Purpose. Determine the content of heavy metals in the grain of spring barley varieties of different application as affected by the duration of storage.
Methods. In the years 2018–2020, 11 spring barley varieties of different applications were studied: grain ‘Stalker’, ‘Vodohrai’, ‘Vzirets’, ‘Ahrarii’, ‘Shchedryk’; universal ‘Enei’; malting ‘Kozak’, ‘Dokuchaievskyi 15’, ‘Etyket’, ‘Helios’, ‘Sviatohor’. The content of chemical elements in the grain (cadmium, lead, mercury, arsenic, copper, zinc) was determined in the dynamics: immediately after harvest, after 7, 14, 21 and 28 days.
Results. In the studied varieties of spring barley, the lead (Pb) content in the grain varied immediately after threshing and after 7 days ranged from 1.01 to 1.12 mg/kg. Reduction of the studied element after 14 days was observed in all varieties. In particular, the lead content was 1.03 mg/kg in ‘Shchedryk’, 1.01 mg/kg in ‘Stalker’, 1.00 mg/kg in ‘Vzirets’, 0,78 mg/kg (the lowest) in ‘Vodohrai’, and 1.12 mg/kg (the highest) in ‘Ahrarii’. Studies have shown that the most sensitive to cadmium (Cd) grain variety of spring barley was ‘Vzirets’ with the content of 0.09 mg/kg immediately after threshing and on the 7th day of storage; on the 14th, 21st and 28th days, the content was 0.08 mg/kg. The content of cadmium in malting barley grain immediately after threshing and after 7 days was 0.08 mg/kg in ‘Sviatohor’, and 0.09 mg/kg in all other varieties. On the 14th day, the accumulation remained unchanged in varieties ‘Dokuchaievskyi 15’, ‘Etyket’, ‘Helios’, ‘Sviatohor’; insignificant decrease was noted in ‘Kozak’ (0.07 mg/kg). After the storage for 21 and 28 days, the cadmium content was 0.07 mg/kg in ‘Sviatohor’ and ‘Kozak’, and 0.08 mg/kg in all others.
Conclusions. The lowest cadmium content was determined in variety ‘Shchedryk’. Immediately after threshing and after 7 days of storage it was 0.05 mg/kg, and on the 14th, 21st and 28th days it decreased to 0.03 mg/kg. Immediately after threshing and after 7 days, the mercury content of the varieties varied from 0.07 to 0.03 mg/kg. After 14, 21 and 28 days, the following values were determined: in ‘Vodohrai’ 0.06 mg/kg, in ‘Stalker’ and ‘Vzirets’ 0.05 mg/kg, in ‘Ahrarii’ 0.04 mg/kg, ‘Shchedryk’ 0.3 mg/kg. Depending on the varietal characteristics and duration of storage, the highest content (14.05 mg/kg) was determined in ‘Ahrarii’, and the lowest (12.55 mg/kg) in ‘Shchedryk’. The study of the ‘Enei’ variety of spring barley of universal application allows us to note that the accumulation of heavy metals, as affected by the duration of storage, did not differ significantly from the grain varities.

Purpose. Study the formation of yield and grain quality of baking winter wheat of different varieties.
Methods. Laboratory, physico-chemical, mathematical and statistical.
Results. The grain yield of baking winter wheat varied significantly depending on the variety. On average over two years of research, the highest yield (8.12–8.47 t/ha) was obtained in ‘Colonia’, ‘RGT Reform’, ‘Quebec’, ‘Tobak’, ‘Mescal’ and ‘Emile’ varieties. In ‘Bonanza’ and ‘Rivero’ varieties, this indicator was at the level of 7.48–7.53 t/ha. It should be noted that the stability index was high (0.92–0.98) for growing all varieties. In the favourable 2020 year, the grain yield ranged between 7.62 and 8.80 t/ha, while in the less favourable years it ranged between 7.34 and 8.26 t/ha depending on the variety. On average, over two years of research, the protein content of more than 13.0% was formed by ‘Emile’, ‘Bonanza’, ‘RGT Reform’ and ‘Quebec’ varieties, while in other the varieties it was 12.4–12.9%. The studied varieties of baking wheat had a high stability of protein content (0.98–0.99). Baking winter wheat grain had an average gluten content of 27.7–29.7%, depending on the variety, with high stability. Its highest content (29.5–29.7%) was obtained in ‘Emile’, ‘Quebec’ and ‘RGT Reform’ varieties. The gluten content in grain was directly proportional to the protein content. There is a direct very high correlation between these indicators (r = 0.91 ± 0.001). According to the Zeleny sedimentation test results, flour strength was high only in ‘Quebec’ variety, while in the other varieties it was medium. The grain of ‘Quebec’ and ‘RGT Reform’ varieties corresponds to valuable wheat; ‘Rivero’ and ‘Bonanza’ correspond to a good filler, while the rest of the varieties correspond to a satisfactory filler. The grain of ‘Quebec’, ‘Mescal’, ‘Rivero’ and ‘Colonia’ varieties is medium hard as the hardness was 54.1–59.1 units of instrument. Grain of the other varieties is soft with 48.3–51.1 units of instrument. Grain of ‘RGT Reform’, ‘Rivero’, ‘Emile’ and ‘Tobak’ varieties had the largest (794–812 g/l) grain unit. This indicator in the other varieties was at the level of 760–785 g/l. Flour strength is directly proportional to protein content. There is the direct high correlation between these indicators (r = 0.87 ± 0.002). Correlation between the protein content and the sedimentation index by Zeleny test was direct high (r = 0.79 ± 0.001). However, with grain hardness it was inversely weak, and with the grain unit direct moderate (r = 0.35±0.003).
Conclusions. Yield of winter baking wheat varieties was in the range from 7.48 to 8.47 t/ha, protein content varied from 12.4 to 13.8%. Protein content highly correlated with the major baking properties of wheat grain. Baking winter wheat ‘RGT Reform’ and ‘Quebec’ varieties are recommended for stable grain production with good baking properties in the conditions of the Right-Bank Forest-Steppe.

Purpose. To study biological features of biological potential realization of softneck garlic productivity.
Methods. Field, laboratory, statistical and calculation-analytical.
Results. The results of studying local and introduced forms of softneck garlic cultivars (samples No. 1, 14, 16, 19, 24, 27) in comparison with varieties (‘Prometei’ (standard) and ‘Liubasha’) in terms of productivity are presented. In the research, field, laboratory and statistical methods were used. The experimental design was a systemic complete block design without replicates. It was found that all, without exception, softneck garlic cultivars have an erectoid type of leaf placement. Introduced cultivars featured low seedstalk formation, which is a manifestation of adaptation to growing conditions. All studied cultivars were characterized by lower values of the number of air bulbils in the inflorescence compared to the standard cultivar ‘Prometei’. Thus, ‘Liubasha’ formed 16.1% fewer bulbils than the standard; however, its 1000-bulbil weight was 37.2% larger than in ‘Prometei’. The softneck cultivars that formed bulbils on the reduced seedstalk were characterized by a very small number of bulbils − by 89.7–90.8% less than in the standard – however, the formed bulbils had very large 1000-bulbil weight. Thus, sample No. 1 formed bulbils by 542.0% larger in terms of the 1000-bulbil weight than standard; sample No. 16 by 554.3%; sample No. 27 by 752.9%. Samples No. 14, 19 and 24 did not formed seedstalks. In terms of the bulbil yield, the samples that formed bulbils had by 11.7–40.1% lower indicators than the standard. Cultivar ‘Liubasha’ was characterized by a 19.0% higher bulbil yield. The vast majority of collection samples of winter garlic formed smaller bulbs. Sample No. 16 had a large bulb wight compared to the standard. Collection samples had significantly lower yield except for No. 16, which exceeded the standard by 30.2 and 56.8%.
Conclusions. Collection samples have a significantly higher dry matter content. The promising samples (No. 14, 16, 19, 24) were selected by a number of characteristics as promising for further breding of softneck table garlic cultivars. In further research, the content of secondary metabolites and the storage of the samples in uncontrolled conditions will be studied in order to create table garlic cultivars suitable for long-term storage.

Purpose. Determine the formation of physico-chemical quality indicators (berry weight, protein, carbohydrates, fat, dietary fiber, organic acids) of fresh, dried and frozen sea buckthorn fruits of different varieties.
Methods. Laboratory, mathematical and statistical, physicochemical.
Results. The water content in sea buckthorn berries was the highest, but also varied significantly depending on the variety. The varieties of sea buckthorn ‘Haleryt’ and ‘Yelyzaveta’ had the highest content – 90%, by 2 and 3% less in the varieties ‘Burshtynove namysto’ and ‘Altaiska’, in the varieties ‘Sonechko’ and ‘Uliublena’ – 85%. The lowest water content was in the berries of ‘Ryzhyk’, ‘Podruha’, ‘Diuimovochka’, ‘Chechek’ varieties – 75–78%. Dried fruits contained water from 22 to 16%. In the varieties ‘Uliublena’, ‘Yelyzaveta’, ‘Altaiska’ – 22%, ‘Haleryt’, ‘Diuimovochka’, ‘Sonechko’, ‘Burshtynove Namysto’ – 20%, ‘Avhustyna’, ‘Ryzhyk’, ‘Podruha’ – 18%, ‘Veleten’ and ‘Chechek’ – 17 and 16%, respectively. The content of dietary fiber was 4.5–6.2% depending on the variety. The lowest content of dietary fiber was found in the varieties ‘Uliublena’ and ‘Altaiska’ – 4.5–4.7% in fresh and 2.4–2.5% in dried berries. The highest rates were in the varieties ‘Avhustyna’, ‘Sonechko’, ‘Burshtynove Namysto’ in fresh varieties – 6.0, 6.2 and 5.9%, and in dried varieties – 5.5%. The ‘Chechek’ and ‘Veleten’ varieties contained 5.7% in fresh berries and 5.0 and 4.5% in dried berries. The content of fat in fresh berries was in the range of 5.0–5.7%, depending on the variety. In dried berries it increased to 6.0–6.7% or 18–20% depending on the variety of sea buckthorn. In fast-freezing berries, this figure decreased to 4.5–5.2% or 9–10%. The content of organic acids in fresh fruits was the highest – 1.5–2.0%, depending on the sea buckthorn variety. Their content in dried berries decreased to 1.3–1.7% except for the varieties ‘Avhustyna’, ‘Sonechko’ and ‘Burshtynove namysto’, and in the frozen ones to 0.3–0.9%. It should be noted that a similar trend is observed in frozen berries of ‘Avhustyna’, ‘Sonechko’ and ‘Burshtynove namysto’ varieties.
Conclusions. It is established that physicochemical quality indicators of fresh, dried and frozen sea buckthorn berries vary depending on the variety. The varieties ‘Avhustyna’, ‘Sonechko’, ‘Burshtynove Namysto’ have the largest weight of one berry 1.4–1.5 g. 8–6.0%), fat (5.5–5.7%), protein (1.5%), organic acids (2.0%) and dietary fiber (5.9–6.2%) in fresh berries.

Published: December 2021

Background: To describe various measures for estimation of effect size, how it can be calculated and the scenarios in which each measures of effect size can be applied.
Methods: The researchers can display the effect size measures in research articles which evaluate the difference between the means of continuous variables in different groups or the difference in proportions of outcomes in different groups of individuals. When p-value alone is displayed in a research article, without mentioning the effect size, reader may not get the correct pictures regarding the effect or role of independent variable on the outcome variable.
Results: Effect size is a statistical concept that measures the actual difference between the groups or the strength of the relationship between two variables on a numeric scale.
Conclusion: Effect size measures in scientific publications can communicate the actual difference between groups or the estimate of association between the variables, not just if the association or difference is statistically significant. The researchers can make their findings more interpretable, by displaying a suitable measure of effect size. Effect size measure can help the researchers to do meta-analysis by combining the data from multiple research articles.
