AGROBIOLOGICAL EVALUATION OF NEW STRAWBERRY VARIETIES IN THE CONDITIONS OF THE PRIKUBANSKAYA ZONE OF GARDENING IN THE KRASNODAR REGION

abstract 1491905016 issue 149 pp. 81 – 91 31.05.2019 ru 74
The article presents the results of studies on the biological characteristics of growth and fruiting, as well as the yield of adaptive varieties of strawberries in the conditions of the Prikubanskaya horticulture zone of the Krasnodar region. The objects of study are new and promising varieties of strawberries: Zenga-zengana (k), Onda, San-Diaz. The experiments were performed using the method of randomized reps. In the experiment there are 3 options, in each there are three replications of 20 plants. Variants and repetitions are placed sequentially. Agricultural records of the growth and fruiting of strawberry plants were carried out according to generally accepted methods; statistical processing of research results was carried out using the analysis of a variance method described by B.A.Dospehov. The results of our research showed that Zenga-zengana bushes (control) turned out to be the tallest. In the Onda variety, the height of the bush is 2 cm less than in the control variety; and San Diez varieties are 4 cm, respectively. It should be noted that the most undersized plants require a smaller area of nutrition. It has been established that flowers pollinated a few days after their disclosure develop more rapidly into berries than those that were pollinated immediately after opening. Pollen in flowers of the first order is less than in flowers of the third or fourth order. The stamens of the first flowers are often underdeveloped, their pollen is released and germinates worse. In our experience, the average weight of fruits and the yield as a whole depends on the biological productivity of the varieties. Onda was the most fruitful variety, and the rest varieties were at the control level

BIOPOSITIVE METHODS OF PROTECTION AND RESTORATION OF ERODED AND DISTURBED AREAS OF AGRICULTURAL AND RECREATIONAL ZONES

abstract 1491905017 issue 149 pp. 92 – 101 31.05.2019 ru 75
The struggle against soil erosion and the restoration of disturbed lands is a pressing issue for the regions of the North Caucasus and southern Russia. This problem is also acute in Kabardino-Balkaria, where more than 30% of agricultural and coastal lands suffer from water, anthropogenic and man-made erosion. Existing methods need to be improved and adapted to natural and local conditions. The aim of the work was to develop more efficient methods for the accelerated recovery of eroded and disturbed areas of land with the use of biopositive products and fastenings from local materials. Several technological solutions have been developed for the protection and restoration of land plots of agricultural and recreational zones located on slopes and coastal zones that have been eroded and disturbed by economic activity. All of these technical solutions are investigated and brought to the level of inventions and utility models. According to the results of the research conducted for the mountain and foothill areas of eroded lands, new methods are proposed based on the use of environmental protection technologies and restoration of damaged land. The introduction of these methods increase the effectiveness of anti-erosion measures and reduce the material costs of their implementation

TECHNOLOGICAL ASSESSMENT OF VARIETIES AND HYBRIDS OF BEET-ROOT AS RAW MATERIALS FOR MANUFACTURING MASHED SEMI-FINISHED PRODUCTS

abstract 1491905021 issue 149 pp. 116 – 127 31.05.2019 ru 63
One of the promising ways of deep processing of beetroot is the production of sterilized mashed semi-finished product. The quality of the finished product is determined by a complex of factors, among which an important role is played by the varietal characteristics of the raw materials. Research on the technological evaluation of table beet varieties and hybrids for suitability to this method of processing was carried out in 2018 on the basis of the Department of Agriculture and Agrochemistry of the All-Russian Research Institute of of Vegetable Growing, a branch of the Federal State Scientific Center of the Russian Academy of Sciences and the Department of Fruit and Vegetable Storage and Processing Technologies Timiryazev. In the course of the research, the following tasks were solved: analysis of the raw materials for the main biochemical quality indicators (the content of dry substances, sugars, betanin, nitrates); laboratory production of sterilized puree semi-finished product and its evaluation by chemical composition and organoleptic characteristics. Based on the biochemical parameters of raw materials, the domestic varieties of single-seeded Russkaya odnosemyannaya (21.5%), Bordovaya VNIIO (20.1%) and Karina (19.8%) were distinguished according to the content of dry substances. According to the sugar content, varieties such as Karina (11.43%), Bordovaya VNIIO (11.19%) and Bordo 237 (11.03%) were distinguished. We have established a significant superiority of domestic varieties over foreign hybrids on the content of betaninand identified characteristic changes in the chemical composition of puree semi-finished product compared with the feedstock - a decrease in the content of dry substances, sugars, nitrates, a significant destruction of betanin. The highest scores on the complex of organoleptic indicators were obtained by samples of mashed semi-finished products made from beet varieties Smuglyanka, Bordo 237, Bordovaya VNIIO and Pablo F1 hybrid. - 21.6 ... 22.9 points on a 25-point scale. They should be recommended for industrial cultivation in the areas of procuring activity of canning enterprises engaged in the production of mashed semi-finished products

OPTIMIZATION OF THE RELATION OF BIOLOGICALLY ACTIVE SUBSTANCES AND PROBIOTIC MICROFLORA IN THE RECIPE OF COMPLEX FEED CONCENTRATE

abstract 1491905033 issue 149 pp. 149 – 157 31.05.2019 ru 88
Providing the population with basic food products, sources of proteins, fats, carbohydrates, vitamins and other essential nutrients is one of the main issues of ensuring the security of the country, while the requirement for food safety is paramount. Production of feed additives (concentrates), which improve feed conversion, while being natural and safe for animal health, acquires the greatest importance in the conditions of intensification of agriculture and increasing the competitiveness of livestock farms. Probiotic microflora, which, in competition with pathogenic, displaces the latter from the gastrointestinal tract, can be considered as one of the effective methods of controlling undesirable microflora in the digestive tract. In world science, research is actively conducted in the direction of searching for effective probiotic cultures. A promising way to increase the effectiveness of the use of probiotic feed additives is their addition to prebiotics, for example, including vitamins (antioxidants) and mineral substances (selenium). The purpose of this work was to determine the optimal ratio of biologically active substances contained in the feed vitamin-mineral concentrate, and probiotic microflora contained in the feed probiotic additive Bacell-M, for the development of complex feed concentrate. Using the Harrington's desirability function, the optimum ratio of biologically active substances and probiotic microflora in the recipe of the complex feed concentrate is determined, ensuring the maximum reduction in the serum levels of alanine aminotransferase in the blood serum of experimental animals, which characterizes the normalization of barrier organs

abstract 1491905035 issue 149 pp. 158 – 180 31.05.2019 ru 38
The problems of creating an optimal microclimate in the closed workshops of poultry farms are relevant for the regions of the south of Russia and the Northern Caucasus, especially acute these problems are for Kabardino-Balkaria. The used zoohygienic measures and existing ventilation systems of closed poultry houses need to be improved and adapted to the local natural conditions. The purpose of the work was to research and develop effective ventilation systems for closed poultry houses in hot climates. Existing ventilation systems and zoohygienic conditions in closed-type poultry houses were studied and investigated. According to the results, the main disadvantages of the existing ventilation systems and their low efficiency were established. And on their basis, new technical solutions have been found to create more efficient ventilation systems for closed poultry houses that provide the optimal microclimate: temperature, humidity and pressure. With the active participation of the author, new technical solutions have been developed and proposed, for which two applications for obtaining patents have been prepared: one for a utility model - for a device for moistening and cooling wall ventilation ducts of poultry houses; the second is for the invention - on the method of erecting a cooling system and humidifying the ventilation panels of the supply. During their implementation, these new technical solutions allow creating such a microclimate, thanks to which optimal indicators of productivity and growth, uniformity, efficiency of feed and meat gain are achieved, without reducing the characteristics of the health and well-being of birds. Ventilation is becoming a major factor in microclimate control in closed houses and the epizootological resistance of birds
