Abstract. The aim of the work is to conduct a phytopathological assessment of new domestic potato varieties in the conditions of the Central Region and to identify among them samples that are characterized by a high stable level of resistance to diseases. Methods. The research was carried out at the experimental base “Korenevo” in the Moscow region in 2019–2020. The soil is sod-podzolic sandy loam. The SCC of the growing seasons in 2019 is 1.39 (wet) and in 2020 2.1 (wet). The object of research is 45 varieties of domestic selection from different scientific institutions. All counts were carried out in accordance with standard methods on a natural infectious background. Results. The agrometeological conditions of the growing seasons of 2019 and 2020 contributed to the development of late blight and were satisfactory for the defeat of potato tops by alternariasis. The prevalence of rhizoctoniosis was different – moderate-depressive in 2019 and high in 2020. The lowest incidence over these years was noted only in the Morning variety-1 % (viral diseases). Potato varieties without symptoms of plant damage by rhizoctoniosis – Merchant and Morning, wrinkled mosaic – 19 varieties (41.3 %), twisting of leaves – 32 varieties (69.6 %) were identified. 33 (73.3 %) cultivars showed high resistance (8–9 points) to late blight, and 13 (28.9 %) to alternariasis. The varieties Kupets, Mariinskiy, Prizer, Tret’yakovka, Alyaska, Brusnichka, Kumach, Plamya, Signal, and Utro were distinguished by their complex resistance to these diseases. The autumn tuberous analysis showed that in 21 varieties (46.7 %) tubers were not affected by rhizoctoniosis, 28 (62.2 %) – scab, 11 (24.4 %) – wet rot. On the varieties of Lingonberry, Northern Lights, Signal and Sokur and on the hybrid G-6-14-11 no tubers with defects were found. Scientific novelty. A comprehensive phytopathological assessment of new domestic potato varieties in relation to the conditions of the Moscow region was carried out and samples with plant and tuber resistance to major diseases were identified.

Comprehensive Study

Целью комплексного исследования, выполненного в Меньковском филиале АФИ в 20122017 годах была оценка вредоносности возбудителя фитофтороза в зависимости от почвенноагрохимических и погодноклиматических условий. Методической основой исследования служил длительный полевой опыт агрофизический стационар в системе полевого и овощекормового севооборотов, в которых картофель возделывали по обороту пласта многолетних трав после озимой ржи и после ячменя. Объектами исследования служили: картофель раннеспелого сорта Ломоносовский среднеустойчивого к возбудителю фитофтороза по клубням и слабоустойчивого по ботве дерновоподзолистая почва средней, хорошей и высокой степени окультуренности и системы удобрения культуры. Супесчаная почва опыта характеризовалась рНКСl 5,26,3, содержанием гумуса 2,13,7, подвижных соединений P2О5 195676 мг/кг и К2О 97298 мг/кг. На хорошо окультуренной и высокоокультуренной почвах их поддерживали применением под картофель 35 и 70 т/га органических удобрений соответственно. Факторы исследования: степень окультуренности почвы (варианты: средняя, хорошая и высокая) и уровень применения минеральных удобрений в расчете на заданный КПД (коэффициент полезного действия фотосинтетически активной радиации) (варианты: КПД ФАР, 13 без удобрений КПД ФАР, 24 N80P20K100 КПД ФАР, 35 N120P30K150). В ходе комплексного исследования установлены параметры поражения возбудителем фитофтороза и уровень потерь урожая картофеля в зависимости от агроклиматических и почвенноагрохимических условий. Агрономическая эффективность изученных вариантов системы удобрения на культуре картофеля высокая. Уровень прибавок урожайности клубней и окупаемость 1 кг д.в. удобрений достигли 3358 и 8,311,6 з.ед. (зерновых единиц) на минеральной, 2545 и 3,98,0 з.ед. на органической и 3379 и 3,86,7 з.ед. на органоминеральной системе удобрения. В неэпифитотийных условиях (2 из 3 лет наблюдений) на фоне низких и умеренных показателей поражения общие потери урожая составляют 5, а окультуривание почвы и применение органических и минеральных удобрений снижают их на 3080. На эпифитотийном фоне, повторяющемся 1 раз в 3 года, пораженность ботвы и клубней картофеля возрастает в 4,3 и 6,1, интенсивность поражения в 2,8 и 3 и развитие в 12 и 17,5 раза соответственно. В эпифитотийные годы потери урожая возрастают в 5,2 раза (до 26), а минеральная система удобрения сокращает их только на среднеокультуренной почве. На этом фоне повышение степени окультуренности почвы и доз органических удобрений до высокого уровня неэффективно.Late blight is one of the most harmful potato diseases in the NorthWest of Russia. Today, its negative effects are aggravated by weather and climate changes. The goal of a comprehensive study carried out in the Menkovsky branch of the Agrophysical Institute in 2012 2017 was an assessment of the harmfulness of the late blight pathogen depending on soilagrochemical, weather and climate conditions. The methodical basis of the research was a prolonged field agrophysical stationary experiment in the system of field and vegetablefeed crop rotations, where potato was cultivated after winter rye and after barley, which, in turn, were grown after perennial grasses. The objects of the study were potato Lomonosovsky, sodpodzolic soil with different degree of cultivation and fertilizer systems for the culture. Potato Lomonosovsky is early ripening variety, its tubers are medium resistant to the late blight agent, and its tops are weakly resistant to it. The sodpodzolic soil had average, good and high cultivation degree. Sandy loam soil in the experiment had the value of pHKCl of 5.2 6.3, the humus content of 2.1 3.7, the content of mobile P2O5 and K2O compounds of 195 676, 97 298 mg/kg, respectively. In well and highly cultivated soils, these parameters were maintained by the application of 35 and 70 t/ha of organic fertilizers for potato, respectively. The experimental factors were the degree of soil cultivation (average, good and high) and the level of mineral fertilizer application for a given efficiency of photosynthetically active radiation (PAR efficiency of 1 3, without fertilizers PAR efficiency of 2 4, N80P20K100 PAR efficiency of 3 5, N120P30K150). In the course of the comprehensive study, the parameters of potato damage by late blight and the level of crop losses were established depending on the agroclimatic soilagrochemical conditions. Agronomic efficiency of the studied variants of the fertilizer system for potato was high. The level of tuber yield increase and payback of 1 kg of fertilizers active substances reached 33 58 and 8.3 11.6 cereal units (CU) for the mineral system, 25 45 and 3.9 8.0 CU for the organic one, and 33 79 and 3.8 6.7 CU for the organic and mineral fertilizer system. Under nonepiphytotic conditions (2 of 3 years of the observation), against the background of low and moderate damage rates, the total yield loss was 5, and the soil improvement and organic and mineral fertilizer application reduced them by 30 80. Against an epiphytotic background, repeated 1 time in 3 years, the damage of tops and potato tubers increases by a factor of 4.3 and 6.1, the intensity of the damage grew 2.8 and 3 times, and the development increases by a factor of 12 and 17.5 times, respectively. In the epiphytotic years, yield losses increased 5.2 times (up to 26), and the mineral fertilizer system reduced them only in medium cultured soil. Against this background, increasing the soil cultivation degree and organic fertilizer doses to a high level is ineffective.

Purpose The problem of parameter identification for biaxial piezoelectric stages is still a challenging task because of the existing hysteresis, dynamics and cross-axis coupling. This study aims to find an accurate and systematic approach to tackle this problem. Design/methodology/approach First, a dual-input and dual-output (DIDO) model with Duhem-type hysteresis is proposed to depict the dynamic behavior of the biaxial piezoelectric stage. Then, a systematic identification approach based on a modified differential evolution (DE) algorithm is proposed to identify the unknown parameters of the Duhem-type DIDO model for a biaxial piezostage. The randomness and parallelism of the modified DE algorithm guarantee its high efficiency. Findings The experimental results show that the characteristics of the biaxial piezoelectric stage can be identified with adequate accuracy based on the input–output data, and the peak-valley errors account for 2.8% of the full range in the X direction and 1.5% in the Y direction. The attained results validated the correctness and effectiveness of the presented identification method. Originality/value The classical DE algorithm has many adjustment parameters, which increases the inconvenience and difficulty of using in practice. The parameter identification of Duhem-type DIDO piezoelectric model is rarely studied in detail and its successful application based on DE algorithm on a biaxial piezostage is hitherto unexplored. To close this gap, this work proposed a modified DE-based systematic identification approach. It not only can identify this complicated model with more parameters, but also has little tuning parameters and thus is easy to use.

Цель исследования усовершенствование способа обогащения растений чеснока селеном до уровня суточной нормы потребления путем обработки вегетирующих растений растворами селенитов натрия и калия в сочетании с поверхностно-активными веществами и диметилсульфоксидом. Исследования проведены во ВНИИО филиале ФГБНУ ФНЦО, в условиях открытого грунта в 20162018 годах, на супесчаной почве, содержание гумуса в которой составляло 3,413,44, рНKCl 6,7, степень обеспеченности питательными веществами: фосфором высокая (содержание P2O5 в слое 020 см составляло 22,7824,62 мг (по Чирикову) калием низкая, содержание К2О в слое 20 см 10,3817,88 мг (по Масловой). Для улучшения минерального питания растений осенью под основную обработку в почву вносили калий хлористый в дозе 50 г/м2, в период вегетации проводили подкормки растений: первую, в фазе начала интенсивного роста листьев аммиачной селитрой 30 г/м2, вторую, через две недели после первой сульфатом калия 50 г/м2. Погодные условия в течение периода исследований были благоприятны для выращивания чеснока. Поливы проводили по мере подсыхания верхнего слоя почвы. Исследования проведены на чесноке озимом сорта Гладиатор. Схема опытов предполагала предпосадочное замачивание зубков в течение 30 мин. и последующую двукратную обработку вегетирующих растений 0,1-ным раствором селенита натрия и калия в сочетании с поверхностно активными веществами (1) и диметилсульфоксидом (1): первый раз в фазе начала интенсивного роста листьев и второй через три недели. Установлено, что некорневая обработка растений селенитом натрия была в 2,3 раза, а селенитом калия в 5,8 раза эффективнее, чем корневая. Сделан вывод о том, что луковицы чеснока, полученные, в результате некорневой обработки растений 0,1-ным раствором селенита натрия и калия в сочетании с поверхностно активными веществами и диметилсульфоксидом содержат в 145,3169,8 раза больше селена, чем контроль, что позволяет получить зубки, содержащие селен в концентрации 6,837,98 мг/кг. Суточная норма потребления чеснока составляет примерно 10 г, средняя потребность в селене составляет от 30 до 70 мкг. Учитывая, что содержание селена в обогащенной продукции составит 68,3 79,8 мкг/10 г чеснока предложенный способ обогащения позволяет в полной мере удовлетворить суточную потребность организма человека в этом микроэлементе.The aim of investigation was to improve the method of enrichment of garlic plants with selenium to the level of daily consumption rate by treatment of vegetative plants with solutions of sodium and potassium selenites in combination with surfactants. The investigations were carried out at ARRIVG branch of FSCVG, in open ground in 20162018, on sandy loam soil with humus content of 3.413.44, pHKCl 6.7, content of phosphorus (P2O5) in the layer 020 cm was 22.7824.62 mg (Chirikov) content of potassium (K2O) 10.3817.88 mg (Maslova). To improve mineral nutrition of plants fall under the basic treatment in the soil was added potassium chloride at a dose of 50 g/m2 during the growing season were plant nutrition: first, in the early phase of intensive growth of leaves ammonium nitrate 30 g/m2, the second, two weeks after the first potassium sulphate and 50 g/m2. Weather conditions during the period of growth were favorable for growing garlic. Watering was carried out at the periods where the top layer of soil was dried. Studies were carried out on variety Gladiator of winter garlic. The experimental design included soaking the cloves for 30 minutes before planting, and subsequent double treatment of vegetating plants with 0.1 solution of sodium and potassium selenite in combination with surfactants (1) and dimethyl sulfoxide (1): the first time in the phase of the beginning of intense leaf growth and the second time after 3 weeks. As a result of the investigations it was found that non-root treatment of plants with solutions containing selenium was more effective than root treatment. Non-root top dressing with sodium selenite was in 2.3 times, and potassium selenite in 5.8 times more effective than root. It is concluded that garlic bulbs obtained as a result of non-root treatment of plants with 0.1 solution of sodium and potassium Selenite in combination with surfactants and dimethylsulfoxide contain 145.3169.8 times more selenium than control, which allows to obtain teeth containing selenium in a concentration of 6.837.98 mg/kg. The daily consumption rate of garlic is approximately 10 g, the average need for selenium element is from 30 to 70 micrograms. Because of content of selenium in enriched products consisted of 68.3-79.8 mcg/10 g of garlic, the proposed method of enrichment allows to fully satisfy the daily need of the human body at this microelement.

The results of studying the elements of the technology of cultivation of a new variety of winter rye Sudarushka are presented. The research took place in 2019, 2020 in the sub-taiga zone of the Tomsk region. The impact of soil cultivation methods as well as the impact of humic fertiliser from peat Gumostim on the yield of winter rye Sudarushka is evaluated. The soils of the experimental plot are acidic (pH 4.3) soddy-podzolic loamy sandy loam. The arable horizon has a low humus content (1.5%), a low (0.2 mg/100g) content of nitrate nitrogen, a medium content of mobile phosphorus (19.2) and exchangeable potassium (7.1) and a high (11.0 mg/100g) content of mobile aluminium. The scheme of the experiment included four variants of cultivation: ploughing of fallow lands with PlN-4-35 + cultivation KPN-4,2, sowing without packing and with packing; disking with BDMK-2,8 + cultivation KPN-4,2, sowing without packing and with packing. Treatment with humic fertilizer from peat Gumostim at a concentration of 0.001% was carried out during the growing season in the beginning phase of the leaf-tube formation. The average yield of winter rye in the variety Sudarushka during the years of research was 4.66 t/ha in the variant with disking, subsequent cultivation before sowing and further sowing with packing, which is 0.34 t/ha higher than with the traditional method of soil cultivation. The application of humic fertilizer from peat Gumostim on cold sod-podzolic soils enabled the average yield of winter rye to be 4.31 t/ha y, which is 0.39 t/ha higher than without the fertilizer.
