PRODUCTS OF PROCESSING OF RAPESEED IN FEEDING OF FARM ANIMALS AND POULTRY

abstract 1171603016 issue 117 pp. 284 – 304 31.03.2016 ru 349
In the current economic conditions of the import substitution, special importance is given to the search for new feed sources, methods of preparing them for feeding, the use of biologically active substances and enzymes. At the forefront of feed production is rape as breeding work with this culture has showed positive results. Currently, selectionists have bred yellow double-zero "00" varieties of rapeseeds free of erucic acid of "Canole" type, that have low glucosinolate level. The development of new and modern technology standards are required for preparation them for feeding, since they are fundamentally different from the previously used rapeseed varieties and have fewer restrictions for feeding to different types of farm animals and poultry. The article presents a fairly lengthy and reasoned review of the literature of a large number of authors on the topic, as well as given rapeseed market analysis, rational and advanced methods of preparing rapeseed processed products for feeding to young and adult animals. Much attention is paid to the use of a variety of biologically active substances and enzymes, which improve digestion and absorption of nutrients from rations with rapeseed processingproducts, increase productivity and reduce feed costs per unit of production. The use of processing products of rapeseed improves the profitability of livestock production. Feeding of rapeseedcake to cattle increases the protein content and volatile fatty acids in the rumen content, increases the number of infusoria and decreases ammonia levels. The inclusion of rape forage in diets of farm animals and poultry improves hematological parameters. Products of rapeseed processing of the varieties with low glucosinolatesa1re recommended for the rations of farm animals and poultry depending on the species, age and physiological state

ANALYSIS OF RESPONSE OF THE YIELD DEPENDING ON THE DURATION OF VEGETATIVE PERIOD OF WINTER BARLEY VARIETIES

abstract 1321708074 issue 132 pp. 951 – 964 31.10.2017 ru 352
Duration of vegetation period is one of the main adaptive traits for any crop or variety. Reasonability of cultivation of a variety in a particular soil and climate zone is determined by the duration of the vegetative period. One of the aims of breeding is the creation of the varieties with the main vegetative phases lasting at more favorable climatic conditions. The most accurate way to determine maturity group of a variety is by estimation of starting of heading phase, which can be defined with the greatest precision. The article covers the analysis of the duration of the vegetative period of the lines and varieties of winter barley of local and foreign selection in the central zone of Krasnodar region. All the varieties were divided into three maturity groups. The vegetative periods of the varieties were studied during four years. The most favorable and adverse conditions for yield formation were determined. The interactions between the productivity of the varieties depending on maturity group were identified. The varieties of the early maturity group which are more productive than the check were selected, which is most valuable for the breeding of the crop. The best varieties with the high and stable yield and the positive traits are regularly involved in the breeding programs with the porpoise of making new varieties of the winter barley

DEPENDANCE OF YIELD AND GRAIN QUALITY OF THE WINTER WHEAT FROM CULTIVATION TECHNOLOGIES IN LEACHED BLACK SOIL UNDER THE CONDITIONS OF THE WESTERN PRE-CAUCASIAN REGION

abstract 1321708117 issue 132 pp. 1425 – 1442 31.10.2017 ru 357
Elements of the cultivation technology of winter wheat variety called ‘Antonina’ with the application of different backgrounds of soil fertility, norms of fertilizers, system of plant protection from weeds, pests and diseases were studied. The studies are conducted in a polyfactorial stationary experiment: factor A - soil fertility; factor B - system of fertilizers; factor C - plant protection system; factor D - methods of basic soil cultivation. In the experiment four models of soil fertility levels were studied: А0 - the initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of litter manure); А2 - increased (doses are doubled); when А3 - high (tripled). Based on the studies it has been established that to obtain a stable yield of winter wheat, an increased dose of mineral fertilizers should be used, which also ensures high grain quality indicators. The maximum yield increase of 37% was achieved on varieties in comparison with extensive technology. A significant increase of the protein content in the grain from 12.8 to 15.3% and gluten from 22.0 to 27.8% was found in the intensive technology - triple doses of fertilizers (NPK) and the use of integrated protection against diseases, pests and weeds. The introduction of high doses of mineral fertilizers contributes to the accumulation in the soil and grain of nitrogen, and also reduces the content of copper and zinc

DYNAMICS OF CATALASE ACTIVITY IN THE LEAVES OF APPLE TREES UNDER THE INFLUENCE OF FOLIAR FERTILIZING

abstract 1271703067 issue 127 pp. 940 – 955 31.03.2017 ru 362
The research was conducted studying the effect of various system of foliar fertigation on catalase activity in the apple orchard with drip irrigation in 2013-2014. The object of research were apple trees of Zhigulevskoye variety grafted on rootstock 62-396 in experimental intensive apple orchard of I.V. Michurin FSC which had been planted in 2007. During vegetation, the following indices were determined in apple tree leaves in dynamics: catalase activity by gasometrical method of M.I Lishkevich on the 3rd and 5 th day after treatments, the content of nitrogen (Kjeldahl method), phosphorus (KFK-3), potassium and calcium (Jenway PFP-7). Data were statistical processed according to the generally accepted methods described by B.A. Dospekhov. It has been established that foliar fertigation increased catalase activity on the 3 rd day after treatment, which then decreases to normal values. So, treatments acted as a stress factor. Correlation of catalase activity with nitrogen content in the leaves increased, and with calcium content decreased as the number of megafol mixed with calcium calbit treatments was enlarged. Using tank mixtures for multiple treatments with combination of antistress preparations and calcium-containing agrochemicals allows to moderate significantly the stress effect of foliar fertilizing on plants

abstract 1211607142 issue 121 pp. 2331 – 2368 30.09.2016 ru 363
A fundamental element of the technology is the use of beef cattle in the economic purposes of biological resources of animals. In the development of modern technologies there is a lack of focusing on one of the main features of cattle – its own perception of the environment, that is panoramic (binocular) vision. In the modern cattle breeding we focuse on the development of a variety of exterior signs. However, one of the indicators that affect the behavioral responses of animals (the degree of development of the muzzle and the forehead of the animal, the shape of the head) does not have due importance. The author has conducted its degree of development studies in bulls and cows of different breeds. Along the length of the head, meat breeds (Hereford, Aberdeen Angus, Simmental, Charolais) gave way to Red Steppe 14.9; 15.5; 5.5 and 5.0 cm (27,5; 28,6; 10,1 and 9,2%, P

LANDSCAPE FEATURES OF EXISTENCE OF SOIL EROSION ON AGRICULTURAL LANDS IN THE BRYANSK REGION IN THE TRANSFORMATION OF CLIMATE

abstract 1171603030 issue 117 pp. 490 – 499 31.03.2016 ru 366
The article has considered the influence of modern climate changes on the intensity of erosion processes within the boundaries of the basic landscapes of the region. It has given the results of the spatial distribution of the rainfalls. The most noticeable climate changes of the Bryansk region are reflected in the decrease in the activity of erosion during snowmelt due to the lower amounts of snow and soil frost depth. In the area, the dynamics of rainfall does not detect a single trend. The processes of erosion and deflation are studied in the relationship, the manifestation of these processes on the territory of the Bryansk region. It has published the results of the risk analysis of erosion and deflation on forest soils of the region and justified the application of G. V. Bastrakov’s method for modeling erosion-resistant agricultural landscapes. This approach has a number of advantages over the other known methods. In our case, regardless of soil and climatic and geomorphological conditions, the challenge is to ensure such events in which erosion resistance of the land will not be below a critical value. The research results are the initial data in designing soil conservation activities on the territory of the Bryansk region. The obtained data of the erosive properties of soils from climatic changes enable the study and forecasting of the development of agricultural landscapes of the region in the medium term

abstract 1301706090 issue 130 pp. 1236 – 1248 30.06.2017 ru 366
The article reviews the results of studying the influence of mineral fertilizers on the qualitative indices of the Merlot grape variety in the Anapo-Taman zone of the Krasnodar region. The technology of cultivation of grapes on the experimental plot was in accordance with the accepted for the given zone and culture. Agrobiological work was carried out at the optimal time and had a high quality of execution. Grape bushes are laid in a 3.0 x 2.0 m pattern. Formation - a twoshoulder horizontal cordon. On the bushes we formed the same load of shoots and bunches. Scheme of the experiment: option 1 – no fertilizers (control); option 2-superphosphate with a mixture of potassium salt (P90K90) from the autumn; option 3 –nitroammofoska (N120P120K120) from autumn; option 4 – ammonium nitrate (N60) in early spring. Analysis of the results of studies on the study of biological features of growth, fruiting, yield and quality of Merlot grape varieties on the background of the use of mineral fertilizers shows their high efficiency in the conditions of the AnapoTamanskaya zone of the Krasnodar region and can be recommended for use in production conditions. Mineral fertilizers ensures the receipt of dry bulk wine of superior quality control sample (without fertilizers) the concentration of tartaric acid 17.3 25.1 percent, phenolic compounds 17.1 – 40.0 %, and alcohol content of 7.2 and 9.3 %, titratable acids 11.8 and 13.7 %, given extract by 17.4 %, with a decrease of the mass concentration of total sulfur dioxide and pH. The most effective is the introduction of NPK (N120P120K120)
