“…Recently, there has been a debate in scientific publications about the usefulness or harmfulness of V. album for tree and shrub plantations (Ivchenko et al, 2014;Bondar et al, 2020). A number of authors (Ivchenko et al, 2014;Melo et al, 2023) hold an opi nion that V. album, thanks to its evergreen leaves, can be used as a decorative element of the landscape for park zones or for woody plants on sides of roads, since the harmfulness of this hemiparasitic plant is insignificant.…”

Background. European mistletoe (Viscum album L.) is a hemiparasitic, autotrophic plant, which is an integral part of natural and urbanized ecosystems of Ukraine, in particular Zhytomyr Polissia. V. album is considered to be an aboriginal species which is largely responsible for the deterioration of the sanitary condition of woody plants. In particular, it causes their premature drying, a sharp decrease in the intensity of growth and yield of fruit. This study pursues the following goals: 1) to identify the species of trees affected by V. album and which ones it prefers in the conditions of Zhytomyr Polissia; 2) to study the biology of the development of V. album in the conditions of the region; 3) analysis of the degree of damage to trees by V. album using the coefficient of complex assessment. Materials and Methods. The reconnaissance method was used to determine the distribution of V. album, the type of damage and the intensity of damage to tree plantations and the degree of tree damage by mistletoe was determined using the coefficient of comprehensive damage assessment (Ccda). Results and Discussion. It was found that out of the total number of affected trees, B. pendula (27.13 %), R. pseudoacacia (17.04 %) and P. tremula (11.13 %) were the most commonly infested by V. album in the region. At the same time, 46 % of the trees are slightly damaged, 31 % are moderately damaged and 23 % are insignificantly damaged. It was found that without human intervention, the number of populations and the number of V. album tend to increase. Conclusions. On the territory of Zhytomyr Polissia, V. album has entered the category of invasive plants. V. album was detected on 20 tree species, of which the number of trees affected by V. album reached 41.54 % of the total number of the examined trees. The vast majority of V. album populations (61 %) are growing. The largest numbers of V. album shrubs were recorded on trees aged 60–80 and 80–100 years, accounting for 23 % and 25.13 % of the total number of trees infested by V. album, respectively.

“…З використанням ОСВ для поліпшення властивостей чорноземів вирішуються одночасно проблеми збереження родючості ґрунтів, збіль шення виробництва сільськогосподарської продукції й утилізації ОСВ [11,12]. Виходячи зі складу та вмісту поживних і органічних речовин, найбільш поширеним у світі є використання ОСВ в якості органічних добрив [13]. Внесення ОСВ в ґрунт забезпечує його головними еле ментами живлення -азотом, фосфором, калієм [13], а також активізує ґрунтову мікрофлору.…”

Goal. To assess the effect of various organic fertilizers on the yield of hazelnut plantations in the conditions of the Southern Steppe of Ukraine. Methods. Field experiment, laboratory-analytical, comparative. Results. The influence of organic fertilizers of various origins was studied (cattle manure; chicken droppings; Biofertilizer No. 1 — sewage sludge (SW) of the biological treatment station (SBO) «Pivdenna» in Odesa + winter wheat straw + Microbacterium barkeri LP-1 (M. b.); Biofertilizer No. 2 — «Southern» SBO + sunflower seed husks + M. b.; «Pivdenna» SBO, Odesa) on the agrochemical parameters of ordinary medium-humus chernozem in the conditions of the Southern Steppe of Ukraine for the cultivation of hazelnuts. It is shown that in comparison with the control of 2021 and 2022, an increase in the content of easily hydrolyzed nitrogen, mobile forms of phosphorus and potassium, and organic matter is noted in all variants of the experiment. Conclusions. The use of organic fertilizers of various origins for the cultivation of hazelnuts in the conditions of the Southern Steppe of Ukraine helps to increase the content of the main agrochemical indicators of the soil — easily hydrolyzed nitrogen (91.0—98.0 mg/kg with 84.0 mg/kg — control), mobile phosphorus compounds (174.75—306.30 mg/kg at 138.75 mg/kg — control), potassium (112.00—166.90 mg/kg at 108.40 mg/kg — control) and organic matter (3.78—4.18% and 3.76% — control). The advantages of biofertilizers No. 1 and No. 2 based on sewage sludge with the use of vegetable fillers (winter wheat straw and sunflower seed husks) and the phosphate-mobilizing bacterium Microbacterium barkeri LP-1 are shown. Organic fertilizers contribute to the increase in the content of nutrients in the soil, the activation of the activity of eco-trophic groups of microorganisms, which leads to an increase in the biological activity of the soil and, accordingly, the yield of agricultural crops.
