Problem of agriculture ecologization in Russia (Belgorod model)
V.I. Kiryushin 
Summary. Based on the review of world trends in agriculture development there were formulated several conclusions. The solution of agriculture ecologization problem is joined to development of adaptive intensification based on knowledge-intensive agro-technologies and wider application of biological methods. Prospects of organic agriculture application in its “pure form” are very limited. For the development of ecological agriculture certain economic, social and cultural preconditions, as well as high enough professional level of producers are necessary.
It was pointed out, that a profound failure in rural economics was demonstrated in Russia, in spite of strong manufacturing and resource potential. It was noted the necessity of urgent work for technological modernization of agriculture, and the availability of necessary preconditions for this task as a methodology for formation and design of adaptive-landscape farming systems and knowledge-intensive agro-technologies, where adaptive intensification and agriculture ecologization integrate. The conceptual approaches outlined in the target program "Introduction of biological farming system in Belgorod region for 2011 – 2018" were high estimated, and also some suggestions to its development from the perspective of adaptive-landscape agriculture were made. According to these attitudes biologization is the main expression of ecological farming. The necessity of establishing regional land survey is substantiated and its main tasks and functions are called.
Keywords: agriculture, ecologization, biologization, adaptive-landscape system, Belgorod region.

Role of crop rotations in the structural organisation of an arable layer chernozem of leached in the conditions of a forest-steppe zone of Zauralye
D.I. Eryomin, A.N. Moiseev 
Summary. Researches were spent for the purpose of studying of influence of various crop rotations on agrophysical properties old plowing chernozem of leached. It has been established, that in the conditions of a forest-steppe zone of Zauralye grainfallow the crop rotation does not influence its structurally-modular structure of an plowing layer — the factor structure has made 2,7-2,8 at the average diameter of units of 3,6-3,7 mm; the content of aggregate stability of 0,25-10 mm for rotation has decreased with 51,5 to 49,2 % that is insignificant. Rotation gpain-gpass with annual grasses of a crop rotation promoted deterioration of a structural condition — the factor structure has decreased for 10,9 % concerning initial values, and water stability agronomy valuable aggregates has decreased with 50,0 to 47,8 %. The increase in a share of perennial grasses in a crop rotation positively affects structurally-modular structure of chernozem of leached — the factor structure for crop rotation has increased to 4,4 unins. The grasses crop rotation strengthens primary structurization — for rotation the content of aggregates in the size less than 0,25 mm have decreased with 44,3 to 35,3 %, and the average diameter of aggregate stability has increased with 1,7 to 2,0 mm that corresponds to values of virgin chernozem of leached.

Indicators of soil fertility as diagnostic parameters of agricultural land damage
V.I. Titova, A.G. Samodelkin, E.V. Dabakhova, A.A. Vetchinnikov
Summary. The aim of this work is the formation of the list of the most informative diagnostic indicators that can be used in assessing the degree of land. The studies were carried out on the sod-podzolic and light-gray forest soils of light granulometric composition, damaged due to the construction-repair works on trunk oil pipelines. It is established, that the morphological analysis of the soil profile allows to prove the fact of compliance (non-compliance) with technology works in the part of protection of the fertile soil layer. The most reliable diagnostic indicator, characterizing the degree of negative impact on the soil is humus content, which on average in the studied damaged soils is 2,5 times less, than in the background soil. Changing the content of biogenic elements, as well as the acidity in damage of the land is not always clearly defined and depends not only on the extent and nature of the impact, nor of the properties of subsoil, raised to the surface as a result of works, as well as the degree of the original soil cultivation. So, the maintenance of mobile potassium in damaged light-gray forest soil has decreased in average from 134 to 84 mg/kg, and in sod-podzolic soils increased from 38 to 82 mg/kg. The density of the soil in average in the broken site, as a rule, not more, than on the background but the range of variation of the indicator in damaged soil is substantially expanded. The biological activity of the deterioration of soil properties observed in damaged soils, in most cases decreased relatively to the background, which, however, may not be revealed because of adverse weather conditions (activity on the background plots will also be low).
Keywords: disturbed soil, trunk oil pipelines, the fertile layer, diagnostic parameters, the degree of degradation, soil profile, humus.

Moisture supply and yield level of grain crops in Pre-baikal forest-steppe
N.N. Dmitriev
Summary. The evaluation of dependence is given between the volume of grain crops yield and the conditions of moistening in production and long-time stationary five-fields crop rotation. It has been stated that the value of grain crops yield is determined not by a total amount of precipitation for vegetation period, but by a mode of their distribution among vegetation periods. High positive correlation dependence is marked between the yield value of spring wheat and total precipitation in May (+0,41-0,70). As for barley, such dependence was not observed in the variant without fertilizers, because barley was sown on a grain predecessor, and the limiting factor was the lack of mineral nitrogen in soil (-0,16). Fall precipitation of previous year did not make any positive effect on the yield value during the process of seeding in the fourth five-days period of May, which was due to moisture loss as a result of intensive evaporation in spring.
Keywords: spring wheat, spring barley, fertilizers, moisture supply, yielding capacity.

V.V. Petrenko
Summary. From all volume of wheat food grain annually not less than 75 % goes for processing to the flour. Modern lines in the food-processing industry, the population formed under the influence of increasing consumer ability, on the food stuffs made exclusively from natural ingredients, orient generators on search of ecologically safe food materials which are not demanding updating of the properties different additives. Studying of physical properties and a trial laboratory batch made as a final, most important evaluation stage of processing behaviour of the flour. Grain that was grown at biological system of agriculture the maintenance of gluten 26-29 % were up to standard that on 2 - 4 % more low in comparison with intensive, but it surpassed it in quality (80-97,5 units IDG). An index of force of the flour (301-310 е.а.) and elasticity of the paste (89-91 mm) throughout the first 6 months of grain storage received at biological system of agriculture fell into satisfactory improver. At carrying out of trial laboratory batches good results on a volume yield of bread (430-490 sm3) and its porosity (to 74 %) have been received stable. The general baking assessment was above centre 3,9-4,1 points. Studying of changes alveograph indexes and baking qualities of flour from the grain that was grown without use of mineral fertilizers and pesticides, in comparison with the standard intensive system of agriculture, has shown that such flour is quite applicable for reception of qualitative bread.

Summary. Seven columnar apple cultivars developed at the VNIISPK and three control cultivars are briefly characterized from the commercial and biological points of view. Under the artificial freezing it was stated that «Girlyanda", "Yesenia" and "Sozvezdiye" were characterized according to the highest level of bud hardiness in January under -40°C (component II) and also according to all components of winter hardiness. All the rest cultivars had an average level of winter hardiness on the level of control cultivars "Valuta" and "Moskovskoye ozherelye". Early fruit-bearing and productivity of the new columnar cultivars and their biometric parameters when growing on semi-dwarf rootstock 62-396 at common schemes of tree planting, lm x 0,5m are shown. Thus, 'Yesenia' is the most early fruiting cultivar; 65,4% trees started fruiting in the third year after the inoculation. The comparative study of columnar cultivars cultivating in a crown of winter-hardy semi-dwarf rootstock 3-4-98 and on intermediate stock 3-4-98 is given. This study has shown that trees of columnar cultivars are more productive and early fruiting when they are on 3-4-98 skeleton than on the intermediate stock. 6,6 times as many trees c."Zelyony Shum" started fruiting on 3-4-98 skeleton than on intermediate stock. In c. "Poezia" 1,4 times as many trees started fruiting on the skeleton. The productivity of both cultivars on the skeleton is four times as much than on the intermediate stock. The display of growing and production traits of columnar cultivars have been studied when cultivating them in a crown of rootstock 3-4-98 with different planting density: 3 x 2m, 3 x 1,5m and 3 x 1,0m, respectively. It is shown that the highest yield of top-quality fruit can be reached from the area unit when skeleton-forming trees are planted according to scheme 3 x lm. With planting density 3m x lm, productivity of c. "Poezia" was 172,9 metric centner/ha, c. "Priokskoye" - 187,5 metric centner/ha, c. "Vostorg" - 182,5 metric centner/ha, c. "Sozvezdiye" - 127,5 metric centner/ha, respectively. Data on fruit marketability and biochemical composition of columnar apple cultivars cultivated in a crown of rootstock 3-4-98 with different planting density are given.

A.A. Belyaev, M.V. Shternshis, T.V. Shpatova, V.I. Lutov, A.A. Leliak, A.I. Leliak
Summary. The influence of four bacterial formulations under total name Phytop on strawberry survival, growth, disease severity and fruiting was shown. Field testing was carried out in 2010-2012 in strawberry plantation of agricultural cooperative «Gardens of Siberia» (Novosibirsk region). Strawberry cultivar Junia Smides; leaf white spot caused by Ramularia tulasnei and fruit gray mold caused by Botrytis cinerea; formulations based on bacterial strains of Bacillus genus from culture collection of the firm «Research Center». All formulations Phytop 1.68, Phytop 3.69, Phytop 14.72 and Phytop 8.67 were developed and produced by this firm. Strawberry seedling roots were treated before planting by means of dipping in the formulation suspension contained 105CFU per см3. The treatment of plants by Phytop 3.69 enhanced 14, 3 % more survival rate of seedlings of strawberries compared with untreated plants. The treatment of plants by Phytop 1.68 and Phytop 14.72 caused root mass increase to 25-26 % compared with control. We observed the increasing total plant mass (41-52 %), root length (13-17 %), length of plant parts above the ground (3-5 cm) and the number of forming leaves and stolons under the treatment by Phytop 1.68, Phytop 8.67 and Phytop 14.72 compared with untreated plants. It was proven that the disease severity caused by Ramularia tulasnei reduced by 1.5-1.7 times and the disease severity caused by Botrytis cinerea reduced by 2.5-3.0 times under the treatment by all formulations. This fact could be explained with the formation of higher level of nonspecific resistance for strawberry plants due to the treatment of roots by bacterial formulations. The yield of untreated plants was 4.66 ton per hectare and the yield of plants treated by Phytop 1.68, Phytop 14.72 and Phytop 8.67 exceeded this value to 15-28 %. Profitability level of treatment was 160.2-377.1 %, profitability level of production was 82.7-96.5 % (compared with control profitability of 68.4 %). The application of formulations named Phytops is promising to expand the possibilities of ecologically safe managing plant adaptation, growth and disease at early stages of strawberry plantation.

Summary. The study was conducted to test the effect of bacterial strains Bacillus genus on infestation of blackcurrant with fungi causing leaf spot and fruiting in field. Field testing was carried out in 2010-2012 in black currant planting of agricultural cooperative «Gardens of Siberia» (Novosibirsk region). Black currant cultivar Sophia, anthracnose and white spot currant diseases, formulations based on bacterial strains of Bacillus genus from culture collection of the firm «Research Center». All formulations Phytop 1.68, Phytop 3.69, Phytop 14.72 and Phytop 8.67. Plants were treated once at the first symptoms of the disease by spraying ground mechanized working suspension at a concentration of 104 CFU/см3. Treatment reduced the growth of anthracnose and septoria lesions by 2,0-2,8 times within 10-14 days after application of suspensions. The achieved differences between the tested and control options in the leaf damage mostly remained until the end of the growing season. Biological efficiency of Phytop 3.69, Phytop 14.72 and Phytop 8.67 in reducing infestation of black currant leaf spot was 60,2-64,6 %. Plant treatment with Phytop 3.69 and Phytop 14.72 increased the number of blossoms and berry brushes pert one bush compared with control lacking the treatment. Overall productivity and blackcurrant yield obtained by biological disease control exceeded yield of 3.38 tons per hectare in control lacking the treatment by 0,65-0,67 tons per hectare (19-20 %). The level of profitability of treatment was 176,6-185,1 %, the profitability of production was 55,9-56,7 % (with 43.8 % in control lacking the treatment). The use of the formulations formulations Phytop 1.68, Phytop 3.69, Phytop 14.72 and Phytop 8.67 is promising in the improvement of environmentally safety technology of black currant cultivation and possibilities for leaf spot biocontrol.

A.S. Durov, N.G. Gamarnik, V.S. Deeva
Summary. Breeding lines of Simmental cows raised at the NIVA Co Ltd multiplication farm of Tashtypskiy District, Republic of Khakassia, were evaluated. Production and exterior characters of the animals were used for studying. According to results of the evaluation, full-grown cows meet the Simmental breed standard in live weight by 91%, milk yield by 94%, butterfat content by 98%. An animal unit of the Celota 16040 breeding line has the following parameters: 546 kg live weight, 3833 kg milk yield, 3.86% mass butterfat share, 2.98% mass milk protein share, 147 kg butterfat, and 114 kg protein, on the average. A number of significant differences between cows of different breeding lines in production and exterior characters were observed. The daughters of bulls belonging to the Patenta 2468 breeding line exceed their contemporaries in width of the chest behind shoulders (43.20 ± 0.56 cm), Reflection Soveringa 198998 in oblique body length (194.88 ± 1.22 cm). Cows of the Neolita 8593 and Etap 967 breeding lines are significantly inferior to their contemporaries in butterfat and protein production. The maximum milk yield index was observed in the Celota 16040 cows (705 kg), the minimum in the Etap 967 cows (589 kg) (P>0.95). Resulting from the evaluation, it should be noted that Simmental cows of the Patenta 2468 and Celota 16040 breeding lines have rather high milk production performance (3728.90 ± 118.50 kg and 3833.27 ± 115.0 kg, respectively). Therefore, the animals of these breeding lines should be used for forming the kernel of breeding stock provided they meet the breed standards. Sires of these lines should be used in herds of Khakassia on a broader basis. For the Neolita 8593 and Etap 967, it is necessary to choose effective successors.
