassium in the leaves; hydrolysable
nitrogen, available phosphorus and exchangeable
potassium in soil and crop yield. The highest yield was
obtained by fertigation in our research. Application
bacterial fertilizer to the soil ensured yield increase at
the level of mineral fertilizer application. Application
of fertilizers in general, in the studied application rates
provided optimum level of nitrogen, phosphorus and
potassium content in the leaves and soil. By use of
fertigation and bacterial fertilizers were high and
relatively stable numbers of microorganisms in the
rhizosphere of the apple trees. The number of
microorganisms in the rhizosphere had a positive
correlation with yield and the content of nutrients in
soil and in leaves
Nitrogen supply of soils is an important factor in the successful cultivation of agricultural crops. Nowadays, in the Central Black Earth region there are planted orchards with high density of trees, with installed systems of drip irrigation and fertigation. Such orchards are relatively new, particularly in this region. Fertigation ambiguous effects on soil structure and its content of nutrients, especially hydrolysable nitrogen. Therefore, the study of the distribution of hydrolysable nitrogen in the soil under the influence of fertigation and drip irrigation is important. The aim of our research was to investigate the distribution hydrolysable nitrogen in the root soil layers 0-20, 21-40, 41-60, 61-80 cm. Investigations were carried out according to conventional methods. In these layers of the soil, we have determined the content of hydrolysable nitrogen and yield. As a result, we have found that in variants with fertigation were the highest yield. In addition, with fertigation it was noted higher content of hydrolysable nitrogen in the soil as compared with the control without irrigation, especially in the deep layers 21-40; 41-60 and 61-80 cm. It was also noted increase of hydrolysable nitrogen in the soil along the periphery of the wetting
In the technology of cultivation of sugar beet the significant role is allocated for system of fertilizer. The research problem included studying of influence of various norms and combinations of mineral fertilizers on productivity and quality of this culture. In 2012-14 the stationary field experiment with sugar beet of a grade of "Nero" on an experienced field of department of agrochemistry in educational economy "Kuban" was put and made. Studying of the nutritious mode of the soil is one of the most important questions of determination of effectiveness of fertilizers. Researches showed that the application of double doses of nitrogenous, phosphoric and potash fertilizers, and also the complete fertilizer in double and threefold dose on the chernozem lixivious, has essential positive impact on the maintenance of like elements of a mineral delivery, providing the favorable food mode during body height and cultural development. Fertilizers promoted more intensive intake of nitrogen, phosphorus and potassium in plants of sugar beet. The maximal maintenance of these elements is observed in a phase of clamping of rows. In experience the good harvest of sugar beet was received. Average productivity made about 450 c he (the increase makes ot13,6% to 77,4%). The maximal productivity of root crops is received at importation of N80P80K80 and N120P120K120 also made 620,3 and 633,3 c/he. Our researches showed that sugar content of root crops by options of experience fluctuated from 14,0 to 18,7%. The best results are received in options with importation of N80P80K80 - in these options sugar content made 18,7%.Thus, optimum conditions for sugar beet are created at importation of the complete mineral fertilizer at the rate of N80P80K80
