The article discusses the results of studying the effectiveness of using new generation herbicides: both applied before the emergence of corn seedlings ("Merlin" (150 g/ha); "Cassius" (50 g/ha)), and by seedlings ("Elumis" (1.0–2.0 l/ha)) – on crops of three maize hybrids. The studies were carried out in 2017–2019. The objects of research were maize hybrids of various early ripening (originator Kabardino-Balkaria Research Institute of Agriculture) – Kabardinskaya 3812 (late ripening), Camilla SV (mid-late), and white grain food corn Bella 451 (cultivated not only for obtaining varietal seeds, fodder, but also to meet the food needs of the indigenous population). Flour and cereals from white grain corn are used in most ethnic cuisines of the North Caucasus. In this regard, it is very important to put into production, along with the yellow grain forms used for fodder, highly productive varieties and hybrids of white grain corn for food purposes. The variety is medium late and food grade. The purpose of the research was to establish the level of harmfulness of weeds and their death rate at different periods of their introduction, as well as to determine their effect on the growth, development and yield of corn grain. The scientific novelty lies in the fact that in the conditions of the foothill zone of the Republic of North OssetiaAlania, studies have been carried out to establish the optimal terms and methods of applying herbicides in the fight against weeds when cultivating new highly productive corn hybrids. As a result of the studies, it was found that the treatment of the soil with the herbicide "Elumis" was more effective in comparison with the control option. At the same time, the grain yield was: for the Kabardinskaya 3812 hybrid 8.7 t/ha – on an unfertilized background, 12 t/ha – on a fertilized one; for the hybrid Camilla SV – 8.5 t/ha on an unfertilized background, 11.7 t/ha – on a fertilized one; the Bella 451 hybrid has 7.0 t/ha – on an unfertilized background, – 9.9 t/ha – on a fertilized one. The responsiveness of the Kabardinskaya 3812 hybrid to the application of herbicides was more effective than that of other studied hybrids.

Evaluation of new breeding samples of early ripening corn hybrids of All-Russian Research Institute was carried out on typical for the Republic of Tatarstan gray forest loamy soils. Unusual climatic conditions for the XXI century of the growing season of 2017 allowed us to make the most rigorous selection among the studied hybrids. At the time of harvesting a sample was detected with grain moisture 33.0 (control 34.6%), starch content in grain 58.8% (control 49.2%), grain productivity in terms of moisture 14.0% - 5.17 tons per hectare (control 4.73 tons per hectare). Also, two samples with grain moisture content of 38.4-38.7% were selected, which surpassed the control by 33.8-39.1%, with an equal starch content. The results of phenological observations of the growth and development of early maturing corn hybrids over 12 years were analyzed. A close negative correlation (r = -0.933) was established between the average daily air temperature and the duration of sprouting of the early ripe maize hybrids. A regression equation was derived, according to which a decrease in average daily air temperature by 1°C increases the duration of emergence of seedlings of early ripe maize hybrids in Tatarstan by 1 day.

The experience in cooperation of breeders of different institutions in creating cultivars is shown. It is not always when the breeding institution has the necessary initial forms for selection. In this regard, there is a need to conduct separate stages of selection in different breeding institutions. For this purpose, a provision on authorship and continuity in the integrated work of several institutions in fruit breeding has been developed (Program and methods of fruit, berry and nut crop breeding. Annex. – Orel, 1995. – pp. 492-498). Breeding work of the Russian Research Institute of Fruit Crop Breeding (VNIISPK) and North Caucasian Federal Scientific Center of Horticulture, Viticulture, Winemaking can serve as a positive experience of creating new apple cultivars by two institutions. As a result of the joint work of these two institutions, 22 apple cultivars have been created, of which 9 have already been included in the state register of breeding achievements approved for use (zoned), including three cultivars for the conditions of the Middle zone of Russia – Aleksandr Boiko, Maslovskoye and Yablochny Spas and six cultivars for the conditions of the North Caucasus – Vasilisa, Karmen, Margo, Orfey, Soyuz and Talisman. Brief economical and biological characteristics of these cultivars are given in this paper. The obtained practical results indicate that in some cases, when creating modern cultivars that meet the requirements of production, it is necessary to use the knowledge of breeders, the source material and equipment of different breeding institutions, and carry out separate stages of the selection process in different institutions.

The article examines the problems of open and latent ethnonational tension in Russian society, which in the conditions of aggravation of the social situation, may lead to the use of spontaneous methods of solving ethnonational conflicts, including those of a violent nature. A survey of 20 experts, who are qualified specialists in the sphere of ethno-extremism counteraction and ethno-national conflict localization, conducted by the author of the article, has shown that the majority of them have assessed both the current and forecasted situation in the sphere of ethnonational relations as “tense” for the next five to seven years. In their opinion, “ethnonational tension” is conditioned by a number of long-term factors that will influence the content and dynamics of ethnonational conflict in the Russian Federation: the desire of the USA for global dominance and the confrontational policy of NATO member states towards Russia; the antiRussian policy of the Ukrainian leadership, which is attempting to accuse Russia of “unleashing and waging a hybrid war against Ukraine” and actively pushing Western countries to strengthen confrontation with the Russian Federation; attempts by some states to bring territorial claims against Russia; intensification of the fight against embezzlement of budgetary funds, systemic corruption and ethno-extremist manifestations in the North Caucasus region; the ethnopolitical situation in the Republic of Crimea, characterized by manifestations of Ukrainian nationalism and militant Islamism. According to expert estimates, the highest degree of ethnonational tension is currently maintained in the Republic of Dagestan, the Republic of Ingushetia, the Kabardino-Balkarian Republic, the Karachayevo-Circassian Republic, the Republic of Crimea, the Republic of Bashkortostan and the Republic of Tatarstan. The results of research in the article testify to the necessity of constant study of the problem of ethnonational conflicts, research into the factors influencing the maintenance and dynamics of conflict potential, definition of Russian regions with an increased level of tension, development of recommendations to authorities on prevention and localization of ethnonational conflicts.

Birch forests from Betula litwinowii and Betula raddeana of the Northern macroslope of the Greater Caucasus with participation of Rhododendron caucasicum in the undergrowth are discussed in the article. The studies were carried out in 2017–2020 at the territory of Karachay-Cherkessia (Teberda State Natural Biosphere Reserve), Kabardino-Balkaria (Kabardino-Balkarian State High Mountain Reserve) and the Republic of Dagestan (Lak and Gunib districts, near the villages Burshi and Batsada). The characteristics of the growing conditions, analysis of the species and coenotic composition of communities are given. Birch forests with Rh. caucasicum are usually confined to the steep slopes of the northern exposure at the upper border of the forest belt, at an altitude of 1500–2800 m above sea level. The described communities can be divided into two groups depending on abundance and, consequently, influence Rh. caucasicum as an edificator. In the described communities there is a clear inverse correlation between the abundance of Rh. caucasicum with the projective cover of the grass-dwarf shrub layer. At the same time, the number of species in the grass-dwarf shrub layer doesn’t change significantly. The species composition of birch forests with the participation of Rh. caucasicum identified by us comprises 246 species of vascular plants. The herb-dwarf shrub layer is characterized by a relatively low species richness (on average, 26 species per sample plot). In these communities there are both characteristic forest species and representatives of subal-pine and, less often, alpine coenoses. Further study of communities of birch forests, which play sig-nificant water protection role, slope-holding and avalanche-barrier functions, is important for determining their current state, possible directions of changes, and assessing the need for protective measures in different regions.

The published documents were found in the archives of the Republic of North Ossetia-Alania. These are the materials of the meetings of the Soviet and party authorities of the Mountain Republic, which were devoted to the discussion of the problem of Kabarda's secession from the polyethnic mountain autonomy. The Kabardian problem was discussed several times by the leadership of the Mountain Republic in June 1921 before and after the congress of the peoples of Kabarda that took place this month. The minutes of the meetings have not yet been published in the published thematic collections of documents dedicated to the history of the nation-building of the peoples of the North Caucasus. The documents contribute to the understanding of the position of the statesmen of the Mountain Republic on the formation of new autonomous units and the identification of the concrete historical content of these processes. The protocols make it possible to reconstruct the process of not only the disintegration of the collective mountain statehood, but also make it possible to clarify important points in the history of its creation. Party and Soviet leaders often returned to the problems of the initial stage of the formation of the Mountain Republic. Further study of the problems of the formation of a system of national autonomies in the North Caucasus in recent times will largely depend, including on the introduction of new documents into scientific circulation and their interpretation by a wide range of researchers. In this regard, the published documents and materials are of great scientific interest.

The purpose of this article is to study the public opinion of residents of the North Caucasus region (on the example of the Republic of Dagestan) on the state of social and cultural adaptation and integration of foreign citizens. The relevance of the study is due to the fact that the growth of quantitative indicators of migration begins to significantly affect the ethno-social and ethno-political processes in the region and makes certain adjustments in the socio-political sphere of the republic. The main method of research is the quantitative method, i.e. a mass standardized questionnaire. The questionnaire survey was conducted taking into account the general socio-demographic characteristics of the population of the Republic of Dagestan. The content of the questionnaire is aimed at analyzing aspects of the ethnic identity of the Dagestani peoples, determining the ethno-cultural components of its reproduction, analyzing the attitude of the population of the Republic of Dagestan to the social and cultural adaptation and integration of migrants, and identifying the most effective ways to achieve this goal.

Abstract. The authors present the results of the use of herbicides on winter wheat crops in the steppe zone of North Ossetia-Alania. The purpose of the work is to study the effectiveness of the use of herbicides in winter wheat crops. The object of research is two varieties of winter wheat – Trio and Utrish, which differ in maturity, susceptibility to leaf-stem pathogens. The novelty lies in the fact that for the first time in the steppe zone of the Mozdok region, in the research and production department of the North Caucasus Research Institute of Mining and Piedmont Agriculture of the All-Russian Scientific Center of the Russian Academy of Sciences, the effectiveness of the use of herbicides in winter wheat crops was studied, an economic assessment of the studied agricultural techniques was given. Methods. The counts and observations were carried out according to generally accepted methods described in the “Educational-methodical guide for conducting research in agronomy”. Results. As a result of the use of herbicides and their tank mixture, it contributed to a significant reduction in the number of weeds (the percentage of death in the bumping phase varied between 55.9–81.1 % compared to the control). The removal of mineral nutrition elements by weeds was: nitrogen – 72.6 kg/ha, phosphorus – 14.4 kg/ha, potassium-52.4 kg/ha. Herbicides had a positive effect on photosynthetic activity. The leaf area during its maximum development (earing phase) according to the studied variants increased by 12.7–16.4 %, and the photosynthetic potential – by 13.7–17.8 %. The PPF for the studied options (the average value for the growing season) increased by 0.34–0.51 g/m2 per day. The studied drugs contributed to a significant increase in productivity. The largest increase was obtained according to the option: Grench (5 g/ha) + Luvaram (800 ml / ha) – 2.39–2.60 t/ha. The profitability level in the control (without herbicides) was at the level of 25.7 % (grade Trio), and according to the studied options ranged from 148.7 % (Luvarum 1600 ml / ha) to 169.2 % (Grench 5 g/ha + Luvaram 800 ml/ha).

Background. Paratypic variability of the development rates of barley accessions from the Republic of Dagestan was analyzed for five years in the Northwe st of Russia (Pushkin, St. Petersburg) and in the North Caucasus (Derbent, Dagestan). Responses to vernalization, photoperiodism and earliness per se were tested in contrasting environments to assess their effect on barley development. Such studies make it possible to identify valuable adaptable plant forms in the barley germplasm collection for further use in breeding practice.Materials and methods. In Dagestan, the duration of the period from shooting to heading was measured for 12 samples of barley accessions in winter and spring sowing trials. Twenty samples sown in spring in both regions were compared. An empirical indicator of plant development rate was used for barley: the criterion “the number of days by which the period from shooting to heading of an accession exceeds the minimum across a sample” (DPSH).Results and conclusions. Early barley accessions with a low norm of responsiveness were identified: k-3772, k-15013, k-15034, k-15036, k-15186, k-15192, k-21803 and k-23785 – they combined weak sensitivity to a short photoperiod and vernalizing temperatures, so they are promising for breeding in regions where the length of the growing season is a limiting factor. The effect of the responses of barley accessions from Dagestan to vernalization and a short photoperiod on the duration of the period from shooting to heading was on average 8 (5.1–10.6) days and on their earliness per se 6 (4.8–8.2) days. Paratypic variability reflects the range of variation for these indicators. In Dagestan, vernalization temperatures and insensitivity to a short day are the main factors determining the earliness of local barleys in their native environment.
