Sweet pepper takes one of the main places in the human diet among all vegetable plants. By the content of healthy vitamins, sweet pepper fruits have a better effect on the absorption of food than greenhouse cucumbers and tomatoes, and therefore sweet pepper is in great demand among consumers. The difference in the biometric and physiological parameters of sweet pepper of different age seedlings depends on the duration of growing seedlings. For the study, a sweet pepper variety of domestic selection Aphrodite was used. At the same time, biometric determinations were carried out over the sweet pepper plant: seedling height, stem diameter before planting, plant mass. The observation method monitored the onset of phenological phases of plant growth and development, and a laboratory method was used to determine biometric parameters. The appearance of the first leaf was established with clear control of the microclimate parameters and the provision of an appropriate irrigation regime. The formation of the first leaf was observed on the 7th day after emergence. It was proved that the formation of subsequent leaves, the growth of vegetative mass depended significantly on the age of the seedlings: the higher the seedling age, the more real leaves formed, due to the accumulation of dry matter in the leaves and the corresponding nutritional and temperature conditions. At the time of planting seedlings in open ground, at a constant place of vegetation, the plants were characterized by the presence of 4-6 real leaves, the height of the seedlings was 12-15 cm with a total weight of 10-12 g, there were no damage by pests and diseases on the surface of the leaves. As a result of different age of seedlings, studies have established that with a decrease in the age of seedlings, a tendency to delay flowering and fruiting was observed. The age of seedlings directly affects the budding of plants. So, in the variant where the seedlings are 60 days old, the period of budding was observed for 56 days, which was observed 1 day earlier than the control variant. Seedlings of sweet pepper aged 50 and 70 days passed into the budding phase for 57 days. However, seedlings aged 40 days showed a tendency to delay the onset of plant budding. It has been established that the height of the plant before planting ranged from 14.7 cm to 18.6 cm. The highest rate of plant growth has been distinquished in the variant where the seedlings were 70 days old. When using the seedling age of 70 days, the test value was 2 controls more than the control index. The option using 60 day old sweet pepper seedlings was characterized by slightly low leaf numbers. The experiments established that when using seedlings with an age of 40 days, the plants were characterized by the smallest number of leaves on the plant. The age of seedlings and biometric indicators depend on the growing conditions, the timely passage of the photosynthesis process, the provision of nutrients, water. When using the seedling age of 60-70 days, the biometric indicators of seedlings, namely the height of the plants, the number of glosses, the mass of the plant significantly exceeds the biometric indicators of seedlings with an age of 50 or 40 days.

The article presents the results of the research dealing with the dependence of the mass, growth processes and the attachment height of the low bean of soybean under the application of different types of fungicides and biopreparation Rhizoactive in the Right Bank Forest-Steppe of Ukraine. Application of different types of fungicides had a positive influence on the plant mass of soybeans, growth processes and attachment height of a low bean. Indexes were defined in different years and at different development stages of a plant: budding, flowering and beans maturing. Throughout all development stages, the best indexes of soybeans height, their mass and attachment height of a low bean were under the complex application of preparations, in particular, the highest indexes were in the variants with the application of fungicides Impact K, 0,9l/ha; Koronet 300 SC, KC 0.8 l/ha at the background of seeds treatment with the inoculator Rhizoactove. Important selection features that are associated with the main morphological and biological characteristics of soybeans are the height, mass and lower bean attachment height of soybean. Productivity in general depends on the height and weight of plants, as the stem is an organ of conversion and transport of organic and mineral substances, which plays an important role in crop formation. Technology of soybean cultivation on irrigation provides suitability of varieties for mechanized harvesting, including resistance to pod shatter and lodging, optimal placement of the first beans on the plant and genotypes reaction to irrigation. For successful introduction into production, new soybean varieties must be not only high yielding but also suitable for mechanized harvesting, which is primarily due to the lower bean attachment height of the plant. Low first bean attachment leads to a decrease in the yield of the variety, since a significant number of beans are lost during combine harvesting. Yield losses because of the low attachment of the lower bean may reach 15-20%. This feature is associated with the total height of the plant. The height of soybean plants and the lower bean attachment largely depend on growing conditions. The research conducted by A.Ya Ala. and A.A. Hamolin have established that linear parameters of plants at irrigation considerably increase. In the south of Ukraine irrig

Purpose. To assess the relationship between distribution, microrelief structure and regenerative dynamics of meadow phytocenoses on slope lands and to establish the productive potential of renewable herbage with different methods of their grassing in the conditions of the right-bank Forest-Steppe. Methods. Field and laboratory research in grassland, hypothesis, dialectical, synthesis and analysis, induction, statistical. Results. A strategy was theoretically developed for restoring the forage grasslands on slopes, which provides for the selection of the most adapted species with high biological characteristics, their ecological and phytocenotic combination in highly productive mixtures, and development of ecologically safe technologies for the reconstruction of such lands on the basis of theoretical provisions on the demutational dynamics of herbal phytocenoses. The species of legumes and cereal grasses were selected for the research, which, according to their biological characteristics, are valuable fodder, medicinal, melliferous, soil-protective and phytomeliorative crops. It was found that in terms of phytocenotic properties, 40% of the species of the Poaceae family exhibit dominant properties, 40% are among the main cenose-formers, 20% are dominants in narrowly limited ecological conditions. It was revealed that the ecological structure of populations of natural phytocenoses of slopes most often consists of one dominant species and two subdominants, which are in certain proportions. Direction of the ecological strategy for the development of each species has been established and a ranked series has been constructed according to the indicators of the cenotic activity index. Renewable legume agrophytocenoses have the greatest potential for productivity with superficial or radical improvement, which in the seasons of use in 2019-20 provided the yield of green mass at the level of 27.03-47.33 t/ha and dry matter – 6.31-10.32 t/ha. Conclusions. When selecting the species composition of renewable perennial phytocenoses, it is necessary to use ecological-biological and phytocenotic approaches, according to which the species should be evaluated according to their adaptability to growing conditions, coenotic power, competitive ability, association and productivity. The best ecological resistance to growing conditions and the value of the production potential was shown by restorative grass stands based on leguminous grasses of the raised type of development.

Purpose. Determine the oil content and glucosinolate content and productivity of spring camelina and spring rapeseed as affected by varietal characteristics. Methods. The research was conducted in the educational-scientific-industrial complex of Uman National University of Horticulture. Spring rapeseed varieties ‘Belinda’, ‘Aidar’, ‘Heros’, ‘Jerry’ and spring camelina varieties ‘Zevs’, ‘Hirskyi’, ‘Slavutych’, ‘Mirazh’ were studied. Seeds were sown in a row to a depth of 1.5 cm with a seeder CH-16. The sowing rate was 300 seeds/m2, or 5.4 kg/ha. The crop was harvested separately by Sampo-500 combine. Results. In spring rapeseed, the highest yield was marked by variety ‘Aidar’ (2.52 t/ha) and the lowest by ‘Heros’ (2.43 t/ha). In spring camelina, the highest yield was in variety ‘Zevs’ (2.31 t/ha) and lower in ‘Hirska’ (2.15), ‘Mirazh’ (2.27), and ‘Slavutych’ (2.22 t/ha). The highest oil content among rapeseed varieties demonstrated ‘Aidar’ (43.7%). Slightly lower it was in ‘Belinda’ (43.2%), ‘Jerry’ (42.8) and ‘Heros’ (42.6%). Depending on the varietal characteristics, the highest percentage of oil content was found in spring camelina varieties ‘Zevs’ (45.1%). It was lower by 0.5 and 0.9% in ‘Mirazh’ and ‘Slavutych’. The lowest percentage of oil content (43.7%) was determined in camelina variety ‘Hirska. In spring rapeseed varieties, the highest content of glucosinolates was in ‘Aidar’ – 20.5 μmol/g, 0.3 and 0.5 μmol/g less in ‘Belinda’ and ‘Jerry’, and the lowest in ‘Heros’ (19.8 μmol/g). In spring camelina, the highest value was in the variety ‘Zevs’ (22.0 μmol/g), and the lowest in ‘Hirska’ (21.0 μmol/g). ‘Mirazh’ and ‘Slavutych’ contained 21.7 and 21.4 μmol/g of glucosinolatesm respectively. Conclusions. The productivity of oilseed crops varies under the same growing conditions: spring rapeseed, regardless of varietal characteristics, demonstrated higher yield compared to camelina. On average over the years of research and varieties, this indicator was 2.47 t in spring rapeseed, and 2.24 t/ha in spring camelina, which is 0.23 t/ha less. In rapeseed, the oil content of the seeds was 43.07%, the content of glucosinolates varied from 19.8 to 20.5 μmol/g. In spring camelina, the oil content of seeds was 1.33–44.40% higher, the content of glucosinolates ranged from 21.0 to 22.0 μmol/g. The level of profitability of the studied oilseed crops was high and varied as affected by varietal characteristics: in rapeseed from 122 to 141%, and in spring camelina from 182 to 196%.

Сорти льону олійного мають важливе значення для отримання його стабільного врожаю високої якості. Проте для льону олійного виявлена ​​значна варіабельність ознак насіннєвої продуктивності (кількість та маса насіння з рослини, маса 1000 насінин) і біохімічного складу насіння, однак відомості про реалізацію генотипового потенціалу культури обмежені. Саме через таку мінливість ознак льону олійного метою нашого дослідження було порівняння морфології рослин різних сортів під час вирощування саме в умовах Правобережного Лісостепу України. Проведені дослідження показали, що умови вирощування мають вплив на такі генотипові ознаки як висота рослин та кількість коробочок на рослині. Маса 1000 насінин та кількість насінин у коробочці є відносно стабільними показниками і мають незначну мінливість. Маса насіння з однієї рослини залежить від кількості коробочок на рослині, про що свідчить високий коефіцієнт кореляції. Найбільшу висоту рослин за всі роки досліджень мав сорт Лірина, найменшу – сорт Айсберг. Найвищу масу 1000 насінин мав сорт Південна ніч. Кращими за продуктивністю однієї рослини в умовах Правобережного Лісостепу України виявились сорти Еврика, Лірина та Блакитно-помаранчевий. Linseed varieties are of great importance for obtaining stable yields of high quality. However, for linseed, there is a significant variability in the signs of seed productivity (amount and mass of seeds from the plant, mass of 1000 seeds) and biochemical composition of the seeds, but information about genotypic potential realization of the culture is limited. It is because of this variability of linseed characteristics our study was aimed at comparing morphology of plants different varieties during cultivation precisely in conditions of the Right-bank Forest-Steppe of Ukraine. Studies have shown that growing conditions affect on such genotypic signs as height of the plants and number of fruitcases on the plant. Weight of 1000 seeds and number of seeds in the fruitcase is relatively stable and has insignificant variability. Weight of the seeds from one plant depends from number of fruitcases on the plant, as evidenced by the high correlation coefficient. The biggest height of the plants during the all years of research has variety Liryna, the shortest – variety Aisberg. The highest weight of 1000 seeds has variety Pivdenna nich. The best by productivity of the one plant in conditions of Right-bank Forest-Steppe of Ukraine were varieties Evryka, Lirina and Blakytno-pomaranchevyi.

Chickpeas are a valuable legume and drought-resistant crop. In conditions of climate change, it ensures the formation of a sufficiently high yield, which increases the interest of agricultural producers in growing crops. However, the presence of genetically determined plant protection (pubescence of plants and pod, which contain oxalic, malic and citric acids) from some pests makes it possible to grow environmentally friendly products, which consequently reduces the need to use plant protection chemicals. Field experiments were carried out on the experimental field of the Uman National University of Horticulture in the soil and climatic conditions of the Right Bank Forest-Steppe. To determine the selection value of collection varieties samples of domestic selection were grown. It should be noted that plants react significantly to extreme conditions (temperature and amount of precipitation) of cultivation precisely in the period from gathering to flowering. It is during this period of time that excess moisture leads to shedding of flowers and, as a result, to a decrease in yield. The meteorological conditions for growing crops, which are expressed in the duration of both the growing season as a whole and its individual phases, have a significant effect on the length of the growing season. And so, according to our data, it was revealed that the difference in the duration of the growing season of the studied selection samples in comparison with the standard was small and ranged from 3 to 5 days. The main indicator of adaptability to mechanized harvesting is the attachment height of the lower pod. It depends on the height of the plant itself and the shape of the bush that the culture forms. On the basis of average, it was revealed that the studied selection samples belong to tall plants, while the indicator of the attachment height of the lower pod, the Triumph standard had a high attachment of pod, two samples – moderate, which indicates the possibility of mechanized harvesting, while samples 230 and 210 – low. As a result of comparison of the obtained data on the yield of selection samples, their significant reaction to the growing conditions was revealed. Analysis of the average data helps to specify that the highest yield in the conditions of both 2019 and 2020 was provided by selection samples 180 (morphotype desi), while the lowest yield, but also within the standard, was found in sample 160 (morphotype gulabi)

Abstract The accurate measurement of hip motion is critical when one rates impairments of this joint, makes an initial diagnosis, assesses progression over time, and evaluates treatment outcome. The hip permits all motions typical of a ball-and-socket joint. The hip sacrifices some motion but gains stability and strength. Figures 52 to 54 in AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fourth Edition, illustrate techniques for measuring hip flexion, loss of extension, abduction, adduction, and external and internal rotation. Figure 53 in the AMA Guides, Fourth Edition, illustrates neutral, abducted, and adducted positions of the hip and proper alignment of the goniometer arms, and Figure 52 illustrates use of a goniometer to measure flexion of the right hip. In terms of impairment rating, hip extension (at least any beyond neutral) is irrelevant, and the AMA Guides contains no figures describing its measurement. Figure 54, Measuring Internal and External Hip Rotation, demonstrates proper positioning and measurement techniques for rotary movements of this joint. The difference between measured and actual hip rotation probably is minimal and is irrelevant for impairment rating. The normal internal rotation varies from 30° to 40°, and the external rotation ranges from 40° to 60°.
