Abstract Background The drought environment occurs frequently due to the unpredictable future climate change, and drought has a direct negative impact on crops, such as yield reduction. Drought events are random, frequent, and persistent. Molecular breeding can be used to create drought-tolerant food crops, but the safety of genetically modified (GM) plants must be demonstrated before they can be adopted. In this research, the environmental risk of drought-tolerant GM rice was explored by assessing phenotype and gene flow. Drought resistance genes CaMsrB2 inserted HV8 and HV23 were used as GM rice to analyze the possibility of various agricultural traits and gene flow along with non-GM rice. Results When the traits 1000-grain weight, grain length/width, and yield, were compared with GM rice and non-GM rice, all agricultural traits of GM rice and non-GM rice were the same. In addition, when the germination rate, viviparous germination rate, pulling strength, and bending strength were compared to analyze the possibility of weediness, all characteristic values of GM rice and non-GM rice were the same. Protein, amylose, and moisture, the major nutritional elements of rice, were also the same. Conclusions The results of this research are that GM rice and non-GM rice were the same in all major agricultural traits except for the newly assigned characteristics, and no gene mobility occurred. Therefore, GM rice can be used as a means to solve the food problem in response to the unpredictable era of climate change in the future.

ABSTRACT Seed size is an important indicator of physiological quality, since it may affect seed germination and seedling growth, especially under stress conditions. This study aimed to investigate the effects of seed size on germination and initial seedling growth, under salinity and water stress conditions. The treatments were arranged in a completely randomized design, in a 3 × 3 factorial scheme: three seed size classes (small, medium and large) and three stress treatments (control, saline or water stress), with four replicates. Water and salt stresses do not reduce the germination rate of medium and large seeds; however, the germination rate of small seeds is reduced under salt stress conditions. Drought stress drastically reduces the shoot growth of seedlings regardless of seed size, whereas root growth is higher in seedlings from medium and large seeds under water stress conditions. Under non-stressful environments, the use of large seeds is preferable, resulting in more vigorous seedlings with a greater dry matter accumulation. Medium-size seeds are more adapted to adverse environmental conditions and, therefore, should be used under conditions of water shortage and salt excess in the soil at sowing time. Seedlings are more tolerant to salinity than to water stress during the germination stage and initial growth under laboratory conditions.

The feasibility of a color machine vision technique with the one-class classification method was investigated for the quality assessment of tomato seeds. The health of seeds is an important quality factor that affects their germination rate, which may be affected by seed contamination. Hence, segregation of healthy seeds from diseased and infected seeds, along with foreign materials and broken seeds, is important to improve the final yield. In this study, a custom-built machine vision system containing a color camera with a white light emitting diode (LED) light source was adopted for image acquisition. The one-class classification method was used to identify healthy seeds after extracting the features of the samples. A significant difference was observed between the features of healthy and infected seeds, and foreign materials, implying a certain threshold. The results indicated that tomato seeds can be classified with an accuracy exceeding 97%. The infected tomato seeds indicated a lower germination rate (<10%) compared to healthy seeds, as confirmed by the organic growing media germination test. Thus, identification through image analysis and rapid measurement were observed as useful in discriminating between the quality of tomato seeds in real time.

The article discusses the effect of presowing seed treatment by growth regulators and fungicides on the field germination of seeds of two grades of zinnia elegant – Dream and Orange King. Varieties differed in seed germination time. On average, over three years, Zinnia Dream seeds germinated 0.5–1.0 days earlier than Orange King seeds. The treatment of zinnia seeds with an epin-extra growth regulator contributed to the emergence of earlier seedlings. When the seeds were soaked with a solution of this preparation, the plants went through the sprouting phase faster – the period when they are most sensitive to abiotic stresses. Zircon had a weaker effect on the germination rate of zinnia seeds than epin-extra, however, the presence of a prolonged action of this drug in the activation of non-specific resistance of plants to stress factors can also be noted. The one-component disinfectant benorad turned out to be the most passive and did not significantly affect the germination of zinnia. There were no visible signs of manifestation of pathogens in the juvenile period of plants, and its active substance (benomyl) could hardly affect the rate of emergence of seedlings. In contrast to benorad, the two-component protectant vial TrasT had a weak positive effect on the rate of emergence of seedlings, since it included specially introduced anti-stress components.

Abstract. The authors present the results of the application of complex organo-mineral fertilizer “Bioklad” on mixed sowing of oats with peas in the conditions of the forest-steppe zone Republic of North Ossetia-Alania. The purpose of the work is to study the effectiveness of the use of the organomineral fertilizer “Bioklad” on the yield and nutrition of mixed sowing of oats with peas in the conditions of the forest-steppe zone Republic of North Ossetia-Alania. Methods. Studies on the tasks were carried out in 2016–2018 at the experimental site of the North Caucasus Research Institute of Mountain and Foothill Agriculture – branch of the Federal Center “Vladikavkaz Scientific Center of the Russian Academy of Sciences” in the conditions of the forest-steppe zone Republic of North Ossetia-Alania according to generally accepted methods. The soil of the experimental plot is medium-power heavy loamy leached chernozem, lined with pebbles. Results. The use of fertilizer “Bioklad” had a significant impact on the timing, fullness of shoots and the density of standing plants up to harvest. The field germination rate for peas varied between 70,5 and 72,4 %, while the oat rate was 76,4 to 80 %. The option with seed inoculation was highlighted. According to the dynamics of the height of the plants also stood out the option with the inoculation of seeds. The use of complex fertilizer “Bioklad” had a positive effect on the yield and quality of the green mass of oats with peas. The largest amount of phytomass was obtained under the variant with inoculation of seeds – 283,3 c/ha, which is higher than the control version at 68,3 c/ha. In terms of the content of digestible protein, the harvest of the mixture of oats with peas exceeded the zootechnical norm, the yield from one hectare reached 6,0–6,9 c/ha, against 5,2 c/ha in control, which per feed unit was 113,7–119,9 g. The collection of feed units amounted to 50,02–60,68 kg/ha, and in the control 44,23 kg/ha, feed protein units, respectively: 55,01–64,84 kg/ha; 48,12 kg/ha. Scientific novelty. For the first time in the conditions of the forest-steppe zone Republic of North Ossetia-Alania studied the effect of complex organomineral fertilizer “Bioklad” on plant growth processes, formation of green mass, quality of products in a two-component mixture (oats + peas).

The data of long-term research aimed at improving the forage reserve in order to provide livestock with high-grade concentrated green fodder and silage are presented. The necessity of selection and comparative assessment of maize hybrids of different early maturity and improvement of the basic methods of cultivation technology has been substantiated. The seeding rates slightly changed the field germination rate. On average for 2017–2019 at a seeding rate of 50 thousand seeds per 1 hectare by the panicle-sweeping phase, the leaf surface of the mid-early hybrid Rainbow was 31.2 thousand m2/ha, which is 9.5% higher compared to the early-ripening hybrid Mashuk 185 MV ( 28.5 thousand m2/ha) and 14.3% higher compared to the ultra-early hybrid RNIISK-1 (27.3 thousand m2/ha). With an increase in the seeding rate over 50 thousand seeds per hectare, the leaf surface of all hybrids increased and was maximum at 70 thousand seeds per hectare. The minimum leaf area was at a seeding rate of 40 thousand seeds per hectare. Similarly to the formation of the leaf surface, the accumulation of green and dry biomass took place depending on the seeding rate in the ultra-early maize hybrid RNIISK-1. In the early-maturing hybrid Mashuk 185 MV and the mid-early hybrid Raduga, the accumulation of green and dry biomass did not depend on the seeding rate. Such features of the growth and development of maize hybrids, depending on the seeding rate, influenced the structure and size of the grain yield.

Sorghum is one of the most important crops in all arid tropical and subtropical regions of Africa, Asia, and Central America. In the Russian Federation, the sowing area of sorghum varied from 8.7 to 228.6 thousand ha throughout about 20 years (1999–2018). The main share (93–98%) of the sowing area of sorghum in Russia is located in the Pre-Volga region and the Southern Federal District. The Rostov Region as a part of the Southern Federal District accounts for up to 46–69% of sorghum crops (Kovtunov, 2018). The most effective way to increase productivity and product quality is to create new varieties adapted to the soil and climatic conditions of cultivation and introduce them into agricultural production. The FSBSI “Agricultural Research Center “Donskoy” developed the white-kernelled sorghum varieties “Velikan”, “Zernogradskoye 88” and “Ataman” with 5.41–5.85 t/ha of productivity not only for fodder, but also for food (starch, alcohol). The sweet sorghum varieties “Listvenit”, “Yuzhnoye” and “Feniks” with green mass productivity of 38–46 t/ha are intended for use on green fodder and silage and are characterized by intensive initial growth, lodging resistance, drought resistance, resistance to dust smut, bacteriosis and to cereal aphids. The Sudan grass varieties “Anastasiya”, “Alisa” and “Gratsiaya” developed in the Agricultural Research Center “Donskoy” are characterized by the intensive initial growth and regrowth. They are middle-ripening, drought tolerant, highly productive with 41–44 t/ha of green mass and 8.3–8.6 t/ha of dry matter. There have been developed and are being tested the promising sorghum-Sudan hybrids with 62–77 t/ha of green mass and 11.4–16.6 t/ha of dry matter obtained in mowing the aftermath.

Abstract. The technology of green fodder production is especially important in arid and semiarid regions. Hydroponics improves on average the amount of crops in the same space, as traditional soil-based farming and can reduce water consumption compared to traditional farming methods. Limited research has been carried out on the use of hydroponic fodder and milk quality. A comparative study of traditional (Malta farm) and hydroponic fodder (Gozo farm) was conducted in Malta with 20 cows of the Holstein–Friesian breed from two farms. Individual and bulk-tank milk samples were collected once a week for a period of 1 month in order to evaluate physical (pH, conductivity, density, freezing point) and chemical (fat, protein, ash, lactose, solid nonfat) parameters as well as mineral (Zn, Cu, Pb, Ba) content. Milk proximate and physical data were processed by analysis of variance (ANOVA) for repeated measures and an ANOVA procedure with farm and time as effects for minerals. The results indicated differences in fat content and pH, showing higher values (P<0.05) in milk samples of cows fed with the hydroponic rather than the traditional fodder; a significant time effect (P<0.001) was found in all qualitative analyses except for lactose and salts. Minerals were in the range as reported elsewhere; Cu and Pb content was significantly higher (P<0.001) in the Gozo farm than the one in Malta, whereas Zn content showed higher values in Malta (P<0.001) than Gozo. Although the proximate results were similar for both farms, except for the higher fat content for the Gozo farm, principal component analysis (PCA) revealed that milk quality for the Gozo farm was superior to that of the Malta farm. However, further studies are needed to determine the effects of different hydroponic fodder using a large herd size.

Исследования проведены в 2015–2020 годах на опытном участке ФГБНУ «АНЦ «Донской», расположенном в зоне неустойчивого увлажнения в Зерноградском районе Ростовской области. Так как в последние годы в летний период здесь наблюдается сильная засуха, высокие температуры и неравномерное распределение осадков, многие культуры не способны обеспечить необходимое количество кормов. Поэтому возрос интерес к суданской траве. Данная культура является одной из самых засухоустойчивых, жаростойких, солевыносливых. По содержанию питательных веществ зелёная масса суданской травы не уступает однолетним кормовым культурам, содержит большое количество жира, клетчатки, БЭВ. В ФГБНУ «АНЦ «Донской» созданы и внесены в Государственный реестр селекционных достижений два сорта: Алиса (2019 год) и Грация (2020 год). Сорта допущены к использованию в Северо-Кавказском, Нижне-Волжском и Центрально-Чернозёмном регионах России, могут использоваться для возделывания на зелёный корм и сено. Цель данной работы — оценить морфологические, биологические и урожайные свойства новых сортов суданской травы Алиса и Грация, выделить их особенности и преимущества перед стандартом. Исследования проводились в трёхпольном севообороте. Предшественник — озимая пшеница. Установлено, что новые сорта характеризуются повышенной интенсивностью начального роста и послеукосного отрастания. Они отличаются высокой устойчивостью к поражению всеми видами головни, слабо поражаются бактериозом. Средняя урожайность составила: зеленой массы — 36 т/га (сорт Алиса) и 37 т/га (сорт Грация), абсолютно сухого вещества — 8,5 и 8,8 т/га соответственно, что превышало стандартный сорт Александрина соответственно на 5–6 и 0,7–1,0 т/га. The investigation was conducted at the Agricultural Research Center “Donskoy” in 2015–2020. The Center is located at the Zernograd district of the Rostov region. Severe drought, high temperature and water deficit significantly reduce productivity of many crops in summer. Therefore, cultivation of Sudan grass gained a lot of attention. This crop is highly resistant to drought, heat and salinity. Its green mass is rich in nutrients, fat, fiber and nitrogen-free extractive substances. The Center bred and registered two varieties: “Alisa” (2019) and “Gratsiya” (2020). Both genotypes are adapted to the North Caucasian, Lower Volga and Central Chernozem regions for green fodder and hay production. The aim was to evaluate morphology, biology and yield of these varieties and identify their benefits over the standard. Plants were cultivated under the three-field crop rotation after winter wheat. “Alisa” and “Gratsiya” showed high growth rate, resistance to various smut and bacterial diseases. “Alisa” produces 36 of green mass and 8.5 t ha-1 of absolutely dry matter on average, “Gratsiya” — 37 and 8.8 t ha-1, respectively, exceeding the standard variety “Aleksandrina” by 5–6 and 0.7–1.0 t ha-1.
