The agroclimatic resources of the Astrakhan region are quite large and represent huge opportunities in the production of heat-loving crops such as vegetables and melons. The region has accumulated a great scientific and production experience in the cultivation of tomatoes as the main vegetable crop rotation crop. To date, the first task for farmers of the region is to develop new modern agrotechnological techniques to eliminate the spread of thrips on open-ground tomato plants. The object of research was a hybrid of tomato of the domestic selection of the agricultural company Sedek Azhur F1. Materials and methods. For the first time, for the conditions of light chestnut soils on the land use territory of FSBNU “Caspian Agrarian Scientific Federal Scientific Center of the Russian Academy of Sciences” during 20182020. the influence of various insecticides in the fight against tripasmi was studied. As a result of the analysis, the presented scientific article presents the main results for the study of new modern insecticides in the fight against trypses on open-ground tomato Azhur F1. According to the results of three years of study, the optimal option with the use of the drug Confidor Extra was revealed, which contributes to a significant decrease in the number of phytophages. The use of these preparations had no phytotoxic effect on open-ground tomato plants. In the version using the insecticide Confidor Extra, there was more purely commercial fruits and a significant increase in the crop relative to control without treatments, as well as a variant where the Fufanon-Nova preparation was used. The increase relative to control in the high-yield version was + 40.8 t/ha or 43.5%.

Chrysanthemum is one of the leading crops of commercial floriculture. Within garden groups and classes, chrysanthemums are divided according to cultivation methods, shape and size of the inflorescences. For varieties grown on a cut, a group of large-flowered (with a diameter of inflorescences of 12-25 cm), small-flowered (4-10 cm) chrysanthemums and santini (from 2 to 4 cm) is distinguished. Having a limited assortment of chrysanthemum garden, in a humid subtropical climate, it is possible to form a largeflowered (single-headed, disbud) and small-flowered (spray) cut. The purpose of the research was to study the peculiarities of formation of large-flowered chrysanthemums (Chrysanthemum×hortorum Bailey) to obtain cut in the humid subtropics of Russia. The objects of research were large-flowered and small-flowered varieties of chrysanthemums of foreign and domestic breeding. The studies were carried out in the open ground of the Department of Agricultural Engineering and Nursery of the Federal Research Center the Subtropical Scientific Center of the Russian Academy of Sciences. Scientific research was carried out according to the methodology of State variety testing of agricultural crops and the methodology of testing for distinctness, uniformity and stability of chrysanthemum (perennial) Chrysanthemum spec. ‘Sevan’, ‘Baltica White’, ‘Granada’ and ‘Zembla Brasil’ are large-flowered varieties, which have bush peduncles of good commercial quality with large inflorescences of saturated shades. In turn, from small-flowered garden forms ‘Zembla White’, ‘Annecy White’ and ‘Westland Regal’ with regular pinching, you can grow a large-flowered cut of chrysanthemums. It was revealed the relationship between biometric characteristics in order to determine additional diagnostic features of the possibility of the formation of large-flowered inflorescences. So, the diameter of the inflorescence is the most significant parameter for research which has significant positive relationships with the diameter of the peduncle and the length of the extreme ray flower. It will allow determining the possibility of growing the variety in one form or another, depending on the needs of production, at the initial stages of introduction and variety study.


Intermittent Lighting Improves the Efficiency of Artificial Insemination in Cage Housed Laying Hens Kavtarashvili A.Sh., Kolokolnikova T.N. Federal Scientific Center “All-Russian Research and Technological Poultry Institute” of Russian Academy of Sciences Omsk Agrarian Scientific Center Summary: The effects of different lighting regimes on the oviposition schedule, productive performance, and reproductive efficiency in cage housed laying hens of layer parental flock (Hisex White-R) were studied; the reasonable regime of artificial insemination (AI) under intermittent lighting is proposed. It was found that intermittent lighting regime 1L:4D:4L:1D:4L:10D compared to the constant lighting significantly alters oviposition schedule: under this regime 82.3% of all daily eggs were laid until 9 am (vs. 66.6% in control). This regime and AI at 10 am improved the productive and reproductive performance compared to control (constant lighting 16L:8D and AI at 12 am): mortality by 1.9%, egg production per initial hen by 3.8%, egg weight by 1.1%, percentage of eggs suitable for incubation by 1.9%, egg fertility by 0.9%, hatchability by 2.3%, hatch of chicks by 2.9%, feed conversion ratio (kg of feed per 10 eggs) by 5.3%, the expenses of electric energy for lighting (per 1000 eggs suitable for incubation) by 54.5%.

The article studies the possibility to use glycerol as cryoprotectant, instead of dimethylsulfoxide for cryopreservation of sperm of inconnu ( Stenodus leucichthys Gueldenstaedtii, 1772). Investigations were carried out from 2015 to 2016 in the laboratory of the Southern Scientific Center, Russian Academy of Sciences, on the basis of the Astrakhan State Technical University. The material collected on the Alexander sturgeon hatcheries (the Astrakhan region) in the spawning period. Native sperm of 6 male inconnu species was used as a control means. The semen quality was determined in terms of moving activity (life time) of sperm after its activation by water. As the cryoprotectant there were used: base solution - 80%, sucrose - 1.71 g/l, mannite - 0.98 g/l, yolk - 10%, dimethylsulfoxide - 10% and base solution - 87%, sucrose - 1.71% g/l, mannite - 0.98 g/l, yolk - 10%, glycerol - 3 variants: 3; 5 and 10%. In order to provide the most complete penetration of cryoprotectants into the cells there were used electrostimulation of cell membranes. Equilibration time was 5 and 15 minutes. Thawing semen was performed in a water bath at a temperature of 38-40°C. For removing protectors from cells there was chosen a saline solution (0.7% NaCl) as isotonic solution. In tests using dimethylsulfoxide life activity of sex cells was 2 times lower than in tests with glycerol: 78 and 186.2 s at the end of equilibration and 52.3 and 128.9 s after thawing. Sperm showed maximum activity under 5% glycerol concentration during equilibration - 15 min. Concentration of 3% was insufficient, concentration of 10% was excessive, as it suppressed activity of sperm. Egg yolk which coagulated together with glycerol, making difficulty for observing, had to be excluded from the composition of cryoprotectant.

The article presents the results of the analysis of the biochemical composition of selected in the competitive variety testing of new varieties and promising lines of spring barley, studied on the experimental field ISA-branch of FGBNU FNAC VIM in 2016-2018. Result of research in different years of water availability among the rooms was allocated a group of high-protein barley with improved feed value: 4 varieties, 2 of which are on the state variety testing, and 2 promising lines. The range of variation of protein content in the grain of the selected samples varied from 13.1 to 14.5 %, lysine – from 0.48 to 0.52 %, weight of 1000 grains-from 48.0 to 53.5 g. According to the data obtained the highest value of protein in grain was observed in krupnosortnogo varieties Zlatoyar (GSI), amounting on average for 14.5 %. The increase was equal to 1.1% in relation to the control variety Yaromir. With an average yield of 6.52 t/ha in the years of research grade Accounting have provided protein per hectare in the amount of 0,94 t/ha. A new variety Sudar´ (GSI) and breeding line 149/4-12 h 788 and 129/1-14 h 907 this indicator has been less productive, however, exceeded the grade Yaromir 0.10 to 0.16 t/ha. Given the higher productivity of new promising varieties and breeding lines, the collection of lysine per unit area they have 12.7, 30.8 per cent was higher than that of the Promej class and 10.6-23.6% more than in the variety Yaromir, which indicates their high biological value. Selected hulless line 1137 h is also an encouraging source of protein and other nutrients of plant origin. The selected lines and new varieties, regardless of weather conditions, were able to ensure the production of high-protein and sources' grain for feed purposes, while maintaining productivity.
