Abstract The effects of different doses of irradiation, including gamma and electron irradiation, on viability of saw-toothed grain beetles (Oryzaephilus surinamensis) have been studied. Barley grains infested with the pests were irradiated with a GUR-120 unit in a dose range of 150–1000 Gray (Gy) (treatment at doses of 100–120 Gy/h and 1800–2000 Gy/h) and with a “Duet” electron accelerator in a dose

Abstract The objective of the survey is to reveal the effects of a dysfunctional relationship between the gonadal steroids (progesterone and 17β-estradiol) on occurrence of inflammatory diseases (endometriosis and metritis-mastitis-agalactia) in sows in the postpartum period. The surveys were carried out with 27 sows at 106–107 days of gestation, measuring the concentrations of progesterone and 17β-estradiol

Abstract The wool and meat production of Khangil-type fine-fleece sheep within the Trans-Baikal breed has been studied. It is ascertained that 33.5, 59.1, and 7.4% of sheep are assigned to elite, first class, and second class, respectively, according to the rank structure. Liveweights of fine-fleece rams, replacement rams, ewes, and ewe lambs of the Khangil type exceed the breed standard for liveweight

Abstract The effect of short-term salt stress induced by carbonate salinization on the indicators of oxidative stress, the activity of antioxidant enzymes, and the content of some metabolites in winter triticale seedlings were studied. The experiment was carried out on 7-day-old plants after 12, 24, 48, 72, and 96 h of exposure to 120 mM sodium carbonate solution. The content of malonic dialdehyde

Abstract The effect of long-term usage of various fertilization systems (organic, mineral, and organic-mineral) on the agrochemical indicators of sod-podzolic heavy loamy soil and the productivity of crops of eight-field crop rotation has been studied. Fertilization systems with high saturation (manure 20 t/ha per year, NPK in equivalents of manure 20 t/ha per year, and manure 10 t/ha per year + NPK

Abstract Time dependences of projective coatings for different ecotopes of soil-plant communities on pastures in arid zones are obtained by numerical dynamic modeling in the form of ordinary differential equations. The models are developed for the dynamics of the functioning of four types of phytocenoses with different interaction schemes. The variety of schemes of succession transitions is caused

Abstract The objective of the surveys was to study fertility and productive performance of heifers and cows of the Red Steppe breed under different atmospheric pressure gradients of 725–750, 751–775, 774 mm Hg, and higher pressure gradients. On the days with the indicated atmospheric gradient frontiers, the heifer and cow insemination and milk yield control procedures with the analysis of the milk

Abstract The objective of the survey was to assess evolutionary trends in the mountain-grassland soil processes and the environmental and anthropogenic impacts on soil degradation and land efficiency. Generalization of the previously studied materials in comparison with the data collected in route surveys carried out in the large river basins, including the Samur, Chirakhchai, Sulak, and other rivers

Abstract The platelet activity in newborn calves of the Kholmogory breed was assessed. The studies were conducted on 39 animals obtained from healthy cows of 2–3 calving. Calves were examined five times in 2 days during the observation period. A tendency towards an increase in the activity of the aggregation process of blood platelets with all tested inducers was revealed during the neonatal phase

Abstract Present study carried out in a randomized complete block design with three replications for determining additive, dominance and cytoplasmic effects on inheritance of yield and some of agro-morphological traits in bread wheat. The highest value of grain yield (265.5 g m–1) was obtained in p6. Dominance variance was larger than additive variance for grain-filling period (GFP), plant height (PH)

Abstract The purpose of this research was to study the groat-forming ability of different varieties of winter rye and determine the specific varietal traits that positively influence the groat output. Fourteen varieties of winter rye differing in a number of morphobiological and technological grain properties served as the object of study. The varieties were grown on the fields of the Nemchinovka Research

Abstract This paper studies some parameters of animals’ immune status in case of combination and traditional therapy. The positive dynamics of circulating immune complexes (CICs) in the blood flow and restoration of the composition of white blood cells after combination therapy of sheep with spontaneous invasion with gastrointestinal strongylata were revealed. Preliminary subcutaneous double injections

Abstract The biological and economic efficiency of the use of the new, combined herbicide Uniko, CSC, (100 g/L fluroxypyr + 2.5 g/L florasulam) at application rates of 1.0, 1.25, 1.5, and 1.75 L/ha is studied in field trials. Cereal crops were sprayed in three stages: tillering/early booting, flag leaf stage, and heading (the experiment using herbicides at the latest stage was performed in Russia for

Abstract The biochemical features that govern multi-functions of boiling soluble proteins are still not well documented. This study reports isolation and sequencing of a water stress responsive cDNA which encodes dehydrin-like boiling soluble proteins (designated as TaBsSRP1 and TaBsSRP2: Triticum aestivum boiling soluble stress responsive proteins) from seedlings exposed to water stress from wheat

Abstract The studies were conducted on gray forest soils of OOO Agriko-Eurasia of Voskresensky raion (Moscow oblast) in 2015–2017 in order to substantiate the adaptive industrial (Dutch) technology of potato cultivation depending on the fertilizers and varietal characteristics. The study of the growth processes of potatoes showed that, when applying industrial technology, the development phases came

Abstract The recommended dietary intakes for the chelated metal proteinates containing copper in various bound forms, organic and inorganic, at different levels have been proven in an experiment with young fattening pigs. Compound feed enriched with copper sulfate at the rate of 40 g per t was fed to the tested animals in the control group. The animals in the first experimental group received compound

Abstract The purpose of this study was to substantiate the directions of reducing the damage to seeds during harvesting of grain crops. Threshing-separating devices of combine harvesters, physicomechanical characteristics of plants using wheat as an example, and parameters and modes of threshing devices that reduce grain damage were studied. It was revealed that grain damage is a consequence of the
