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 281
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 1221608025 issue 122 pp. 347 – 356 31.10.2016 ru 282
This article presents results of trials of feed additives called "Yoddar-Zn" and "Glimalask-Vet" to improve quality characteristic of meat of beef cattle. It was established that the most efficiency of these additives was achieved when used in complex. The carcasses of calves, which were consuming a complex of additives "Yoddar-Zn” and “Glimalask-Vet” (I c.), contained meat of the highest sort more than control by 6.48 kg, the animals which consumed only "Yoddar-Zn” (II c.) - 3.50 kg, the first-sort - at 15.19 and 7.86 kg. In experimental groups of calves there were observed more intense integral characteristics of meat color. The flesh of carcasses from the calves of experimental groups, the fat was higher than control, 0.13 and 0.07%, protein - by 1.79 and 0.97%. Animals experimental groups synthesized more protein at 5.45 kg, or 13.70%, and 2.62 kg, or 6.59%, energy - to 304.3 MJ, or 18.17%, and 146.8 MJ, or 8.77%. Meat of experimental animals, contained more essential amino acids. Protein meat quality indicator was higher than control, 0.73 and 0.28, amino acid index - by 0.17 and 0.04. The meat from calves of experimental group had a higher culinary and technological parameters, optimal fractional composition of muscle protein and lipid composition of adipose tissue, better digestibility

BIOLOGICAL EFFICIENCY OF FUNGICIDES IN WINTER WHEAT CROPS AND THEIR INFLUENCE ON CROP YIELD

abstract 1321708080 issue 132 pp. 1035 – 1044 31.10.2017 ru 282
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

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 283
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

abstract 1341710088 issue 134 pp. 1083 – 1095 29.12.2017 ru 285
In the soils of rice fields, eluvial gley processes develop, which are manifested in redistribution of silty particles along the profile, water-soluble humus, mobile compounds of iron and phosphorus. Most intensively, these processes are developed in meadowbog soils, confined to closed depressions of the plains plain. Meadow-black soils lying on elevated relief elements have more favorable physical, physicochemical and oxidation-reduction properties for cultivating rice and accompanying crops in crop rotation. The highest yield of rice is formed on high checks and higher at 12,4 c/ha than on low ones

abstract 1311707132 issue 131 pp. 1612 – 1626 29.09.2017 ru 286
The influence of different agricultural technologies on the yield of winter barley variety ‘Gordei’ was studied. Economic evaluation was given to the researched factors. The studies were carried out at the experimental station of Kuban State Agrarian University in the conditions of polyfactorial long-term soil monitoring. The soil is represented by strongly leached, light-clay black humus with an average thickness of the humus horizon - 150 cm. It was found that with the change of technology (fertilizer, tillage, sowing method, means of protection) winter barley yields increases to 50% in comparison with the control. According to the analysis of bioenergetic and economic evaluation it makes sense to use the variants 022, 111 and 222 at plowing, where the maximum net efficiency ratio and net income are noticed

abstract 1341710071 issue 134 pp. 884 – 894 29.12.2017 ru 291
The study of the productive qualities of crossbred offspring from different breeding combinations and identifying the most effective ones providing the maximum increase in the production of high quality lamb while reducing its cost is an important problem and is essential for further development of methods of creating a new type of precocious meat and wool sheep. In the Rostov region in the result of the establishment of populations of meat-wool sheep there are several groups of animals with different characteristics and hereditary inclinations. As the base of the work there is a method of mating and breeding of sheep of the desired type. The article presents the results of one of the fragments of a large complex work in which the possibility of using three-pedigree hybrids, created with the involvement of potential salskaya, edilbaevskaya and intense meat-wool breed, which is severokavkazskaya, to improve productive quality in the breeding of sheep. We have evaluated productivity and biological features of hybrids and proved the economic efficiency of their use in the production of mutton. We have given the results of the control slaughter and assessment of qualitative indicators of the meat of young sheep. The set of indicators characterizing meat productivity and meat quality revealed that the superiority of the studied indicators remained for two - and three-bred cross cattle. Hybrids have a higher rate of growth and quality parameters of meat productivity. These options are simple and complex industrial crossing are promising and can be implemented and used on the farms of the zone of breeding Merino sheep. Thus, the use of crossbreeding gives an opportunity to convert a flock of sheep in the desired direction quickly. At the same time, three-pedigree hybrids better combine the valuable qualities of the used species

CHEMICAL COMPOSITION COMPARISON OF DRIED TOBACCOS OBTAINED FROM DIFFERENT HYBRIDS, SORTS AND LINES

abstract 1281704068 issue 128 pp. 1003 – 1013 28.04.2017 ru 292
Tasting and smoking properties of tobacco products depend on chemical composition of dried tobacco. The most important are nicotine, carbohydrates, and proteins. Their content is controlled when new sorts are bred. In the article data on chemical composition and their analysis for some hybrids, new and zoned sorts are presented. Most of studied samples had medium nicotine content in dried tobacco. Hybrid of Jubileiniy noviy 142 and Ostrolist 46, sorts: Trapezond 159, 359, 115 and Ostrolist 46 were characterized as low nicotine tobaccos. Jubileiniy (standard) and Oktiabrskii were characterized as high nicotine tobaccos. This indicator depends on rain quantity during vegetation period. During drought seasons this indicator is higher. Total soluble carbohydrates content affects smoke taste. The more water soluble carbohydrates content the better smoking properties tobacco has. Unlike nicotine, carbohydrates content when rainy season increases. Best results were for Krupnolistniy 9M and Oktiabrskii. Proteins have negative effect on smoke taste as it becomes bitter and with smell of burned feathers. Most of studied hybrids have quite high protein content. For cured tobacco quality assessment, not total contents of proteins and carbohydrates are important but their ratio (carbohydrates/proteins) called Shmuk ratio. Best results were for Krupnolistniy 9M and Oktiabrskii

CENTURY-OLD SIBERIAN STONE PINE CROPS GROWTH AND PRODUCTIVITY IN THE ZONE OF CONIFEROUS-BROADLEAVED FORESTS OF THE MIDDLE VOLGA REGION

abstract 1311707097 issue 131 pp. 1168 – 1180 29.09.2017 ru 294
The purpose of the study was to examine a century of experience of growing of forest cultures of the Siberian stone pine in forest conditions in the region of the Middle Volga. To achieve these objectives, we have investigated old growth culture of Siberian stone pine in the conditions of fresh oak forests in the territory of Rootka forestry of the Mari El Republic. Culture of Siberian stone pine was planted after continuous tillage. The distance between rows was 2,5 m, step landing – 1,0 m. The site was divided into five options, depending on variations in the width of planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m, V - 32 m). The studies have shown that the Siberian stone pine trees, regardless of the variant, are characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It can be noted that in the 100-year-old age, the average height of trees reaches of 28,7 m, an average diameter of 49,8 cm. Stock of forest reaches 795,3 m3 /ha. Best annual increase is observed in growing cultures of cedar in the wings with a width of 40 m and is 7,95-of 7,93 m3 /ha. Based оn the research, we have concluded that Siberian stone pine should be recommended for introduction into the zone of coniferous-broadleaved forests of the Middle Volga region. When creating crops, it is necessary to use larger seedlings and plant density is not more than 1,0 thousand pieces/ha, and the width of the planting strip shall be not less than 40,0 m.
