Sweet Potato Flour

Sweet potato (Ipomoea batatas) is a food crop that supplies energy, minerals and vitamins C and B. Some cultivars are very rich in carotenoids (pro-vitamin A). In this study were evaluated and compared the total carotenoids content of two cultivars and the losses on the dehydrated extruded sweet potato flour. Samples from organic and conventional crops were analyzed, in the form of fresh and dehydrated extruded samples. Total carotenoids content of the fresh product, expressed on wet basis, was of 437 µg 100 g-1 for the cream cultivar and 10,12 µg 100 g-1 for the orange cultivar. After dehydration, losses of total carotenoids were of 41% and 38%, respectively. The fresh orange cultivar presented high total carotenoids content in comparison to the cream cultivar. The extruded orange sweet potato flour showed the lowest losses in total carotenoids. Therefore, the processed flour of orange sweet potato could be used to obtain pre-gelatinized extruded flour with high total carotenoids content.

Solution Ph

Sweet potato [Ipomoea batatas (L.) Lam.] is cultivated on soils varying widely in chemical properties, but relatively little is known about the effects of pH on the growth of this crop. In commercial and subsistence agriculture, sweet potato is propagated mostly from stem cuttings. This paper reports effects of a range of pH treatments (3.5–8.0) in flowing solution culture on early growth from cuttings of 15 sweet potato cultivars. Root growth was either greatly reduced or inhibited at pH 3.5. Increasing the pH to 4.0 markedly increased root development. Further increases in solution pH from 4.0 to 8.0 did not appear to affect root growth in most cultivars. Top growth in most cultivars showed a tendency to increase when pH was increased from 3.5 to 5.5 before declining with further increases in solution pH. The sweet potato cultivars studied differed widely in their tolerance to low pH, producing 16–48% of maximum top dry mass at pH 3.5. Tissue analysis from selected cultivars showed that K and Ca appeared to be limiting at pH 3.5, while P may have been deficient at pH 8.0. Results of this study indicate that low pH per se does not appear to be a major factor responsible for poor sweet potato yields in acid soils.

The sweet potato [Ipomoea batatas(L.) Lam.] cultivars ‘Jewel’, ‘Centennial’, ‘Caromex’, and breeding lines ‘W-70’, ‘W-152’, and ‘Tinian’ (PI 153655) were evaluated for metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as–triazin5(4H)-one] tolerance in greenhouse and field studies. Tinian was the most tolerant line. Its yields were not reduced by 2.2 kg/ha metribuzin in the field. Jewel, Centennial and W-152 were intermediate in response to metribuzin, and W-70 and Caromex were most susceptible. Regression analyses indicated a high correlation between the response of sweet potato cultivars to 0.5 ppm metribuzin incorporated in a potting mix in the greenhouse and their response to 1.1 kg/ha metribuzin applied after transplanting in the field.

Abstract. Samiyarsih S, Fitrianto N, Azizah E, Herawati W, Rochmatino. 2020. Anatomical profile and genetic variability of sweet potato (Ipomoea batatas) cultivars in Banyumas, Central Java, based on RAPD markers. Biodiversitas 21: 1755-1766. Indonesia has developed a food consumption diversification based on local sources. Sweet potato (Ipomoea batatas) is one of the tubers of carbohydrate sources in addition to wheat, rice, corn, potatoes, and cassava. It has a wide distribution, and high cultivars diversity produces a high variation on its morphology, anatomy, and genetic modification. The objectives of this research were to investigate the anatomical profile and genetic variability of eight sweet potatoes (Ipomoea batatas) cultivars found in Banyumas, Central Java, Indonesia. Anatomical profile was observed by the embedding method and subjected to analysis of variance. DNA amplification using Random Amplified Polymorphic DNA (RAPD) method with 10 primers, namely OPA-1, OPA-2, OPA-3, OPA-4, OPA-9, OPA-11, OPA-13, OPA-15, OPA-16, and OPA-18. The result of the anatomical study showed that eight sweet potato cultivars have significantly different (p<0.05) variation in leaf anatomical profile. RAPD primers produced 52 amplified fragments varying from 100 to 1300 bp in size, and 90.40% of the amplification bands were polymorphic. The genetic similarity level is ranged from 0.37 to 0.93. Two unspecific groups were forming at a coefficient of 55% from the dendrogram. The first group consisted of one cultivar, Cangkuang, and the second group consisted of seven cultivars Antin, Ungu Tua, Borobudur, Sukuh, Sari, Beta, and Kidal. The nearest relationships cultivars were Borobudur, and Ungu Tua had the highest similarity coefficient of 93%, and the lowest similarity found in Cangkuang and Antin with a coefficient of 37%. The range of genetic distance of eight cultivars was from 0.37-0.93. Implementation of the research would particularly useful for the identification and evaluation of the genetic improvement of sweet potato cultivars.

The sweet potato (Ipomoea batatas L.) is relatively known vegetable species, but it is grown only on small area in the Middle European region. Its cultivars are characterized by different colour of tuber flesh which can be white, beige, yellow, orange and purple. The aim of this study was to determine and compare selected qualitative parameters of tubers (total carotenoids, vitamin C and total soluble solids) among orange, white and purple sweet potato cultivars. The field experiments were established at Slovak University of Agriculture in Nitra in 2016 and 2017. Sweet potatoes were grown by hillock system with using of black non-woven textile for soil mulching. The tuber harvest was realised on the 6th October 2016 and 13rd September 2017. The highest content of total carotenoids was found in orange sweet potato cultivars (78.47 - 122.89 mg.kg-1 fresh weight) and its values were multiple-fold higher in comparison with purple (4.22 mg.kg-1 f. w.) and white (10.71 mg.kg-1 f. w.) cultivars. Orange cultivars were also richer source of vitamin C (246.31 - 325.99 mg.kg-1 f. w.) compared to white (179.66 mg.kg-1 f. w.) and purple (187.75 mg.kg-1 f. w.) cultivars of sweet potatoes. The total soluble solids, expressing mainly sugar content, was higher in purple (10.13 °BRIX) cultivar of sweet potatoes, followed by cultivars with orange (8.52 - 9.72 °BRIX) and white (5.57 °BRIX) tuber flesh. Obtained results showed the significant effect of cultivar, characterized by different tuber flesh colour, on the composition and contribution of sweet potatoes for human health.

O objetivo foi avaliar o crescimento das plantas, produção de raízes de batata-doce (Ipomoea batatas) e grãos de milho pipoca (Zea mays) em sistema de cultivo solteiro e consorciado. Foram avaliadas quatro cultivares de batata-doce e uma de pipoca em blocos casualizados com três repetições em condições de campo. No cultivo solteiro, a pipoca e batata-doce foram espaçadas 75 cm entre linhas. No consorciado, o plantio da batata-doce foi no centro das entre linhas da pipoca. A adubação foi realizada com cama de frango. Aos 30, 60 e 90 dias foi avaliado o número de folhas, altura das plantas, diâmetro do colmo/baraços e comprimento de baraços. No florescimento foi determinada a matéria seca das plantas, na maturação fisiológica a produção de grãos da pipoca e aos 180, as raízes da batata-doce. Observou-se que a pipoca apresentou a maior produção de matéria seca, número de folhas, diâmetro de colmos e altura de plantas quando solteiro, as cultivares de batata-doce quando consorciadas menor produção de matéria seca e raízes, a produção de grãos de pipoca não apresentou diferença entres os sistemas de produção. O sistema consorciado de pipoca e batata-doce promove maior produção de matéria seca e produção de alimentos por área.

Four sweet potato cultivars and one popcorn in randomized blocks were evaluated with three replications in field conditions. In single cultivation, popcorn and sweet potatoes were spaced 75 cm between rows. In the intercropped, the sweet potato was in the center of between the lines of popcorn. Fertilization was carried out with chicken manure. At 30, 60 and 90 days, the number of leaves, plant height, stem/tiller diameter and tether length were evaluated. At flowering, the dry matter of the plants was determined, at physiological maturity the grain yield of the popcorn and at 180, the roots of the sweet potato. It was observed that the popcorn showed the highest production of dry matter, number of leaves, stem diameter and plant height when single, sweet potato cultivars when intercropped, lower production of dry matter and roots, the productivity of popcorn grains there was no difference between the production systems. The intercroped system of popcorn and sweet potatoes promotes greater production of dry matter and food productivity per area.
