The purpose of the current study was to determine the correlation between adaptability parameters of the spring barley varieties and grain productivity and the main indicators of its quality. The study was conducted from 2011 to 2019 in the conditions of the southern forest-steppe of Western Siberia. The protein percentage in grain, raw oil, starch and husk content of grain were determined according to the Pleshkov and Berkutova methods. The mathematical processing was carried out according to the methodology of Dospekhov, Eberhard and Russell. According to the trial, low productivity of spring barley was recorded in 2012, 2013 and 2016 (2.36–2.92 t/ha) with low values of the index of environmental conditions (-1.32; -1.88). Higher productivity was recorded in 2011, 2015, 2018 and 2019 (5.26-5.89 t/ha), with high values of the index of environmental conditions (1.02–1.65). The productivity of the standard variety ‘Omskiy 95’ varied from 2.11 t/ha (in 2016) to 5.91 t/ha (in 2015). The varieties ‘Sibirskiy Avangard’, ‘Sasha’, ‘Omskiy 100’ exceeded the standard variety (+0.47; +1.97 t/ha to standard). An increased content of raw oil in grain was recorded in the varieties ‘Omskiy 9’1 and ‘Sasha’ (0.4-0.6% to standard). The varieties ‘Omskiy 91’, ‘Sibirskiy Avangard’, ‘Omskiy 90’, ‘Omskiy 96’ and ‘Omskiy 100’ were characterized by a reduced husk content of grain (-0.7; -1.4% to standard). The barley varieties ‘Sibirskiy Avangard’ and ‘Sasha’ (bi > 1; σ2 d < 1) were highly responsive and stable to improving environmental conditions. The improvement of adaptability (bi) of barley varieties did not have a significant effect on grain productivity and quality (r = 0.109±0.020 and 0.232±0.035). The stability (σ2 d) of the varieties was characterized by an average direct correlation with starch content in grain (r = 0.429±0.120), a strong direct correlation with oil content in grain (r = 0.656±0.105). There was identified an average inverse correlation between stability (σ2 d) and protein and husk content in grain (r = -0.399±0.060 and -0.447±0.055). There was a weak correlation with productivity (r = -0.204±0.040).

The article analyzes the current state and improvement of elements of the technology of growing valuable forage and food crops, spring barley in Ukraine. It is noted that in recent years the area under large crops and the yield of this crop have decreased significantly. It is emphasized that further improvement of technologies should be focused on the transition to more use of biological agents to increase yields. Researchers have shown that the effectiveness of the use of humid preparations GK-6M, GK-4MK, GK-MK - on crops of spring barley Dokuchaivsky 15, due to foliar feeding of plants in the tiller ring phase. The main justification of the article is the results of field research conducted in 2015–2019. Maximum indicators, namely: increase in leaf area by 46–38 %, stem height by 8,3 cm; the number of grains in the ear – 4,8 pieces; ear lengths – 1,9 cm; mass of grain in the ear – 0,33 g; masses of 1000 grains – at 12,0 %; nature of grain – 34,9 g – was obtained by treating plants with humid preparation GK-6M. Foliar feeding of plants in the tiller ring phase with the studied drugs provided the largest increase in the yield of spring barley grain – 1,08 t/ha, provided the use of growth stimulant GK-6M. A slightly smaller effect of foliar fertilization of plants on the yield of spring barley was observed from the growth stimulator GK-4MK – the increase in grain yield was 0,83 t/ha and from the growth stimulant GK-MK – the increase in grain yield – 0,66 t/ha. The obtained increments are significant, mathematically proven. Further improvement of agrotechnologies due to wider use of biological means of increase of productivity and quality of production is offered. Keywords: spring barley, plant growth stimulants, foliar feeding, yield.

The Impact

Theresearch results are presented conducted during 2016-2018 on southern chernozem with two varieties of spring barley to study the impact of nutrition optimization on grain yield and elements of its structure. It is determined that the treatment of crops with growth regulating drugs in the main growing seasons provides a significant increase in grain productivity of barley, which is the highest when formed by three foliar nutrition with modern growth regulating drugs in the tillering phase and plant emergence in the tube at the beginning of earing. The grain yield of spring barley of the Stalker variety increased on average over three years, depending on the growth regulator taken for processing, in the range of 3.25 – 3.60 t / ha at its level in control, respectively, for treatment of plants with water 2.50 t / ha, and the variety Vakula – to 3.41 – 3.71 compared with 2.47 t / ha in the control. It was found that the increase in grain yield by the studied varieties of spring barley was due to the increase in ear length, and most significantly – due to more grains in the ear, the weight of grain from the ear and the weight of 1000 grains. These indicators increased and changed under the influence of power optimization. Key words: spring barley, varieties, elements of crop structure, grain yield, foliar fertilization, growth regulators.

Abstract The purpose of the research is to study the effect of the fungicide Lamador and the humic preparation Rostok on the quality of spring wheat and spring barley in the conditions of the northern forest-steppe of the Tyumen region. According to the yield, we found that pre-sowing seeds treatment with Lamador protectant and joint treatment with Rostock contributed to an increase in yield by 0.70 t/ha of spring wheat and 0.15 t/ha of spring barley, in the option with the pre-sowing seeds treatment with Lamador protectant and Rostock preparation by 0.90 t/ha and 0.10 t/ha. The highest yield of spring wheat was noted in the third option – 4.10 t/ha, of spring barley in the second option – 3.52 t/ha. An increase in the thousand kernel weight was noted in the crops under study. The highest thousand kernel weight was observed for spring wheat and spring barley in the third option – 30.2 g and 54.3 g, respectively. The maximum protein content in the spring wheat grain was noted in the third option –13.3%, which is higher than the control option by 1.3%, for spring barley we also noted protein increase by 0.4-0.5%. Thus, the experimental application of the fungicide Lamador together with the preparation Rostok for wheat seeds treatment demonstrated a positive effect of the protectants on plants in the agro-climatic conditions of the forest-steppe zone of the Tyumen region and contributed to an increase in crop yield by 28% for spring wheat and 4% for spring barley, which proved the need for their use in the plant protection system, to increase the productivity and quality of the grain obtained.

The general climate change in the south of Russia makes the development of new varieties of grain crops, including forage grasses, with high resistance and adaptability to climatic stress factors extremely necessary. The breeding process of forage plant adapted to changing environmental conditions is seen as an effective way to allow crop production to cope with unexpected possible climate changes with the least possible losses. The specific reaction of plants to environmental conditions is of particular interest when studying collection plant samples of different gen[1]otypes, as well as when choosing varieties for cultivation in specific conditions. Studying the stability and adaptability of collection samples of forage grasses can also make it possible to use them in different regions. The purpose of the current study was to estimate alfalfa samples by the parameters of ecological adaptability and stability according to the trait ‘seed productivity’. The objects of study were 30 samples of the VIR collection from the USA, Canada, France and Peru. There has been identified a large group of samples with bi < 1. These samples were important as genotypes with a weak responsiveness of seed productivity to worse conditions. They are to be used in hybrids to obtain an initial material that is adaptive according to the trait ‘seed productivity’ in stressful conditions. The smallest bi coefficient was found in the samples ‘K-42694’ (0.20), ‘K-32783’ (0.22) and ‘K-47804’ (0.29). The stability coefficient σd 2 , which reflects the correlation between the growing conditions and seed productivity of the samples through the years of study and was calculated on the basis of the theoretical productivity and the deviation of the theoretical value from the actual one, varied from 0.01 to 74.70. This range of variation indicates that the set of samples contains such samples whose stability of productivity is genetically determined and significantly exceeds the variability of the average productivity of the entire set. Estimation of differences according to stability of seed productivity, in comparison with the standard variety ‘Rostovskaya 90’, revealed a significant difference in this trait in the samples ‘K-43272’, ‘K-50545’, ‘K-50561’.

The total 43 Slovak spring barley genotypes with a year of cultivation or registration from 1938 to 2009 were evaluated in terms of selected parameters like protein, starch, and β-glucan contents. Collection of genetic resources consisted of barley malting qualities such as elite - A, standard quality - B, no malting quality - C and five genotypes of unspecified malting quality. Significant (P < 0.01) influence of genotype and environmental conditions (years) and also genotype × year interaction on protein, starch, and β-glucan content in the barley grain were detected. The highest average protein content was observed in genotypes from the group with undetermined malting quality. The protein and β-glucan contents in older genotypes were higher in comparison with more recent genotypes. The average starch content in both older and modern genotypes in the studied set was nearly identical, which confirms a high quality of the older malting varieties. According to malting quality groups, the highest average value of β-glucan content was in the group of no malting quality (C) and the lowest in the group of best malting quality (A), which is in correspondence with barley malting quality requirements. In individual years differences in the β-glucan content were found among genotypes. Despite the atypical years, good sources of β-glucan were found out along with modern genotypes such as Cyril and older genotypes such as Orbit and Vladan, but also historically old genotypes were created in the year 1946 such as Diosecký 802 and Slovenský Dunajský trh. Our study has confirmed that these genotypes are donors of not only significant agronomic traits but also qualitative properties, usable in the food industry.

In order to maximize the potential of productivity of spring barley varieties, it is important to optimize the conditions for plant growth and development, which are, first of all, provided by the latest intensive agricultural technologies, which provide for the correct placement of crops in crop rotation after the respective precursors; optimal supply of plants with nutrients, taking into account their content in the soil; fractional application of nitrogen fertilizers during the growing season by phases of growth and stages of organogenesis; the use of retardants, integrated protection of plants against weeds, pests, diseases, timely and quality implementation of all agrotechnical measures. Research to study the effectiveness of different terms of spring barley sowing and doses of nitrogen fertilizers were conducted during 2018 - 2019 in the conditions of the research field of VSAU v. Agronomichne of Vinnytsia region on gray ashed soils. Weather conditions during the years of the research differed from the average long-term data with high temperature conditions and low rainfall, and accordingly the most favorable year for the growth and development of spring barley was 2018. It is shown the 2-years investigation results on study the effect of sowing dates and nitrogen fertilizations on productivity elements and quality indexes of spring barley grain under conditions of Right-Bank Forest-Steppe on gray forest soils. Accordingly, the highest levels of harvest of barley cultivars at different sowing dates were obtained under conditions of 2018. t should also be noted that the delay of sowing by 6 days in the years of research leads to a decrease in the yield level on average for all varieties by 0,42 – 0,64 t / ha, and a delay of 14 days leads to a decrease by 1,37 – 1,80 t / ha. The use of nitrogen fertilizers leads to an increase in the yield level of both cultivated varieties, and the highest crop yields of the Svarog variety were obtained in the experiment where the background + N60 was applied in the foliar fertilization (4,87 t / ha), and the lowest respectively in the control variant 3,16 t /ha, in the Armax variety a similar situation is observed, however, with lower indicators respectively 4,54 and 3,06 t / ha. The lowest values of protein content in the grain were obtained in the control variant where only N17 P17 K17 was applied to rows when sowing, and the use of nitrogen fertilization leads to an increase in this indicator and the highest values obtained in the variant of experiment 4, where Background (N17 P17 K17) + N60 in the foliar fertilization on the feeding phase of the tube exit. Key words: spring barley, nitrogen fertilizers, elements of the crop structure, yield, quality of production.

The article presents the results of spring barley crops and the effect of foliar fertilization on them. Prospects and effectiveness of biological products as a basic fertilizer for cereals. Spring barley is a valuable food, fodder and technical crop. Pearl barley and barley groats are made from vitreous and coarse-grained two-row barley grain. Most barley is used for feed purposes. In 1 kg. grain contains 1.2 feed units and 100 g of digestible protein. Spring barley contains a lot of protein (9-12%), carbohydrates (70-75%), pentazoles (7-11%), sucrose (1.7-2%), fiber (3.8-5.5%), fat (1.6-2%), ash (2-3%). Spring barley grain is characterized by high nutritional value and is widely used in feed production, confectionery, brewing. However, in the dynamics of its yield there are significant fluctuations, which is associated with both agro-climatic conditions and organizational and economic. Having a short growing season, underdeveloped root system, the culture is quite demanding on the provision of basic factors of plant life, including nutrients. The system of fertilization of spring barley is determined primarily by predecessors. It has a valuable ability to make the best use of the aftereffects of organic and mineral fertilizers applied to the previous crop. If spring barley is sown after well-fertilized row crops (sugar beet, potatoes), under which 40-50 t / ha of manure and mineral fertilizers are applied within N80P80K80 - N120P120K120, then fertilizers are not applied directly under barley at all. Against this background, barley with proper care can form 40-50 kg / ha of grain. It is clear that in case of incomplete supply of sugar beets or potatoes with fertilizers, barley will require additional application of macronutrients. Barley responds very well to fertilizer application, especially in conditions of sufficient moisture. The increase in yield from mineral fertilizers can reach 15-20 kg / ha. To prevent lodging of plants, it is necessary to ensure the correct ratio of nutrients - nitrogen, phosphorus and potassium. Given the condition of the soil cover and low volumes of fertilizer application, we consider the issues of optimization of mineral nutrition of spring barley to be relevant and in need of refinement. An important component of the plant nutrition system is the use of microfertilizers. Therefore, the purpose of our research is to establish the reaction of spring barley to the complex use of microfertilizers, crop formation and grain quality in the conditions of the Right-Bank Forest-Steppe of Ukraine [3] Key words: spring barley, foliar feeding, biological products.

In recent decades, the demand for naked barley grain on the market has increased, that is why the breeders of the leading institutions of the Russian Federation resumed breeding research to develop new naked barley varieties. In this regard, the purpose of the current study was to develop a breeding material for naked spring barley, adapted to the conditions of the Rostov region and, on its basis, new varieties. There have been developed the new naked barley variety with high productivity and grain quality, adapted to the conditions of the North Caucasus. The study was carried out in the scientific crop rotation of the department of barley breeding and seed production of the FSBSI Agricultural Research Center “Donskoy” (Zernograd) in 2014–2020. Based on the best local spring barley varieties (‘Leon’ and ‘Shchedry’) and naked varieties of the VIR collection (‘Mancuria’ (Sweden), ‘NB-OWA’ (Nepal), ‘CDC-Dawn’ (Canada), ‘K-3780’ (Tajikistan) and ‘Golozerny’ (RF)) there have been developed and studied the new naked barley lines. There was found that according to the trait ‘plant height’ the lines ‘Leon x Golozerny’ and ‘Leon x Mancuria’ belonged to the middle-height group (90.2 cm and 83.4 cm, respectively). The rest of the lines belonged to the tall group, their height varied from 96.5 cm to 100.3 cm. According to the trait ‘earing date’ there has been identified the line ‘Leon x Golozerny’ (24V), which is more early-ripening (5 days less than that of the standard). The same line turned out to be the only one that significantly exceeded the standard (the standard variety ‘Ratnik’ on 4.5 t/ha) according to productivity +0.3 t / ha, and taking into account the absence of hulls, this difference significantly increased to +0.7 t/ha. There was established that according to the trait ‘1000-grain weight’, the lines ‘Leon x Mancuria’, ‘Leon x CDC-Dawn’, ‘Leon x K-3780’ and ‘Leon x Golozerny’ significantly exceeded the standard variety. The best indicators of grain quality were identified for the lines ‘Leon x K-3780’ and ‘Leon x Golozerny’. The lines ‘Leon x Mancuria’ and ‘Leon x Golozerny’ were the most resistant to powdery mildew. The current paper has presented the characteristics of the new naked spring barley variety ‘Zernogradsky 1717’, which has a great productivity and a set of positive economically valuable traits.
