“…The attributes of higher growth results from increased nitrogen could be attributed to the effects of nitrogen on cell division and elongation, synthesis of amino acids as well as its impact on some physiological processes favoring growth [11,16]. Tsuno & Fujise [17] reported that nitrogen increased dry matter and leaf area index of sweet potato and also increased the distribution ratio of above ground to underground parts, while Hay & Walker [14] indicated that an increase in nitrogen application rate increased leaf size and longevity as well as branching and leaf area index.…”

Sweet potato (Ipomoea batatas (L) Lam) that able to thrive in the tropical harsh condition is one of the vital commodities to small scale farmers. With more than 6,500 wild, traditional and improved varieties globally and the importance of nitrogen (N) fertilization in producing high yield of quality tuber in the tropical region, further research on selected sweet potato varieties and optimum N fertilization was conducted in Field 2 of University Putra Malaysia (UPM) that specifically determining tuber yield and its nutritive quality (carbohydrate, total sugar, and β-carotene) and its selected plant parameters. Five varieties (labeled as A, B, C, D, and E for accessions E10073, E10236, E10136, E10173, and E10051, respectively) at four N application rates (0, 17, 34, and 68 kg ha -1 ) were used in the 2-factorial experiment with a split plot design. With generally of no N*varieties interaction effect on all parameters, the N rate for optimum yield determined by regression method was 45 kg N ha -1. At this N rate, the resulted high yielder varieties were E and D with estimated yields of 15.1 and 14.5 t ha -1 respectively. The medium yielders were A (13.1 t ha -1) and C (12.7 t ha -1), while the low yielder was B (11.6 t ha -1 ). The LAI and photosynthetic rate for obtaining higher yield at the N rate were > 1.6 units and > 37 u moles m -2 s -1 respectively. Much higher leaves relative to stem did not cause the Peru originated variety (C) had higher yield than those of the high yielder Malaysian varieties. The high yielder E (E 10051) had carbohydrate, total sugar and β-carotene of 22.4%, 8.3%, 9248 ug g

“…The content of beta-carotene in sweet potatoes is also influenced by other factors such as the cultivar type, air and soil temperature, day length, radiation, soil type, and incidence of pests and diseases, as well as agronomic practices [ 21 , 22 , 23 ]. In contrast, the dry matter content of sweet potatoes is affected by various factors, including soil quality, temperature, moisture, and mineral availability, particularly potassium, phosphorus, and nitrogen [ 24 , 25 ]. Moderately high temperatures between 20 and 30 °C promote a high dry matter content in sweet potatoes, which, however, begins to decline at temperatures >30 °C [ 26 ].…”

This study evaluated the genotype by environment interactions in the yield and nutraceutical traits of the orange-fleshed sweet potato (OFSP) storage root in different agro-climatic zones of northern Ethiopia. Five OFSP genotypes were cultivated at three different locations following a randomized complete block design, and the yield, dry matter, beta-carotene, flavonoids, polyphenols, soluble sugars, starch, soluble proteins, and free radical scavenging activity were measured in the storage root. The results showed consistent variations in the nutritional traits of the OFSP storage root depending on both the genotype and the location, as well as on their interaction. Ininda, Gloria, and Amelia were the genotypes that provided the higher yield and dry matter, as well as the higher content of starch and beta-carotene; they also showed a high antioxidant power. These findings suggest that the studied genotypes have the potential to alleviate vitamin A deficiency. This study demonstrated a high possibility of sweet potato production for storage root yield in arid agro-climate regions with limited production inputs. Moreover, the results suggest that it is possible to enhance the yield, dry matter content, beta-carotene, starch, and polyphenols of the OFSP storage root through genotype selection.
