Scientifically substantiated application the elements of technologies with the use of microbiological preparations, macro- and microfertilizers, new growth regulators of plants of organic origin, allows not only to increase grain yields, improve its quality, but also to affect the economic efficiency of spring barley cultivation. Today, biological, growth stimulants are widely used in various types of agricultural crops. They are an effective method of achieving increased productivity, increasing resistance to diseases and pests, which, in turn, makes them attractive to researchers. The introduction of biologically active substances in agricultural practice is impossible without a deep and comprehensive study of their effect on the growth and development of the plant, as it depends on the type of preparation, rate, processing time, varietal characteristics of the crop, and other factors. The aim of our research was to evaluate the effect of biopreparation of phosphorus mobilizing action and foliar fertilization with macro- and microfertilizers on the formation of spring barley productivity at sowing after predecessors of soybean, winter wheat, sunflower, and corn for grain in conditions of unstable soil moisture in Steppe zone. Due to significant fluctuations in weather conditions during the growing season of spring barley, by the bree­ding of ecologically adapted varieties, predecessors and using elements of technology that involve the seed treatment with biopreparations and foliar fertilization in the tillering phase of plants, one can consistently obtain grain yields at 4.32−5.23 t/ha. Improving the nutrient regime of the soil with the use of the preparation Polymyxobacterin based on the growth-stimulating bacterium Paenibacillus polimyxa KB contributed to the improvement of plant nutrition and increased the crop yield of spring barley by 0.17−0.65 t/ha depending on the predecessor. The increase in grain yield of spring barley from the use of foliar fertilizers with macro-and microfertilizers was 0.29−0.41 t/ha. The highest level of grain yield (5.68 and 5.18 t/ha) when sowing spring barley variety Statok after predecessors soybean and sunflower obtained in the trial of inoculation with phosphorus mobilizing preparation Polymyxobacterin and fertilization in the tillering phase with micro-fertilizer Reakom, after grain crops – 5.19 t/ha Polymyxobacterin + CAM 28, N8, after corn for grain – 4.92 t/ha, Polymyxobacterin + Urea, N8. The increase compared to control was 0.83 t/ha, 0.95; 0.83 and 1.25 t/ha respectively, by predecessors. The use of biopreparations based on effective microorganisms should be an integral aspect of modern agriculture, taking into account climate changes. The practical value of using biological preparations for seed inoculation before sowing in combination with foliar fertilization of macro- and microfertilizers in the period of formation of the generative organs is due not only to their efficiency but also the low cost of their use, which is an element of resource-saving technologies and eliminates environmental pollution.

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.

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.

Evaluation and Use of Genetic Resources in Spring Malting Barley Breeding in Lithuania During the period 2004-2006, grain yield stability and malt quality characteristics of 47 spring barley varieties and 55 promising breeding lines from the collection of spring barley genetic resources were investigated at the Lithuanian Institute of Agriculture (LIA). The growing conditions in 2004 were fairly normal compared with the long-term mean, and the years 2005 and 2006 were rather dry. The varieties and breeding lines tested showed from medium to high variation of grain > 2.5 mm yield (CV 11.5-34.3%) and medium variation of grain yield (CV 4.39-13.33%). However, high temperatures and drought in June of 2006 caused a low grain > 2.5 mm yield (by on average 55.0-67.8%). Promising breeding lines were characterised as having higher grain yield and extract output per ha compared with barley varieties. However, the data showed that grain grading 2.5 mm should be improved for the breeding lines. Using the software STABLE we estimated the stability of malting barley quality traits in relation to weather conditions during the crop year, genotype properties for varieties and breeding lines, as well as the interactions of variety and weather conditions. The selection of lines promising in terms of grain yield, > 2.5 mm grain yield and extract yield, was based on their ability to realise the genetic potential in various growing conditions. The highest score in integral assessment of grain yield, grain > 2.5 mm yield and extract yield was identified for the varieties Tocada', Sebastian', Scarlett' and breeding lines: 7939-1, 7661-1, and 8080-4. The varieties and breeding lines that exhibited high grain stability, high grain quality and other agronomic traits were utilised in further breeding programmes.

Stem Reserves

SUMMARYPre-anthesis stem reserve contribution to grain yield was assessed in two spring barley cultivars of contrasting height. It was greatest in the taller, but final grain yields were similar. Partitioning of total reserve capacity to various plant parts showed that the leaf and sheath below the peduncle were most important, followed by stem internodes which had increasing reserve capacity up to internode 4.It is suggested that stem reserves are valuable for yields commonly achieved in U.K. commercial practice.High grain yields were associated with large positive increases in stem dry weight after anthesis. This would indicate that the source capacity to boost yield is more than proportional to that required to fill the grain alone.

SUMMARYExperiments with spring barley at Saxmundham, in each year from 1975 to 1978, compared two varieties (Julia v Wing), two amounts of granular N-fertilizer (50 v 100kg N/ha) and two times of applying it (seed bed v top-dressing), a liquid N-fertilizer spray (0 v 50 kg N/ha), mildew fungicides (with and without) and a rust fungicide (with and without), in factorial combination (26).Leaf diseases were assessed and grain weighed and analysed for % N each year. Thousand-grain weights were measured in 1977 and 1978.Yields were small in 1975 and 1976 because little rain fell in summer, but larger in 1977 and 1978, years with average rainfall.Mildew was most severe in 1975 and least in 1978, brown rust most severe in 1975 and 1978 and practically absent in 1976. Granular N-fertilizer was best applied to the seed bed in all years, whether or not leaf diseases were controlled. Late sprays of liquid N-fertilizer increased yield less than equivalent amounts of seed-bed N, but increased % N in grain more. However, because they also decreased grain size, less of the N applied as a liquid was recovered by grain than was recovered from granules given earlier. The mildew fungicides increased yields by ca. 0·25 t/ha in 1975 and 1977, but decreased them in 1976. They had little or no effect on % N in grain, but increased grain size in 1977. The rust fungicide, benodanil, increased grain yields each year and especially in 1978 (0·37 t/ha). It had no effect on grain % N, but consistently increased grain size and so enhanced grain yield and N uptake.

The Cost

The results of research conducted in 2016‒2018 on the southern chernozem andthe effect of two varieties of spring barley extra-root feed on the formation of grain productivityare given. Based on the results obtained, indicators of agroeconomic efficiency and their changewere determined under the influence of this event (as one of the most important elements of technology)in growing the crop, including in terms of varieties. Despite the increase in productioncosts, the treatment of plant seeding with biologics contributed to a certain increase in notional netprofit, which increased with the number of feeds, reaching the highest values if used to optimizethe nutrition of Fresh florid (300 g/ha). One feeding of Stalker variety is determined at the levelof 5927, two feeding ‒ 6890, three ‒ 7320 UAH, and 3857 UAH/ha ‒ in control. The mentionedindicators were 5968, 6808, 7771 and 3980 UAH/ha, respectively, when the spring barley varietyVakula was grown. One of the most important indicators of economic efficiency decreased‒ the cost of growing a unit of production with an increase in the number of extracurricular feeding.The lowest indicator was the cost price of production of top – dressing with Fresh florid(300 g/ha ‒ according to the Stalker variety): with one extracorporeal sowing ‒ 2269.4; two treatments‒ 2173.5, and three ‒ 2166.7 UAH/t; in control, this indicator was 2638.5 UAH/t. Thesevalues were, respectively, 2262.3; 2185,8; 2105.4 and 2608.0 UAH/t when the barley spring varietyVakula was growing. The use of other biological preparations led to a certain increase in thecost of growing spring barley. The highest values were recorded when using Organic D-2 M withonly one feeding in the plant phase. In this version of the experiment the cost of growing a unitof production even slightly exceeded control, when Vakula variety was grown. The cultivation ofspring barley on the basis of resource saving using modern re-regulating substances and biologicalpreparations is advisable, because it increases not only the level of grain yield, but also themain indicators of agro-economic efficiency - net profit and profitability, and unit cost, on thecontrary, decreases. It was established that by optimizing the nutrition of spring barley on thebasis of resource saving by treating crops in the main growing seasons with biological products,along with increasing grain yield and changes in its quality, other indicators of agro-economicefficiency of crop production increase. The level of profitability in control (treatment of plantswith water) for the cultivation of barley of the spring variety Stalker was 59.2%, then in themost optimal food options it reached 93.8%, and for the Vakula variety they were determined61.0 and 99.5% respectively. The obtained agroeconomic indicators in the cultivation of springbarley made it possible to substantiate the following claims: the use of biologics to treat thesowing of spring barley plants during the main periods of vegetation increases the yield and costof grown grain. It was determined that the level of profitability of growing spring barley witha large number of feeds grew. The indicator reached its maximum value with three times theplanting of barley plants of the spring variety Vakula with Fresh florid, that is, 300 g/ha (99.5%).Two plant crops with this drug provided profitability at the level of 99.1%, and one ‒ 85.6, (incontrol ‒ 61.0%). The highest profitability of cultivation was ensured by the use of Fresh florid(300 g/ha) for optimizing nutrition three times for vegetation ‒in the phases of tillering, shootingand heading. The lowest level of profitability was ensured by the use of the preparation OrganicD-2 M for feeding barley of the spring variety Vakula: one treatment of plants ‒ at the level of60.6%, two ‒ 72.5, three treatments ‒ 78.2%. According to the results of research conductedwith two varieties of spring barley, the best biological product and terms of fertilization weredetermined in order to increase grain yield and improve its quality and agro-economic efficiencybased on the calculation of cost economic indicators. The expediency of nutrition optimizationby using modern biological products for spring barley cultivation has been confirmed.

In small-plot experiments established in 2001–2004 we studied the effect of the chemical composition of the plant dry matter of spring barley, varieties Kompakt and Jersey, on grain yields. A re­la­ti­ve­ly strong correlation was confirmed between the chemical composition of the plant dry matter and yields. The correlation was most intensive in the case of nitrogen (r = 0.536), phosphorus (r = 0.503), magnesium (r = 0.464) and sulphur (r = 0.431) at the beginning of shooting (DC 30); in the case of potassium (r = 0.557) at the beginning of tillering (DC 23) and calcium (r = 0.530) during ear formation (DC 55). A relatively strong correlation remained from the beginning of tillering to the beginning of ear formation and later decreased. The weather conditions of the year and variety significantly affected grain yields and also the previous crop was important. Grain yields of the variety Kompakt were statistically significantly lower than of the variety Jersey (6.02 t . ha−1 and 6.45 t . ha−1, respectively). The yields of barley grown after sugar-beet were the highest (6.30–6.79 t . ha−1); the grain yields of barley after maize decreased by 9.1–9.7 %. Higher grain yields of the Jersey variety resulted in levels of ­N-substances (11.35 %) lower than in the Kompakt variety (11.35 % and 11.60 %, resp.). No correlation was discovered between the nitrogen level in the plant dry matter during vegetation and the content of ­N-substances in barley grain.

SummaryThree experiments were carried out in which nitrogen was applied to spring barley (cv. Midas) either all in the seed bed or as a divided dressing with 10 or 25 kg/ha in the seed bed and 50 or 60 kg applied at emergence or 10, 20, 30, 40, 50, 60 or 70 days after emergence. Applying part of the nitrogen as a top dressing up to 30 days after emergence and 50 days after emergence had no significant effects on the grain and straw yields respectively, compared with applying all the nitrogen in the seed bed. Grain yields were progressively reduced with top dressings from 40 days after emergence (first node stage) onwards. Applications at 60 or 70 days did not give more grain yield than the no-nitrogen control, but gave straw yields which were intermediate between the no-nitrogen and seed-bed nitrogen treatments. Top dressing at 40 days after emergence stimulated tiller survival but did not improve grain yield because there were fewer grains per ear. Thousand-grain weights were lowest with top dressings at 50 days after emergence and grain nitrogen increased progressively with delay in top dressings from 30 days after emergence onwards.

SummaryIn experiments over 3 years (1974–6) cow slurry in the range 0–112·5 t/ha and ammonium nitrate in the range 0–120 kg N/ha were applied to field plots factorially to test the effects on the yield and quality of spring barley grain.In 1974 slurry application markedly improved the grain yield (cv. Golden Promise) at each rate of inorganic N and increased grain size. Applying N fertilizer with more than 37·5 t slurry/ha reduced grain yield below the maximum. Grain with the highest crude protein content (15·1 %) was obtained from a combination of slurry and inorganic N. The residual effects of the slurry treatments gave satisfactory grain yields in 1975 without additional fertilizer.Grain yields (cvs Julia and Abacus) in other experiments carried out on a different soil type in 1975 and 1976 were approximately half those obtained in 1974, due in part to drought conditions. The pattern of the results was similar. Heaviest grain yields were harvested from plots receiving 70 t slurry/ha with no additional N.

The article presents the results of studying the genotypes of peas by a complex of breeding valua-ble traits. The research was carried out in 2014-2021 in accordance with the methodological guidelines of the VIR and the State Commission for Variety Testing of Agricultural Crops. The objects of study are 59 collectible varieties of peas of various morphotypes, the standard is the Krasnoufimsky 93 variety (Sverdlovsk region). The aim of the work was to isolate the genetic sources of peas by a set of traits for further use in the breeding process. The weather conditions during the study period were contrasting, which allowed the most objective assessment of the studied samples. Grain yields ranged from 126 g/m2 (2021 g) to 468 g/m2 (2014 g). As a result of the study, varietal samples were determined that significantly exceeded the standard for grain yield. The highest yield on average for 2014-2021 was obtained from samples Tigra (Germany) – 437 g/m2, Stabil (Austria) – 376 g/m2, Grana (USA) – 353 g/m2, G-21594 (Kirov region) – 340 g/m2, G-24596 – 331 g/m2, etc. Genotypes with high indicators of productivity elements were identified. The maximum value of the number of productive nodes was noted in the Serio variety (USA) – 4.6 pcs., the number of beans – in G-21594 (7.5 pcs.), the number of grains – in the Verkholuzskaya variety (Komi Republic, 32.2 pcs.), productivity – in the Stabil variety (6.6 g). Most of the studied genotypes (78%) had a mass of 1000 seeds 150-250 g. The largest seeds were characterized by sample No. 40 (Bulgaria, weight of 1000 seeds 340 g). It was found that the grain yield, the number of productive nodes, beans and grains per plant differed the most in the studied cultivars, the mass of 1000 seeds varied slightly.
