DETERMINANTS OF VALUE ADDITION AMONG SMALLHOLDER SWEET POTATO FARMING HOUSEHOLDS IN EBONYI STATE, NIGERIA

Smallholder farmers play a crucial role in sweet potato production, but limited value addition hinders their income generation and market participation. This study explored the factors that smallholder farmers in Ebonyi State considered when adding value to their sweet potato production. Using a multi-stage sampling technique, primary data was gathered from 400 small-scale sweet potato growers out of the state's 380,000 growers. Interview schedules were the instrument utilized for data collection. Information was gathered on the sweet potato processing method as well as the socioeconomic traits of the growers. Statistics from the descriptive and probit regression models were used to analyze the data. Findings revealed that the traditional method of processing sweet potatoes was predominant in the area. At a 1% probability level, the probit regression coefficient of educational attainment and farmers’ association membership was significant and positively correlated with the addition of value to sweet potatoes. Additionally, at a 5% probability level, access to credit was substantial and positively associated with the addition of value to the sweet potato. At 1% and 5% probability levels, respectively, coefficients of gender and farming status were significant and inversely associated with the addition of value to sweet potatoes. The study concludes that the most common processing methods used by sweet potato farmers are traditional processing methods. Therefore, strategies to educate farmers about the value of forming farmer groups are needed, as most training on value addition and access to knowledge about market opportunities can be easily shared through farmers' groups.

The impact of humic acid compound fertilizer on sweet potato variety Jishu 25: A comprehensive study on dry matter, root yield, and starch properties

In recent years, although humic acid (HA) compound fertilizers have been applied in sweet potato production, limited research has specifically addressed their impacts on dry matter (DM) accumulation, starch yield and starch properties, particularly in varieties with high starch content. To assess these effects, five treatments were designed for the high-starch variety Jishu 25 as follows: no fertilizer application (CK), chemical fertilizer with 75–60–180 kg ha−1 N-P2O5-K2O (F1), 750 kg ha−1 HA compound fertilizer with 2.6 % HA and 10–8–24 N-P2O5-K2O (F2), chemical fertilizer with 112.5–67.5–157.5 kg ha−1 N P2O5 K2O (F3), 750 kg ha−1 HA compound fertilizer with 3 % HA, and 15–9–21 N-P2O5-K2O (F4). The results indicated that F2 and F4 reduced the DM distribution ratio in leaves and stems, concurrently increasing DM accumulation in tuberous roots compared to F1 and F3. These HA fertilizer treatments enhanced the activities of AGPase, UGPase and SSS in tuberous roots during the middle and late growth stages, resulting in elevated total starch content and amylopectin content at harvest. Both types of HA fertilizers decreased the D [4,3] of starch particles, but exhibited minimal effects on PV, HPV, CPV, To, Tc and ΔH. The highest tuberous root yield and starch yield were observed after applying F2 continuously for two years. In conclusion, for optimizing starch yield while preserving its quality, the application of 750 kg ha−1 HA compound fertilizer with 2.6 % HA and 10–8–24 N-P2O5-K2O proved to be most advantageous for sweet potato producers cultivating this high-starch variety in regions with a similar climate in northern China.

Control measure of sweet potato weevil (Cylas formicarius Fab.) (Coleoptera: Curculionidae) in endemic land of entisol type using mulch and entomopathogenic fungus Beauveria bassiana

Abstract Sweet potato weevil Cylas formicarius (Fab.) is the main obstacle for sweet potato production in various countries. Root damage caused by C. formicarius larvae reduced root yield up to 100%. The aim of this study is to test the measures using mulch and entomopathogenic fungus Beauveria bassiana for controlling C. formicarius in endemic land of entisol type. The control measure tested was the use of straw mulch and plastic mulch as well as the application of the entomopathogenic fungus Beauveria bassiana. The research was conducted at the experimental station at Indonesian Legumes and Tuber Crops Research Institute, Malang from July to December 2018. The results showed that the measure for controlling C. formicarius using straw or plastic mulch combined with the entomopathogenic fungus B. bassiana produces root yields between 17 and 26 t/ha. Using plastic mulch as a cover for mounds with the application of the fungus B. bassiana is more effective and efficient in controlling C. formicarius than the insecticide deltamethrin. Plastic mulch can physically inhibit the process of laying eggs and the formation of C. formicarius larvae, while B. bassiana is toxic to eggs, larvae, and adults of C. formicarius. The efficacy of control measure using plastic mulch and the application of B. bassiana can reduce yield losses by up to 96.76%. Technological innovation using plastic mulch to cover the mound with the application of the entomopathogenic fungus B. bassiana can be recommended to control C. formicarius on land endemic to the entisol type.

PRODUCTION OF SWEET POTATO (Ipomoea batatas (L.) Lam) IN AGROFORESTRY SYSTEM: CASE STUDY OF AN EXPERIMENTAL UNIT IN SANTARÉM, PARÁ, BRAZIL

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.

Research Progress in the Mechanisms of Resistance to Biotic Stress in Sweet Potato.

Sweet potato (Ipomoea batatas (L.) Lam.) is one of the most important food, feed, industrial raw materials, and new energy crops, and is widely cultivated around the world. China is the largest sweet potato producer in the world, and the sweet potato industry plays an important role in China's agriculture. During the growth of sweet potato, it is often affected by biotic stresses, such as fungi, nematodes, insects, viruses, and bacteria. These stressors are widespread worldwide and have severely restricted the production of sweet potato. In recent years, with the rapid development and maturity of biotechnology, an increasing number of stress-related genes have been introduced into sweet potato, which improves its quality and resistance of sweet potato. This paper summarizes the discovery of biological stress-related genes in sweet potato and the related mechanisms of stress resistance from the perspectives of genomics analysis, transcriptomics analysis, genetic engineering, and physiological and biochemical indicators. The mechanisms of stress resistance provide a reference for analyzing the molecular breeding of disease resistance mechanisms and biotic stress resistance in sweet potato.

Development of thermoultrasound assisted blanching to improve enzyme inactivation efficiency, drying characteristics, energy consumption, and physiochemical properties of sweet potatoes

Thermoultrasound (USB) as a promising alternative to traditional hot water (HWB) blanching was employed to blanch sweet potatoes and its influence on enzyme activity, drying behavior, energy consumption and physiochemical properties of sweet potatoes were investigated. Results showed that successive increases in blanching temperature and time resulted in significant (p < 0.05) decreases in PPO and POD activities. Compared to HWB, USB led to more effective drying by promoting texture softening, moisture diffusion, microstructure alterations, and microchannels formation, which significantly reduced energy consumption and improved the overall quality of the dried sample. Specifically, USB at 65 °C for 15 min improved water holding capacity and ABTS, while USB at 65 °C for 30 min improved color (more red and yellow), total phenolic content, total carotenoid content, and DPPH. Unfortunately, blanching process showed detrimental effects on the amino acid composition of dried samples. Overall, the development of thermoultrasound assisted blanching for sweet potatoes has the potential to revolutionize the processing and production of high-quality sweet potato products, while also improving the sustainability of food processing operations.

Application of potassium fertilizer and plant growth regulators to the growth and productivity of purple sweet potato

The study aimed to determine the effect of plant growth regulators and potassium fertilizer on the growth and productivity of three clones of purple sweet potato. The experiment was conducted at IPB University experimental station in Leuwikopo Dramaga Bogor for seven months. The study used a split-plot design with three factors and three replications. The first factor was as a subplot, namely plant growth regulators (PGR) application which consisted of two levels of without PGR (S0) and with PGR (S1) concentration of 2 cc l-1 of water (2,000 ppm). The second factor was as a subplot, namely rates of potassium chloride fertilizer (60, 120, 180 kg ha-1 K2O). The third factor as the main plot was sweet potato clones of (K1) Ayamurasaki, (K2) RIS-03063-05, and (K3) MSU 03028-10. The concentration of 2,000 ppm PGR did not significantly affect growth and tuber yield components. Potassium chloride K2O of 60 kg ha-1 up to 180 kg ha-1 did not significantly affect growth and tuber yield components. MSU 03028-10 clone had the highest total tuber yield (1537.8), healthy tuber (1529.9), unmarketable tuber (740.3), and small tuber (709.0). MSU 03028-10 clones have the longest stem length and the largest number of leaves 3-12 WAP. This study indicates that the MSU 03028-10 clone produces better growth and productivity than other clones.

Effect and Mode of Different Concentrations of Citrus Peel Extract Treatment on Browning of Fresh-Cut Sweetpotato.

Browning is one of the main phenomena limiting the production of fresh-cut sweetpotatoes. This study investigated the anti-browning effect of citrus peel extracts and the key components and modes of action associated with browning in fresh-cut sweetpotatoes. Five different concentrations of citrus peel extract (1, 1.5, 2, 2.5 and 3 g/L) were selected to ensure storage quality; and the physical and chemical properties of fresh-cut sweetpotato slices were analysed. A concentration of 2 g/L of citrus peel extract significantly inhibited the browning of fresh-cut sweetpotatoes. The results showed that the browning index and textural characteristics of fresh-cut sweetpotatoes improved significantly after treatment with citrus peel extract; all the citrus peel extract solutions inhibited browning to some extent compared to the control. In addition; LC-IMS-QTOFMS analysis revealed a total of 1366 components in citrus peel extract; the evaluation of citrus peel extract monomeric components that prevent browning in fresh-cut sweetpotato indicated that the components with better anti-browning effects were citrulloside, hesperidin, sage secondary glycosides, isorhamnetin and quercetin. The molecular docking results suggest that citrullosides play a key role in the browning of fresh-cut sweetpotatoes. In this study, the optimum amount of citrus peel extract concentration was found to be 2 g/L.

Sweetpotato cultivation: characteristics, constraints and preferred traits of producers and consumers in Côte d'Ivoire.

In an environment where the adoption of improved varieties resulting from plant breeding programs is limited, it is essential to identify end-user preferences beforehand. A participatory survey was conducted in eight localities in Korhogo and Bouaké regions (central and northern Cote d'Ivoire respectively) to identify producers' preferences and increase the adoption of improved varieties. The study involved 160 producers and consumers through focus group discussions and individual interviews. Sweetpotato is mostly grown on small plots (<1 ha) of land (89.2%), with women (66%) as the main producers. In the Bouaké region, sweetpotatoes are grown on mounds (100%), whereas in Korhogo they are grown on ridges (86.2%). The main food products or forms of preparation from roots are fries (34.7%), boiled (34.3%), mashed (12.4%), and sweetpotato stew (9.1%). Major constraints, including low price of roots (26.3%), low productivity (16.2%), and post-harvest storage issues (14.5%), were identified as affecting sweetpotato production. The selection of new varieties should be oriented towards high-yielding varieties with high dry matter content, deployed stems, and roots of round, oblong, or elliptical shape with good culinary characteristics (dry matter, sweet taste, dry texture, absence of fiber). Plants must be drought resistant, be tolerant to poor soil, diseases, and pests, and have a good yield. The color of skin and flesh of the sweetpotato, although constituting criteria of choice, are not essential for the acceptance or the rejection of a variety by users. © 2023 The Authors.

Combined Application of Filter Cake and Macadamia Husk Compost Affects Soil Fertility and Plant Mineral Content of Orange-Fleshed Sweet Potatoes

A greenhouse pot experiment was conducted to investigate the influence of the combined application of filter cake and macadamia husk compost (FC+MHC) on the soil fertility and dry matter partitioning of Beauregard and 199062.1 cultivars of orange-fleshed sweet potato. The effects of the two organic wastes on the mineral nutrients in the leaves and the storage roots of the 199062.1 cultivar were also investigated. In addition to FC+MHC, four other treatments—filter cake only (FC), macadamia husk compost only (MHC), inorganic fertilizer only (IF), a combination of filter cake and inorganic fertilizer (FC+IF), a combination of macadamia husk compost and inorganic fertilizer (MHC+IF), and a control (CONT)—were included in the investigation for the purpose of comparison. To achieve this, 1 kg of compost was homogenized with 20 kg of soil and filled into graduated 25 L buckets. The experimental design was completely randomized. The plants were grown for 4 months. The results indicated that all treatments altered the soil fertility positively. There were indications that both filter cake and macadamia husk compost inhibited the absorption of iron (Fe), copper (Cu), and aluminum (Al). Also, zinc (Zn) and phosphorus (P) deficiencies in the initial soil were corrected after the application of the organic wastes. In terms of yield, FC+MHC was better than all other treatments. The outcome of this study will no doubt greatly benefit the resource-poor farmers of Northern KwaZulu-Natal who are involved in the production of orange-fleshed sweet potatoes.

Seventy years of sweet potato [Ipomoea batatas L. (LAM)] research in South Africa

AbstractThe 2030 Agenda for Sustainable Development Goals of the United Nations puts forward a transformational vision to cope with food security, nutrition, and health challenges, in which sweet potato can play an important role. Globally, sweet potato production is valued at $53.83 billion. The Agricultural Research Council of South Africa (ARC) sweet potato research and development (R&amp;D) program over the past seven decades delivered 31 genetically improved cultivars via demand‐led breeding, managed the collection and maintenance of 375 accessions, contributed toward the optimization of cultivation practices, developed crop protection and diagnostic services, and provided streamlined seed systems and technology transfer in processing and enterprise development. The ARC's work is part of a large number of interdependent global programs committed to improving livelihoods and nutrition through sweet potato. This review shares and analyses major achievements, highlights unique research contributions achieved through partnerships, and discusses bottlenecks on funding and uptake of technologies. New research imperatives will involve root phenotyping, employing marker‐based technologies, and genome‐wide association studies through new funding received recently. Exploration of the commercialization potential of processed products made from orange‐fleshed sweet potato will be a major focus of the R&amp;D program. Expansion of partnerships, marketing, and financing will be important for future contribution of sweet potato to the economy.

Correlates and Determinants of Involvement in Sweetpotato Production among Farming Households in Niger-Delta Area of Nigeria

Information on determinants of involvement in sweetpotato production (SPP) in Niger-Delta Area of Nigeria is scarce. Determinants of involvement in SPP among farming households in Niger-Delta Area of Nigeria were therefore assessed. Multi-stage sampling procedure was used to select 330 respondents. Data were collected through structured interview schedule and analysed using descriptive statistics, Chi-square, Pearson Product Moment Correlation-PPMC and logistic regression. Age and household size of respondents were 42.9±11.9 years and 8.7±5.5 persons, respectively. Most respondents were female (53.3%), while 94.5% had no extension contact. Farming experience and farm size were 21.1±12.9 years and 5.4±5.1 ha, respectively. Employed labour per sweetpotato (SP) production cycle, SP farm size and farming experience were 8±6 persons, 2.6±3.5 ha and 18±12 years, respectively. Income from SP, other crops enterprises and non-crop livelihood activities were N2 637 552.0±3 362 512.0 yearly, N5 283 845.0±6 147 413.0 yearly and N1 733 562.0±2 175 223.0 yearly, respectively. Most respondents (56.4%) produced above one cycle per year. Limited knowledge on processing of SP (x ̅=1.88) was the major constraint to SPP. Above half (51.8%) of the respondents had low involvement in SPP. Gender (x2=6.79), household size (r=0.12), farm size (r=0.19), farming experience (r=0.12) and income from SP (r=0.19) were significantly related to level of involvement in SPP. Government and other stakeholders should organise intervention (training and workshop) on increasing income from sweet potato production.

Climate Change and Sweet Potato Production; Empirical Insights from Ebonyi State, Nigeria

Climate change poses significant challenges to agriculture and land productivity particularly in regions heavily dependent on rain-fed agriculture like Ebonyi State, Nigeria. This study analyzed the effects of climate change on sweet potato production in Nigeria. Multi-stage sampling procedure was used to select 301 respondents. The drafted questionnaire was used for data collection following the specific objectives of study. Descriptive statistics, land productivity model, and multiple regression model were used for the data analysis. Results revealed that the majority of respondents (64.1%) were males, married (73.1%), young (42.2%), experienced (55.5%) and relatively educated (49.8%) with household and farm sizes of 7 and 1.8 hectares. The majority of the farmers (41.5%) were aware of changes in climate. Farm sizes of 1.1-2.0 hectares produced the highest land productivity (1769.831 hectares) in the state from about 51.5% of the farmers. Rising temperature, rainfall, and number of rainy days, influenced sweet potato production negatively; while sunshine hours and relative humidity had significant positive influences. Poor access to extension and services, land fragmentation, capital, inadequate information concerning climate change, and high cost of input resources constrained potato cultivation. The study recommends farmers to practice climate smart agricultural techniques and to seek early climate change information to mitigate negative effects of changing climate on sweet potato production.

Experiment of stem cutting planting position in increasing sweet potato (Ipomea batatas L.) production in horticulture learning

This study aimed to discuss: (1) the effect of different positions of stem cuttings on sweet potato production; and (2) whether this practical experiment-based approach is effectively implemented in horticulture learning. This experimental research used a completely randomized design. The population was sweet potato plants. The research sample was the tip cuttings of sweet potato plants. The length of the cuttings was 30 cm, measured from the tip of the plant’s stem with relatively the same number of segments. The number of treatments was 3: upright Po (180°), inclined P1 (45°) and flat P2. The number of repetitions was six times, and the number of samples for each treatment was 20 cuttings of the sweet potato stem tips. Thus, the number of sweet potato stem tip cuttings needed in this study is 3 X 6 X 20 cuttings = 360 (three hundred and sixty). Based on the ANOVA test, a significant value of 0,005 was obtained, far smaller than the determined significance level of 0,05. It means there is a significant difference between the weights of sweet potato tubers between treatments. In conclusion, there is a significant difference between the upright/90° and slanted/45° treatment and between the upright/90° and horizontal treatment. Meanwhile, the treatment between slanted/45° and horizontal showed no significant difference. Overall, the best sweet potato production is obtained by planting horizontally with an average tuber weight of 313 grams. It can be concluded that this practical experimental method is very effectively implemented in the horticulture learning process.

Analysis of Heat Transfer and Efficiency of Rack Type Flash Dryer Machine in Purple Sweet Potato Drying Process

Purple sweet potato (Ipomoea batatas var Ayumurasaki) has deep purple flesh and tuber skin. The variety of processed purple sweet potato products is increasingly diverse as purple sweet potato production increases, such as cookies and chips. Therefore, a process is needed to turn purple sweet potato into flour before being made into a variety of processed products, namely the drying process. Drying is a process of reducing the water content of a material to a certain level. To determine how much fuel is used by dryer machine, it is necessary to evaluate the effectiveness of the machine. So that in this study the aims were to determine the amount of energy needed to dry purple sweet potatoes, calculate the efficiency of the flash dryer machine and find out the temperature distribution on each tray of the drying machine. Based on the research results of the rack-type flash dryer drying machine, it can be concluded that the mechanism of the heat transfer rate in the purple sweet potato drying process occurs by forced convection heat transfer from the drying air to the purple sweet potatoes and a mass flow rate value of 0.1272 kg/s is obtained, the convection transfer rate in the drying chamber is 836.84 W and the sensible heat value is 1033.84 W. Hence, the amount of heat to dry 3 kg of purple sweet potato for 4 hours is 1870.68 W and an efficiency value of 55.26% is obtained. The total energy required to dry 3 kg of purple sweet potato in 4 hours is 5712.86 kJ.
