“…The introduction of crops with short cycles, such as sweet potato (Ipomoea batatas (L.) Lam), in intercropping is an income option, as it demands low production costs and has a relatively short cycle of 90 to 150 days until harvest (Silva;Lopes;Magalhães, 2008, Aguirre et al, 2020, Coelho et al, 2022. Sweet potato cultivation stands out for its profitability due to its simplicity of cultivation and low operational cost of development (Oloniyo et al, 2021).…”

Agroforestry systems (AFS) play a key role in recovering degraded areas and restoring fragmented landscapes, enabling the diversification of species that can be cultivated simultaneously. In this context, the introduction of short-cycle crops, such as sweet potato (Ipomoea batatas (L.) Lam), in agroforestry systems is a viable and affordable option for income generation due to low production costs and the relatively short cycle of this crop. A species of the Convolvulaceae family, sweet potatoes are recommended for hot climates. In this scenario, the present study aims to evaluate the production of sweet potatoes in different agroforestry arrangements. The experiment was conducted at the Experimental Farm of the Federal University of Western Pará in Santarém, State of Pará, Brazil. Sweet potato was cultivated in agroforestry systems in a completely randomized design, with three plots in each treatment (full sun, African mahogany reforestation, and teak reforestation). The results showed that, in the specific conditions of this study, sweet potato did not adapt to cultivation in shaded areas. The highest production was in full sun, where the consortium with forest species still does not provide shading for cultivation. These findings highlight the importance of considering the specific characteristics of sweet potato and its sunlight needs when planning and implementing agroforestry systems. Understanding these results contributes to making informed decisions regarding the development of cultivation and management strategies aiming to optimize sweet potato production in agroforestry systems.

“…According to data of the 2006 and 2017 Agricultural Census, the number of rural properties that use synthetic or organic compounds in the region in which the present work was carried out (Serra de Ibiapaba, CE, Brazil) increased from 7,505 to 8,703. Regarding the application of soil fertilizers to sweet potato crops using organic or mineral sources, researches have confirmed that the availability of nutrients is indispensable for high yield indexes (AGUIRRE et al, 2020;HIRATA, 2014). Sweet potato, as other vegetables, has a relatively high demand for primary macronutrients.…”

Effect of NPK fertilizer rates and growth regulator concentrations on sweet potato crop yield

et al. 2023

The low mean yield of sweet potato crops in Brazil is related to several inadequate crop management practices. Considering the increasing production of this vegetable, the objective of this work was to evaluate the yield response of sweet potato crops subjected to different NPK fertilizer rates (NPK) combined with different growth regulator concentrations. The experiment was carried out in a randomized block design, with a 5×5 factorial arrangement consisted of 5 NPK fertilizer rates (0, 696, 1044, 1392, and 1740 kg ha-1) combined with 5 growth regulator concentrations (0, 20, 25, 30, and 35 mL L-1). Numbers of total and commercial roots per plant were affected by the factors tested, presenting a linear increase as the rates and concentrations were increased. The highest estimated sweet potato yield was 43 Mg ha -1, which was obtained using a NPK rate of 1522.64 kg ha-1 and a growth regulator concentration of 34.69 mL L-1. The higher NPK rates improved water use efficiency up to a maximum value of 8.1 kg m-3 with application of the NPK rate of 1740 kg ha-1. After determining a fixed yield level, the production factors tested act as imperfect substitutes in some intervals of variation of the inputs.

“…It has potential for use in tuberous roots and shoots, in human and animal food. Tuberous roots are an important source of low glycemic index carbohydrates, vitamins and minerals for the human diet, especially magnesium, potassium, phosphorus, and calcium (Aguirre et al, 2020;Nunes et al, 2020).…”

“…In a study by Aguirre et al (2020), it was found that the tuberous roots of cream-colored sweet potato had higher levels of calcium than the tuberous roots of other colors. In this same context, the purple-colored tuberous roots are rich in anthocyanins (Adebamowo et al, 2015), and with orange-colored flesh, they are rich in beta-carotene (Vizzoto et al, 2017).…”

Sweet potato [Ipomoea batatas (L.) Lam.] is a nutritious food, from an easy-to-handle cultivation, present in all Brazilian regions, with great socioeconomic relevance. There is a wide genetic diversity of sweet potato, expressing different flesh and skin colors, and containing different nutritional values. However, only sweet potatoes with cream flesh and white or purple skin are present in the Manaus market. It is important to promote the visibility of the varieties that are being cultivated in a less expressive way, often only by the indigenous people. In this way, the valorization of the product and the conservation of agrobiodiversity will be encouraged. One obstacle to identifying varieties is that the same variety can have different names, and the same name can be given to different varieties. Therefore, it is essential that a morphological description of the varieties present locally is made. This will be a subsidy for future research and actions aimed at the development of the primary sector that has the sweet potato as its object. Given the above, this work aimed to morphologically describe the sweet potato varieties Cenoura, Margarita, Rainha and Roxa present at the Experimental Farm of the Federal University of Amazonas. The Cenoura, Rainha and Roxa varieties have different skin and/or flesh colors and a tuberous root shape, catering to different consumer tastes. The Cenoura variety (skin and orange flesh) has the potential to be cultivated by Amazonian farmers and introduced in the local market (Alves, 2021; Filgueira, 2008; Huamán, 1991).
