“…Nevertheless, the population's need for vitamins is more relevant exactly in the cold season, when the likelihood of getting sick with respiratory viral diseases increases and immunity needs support. Onion cultures are of particular interest in this regard, because they uniquely combine a rich vitamin composition, antibacterial properties of essential oils, and the presence of biologically active compounds in the composition [1,2].…”

“…To obtain green leaves, perennial onion species are more suitable, because when growing in the open ground from one plot of perennial onion, you can reap the harvest 2-3 times per season [3]. The use of onions for these purposes is also justified, but this type of onion is more focused on the formation of a juicy bulb, it is also more susceptible to various diseases and pest damage [4].…”

“…Bulb onions, the most used species in our country for winter production of green leaves. Nevertheless, in this case there are some difficulties, for example, a long period of rest of the bulbs [4]. Of course, there are a number of measures to speed up germination, but this requires additional time and money, and when using various chemicals, the question of environmental friendliness of the products obtained arises.…”

In 2022-2023, experiments were conducted to study the effect of additional lighting on the growth, development, and vitamin C content of perennial onions during their forcing in protected ground in winter. Getting green vegetables in the cold season is of particular relevance in the Middle Urals, since the population during this period is particularly susceptible to immunity decrease, due to a lack of solar energy, a deficiency of vitamins and biologically active substances, therefore forced to use synthetic vitamins to strengthen its immunity. Although it is known that the vitamins contained in food bring the greatest benefit. Adding green onions to food is one of the simplest and most inexpensive ways to enrich the diet of the population. The use of perennial species of onions, which have a different appearance and taste different from each other, is also a way to diversify it. The purpose of the research: to study the effect of additional lighting on the yield of perennial onions and the vitamin C content during their forcing in winter using the method of immersion hydroponics. During the experiments, such indicators as changes in leaf length and the number of leaves on the plant, as well as individual plant productivity and yield were recorded. In addition to phenological observations, research was conducted on such indicators as the concentration of cell fluid, electrical conductivity, PH of perennial onion leaves. As a result, it was found that Allium nutans, which was grown without supplementary lighting, has the highest yield – about 2.5 kg/m2. For all the studied types of onions in 2023, results were obtained for higher electrical conductivity in onions grown with additional lighting. The difference was 27-61%. All the results obtained were processed using mathematical statistics methods. The results of experiments on the effect of additional lighting did not give unambiguous results, further more detailed study is required.

Abstract. In experiments conducted in 2021–2022. on the basis of the educational and experimental farm of the Ural State Agrarian University, studies were carried out on the influence of the feeding area and planting dates on the productivity and biochemical composition of perennial onions. The territory of the Middle Urals is located in a difficult climatic zone, with severe winters and warm summers. The weather in this area can change very quickly, and therefore, for cultivation in the Middle Urals, plants should be selected that will easily endure the vagaries of the weather, including green crops. These characteristics correspond to perennial onions, which are able to produce high yields of green leaves even in risky farming. Good resistance to pathogens, less susceptibility to pests compared to onions, as well as a wide variety of species that differ in external characteristics and taste make perennial onions excellent plants for obtaining valuable vitamin greens. The purpose of the study: to study the biological characteristics of perennial onions, as well as to find out the effect of the feeding area on their yield and biochemical composition. Methods. In the experiments, the following factors affecting the yield of perennial onions were investigated: leaf length, number of leaves per plant, the appearance of flower stalks, individual plant productivity. Results. In the course of the study, it was found that the highest yield is observed in all types of onions when grown with a distance in a row of 5 cm, the highest individual productivity was shown by batun onion plants when grown in a row with a distance between plants of 15 cm and slime onion with a distance between plants in a row of 25. In addition, there was a deterioration in the biochemical composition of the leaves of all the studied types of onions when planting in 2022 compared to 2021 and an increase in the concentration, electrical conductivity and acidity of cell sap in 2022 compared to 2021. Scientific novelty. Ledebur onion is the least studied of the onion species presented in the study, but it has good commercial and nutritional properties. Previously, this type of onion was not studied in the Middle Urals as a vegetable plant.
