“…At least 4–6 months period without frost is required for successful sweet potato cultivation. Sweet potato is a drought-tolerant crop; however, storage root yield increases with increasing soil moisture content [ 1 , 16 ] due to the deep root system. Therefore, the regions with well-distributed rainfall such as temperature zones between 30 and 40° latitudes in both hemispheres or the regions with irrigation infrastructure favor the cultivation of sweet potato [ 1 , 17 ].…”

Sweet potato (Ipomoea batatas L.) cultivation in Turkey is concentrated in one province situated in Mediterranean region only, which would not fulfill the domestic needs of the country soon. Therefore, cultivation of the crop in other provinces/climatic regions should be initiated to fulfill the domestic needs. The cultivation in other provinces requires thorough assessment of yield and quality traits of target crop. Therefore, yield and quality characteristics of four sweet potato genotypes (i.e., ‘Hatay Kırmızısı’, ‘Hatay Yerlisi’, ‘Havuc’ and ‘Kalem’) were assessed in the current study in Kazova and Niksar counties of Tokat province of the country having middle Black Sea climate in field experiments during 2018 and 2019. The cuttings of the genotypes were planted in Niksar during the second fortnight of April and first week of May in Kazova. The planting density was kept 90 × 45 cm. Data relating to number of storage roots, storage root weight, storage root yield per hill and storage root yield per hectare were recorded. Furthermore, quality traits, including dry matter ratio (%), protein ratio (%) and antioxidant ratio (%) of storage roots were also determined. The highest total storage root yield was recorded for ‘Havuc’ genotype during both years and locations, followed by ‘Hatay Yerlisi’ and ‘Hatay Kırmızısı’ genotypes. Overall, storage root yield (60.06 and 62.40 tons ha-1 during first and second year) recorded for the experiment at Niksar was higher than the storage root yield recorded for Kazova experiment (53.50 and 52.84 tons ha-1 during first and second year, respectively). The highest dry matter was produced by ‘Kalem’ and ‘Hatay Yerlisi’ genotypes during both years and at both locations, followed by ‘Hatay Kırmızısı’ and ‘Havuc’ genotypes. The storage roots of the tested genotypes accumulated higher dry matter at Kazova during both years. The highest protein content was obtained from the ‘Kalem’ genotype, and the protein contents of the ‘Hatay Yerlisi’ and ‘Hatay Kırmızısı’ genotypes were close to the ‘Kalem’ genotype. The results indicated that tested genotypes can successfully be cultivated in middle Black Sea climate. Therefore, production of sweet potato can be initiated in the future to meet the domestic needs for sweet potato in the country.

“…Sweet potatoes are food crops with wide ecological adaptability, drought-tolerant, often cultivated in the marginal soils under low agricultural input and are able to grow with limited water available for irrigation (Motsa et al, 2015a;Motsa et al, 2015b;Chipungu et al, 2018;Lestari et al, 2019). Sweet potato plantations can reduce soil erosion because of its vines' ability to cover the soil surface (Oshunsanya, 2016).…”

“…Other research of sweet potato on dry land showed that the crop produced as much as 5.35-17.47 ton ha -1 of storage roots and 11.76-22.88 ton ha -1 of vines. Whereas when planted on paddy fields, the production of storage roots could reach 19.90-64.52 ton ha -1 and vines ranging from 11.91-32.09 ton ha -1 (Lestari et al, 2019).…”

Sweet potato is a dual-purpose crop, which could produce both food and feed. The vine pruning prior to storage root harvesting was intended to increase the quantity and quality of fresh forage for animal feed. This study aims to evaluate whether periodic pruning can affect the storage root yield and its starch content. This experiment employed split-plot design with two factors and three replications. The first factor as main plot was vine pruning which consisted of four distinct pruning times (four times, three times, twice and once). The second factor as sub-plot was cultivars which consisted of six dual-purpose cultivars and two controls. The storage root yields, vine yields, starch yields and the reduction in storage root yields were observed. The results showed that the vine pruning decreased the storage root yields, with small increases the vine yields. The percentage of the reduction in storage root yields were 4-58%, while the decrease vine yields are relatively inconsistent. The starch yield of the cultivars with one pruning time were in the range of 2.34-6.67 ton ha<sup>-1</sup>. On the contrary, the three times pruning or more since 80 days after transplanted can reduce the starch yields for more than 50%. The slight increase in vines yield due to pruning was followed by the decrease in storage root yields and starch content of the sweet potato.

The soil microbial communities and growth of sweet potato are often affected by soil type. This study evaluated the variations in microbial communities of paddy and upland soils used for two sweet potato cultivars (Jinhongmi and Sinjami) cultivation by their fatty acid methyl ester (FAME). The pH, available P 2 O 5 , exchangeable K, Ca, and Mg of upland soil at the harvesting stage were significantly higher than those of paddy soil. The moisture content of paddy soil (28.5%) has increased by 6.7% as compared to upland soil (p < 0.001). The average microbial biomasses in paddy soil were approximately 2.8 times larger for arbuscular mycorrhizal fungi (AMF) and 1.4 -1.6 times larger for fungi, total bacteria, Gram-positive bacteria, total FAMEs, Gram-negative bacteria, and actinomycetes. In addition, The total FAMEs, Gram-positive bacteria, fungi, total bacteria, and AMF in Jinhongmi cultivated soils were significantly larger than those in Sinjami cultivated soils. AMF communities in paddy soil showed significantly larger than that in upland soil (p < 0.001) indicating AMF are potentially responsible for the microbial community differentiation between paddy and upland field. The tuber yield of sweet potato was 28% higher, respectively, in the paddy soil and Sinjami treatment than in the upland soil and Jinhongmi treatment. It was confirmed that the paddy field was more effective on the productivity of sweet potato and soil microbial biomass.
