Relevance. Irrigation of agricultural crops plays a key role not only in increasing the yield of these crops, but also in preserving it, especially under stressful temperature conditions. One of the effective methods of water conservation during irrigation is drip irrigation. Drip irrigation technology allows you to accurately dose water, taking into account the needs of specific crops and maintaining an optimal level of soil moisture. It is important to note that this technology helps save water and reduce the risk of soil overmoistening. In addition to drip irrigation, there is also aerosol irrigation. This irrigation technology allows more efficient use of water resources and provides optimal conditions for the ground air layer for the growth and development of plants under stressful temperature conditions.Methods. The objectives of the study are to study the technologies and technical means of irrigation of a young cherry orchard to maintain optimal modes through the use of drip irrigation with aerosol irrigation in the Central part of the Non-Chernozem zone of Russia. During the research, two factors were analyzed: studying the impact of various irrigation methods and moistening volumes on the formation of trees of the Gostinets and Zhukovskaya varieties of sweet cherry.Results. The field experiment is conducted on the territory of «Kolomenskaya Yagoda» LLC in the Moscow Region. The conducted studies have shown that the selected irrigation method using a combined irrigation system on sod-podzolic soils in the central part of the Non-Chernozem zone of Russia for growing a young cherry orchard of the Gostinets and Zhukovskaya cherry varieties meets the criteria of environmental safety and economic efficiency.Conclusion. From the point of view of profitability, it is most effective to grow a young cherry orchard by maintaining humidity in the root zone of the soil within 80-100% of the lowest moisture capacity and relative humidity of the ground air layer in the range of 55-70%.

Relevance. Xanthomonas campestris pv. campestrisis a widespread bacterial pathogen that causes a black rot disease of Brassicaceae plants. It is distributed across all territories with cultivated brassica crops and has high economic significance. One of the known Xanthomonas pathogenicity factor is TAL-effectors. These proteins penetrate in plant nucleus and change expression of some host genes in order to promote infection. For some Xanthomonas species TAL-effectors are a key of bacteria success, however for Xcc their role is still remain obscure as well as TALE occurrence among Xcc belonged to different races and originated from different regions. The goal of our study was examination of TALE distribution among Xcc isolates collected in Russia.Methods. Sample of the Xcc isolates mainly collected in Moscow region and Krasnodar krai was used for TALE search. Bacterial total DNA was isolated using CTAB method. Four primer pairs were used for TALE genes detection by amplification conservative regions.Results. Among 50 isolates only 4 isolates possessed TALE were revealed. Low-frequency occurrence of TALE among Russian isolates can reflect Xcc population features in Moscow region and Krasnodar krai as well as genotype features of cultivated plant hosts.

Relevance. An increase in the spread of bacteriosis on beetroot in the conditions of the Moscow region carries an epidemiological danger, which actualizes research on the development of a method-ology for evaluating table beet plants for resistance to bacteriosis in the early stages of ontogenesis. The aim of the research. To identify the nature of the relationship between the reaction of sporophyte and microgametophyte to infection with Pseudomonas syringae pv. aptata (Psa) bacterium of beet-root varieties with different resistance of root crops to bacteriosis.Materials and methods. Objects of research: beetroot plants of the Marusya and Krasny Barhat varietal populations, collection strain Psa 1-21. Using phytopathological methods and methods of gamete breeding, plant resistance was assessed in various variants of infection of sporophyte and gametophyte with suspension and culture filtrate of Psa.Results. The average volume of the affected area of the Psa root crops of the Marusya variety was 3.5 times greater than that of the Krasny Barhat variety (Vp = 53 mm3), which is characterized by alignment and absence of susceptible forms (Vp >300 mm3). The Marusya variety has a wide intrapopulation polymorphism in the stability of root crops and leaves, where most genotypes showed medium or high susceptibility to the pathogen. Both varieties showed an increase of 10-30% relative to the control of pollen viability at high (CFU 12*108 cl/ml) and low (CFU 2.4*108 cl/ml) concentrations of the pathogen. The positive effect of Psaon the growth of pollen tubes was noted: in the Marusya variety, as the concentration increased, the stimulating effect increased, in the Krasny Barhat variety, it gradually decreased. When adding a 2.5-fold diluted Psa culture filtrate, the susceptible Marusya variety showed an increase in pollen viability (by 3%), and the resistant Krasny Barhat variety showed a 24% decrease relative to the control. According to the growth rate of the pollen tube, the 4:6 dilution was also differentiating, where the average length of the tubes of the susceptible variety exceeded the control by 10%, and in the stable variety it was 18% lower than the control variant.Conclusion. An inverse relationship was revealed between the resistance of sporophyte to Psa and changes in the functional parameters of the microgametophyte of beetroot varieties Marusya and Krasny Barhat under the influence of a phytopathogen. The results obtained indicate the prospects for the development of a methodology for the selection of bacteriosis-resistant genotypes of beetroot by the reaction of microgametophyte.

Relevance. Modern globalization, internationalization, regional competitive differentiation actualize geoeconomic modeling methods for geopolitical planning, management and control. The novelty of the proposed solutions is the proposed concept, based on the translation of the ideas of theoretical mechanics into economics.Methodology. Considering the annual values of statistical indicators of territorial concentrates as a system of geographically distributed objects (subjects of the Russian Federation), it is possible to determine the geographic barycenter. Knowing the values of the geocoordinates of the barycenter, it is possible to determine the tendencies and trend of the barycenter movement as an indicator of the dynamics of the system under consideration through the analysis of the dynamics of these coordinates. Based on Russtat data on the annual gross harvest of agricultural crops (vegetables), population by constituent entities of the Russian Federation for the period 1991-2021, data on the coordinates of the administrative centers of the constituent entities of the Russian Federation, the values of the geographic coordinates of the barycenter of vegetable growing in Russia were calculated.Results. For 2021, the geographic coordinates of the barycenter of vegetable growing in Russia are 50.30° N and 49.49° E with an average regional value with an average regional annual vegetable har-vest of 1722.52 million centners/year and fluctuations in the coordinates of the barycenter in the zone of 3-4 geographic degrees or three hundred territorial kilometers with a pronounced south-west trend Analysis of the dynamics of the barycenter for the period 1991-2021. will allow to reveal a slight shift of the vegetable growing barycenter to the south by 3.5 degrees with an increase in the average regional vegetable harvest by 124.11 million centners per year for each degree (or the all-Russian by more than 9,500 million centners per year for each degree to the south), a slight shift of the vegetable growing barycenter to the west by 4.5 degrees with an increase in the average regional vegetable har-vest by 86.5 million centners per year per degree (or the All-Russian by more than 6,660 million cent-ners per year for each degree to the west). For the period 1991-2021, two opposite trends in the devel-opment of vegetable growing are distinguished. In the period from 1991 to 2000, the movement of the coordinate of the vegetable growing barycenter went in the direction of the northeast of Russia, in the period 2000 to 2021 -- on the contrary, to the southwest.The conclusion is made about the existence of a relationship between the development of vegetable growing and the geopolitics of Russia in the period under review. The obtained method and results can be used in strategic state management of agricultural production in Russia.
