    Relevance. The annual increase in the area under the eggplant culture in small farms and the individual sector is explained by high nutritional, dietary, taste, and also the multi-purpose use of fruits. For optimal growth and development, eggplant needs a high amount of active temperature, which greatly limits the cultivation of crops in many regions of Russia. However, the egg-plant growing area is expanded through the use of industrial and film unheated greenhouses. The development of technology elements for growing eggplant in film greenhouses is relevant, as it contributes to an increase in the area of farms.Materials and methods. The aim of the research was to substantiate the elements of the technology for growing eggplant in film unheated soil greenhouses. The studies were carried out in 2018-2019 at the base of the Educational and Scientific Production Center “Vegetable Experimental Station named after IN AND. Edelstein» RGAU-Moscow Agricultural Academy named after K.A. Timiryazev in the summer-autumn turnover in a film unheated soil greenhouse. The objects of research were varieties and F1 eggplant hybrids: F1 Borovichok, F1 Bagira, F1 Tender, F1 Patio Trio, as a control they used a hybrid F1 Pelican; eggplant varieties: Mushroom pleasure, Black handsome, Don Quixote, they used the Frant variety as a control.Results. In general, based on the results of studying the influence of the formation of two and three stalked eggplant varieties and hybrids on the total yield in the conditions of summer-autumn turnover in film soil greenhouses, we recommend that all studied hybrids and varieties be grown in three shoots.Актуальность. Ежегодное увеличение площадей под культурой баклажана в малых фермерских хозяйствах и индивидуальном секторе объясняется высокими питательными, диетическими, вкусовыми качествами, а также многоцелевым использованием плодов. Для оптимального роста и развития баклажану необходима высокая сумма активных температур, что сильно ограничивает выращивание культуры во многих регионах России. Однако зону выращивания баклажана расширяют за счёт использования промышленных и пленочных необогреваемых теплиц. Разработка элементов технологии выращивания баклажана в пленочных теплицах является актуальной, так как способствует увеличению площадей в фермерских хозяйствах.Материал и методы. Целью исследований являлось обоснование элементов технологии выращивания баклажана в пленочных необогреваемых грунтовых теплицах.

    Influence of parametric instability on spin pumping by dipole-exchange magnetostatic surface waves in YIG–Pt structures

    The purpose of this work is to study the influence of four-magnon (4M) parametric instability on spin pumping by dipole-exchange magnetostatic surface waves (MSSW) with the help of the inverse spin Hall effect (ISHE) in structures based on yttrium-iron garnet (YIG) and platinum (Pt). Methods. The experiments were carried out using the delay line structures based on YIG(900 nm)/Pt(9 nm) where electromotive force (EMF) induced by ISHE demonstrates a growth at the frequencies of the resonant interaction between MSSW and volume exchange modes. The frequency dependencies of the amplitude and phase for the delay line structure and EMF (U(f)) from the platinum layer were studied as a function of the MSSW power. Results. It was shown that the resonant EMF growth at the frequencies of dipole-exchange resonances is caused by the presence of Van Hove singularities in the density of states for spin waves at such frequencies that leads to an increase in the efficiency of electron-magnon scattering at the YIG–Pt interface. A growth in MSSW power beyond the threshold of 4M instability development results in a “smoothing” of resonant particularities in the EMF frequency dependence U(f) that can be explained by decreasing efficiency of spin pumping due to destruction of dipole-exchange resonances and related singularities in the density of states of spin waves. Conclusion. Obtained results may be of interest for the development of highly sensitive spin current detectors, as well as for the implementation of spintronic devices.&nbsp

    Relevance and methods. Leek is one of the most promising onion crops for industrial cultivation in the Non-Chernozem zone, which has medicinal properties and high nutritional value. The results of studying the technological features of leek cultivation in the open ground of the Moscow region are presented. The studies were carried out in 2019-2020 on the territory of the “Vegetable Experimental Station named after V.I. Edelstein". We studied the influence of the feeding area of leek seedlings on the biometric parameters of plants and the quality of products. The object of the study is the variety Karantansky, experimental options: 1) seedling feeding area – 6 cm2 (control), 2) seedling feeding area – 8 cm2 , 3) seedling feeding area – 10 cm2 . The objects of research to study the content of ascorbic acid were leek varieties: late-ripening – Karantansky (standard), Bandit, Dobry Molodets, mid-ripening – Columbus, Hobot slona.Results. It is noted that the feeding area during the seedling period does not significantly affect the biometric parameters of leek plants: leaf area, plant weight, leek pseudostems diameter. Therefore, during the period of growing seedlings, from the point of view of rational use of the area in the seedling department, it is recommended to use the minimum feeding area – 6 cm2 . It was also found that the studied varieties accumulate ascorbic acid in different ways in various plant organs. The maximum content of ascorbic acid was noted in the leek pseudostems of the control late-ripening variety Karantanskiy – 23.6 mg%. The minimum values are for Dobry Molodets (11.8 mg%) and Hobot Slona (11.9 mg%).Актуальность. Лук порей – одна из наиболее перспективных луковых культур для промышленного выращивания в условиях Нечерноземной зоны, обладающая лечебными свойствами и высокой питательной ценностью.Материал и методы. Представлены результаты изучения технологических особенностей культивирования лука порея в условиях открытого грунта Московской области. Исследования проводили в 2019-2020 годах на территории УНПЦ «Овощная опытная станция имени В.И. Эдельштейна». Изучали влияние площади питания рассады лука порея на биометрические показатели растений и качество продукции. Объект исследования – сорт Карантанский, варианты опыта: 1) площадь питания рассады – 6 см2 (контроль), 2) площадь питания рассады – 8 см2 , 3) площадь питания рассады – 10 см2 . Объектами исследований по изучению содержания аскорбиновой кислоты являлись сорта лука порея: позднеспелые – Карантанский (стандарт), Бандит, Добрый молодец, среднеспелые – Коламбус, Хобот слона.Результаты. Отмечено, что площадь питания в рассадный период не оказывает существенного влияния на биометрические показатели растений лука порея: площадь листьев, масса растения, диаметр ложного стебля. Поэтому в период выращивания рассады, с точки зрения рационального использования площади в рассадном отделении, рекомендуется использовать минимальную площадь питания – 6 см2. Также установлено, что изучаемые сорта по-разному накапливают аскорбиновую кислоту в различных органах растения. Максимальное содержание отмечено в ложном стебле растений контрольного позднеспелого сорта Карантанский – 23,6 мг%. Минимальными значениями у сортов Добрый Молодец (11,8 мг%) и Хобот слона (11,9 мг%)

    Peasant settlers and the ‘civilizing mission’ in Russian Turkestan, 1865-1917

    Get PDF
    This article provides an introduction to one of the lesser-known examples of European settler colonialism, the settlement of European (mainly Russian and Ukrainian) peasants in Southern Central Asia (Turkestan) in the late nineteenth and early twentieth centuries. It establishes the legal background and demographic impact of peasant settlement, and the role played by the state in organising and encouraging it. It explores official attitudes towards the settlers (which were often very negative), and their relations with the local Kazakh and Kyrgyz population. The article adopts a comparative framework, looking at Turkestan alongside Algeria and Southern Africa, and seeking to establish whether paradigms developed in the study of other settler societies (such as the ‘poor white’) are of any relevance in understanding Slavic peasant settlement in Turkestan. It concludes that there are many close parallels with European settlement in other regions with large indigenous populations, but that racial ideology played a much less important role in the Russian case compared to religious divisions and fears of cultural backsliding. This did not prevent relations between settlers and the ‘native’ population deteriorating markedly in the years before the First World War, resulting in large-scale rebellion in 1916
