Цель работы – в результате многолетней оценки выявить сорта и гибриды среднеспелой моркови столовой для переработки на соковую продукцию. Исследования были проведены в 2012–2021 годах на экспериментальной базе ВНИИО-филиала ФГБНУ ФНЦО. Корнеплоды моркови столовой выращивали в открытом грунте с нормой высева для образцов сортотипа Берликум/Нантская 1,2 млн шт/га, Шантенэ – 0,9 млн шт/га. Ежегодно анализировали 7 сортов и 5 гибридов среднего срока созревания, сортотипов Шантенэ и Берликум/Нантская селекции ФГБНУ ФНЦО, ООО «Агрофирма «Поиск», иностранной компании «Bejo Zaden». Контролем служили гибриды F1 Каскад и F1 Балтимор. В лабораторных условиях корнеплоды оценивали на содержание сухого вещества (метод высушивания), суммы сахаров (рефрактометрический метод) и на выход сока (метод отжима). В работе использовали соковыжималку марки Scarlett SC-JE50S51. Анализ полученных данных показал, что в корнеплодах моркови столовой, выращенных в условиях Московской области, содержание сухого вещества и суммы сахаров имели среднюю изменчивость (CV=10,8–12,1% и CV=10,2–12,1% соответственно). Выход сока имел незначительную изменчивость (CV=6,9–9,1%) и варьировал в зависимости от сортотипа. Отмечено, что наибольший выход сока в сортах и гибридах сортотипа Шантенэ (501–529 мл/кг при коэффициентах вариации CV=8,1–9,1%). В сортах и гибридах сортотипа Берликум/Нантская выход сока варьировал от 470 до 502 мл/кг при коэффициентах вариации CV=6,9–8,9%. Максимальный выход сока отмечен у сортов Рекси (540 мл/кг), Шантенэ роял (521 мл/кг), Шантенэ королевская (510 мл/кг), Нанте (502 мл/кг) и гибрида F1 Бейби (501 мл/кг). Установлено, что метеорологические условия вегетационных периодов в средней степени влияют на содержание сухого вещества (CV=10,8–12,1%) и сахаров (CV=10,2–12,1%) и незначительно на выход сока (CV=6,9–9,1%). The purpose of the work is to identify varieties and hybrids of medium-ripe carrots for processing into juice products as a result of a long-term evaluation. The research was carried out in 2012–2021 at the experimental base of ARRIVG - branch of FSBSI FSVC. Canteen carrot roots were grown in the open ground with a seeding rate for samples of the variety type Berlicum/Nantes 1.2 million pcs/ha, Chantenay – 0.9 million pcs/ha. 7 varieties and 5 hybrids of the average ripening period, variety types Chantenay and Berlicum/Nantes were analyzed annually breeding of FSBSI FSVC, LLC «Agrofirma «Poisk», foreign company «Bejo Zaden». The control was the F1 Kaskad and F1 Baltimor hybrids. Under laboratory conditions, root crops were evaluated for dry matter content (drying method), sugar amounts (refractometric method) and juice yield (extraction method). A Scarlett SC-JE50S51 juicer was used in the work. The analysis of the obtained data showed that in the root crops of carrots grown in the conditions of the Moscow region, the dry matter content and the amount of sugars had an average variability (CV=10.8–12.1% and CV=10.2–12.1%, respectively). The juice yield had a slight variability (CV=6.9–9.1%) and varied depending on the variety type. It was noted that the highest yield of juice in varieties and hybrids of the Chantenay variety type (501–529 ml/kg with coefficients of variation CV = 8.1–9.1%). In varieties and hybrids of the Berlicum/Nantes variety type juice yield varied from 470 to 502 ml/kg with coefficients of variation CV =6.9–8.9%. The maximum juice yield was noted in the varieties Rexy (540 ml/kg), Chantenay Royal (521 ml/kg), Chantenay Korolevskaya (510 ml/kg), Nante (502 ml/kg) and F1 Baby hybrid (501 ml/kg). It was found that the meteorological conditions of the growing seasons have an average effect on the dry matter content (CV=10.8–12.1%) and sugars (CV=10.2–12.1%) and slightly on the juice yield (CV=6.9–9.1%).

Maize is the very important silage source in the world. Timely harvesting ensure high maize forage yield and quality. Therefore, the study focused on the effects of four harvesting times (starting at the 12 August every 7 days) on yield and qualitative parameters of forage green mass of maize hybrid ZP 677. The experiment was set in Vojvodina Province, Serbia, during the 2013 and 2014 growing seasons. Plant height, stem diameter, number of leaves per plant, ear percentage, forage yield, dry matter content and crude protein content were higher, while stem percentage was lower in 2014 with favorable climatic condition. Forage yield, crude protein content, ADF and NDF decreased, while dry matter content significantly increased with delay in harvesting. The maize hybrid should be harvested when the milk line is three-quarter of the way down the grain that is in the third decade of August.

The authors showed the results of studies of productivity parameters of different early maturing maise hybrids depending on the method of sowing. Experiment included 5 variants: single- seeded hybrids Kubansky 101 and Kubansky 500, Kubansky 101 + Kubansky 500 (50 + 50% of the full seeding rate), Kubansky 101 + Kubansky 500 (25 + 75%) and Kubansky 101 + Kubansky 500 (75 + 25%). The authors carried out a biological yield survey on 10 September. This recording showed that the ultra-early-ripening hybrid Kubansky 101 CB was in the phase of milk-wax maturity of the grain, and the late-ripening Kubansky 500 CB was in the phase of cob formation. In single-species crops, the yields were naturally higher. The late-maturing hybrid yielded 82.0 t/ha, 38.1 t/ha higher than the ultra-maturing hybrid. However, the dry matter yield of the second hybrid was 15.9 % higher, and the cob yield was 29 % higher. The dry matter concentration of the hybrid Kubansky 500 was only 18.8 %. The hybrid Kubansky 101 CB had a dry matter concentration of 34.7 %. Different variations with the ratio of hybrids of different ripeness groups in the sowing showed that in green matter yield, the variants where the proportion of late-ripening hybrid is higher are superior. Thus, the presence of 75% hybrid Kubansky 500 CB allowed obtaining the highest yield of 77.2 t/ha. This yield is almost two times higher than the yield of the single-variety ultra-ripening hybrid (43.9 t/ha). However, the dry matter concentration here was 20.2 %. According to the biochemical analysis of the silage batches harvested, all the forages were benign. No oily acid was detected, and lactic acid predominated over acetic acid. Hay prepared from hybrid Kubansky 101 SV was 33.8% in dry matter content, which compares favourably with silage prepared from hybrid Kubansky 500 SV and mixtures with Kubansky 101 SV. The hybrid Kubansky 500 SV and mixtures with Kubansky 101 SV accounted for 21 % dry matter content. In silage prepared from hybrid Kubansky 101 SV, the percentage of dry matter is 24.2-25 %.

В статье отражены результаты изучения влияния сорта и различных систем механической очистки клубней на качество картофеля в вакуумной упаковке. Исследования проводились в 2015–2018 годах на экспериментальной базе ФГБНУ ВНИИКХ (Московская область, Люберецкий район). Опыт двухфакторный: фактор А – сорт (110 сортообразцов), фактор Б – тип механической системы очистки клубней (ножевая, абразивная и перфорированная ячеистая). Качество продукта по показателям устойчивости мякоти к потемнению и сохранности тургора клубней определяли через 5, 10 и 15 дней после вакуумирования при переработке в сентябре, январе и апреле. Температура хранения сырья 5–7 °С, относительная влажность воздуха в хранилище 90–95%. В результате исследований установлено, что сорта картофеля для вакуумной упаковки должны соответствовать следующим требованиям: содержание сухого вещества не ниже 20%; отходов при механической очистке не более 20% при сентябрьском сроке переработки и использовании системы очистки ножевого типа; устойчивость мякоти клубней к потемнению не ниже 7 баллов через 15 дней хранения в вакуумной упаковке; предпочтительный цвет мякоти – кремовый и желтый. Выявлено, что глубина выреза более 5 мм на поверхности клубней при ручной доочистке крайне негативно влияет на качество вакуумированного картофеля. Из 110 изученных сортов для вакуумной упаковки рекомендованы 40, соответствующие вышеуказанным требованиям, например, такие, как Лилея, Ломоносовский, Люкс, Утенок, Холмогорский, Амур, Бриз, Былина Сибири, Гала, Горняк, Манифест, Памяти Лорха, Русский сувенир, Лина, Барин, Златка, Надежда, Сиреневый туман, Фаворит, Фрителла. Установлено, что использование рекомендуемых сортов и механической системы очистки ножевого типа (режим работы 80 сек.), по сравнению с абразивным и ячеистым, способствует снижению отходов при переработке в среднем за сезон на 4,8% при одновременном сохранении высокого качества конечного продукта. The article presents the results of studying the influence of potato varieties and various mechanical tuber peeling systems on quality of vacuum-packed potato. Researches were conducted in 2015–2018 at the experimental base of Lorch Potato Research Institute (Moscow region, Lyuberetsky district). Two-factor experiment: factor A – potato variety (amount 110), factor B – type of mechanical tuber peeling system (blade, abrasive and perforated cellular). The quality of the product according to the indicators of pulp darkening resistance and the safety of the tuber turgor was determined 5, 10 and 15 days after vacuuming when processing in September, January and April. Potato store temperature was 5–7 °C, the relative humidity in the storage – 90–95%. As a result of research, it was found that potato varieties suitable for vacuum packaging must meet the following requirements: dry matter content not less than 20%; losses during mechanical peeling not more than 20% when processing in September and using a blade-type peeling system; resistance of the tuber pulp to darkening not less than 7 points after 15 days of storage in a vacuum package; the preferred color of pulp is cream and yellow. It was found that the depth of the cutout more than 5 mm on the surface of tubers during manual post-peeling has a severe negative effect on the quality of vacuumed potatoes. From 110 studied varieties, 40 ones which meet the above mentioned requirements were recommended for vacuum packaging, such as Lilea, Lomonosovsky, Lux, Utenok, Holmogorsky, Amur, Briz, Bilina Sibiri, Gala, Gornyak, Manifest, Pamyaty Lorcha, Russky suvenir, Lina, Barin, Zlatka, Nadezhda, Sirenevy tuman, Favorite, Fritella. It was found that the use of recommended varieties and a mechanical peeling system of blade type (operating mode 80 sec.), in comparison with abrasive and cellular, helps to reduce losses while processing by an average of 4.8% per season and lets to maintain the high quality of the final product.

Production practices that included two seeding methods and seven seeding rates in one study, and a combination of seven seeding and five harvest dates in another, were compared in field studies over a five-year period. Data were collected on dry matter yield and several plant characteristics. The lowest seeding rate in the row plantings produced the highest yield of dry matter every year. Seeding rates had no effect on yield within the broadcast method. Plant weight, stem diameter and leaf content were greater under the row seeding method than under the broadcast system, but none was affected strongly by seeding rate under either method. Plant height and dry matter content at harvest were not affected either by the methods or by the rates of seeding used. On the other hand, date of seeding had a marked effect on the final dry matter content and yield. Early seeding dates produced the highest yields. Dry matter yield increased several-fold throughout the autumn harvest period where mid- to late-season seedings were employed.

The article presents the results of studies of the effect of seeding rates and row spacing on the forage productivity of different alfalfa ecotypes when mowing grass in the flowering stage. In the soil-climatic conditions of the right bank forest-steppe irrespective of the effect of abiotic and biotic factors during the growing season, high adaptability of alfalfa of the southern ecotype of the Angelica variety was established, which formed a stable crop of green mass at the optimal seeding rate (8,0 million/ha) and width 12,5 cm. For an average of two years of grass use, the varieties of alfalfa Rosana and Angelica provided a yield of green mass of 62,96-64,02 t/ha, which was 11,1-14,9% higher than for sowing with the norm of sowing 4,0 million/ha, and 6,3-7,1% with row spacing half (25,0 cm). It was found that in two years of use of alfalfa Angelica variety had higher dry matter content, compared with the variety of Rosana and were respectively 23,05 and 22,98%. There was a gradual decrease in the dry matter content with a thickening of the herbage in the Rosana variety from 23,32 to 22,72% and from the Angelica variety from 23,31 to 22,84%. As the row spacing increased from 12,5 to 25,0 cm, the solids content increased by 0,28-0,62%, or 22,74-22,84 and 23,12-23,36%. The crude protein content in the dry matter of alfalfa plants of both varieties differed by slopes and years of herb use. The highest content of crude protein was obtained in the dry matter for sowing with a row spacing of 12,5 cm, which averaged 21,10% in the Rosana variety and 20,23% in the Angelica variety or increased by 0,79-0,87%, compared to the row spacing of 25,0 cm. Thus, irrespective of the hydrothermal conditions during the growing season of the studied varieties of alfalfa sowing Rosana and Angelika, the average yield of dry matter at the level of 13,64-13,93 and 2,76-2,88 t/ha of crude protein at the width of row 12,5 cm. Key words: alfalfa, variety, flowering start, crude protein, dry matter, yield, green mass.

This research was conducted to determine the effects of different seaweed doses on yield and nutritional values of hydroponic wheatgrass (Triticum aestivum L.) juice in the climatization chamber of Karabuk University, Eskipazar Vocational School, Department of Crop and Animal Production between the dates of 15.01.2015 and 15.06.2015. In the research, four different seaweed doses (Control; 0, D1; 150, D2; 300, D3; 450 and D4; 600 ppm) and control were applied to irrigation water and their effects on the content of biomass rate, biomass and grass yield, grass juice yield and pH, plant height and root length, biomass and grass dry matter rate, grass juice energy and macronutrient values (protein, carbohydrate, fat, dietary fiber and ash) were analysed. According to the results, while the highest biomass and grass yield, plant height values were obtained from D1, D2, D3 and D4 treatments, the highest grass juice yield and root length were obtained from D3 treatment. The highest pH, grass dry matter content was obtained from control treatment. Seaweed dose treatments were not had influence on grass juice energy values. However, the rise in the grass juice yield was caused a rise in the total energy values in the unit area. D3 treatments can be recommendable to achieve the highest grass juice yield.

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.

Цель исследований – дать оценку сохраняемости и болезнеустойчивости современных сортов и гибридов моркови столовой и определить корреляционные зависимости влияния биохимических показателей качества на сохраняемость и степень поражения моркови столовой различными видами болезней в процессе хранения. Исследования проводились в 2011–2016 годах во ВНИИО – филиале ФГБНУ ФНЦО по общепринятым методикам. В биохимической лаборатории отдела земледелия и агрохимии содержание сухого вещества определяли высушиванием до абсолютно сухого веса, общего сахара – по Бертрану, аскорбиновой кислоты – по Мурри, нитраты – ионоселективным методом. При характеристике моркови столовой важнейший показатель, определяющий его качество – количество сухого вещества и сахаров. В процессе хранения были выявлены следующие болезни моркови: серая гниль (Botrytis cinerea Pers. ex Fr.), белая гниль (Sclerotinia sclerotiorum (Lib.)), белая парша (Rhizoctonia carotae Rad.), альтернариоз (Alternaria radicina M., Dr. et E.). В большей степени сортообразцы моркови столовой поражались серой гнилью. Лучшими по сохраняемости сортообразцами были Корсар (94,6%), F1Берлин (94,5%), Берликум Роял (94,1%) и F1 Звезда (94%). Сохраняемость у зарубежных сортов и гибридов моркови столовой была немного выше, чем у отечественных (на 0,4%) как за счет меньшей величины убыли массы (6,3% против 6,4%), так и потерь от болезней (1,6% против 1,9%). Сохраняемость корнеплодов моркови находится в прямой корреляционной зависимости от содержания сухого вещества (r=+0,41), каротиноидов (r=+0,39), моносахаров (r­=+0,30) и суммы сахаров (r=+0,27). Проявление серой гнили находится в обратной корреляционной связи с содержанием сухого вещества и каротиноидов (r=-0,37 и r=-0,35 соответственно), белой парши – в прямой корреляции с содержанием сухого вещества , моносахаров и дисахаров (r= +0,21; r= +0,39; r= -0,41 соответственно), белой гнили в обратной корреляционной связи с содержанием сухого вещества, моносахаров и дисахаров. The purpose of the research is to assess the persistence and disease resistance of modern varieties and hybrids of carrots and to determine the correlation between the influence of biochemical quality indicators on the persistence and degree of damage to carrots by various types of diseases during storage. The research was conducted in 2011–2016 at ARRIVG – branch of FSBSI FSVC, according to generally accepted methods. In the biochemical laboratory of the Department of Agriculture and Agrochemistry, the dry matter content was determined by drying to absolutely dry weight, total sugar – by Bertran, ascorbic acid – by Murri, nitrates – by the ion-selective method. When describing carrots, the most important indicator that determines its quality is the amount of dry matter and sugars. During storage, the following diseases of carrots were detected: gray rot (Botrytis cinerea Pers. ex Fr.), white rot (Sclerotinia sclerotiorum (Lib.), white scab (Rhizoctonia carotae Rad.), alternariasis (Alternaria radicina M., Dr. et E.). To a greater extent, varieties of table carrots were affected by gray rot. The best preserved varieties were Corsar (94.6%), F1 Berlin (94.5%), Berlicum Royal (94.1%) and F1 Zvezda (94%). The persistence of foreign varieties and hybrids of table carrots was slightly higher than that of domestic ones by 0.4%. both due to a smaller amount of weight loss (6.3% vs. 6.4%) and losses from diseases (1.6% vs. 1.9%). The persistence of carrot root crops is directly correlated with the content of dry matter (r=+0.41), carotenoids (r=+0.39), monosaccharides (r=+0.30) and the amount of sugars (r=+0.27). The manifestation of gray rot is in inverse correlation with the content of dry matter and carotenoids (r=-0.37 and r=-0.35, respectively), white scab is in direct correlation with the content of dry matter (r= +0.21; r= +0.39; r= –0.41, respectively), white rot is in inverse correlation with the content of dry matter, monosaccharides and disaccharides.
