Against the background of global climate change, most of the territory of Ukraine today is semi-arid, which causes a decrease in the efficiency of the vegetable growing industry. Due to aridity and elevated temperatures in summer, the normal growth and development of plants, namely vining cucumber, is disrupted. The efficiency of artificial irrigation is also decreasing due to the rise in the price of fresh water and energy carriers for its supply to plants. Soil absorbents and the use of mulching can solve these issues. The purpose of this study was to investigate the effect of various forms of soil absorbent against the background of the use of various mulching materials of organic and synthetic origin on the productivity of vining cucumber. This study involved field, laboratory, statistical, and computational-analytical methods. Studies have established that upon mulching the soil with black polyethylene film together with the introduction of a soil absorbent in the form of a gel, phenological phases of growth and development occur most quickly in vining cucumber plants, and the fruiting period increases by 11 days compared to the control. The combination of film mulching and absorbent gel allowed increasing the height of the main stem by 15.2%, the number of leaves on the plant by 43.9%, and the leaf area by 26.5% compared to the control version. It was established that the highest commercial yield is provided by mulching the soil with a black film together with the introduction of an absorbent in the form of pellets and gel – 56.6-56.8 t/ha, which is 27.5-27.9% more than the control. The marketability of the yield was 99.2-99.4%. Cucumber fruits for mulching with a film and applying an absorbent in the form of a gel had a high content of dry matter (5.3%) and the sum of sugars (2.20%). Lowest nitrate level (N-NO3) in cucumber fruits provided mulching with black agrofibre without an absorbent (53.0 mg/kg)
We studied the influence of humus and different norms of vermicompost on the yield, nutritional value, and antibacterial properties of common garlic (Allium sativum L.). The use of the vermicompost caused an increase in the garlic yield by 1.7-3.9 t ha-1 for cultivar "Prometei" compared to the control "Sofiiskyi" and by 2.2-5.2 t ha-1 in relation to the control of cultivar "Prometei". It was established that the calory content could increase up to 22.68 g 100 g1 of fresh weight with vermicompost manure 5 t ha-1, and the total content of sugar is increasing by 21.52-40.81% depending on the cultivar. The content of vitamins increased alongside with rate of vermicompost introduction. We also revealed the influence of variety factor on the accumulation of vitamins. The antibacterial effect of the garlic essential oils against Staphylococcus aureus, Escherichia coli and Bacillus subtilis was significant; the diameters of the inhibition zone were for S. aureus 21.35-27.10 mm, for E. coli - 16.97-26.46 mm, and for B. subtilis - 16.42-25.36 mm. The number of Mycobacterium smegmatis colonies decreased by 23.96-43.44%. This study has been proved that garlic juice had considerable antibacterial effect on the studied bacteria (S. aureus, E. coli and B. subtilis); therefore, it can replace chemical antibiotics that have undesirable effects on the body, like allergy and antimicrobial resistance. Our data shows that using of vermicompost was more effective than humus.

A food value of carrot roots is determined by a content of such chemical composition components as dry substance, ascorbic acid, carotene and other. The carrot value is also determined by its ability to be stored for a long time. The research aim was to study a food value change of different carrot sorts at storage open in boxes. The research gives an ability to search a carrot sort, suitable for long storage, and also to search arrangements for better preservation of carrot nutritiousness at storage. It has been established, that the dynamics and intensity of losses of the roots’ food value depends on sort peculiarities. Thus, during 7.5 months of storage sorts Daryna, Shantane KL and Nant Kharkiv lost from 0.92 to 4.12 % of dry substance. The content of total sugar decreased by 0.16 and 0.77 % of its initial content in sorts Daryna and Nant Kharkiv, whereas Shantane demonstrated the content increase at the end of storage by 0.29 %. The same tendency was observed also by changes of the content of monosaccharides and saccharose. The content of ascorbic acid and carotene during storage varied from increase to decrease. At the end of storage losses of ascorbic acid and carotene were 1.43–1.93 and 3.42–4.26 mg/100 g respectively. The content of nitrates at the end of storage in Daryna roots remained at the initial level – 202 mg/kg of the humid mass, in Shantane and Nant Kharkiv it decreased by 18 and 26 % respectively. At that it must be noted, that the processes of nutritiousness changes were more intensive in Daryna and Nant Kharkiv roots. In Shantane the carrot roots content changes of chemical composition components were slower.
