Sweet potato (Ipomoea batatas L.) is a new crop for soil and climatic conditions of Ukraine, the active implementation of which is hindered by the lack of recommendations on technological aspects of cultivation. One of the important technological measures for growing sweet potatoes is the use of soil mulching, which improves the water regime and regulates the thermal regime of the soil; prevention of weed growth and growth of sweet potato shoots to the soil. Thus, the aim of the research is to determine the efficiency of growing sweet potatoes in the Forest-Steppe of Ukraine by different methods of soil mulching. Field research was carried out on typical low-humus light loamy chernozem on loess loam. It was noted, that when growing sweet potatoes on ridges, the introduction of mulching the soil with black polyethylene film provides more active growth of the vegetative mass throughout the growing season (5.33 shoots/plant with a total length of 252.1 cm), while growing without ridges has a positive effect on plants growth due to the general absence of mulch (2.53 shoots/plant with a total length of 107.8 cm). The use of ridges and mulching the soil with black polyethylene film causes the yield of sweet potato tubers at 34.8 t/ha, while the mulching of the soil with straw, the yield was 18.3–21.9 t/ha, without mulching – 13.0–17, 1 t/ha. Mulching with black polyethylene film ensures the accumulation of vitamin C and starch in sweet potato tubers. When growing the culture on ridges by this method of mulching, the maximum level of vitamin C according to the experiment (4.78 mg/100 g) and starch (11.73 %) was noted. The introduction of mulching and ridge formation involves additional material and labor costs, but helps to reduce weed control and tuber digging costs. When growing sweet potatoes on ridges with mulching with black polyethylene film, the minimum additional labor costs for the formation of a unit of yield (1.95 man-minutes/kg of tubers) were noted, while without mulching and without ridges this figure was 6.76 man-minute/kg

“…Sweet potato medicinal properties are well documented, highlighting their anti-inflammatory, antitumorous, antidiabetic, antioxidant and antimutagenic activity; these have been related to their high polyphenol concentrations (Hue et al, 2011;Mohanraj & Sivasankar, 2014;Naz et al, 2017;Katayama et al, 2017;Dinu et al, 2018;Sun et al, 2019;Islam, 2019), which in turn coincides with those evidenced in other members of Convolvulaceae. Plants can be used as taxonomic markers in search for new bioactive substances (Omotayo & Borokini, 2012); in this sense, some species related to sweet potato, such as Merremia emarginata (Burm.…”

“…Sweet potato is a typical plant of tropical regions, where it is cultivated due to its high content of carbohydrates and nutrients; mainly its roots are consumed; although, leaves are also used as a vegetable in Asian countries (Dinu et al, 2018). In this sense, edible organs of the plant have been studied in relation to their bioactive compounds content (mainly phenolic-type antioxidants).…”

“…however, it has been established that varieties with purple-fleshed roots have regularly higher polyphenol content than varieties with roots flesh of other colors (such as yellow and white) (Chao et al, 2014;Tang et al, 2015;Zhang et al, 2018;Šlosár et al, 2020). When comparing polyphenols concentration, as well as antioxidant and antiproliferative activites of sweet potato extracts, it is evident that aforementioned variables not only depend on genotype of the plant, but are highly influenced by used organ (even between parts of the same organ, such as roots peel and roots flesh, or leaf blade and petiole), collection time, solvent, extraction conditions, and quantification method (Islam et al, 2002;Naz et al, 2017;Dinu et al, 2018;Kobayashi et al, 2019;Sun et al, 2019).…”

Ipomoea batatas has an enormous projection as functional food and it is an excellent source of anticancerous or chemopreventive substances. Plant tissue culture offers the possibility of inducing secondary metabolites production under controlled conditions and their projection for industrial purposes. To establish the state of knowledge regarding advances in polyphenols chemical elicitation from I. batatas and the possibility of producing potential anticancerous compounds in vitro culture systems, a bibliometric review and an analysis of information available until 2020 were made. Results showed that research field on which review was carried out is current and has a growing trend; however, sweet potato cell suspensions evaluation is scarce. Elicitation using compounds with hormonal effects represents a good alternative to increase phenolic acids production in this species. Advances in phenols elicitation from sweet potato cell suspensions will require search superior genotypes, and associating this knowledge with in vivo and in silico studies.

This study evaluated the elements of production, the content of bioactive compounds, and the antioxidant activity of some types of garlic: softneck—Allium sativum L. var. sativum, Rocambole—A. sativum var. ophioscorodon (Link) Döll, and chives—A. schoenoprasum L. The mean yields and the distribution of bioactive compounds in the bulb, in the cloves of the bulb, as well as in the bulbils formed in the inflorescence, were determined. The average production/ha in the case of chives highlighted a yield of 27.83 t ha−1 of mature bulbs. All these were determined to obtain a better understanding of the biological functionality of the different morphological parts of this species. The content of vitamin C and flavonoids was significantly higher (p ≤ 0.05) in Rocambole than in the other varieties. The phenolic compounds were higher in the case of chives, followed by Rocambole and then by softneck garlic. The content of bioactive compounds was higher in the younger organ, depending on the morphological organ (bulbs, cloves, and bulbils on flower stalks) within the same variety. The vitamin C content was higher in the cloves (15.68 mg 100 g−1), followed by the bulbils in inflorescence (14.64 mg 100 g−1), and the mature bulb (13.14 mg 100 g−1) in Rocambole. The bioactive profile of garlic depends on the age of the morphological organ, and the bioactive concentration decreases with its maturity. Therefore, unripe garlic has the best potential to be used for its health benefits. The versatile health effects and nutraceutical properties of garlic can be attributed to the variety of bioactive compounds, mainly polyphenolic substances with strong antioxidant properties, as well as the morphological organ (mature bulb with cloves, a one year bulb derived from bulbil, or bulbil in bloom).
