“…A batata-doce pode ser utilizada na alimentação humana e animal, ou ainda como alternativa na produção de biocombustível (álcool), amido, macarrão, doces, sobremesas industrializadas e farinha, sendo considerada uma planta de usos múltiplos (OLIVEIRA, 2013;ERTHAL;ZAMBERLAN;SALAZAR, 2018;MAINO et al, 2019). Para muitas pessoas, a batata-doce é vista apenas como uma cultura de subsistência, devido a sua difusão na alimentação familiar, sendo comumente consumida assada ou cozida, contudo, também pode ser usada como matéria prima industrial, possuindo alto valor nutricional, devido a presença de carboidratos, β-caroteno e antocianinas (responsáveis pela variação de cor de algumas polpas), compostos fenólicos, fibra dietética, ácido ascórbico e fólico, provitamina A e sais minerais (VIZZOTTO et al, 2018).…”

A batata-doce é considerada uma das principais culturas tuberosas cultivadas em nível global, devido as suas características de adaptação e cultivo, além da variedade de usos, que vão desde a alimentação até a produção de biocombustíveis. Neste sentido, o presente trabalho teve como objetivo descrever de forma generalizada a cultura da batata-doce com ênfase na dinâmica do nitrogênio. Para alcançar tal objetivo empregou-se uma revisa bibliográfica fragmentada em seções. A primeira seção aborda a cultura como um todo, trazendo sua importância socioeconômica, origem, morfologia, condições para seu desenvolvimento e fenologia. Enquanto, a segunda seção foca-se na dinâmica nutricional da cultura, com ênfase no nitrogênio, abordando as necessidades nutricionais gerais, a dinâmica do nitrogênio e sua relação com o amido e alternativas para manejar o nitrogênio na cultura, como o emprego de bactérias fixadoras de nitrogênio e fontes orgânicas do elemento. Como considerações destaca-se a exigência da cultura pelo nitrogênio, entretanto, o estabelecimento de recomendações para o elemento, é dificultado pela alta variação de resposta da cultura, fator possivelmente relacionado ao processo de fixação biológica. Portanto, mais pesquisas sobre a fixação biológica e sua interação com a adubação convencional e orgânica são necessárias para gerar um manejo mais eficiente na cultura.

“…occupy the seventh in the world food culture, based on production volume. It is a root that is characterized by the following aspects: high rusticity and a broad spectrum of potential use, easy cultivation, wide adaptation to different types of climate and soil, tolerance to drought, and the ability to adapt to marginal conditions, in addition to a relatively low cost of production with high productivity and high return on investment (FAOSTAT, 2018; Vizzotto et al., 2018).…”

Beauregard sweet potatoes have high concentration of β‐carotene, a precursor of vitamin A, which helps in human growth and development. The objective of the work was to optimize the Beauregard sweet potato flour production process, maintaining a high content of carotenoids. A central rotational composite design 23 was performed with three central points and six axial points. Independent factors were ascorbic acid concentration, immersion time, and drying temperature while investigated responses were carotenoid, vitamin C and protein content and color. The optimum conditions for the processing of sweet potato flour was ascorbic acid concentration used in the immersion of 1.84 g 100 ml–1, immersion time of 43.6 min, and drying temperature of 43.3°C. The process showed 100% general desirability, and the product obtained present 419.85 μg g–1 of carotenoids, 24.92 mg 100 g–1 of vitamin C, and 5.26 mg 100 g–1 of protein content. Practical applications Sweet potato (Ipomoea potatoes L. (Lam.)) is an energetic food, containing a high content of vitamins and minerals. The Beauregard variety, with orange pulp, has advantages over other cultivars because it has high productivity and is more nutritious due to its high content of β‐carotene (115 μg g–1 of fresh roots), in addition to different color and flavor. The drying process of roots for the production of flour is a method most used to reduce post‐harvest losses that occur due to its high perishability. The use of experimental planning through a central rotational composite design (DCCR) is an efficient statistical tool that allows determining the ideal conditions of the Beauregard sweet potato flour production process in which the high nutritional value is maintained, preserving the B‐carotene) and with less alteration of the color sensory attribute.

“…Its rusticity guarantees resistance to drought, little demand on nutrients and advantageous competition with weeds, for quickly covering the soil. In addition, to use in human food, sweet potatoes can be used in animal feed and ethanol production (Corrêa et al, 2016;Silva, Almeida, Alvim-Ferraz, & Dias, 2018;Suparno, Prabawardani, & Pattikawa, 2016;Vizzotto, Pereira, Castro, Raphaelli, & Krolow, 2017).…”

Chicken manure is accessible to family farmers, is produced in large volumes, and has a low cost. Therefore, it can be an alternative to increase the productivity of sweet potatoes (Ipomoea batatas), which is a culture of socioeconomic importance. The objective of the study was to evaluate the productivity of sweet potatoes under different doses of chicken manure, with and without liming, comparing to the use of chemical fertilizer NPK, in very clayey soil, from the perspective of economic efficiency. The experiment was conducted in the field from September 2019 to March 2020 in Manaus, Amazonas, Brazil. The experimental design was in randomized blocks with four replications, in a split-plot scheme 2 × 5 + 1 (presence or absence of liming; five doses of chicken manure; and NPK, respectively. The evaluated parameters were: total and commercial productivity; number of total and commercial tuberous roots; harvest index; individual fresh mass, length, and diameter of tuberous roots. The effect of chicken manure was not influenced by the liming and there are no differences in agronomic values related to NPK. The dose of chicken manure that results in maximum production of the queen sweet potato variety is approximately 13 t ha-1, producing 25.2 t ha-1, while the resulting dose in maximum profit is approximately 12 t ha-1 with a production of the 25.1 t ha-1. The selling production directly to the final consumer increased profit by approximately 57.3%. Purchasing the input directly from the manufacturer reduced costs by approximately 74.5%. The use of chicken manure has a greater economic advantage compared to NPK in very clayey soil.
