Full textAbstract:
Potatoes regarding their consumption are a significant antioxidant source in human nutrition. The main potato antioxidants are polyphenols, ascorbic acid, carotenoids, tocopherols, -lipoic acid, and selenium. The most contained polyphenolic antioxidants in potatoes are L-tyrosine, caffeic acid, scopolin, chlorogenic and cryptochlorogenic acid and ferulic acid. In red and purple potatoes are in addition contained acylated anthocyanins and pigmented potatoes display two to three times higher antioxidant potential in comparison with white-flesh potato. Red potato tubers contain glycosides of pelargonidin and peonidin, purple potatoes glycosides of malvidin and petunidin. New red and purple flesh potato varieties are breeded for their use in food and in the non-food industry. Anthocyanins of potatoes are also useful in the protection against potato blight.

Potato farming has been developed by the Tengger Tribe in Ngadisari Village, Sukapura District, Probolinggo Regency. These tribal people cultivate various agricultural commodities, but they feel prestige when farming potatoes. This prestigious perception underlines the research that aims: 1. To determine the existence of the prestigious perception, 2. To analyze economically whether potato farming supports the prestigious perception that it can provide higher profits than other plants cultivated on the same land, and 3. Are there socio-cultural reasons for the prestigious perception of potato farming. This study used quantitative methods with 30 respondents selected by purposive sampling. The description method used to know the existence and identify social-cultural factors of the prestigious perception. To prove that economically, analyzed by comparing the potato’s farming income with non-potato on the same land. The result showed: 1) 77 % of respondents still feel prestige if they cultivate potatoes, 2) economically, potato farming had a higher income than non-potato farming, and 3) socio-cultural factors that support Tengger Tribe feel prestige: a. passed down from generation to generation, b. farming complexity challenges, and c. the needs and equality of female workers.

The Potential of Euphorbia heterophylla as an Alternative Host of Scab Disease on Sweet Potatoes. Scab, caused by Elsinoë batatas (Saw.) Jenkins & Viegas, is a major disease on sweet potato. The disease cause reduction in tuber production up to 30%. Euphorbia heterophylla is one of the common weeds in the cultivated land of sweet potatoes which is considered as an alternative host plant of the scab. The objective of this research was to study the ability of E. heterophylla as an alternative host of sweet potato. This study consisted of identification of sweet potatoes scab symptoms and E. heterophylla spot symptoms, isolation of the pathogen of sweet potato scab and E. heterophylla spot, and the test of pathogen virulence on some sweet potato cultivars. The result showed that the scab symptoms on sweet potatoes was brown and concaved caused by fungi E. batatas, while the spot symptoms on the E. heterophylla was white and convex caused by Fusarium sp. The cultivar of sweet potatoes which were inoculated with sick sweet potatoes suspension showed scab symptoms, however no symptoms occurred on the sweet potatoes which were inoculated with suspension of E. heterophylla. Overall, E. heterophylla was not considered to be the alternative host of scab on sweet potatoes.

Analysis of potatoes and potato products foreign trade was conducted in changing market and trading conditioning before and after the Polish accession to the EU and in last years, when adaptation processes in the Polish potato sector practically were already finished. In spite of the biggest decrease in last years, Poland still remains one of the bigger producers of potatoes in Europe and in the world. The export of potatoes to the direct consumption is low, however the sale to of potato products to foreign markets systematically grows, mainly of fries and chips, what is possible thanks systematically increasing their domestic production. After the Polish accession to the EU and for abolishing tariff barriers an import of potatoes and potato products considerably increased. Poland has a positive balance in potato products foreign trade, however from the accession to the EU remains the net importer of potatoes.

Full textAbstract:
This article focuses on an examination of the possibility of using potatoes as a binder in the production of heating pellets from flax stalks. This research was carried out in the form of an experimental production, laboratory analyses, and combustion tests of pellets with the Biltstar variety of flax stalks. The production was carried out using an MGL 200 pelletizing line. Adéla potatoes were used as a binder at a dose of 10%. The results were compared to the control variant without the addition of potatoes. Potatoes had a positive effect on the mechanical properties of the pellets as well as on carbon monoxide emissions. A positive effect of the addition of potatoes was recorded by an increase in specific weight (599.2 kg/m3 for the potato-free variant and 1092.3 kg/m3 for the variant with potatoes) and a significant increase in mechanical durability (4.39% for the potato-free variant and 0.71% for the variant with potatoes). The biggest difference was measured in carbon monoxide emissions (13,082 mg/m3N for the potato-free mg/m3N ariant and 5186 mg/m3N for the variant with potatoes). The values were converted to a reference oxygen content of 10%.

Full textAbstract:
Postharvest handling of the potato is an important factor not only in preventing postharvest losses but also in maintaining its safety and nutritional quality. Exposure of the potato to unfavorable conditions such as light, extreme temperatures, and bruising can result in accumulation of glycoalkaloids, which are toxic substances. This study was a cross-sectional survey which aimed to investigate the postharvest handling practices of potatoes and perception of potato safety among open air market traders in Nairobi County, Kenya. Information was collected from 100 potato traders using a semistructured questionnaire that assessed postharvest handling practices such as potato transportation, exposure to sunlight, and storage. Results indicated that most of the potatoes (88%) took one day to be transported to the market, with the storage period at the market ranging from 2 to 3 days for most traders (42%). Forty-seven percent (47%) of the vehicles and hand-pulled carts used to transport potatoes had open backs, while 53% had closed backs. Over half (69%) of the potatoes in the markets were directly exposed to sunlight, with 75% of the traders leaving their potatoes in the open covered with a polythene bag after the day’s activities. Greening, sprouting, or bruised potatoes were mostly sold as seed, sold to restaurants and French fries vendors, or sold to consumers at a lower price. More than half of the traders did not think that consumption of greened potatoes is harmful to health. The results clearly show that there is poor handling of the potatoes by the traders which increases the risk of consumer exposure to glycoalkaloids. There is, therefore, a need to create awareness among traders on appropriate postharvest handling of potatoes to protect consumer health and reduce economic losses as well.

Full textAbstract:
AbstractThe population dynamics of the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Pyralidae), were documented on potatoes grown in Prince Edward Island (P.E.I.) from 1990 to 1992. By comparing degree-day accumulations above 10°C, both first occurrence and peak flights of male adults occurred earlier than elsewhere in North America. Because potatoes in P.E.I. are attacked earlier and over a longer period of time than potatoes grown in other regions, the insect is an important pest of potatoes in P.E.I. The correlation between peak numbers of male adults caught in pheromone traps and egg masses on potato plants was not significant (p = 0.22). However, the correlation between egg masses per potato stalk and larvae per potato stalk was significant (p = 0.003). Trapping adults and monitoring potato plants for the presence of egg masses during the period from 250 to 500 degree-days appears to be a reliable way to determine the presence of adults and the potential impact of larvae on yield of potatoes.

Potato, or as it is called the “bread of the poor”, is a traditional product and the fourth world's largest consumption culture after rice, wheat, and maize. Potato contains vitamin B6 (32%), starch (26%), copper (22%), vitamin C (22%), magnesium (19%), phosphorus (17%), fiber (15%), pantothenic acid (13%), and other ingredients. Americans eat on average 35 kg of frozen potatoes per year: 19 kg of fresh potatoes; 8 kg of potato chips; and 6 kg of dehydrated potato products. The global monthly consumption of potato per capita is 31.3 kg. A greater consumption per capita is in Europe with 87.8 kg/capita. Residents of cold countries of Eastern Europe are the biggest consumers of potatoes in the world. China is the largest producer in the world (75mil / year), but it is not the largest consumer per capita. The volume of international potato trade is smaller than the volume of production. Only 6% of potato production reaches trade market worldwide. Trade in processed potatoes is increased, and with higher rates exceed fresh potato trade. It passes from fresh consumption to processed consumption. Developed countries are those which provide markets with these processed products, earning high rate of profits. Processed potatoes make up 64 percent of total US potato consuming. Kosovo has a great potential to produce potatoes, but there are some obstacles such as small domestic consumption and the market in general. In this article, the factors that affect consumption are explored, which as a consequence increase the production.

Full textAbstract:
Today, the demand for horticultural commodities is relatively high, making these commodities more important in the growing Indonesian economy. One of the horticultural commodities is the potato (Solanum tuberosum). Potatoes are widely used as ingredients in the light meal industry such as potato chips. Restaurants and fast food industry also use potatoes as the ingredients. Wonosobo regency is one of the areas in Java producing a lot of potatoes and the majority of the population work as farmers. The purpose of this research is to find out the network design of potato supply chain in Wonosobo regency in order to design a more effective and efficient one. This research uses the descriptive qualitative method and the processes of collecting data are observation, interview, and documentation. The results suggest that the current supply chain design of potatoes is from farmers, middlemen, retailers, and consumers. An alternative network design proposed is the farmers should channel the lower quality potatoes directly to the retailers. While another alternative is, for the good quality potatoes, the farmers should sell them to cooperative for export.

Full textAbstract:
Abstract A liquid chromatographic (LC) method was developed for determination of thiabendazole (TBZ) residues in or on whole, unwashed white potatoes (Solarium tuberosum) and sweet potatoes (Ipomoea batatas). TBZ is extracted from the potato homogenate with ethyl acetate and the extract purified and concentrated on a cation-exchange, solidphase extraction column. The extract is analyzed for TBZ residues by column LC with a cation-exchange column and fluorescence detection. Recoveries of TBZ from whole white potatoes fortified with TBZ at 0.05–20 ppm and from whole sweet potatoes fortified with TBZ at 0.005–0.1 ppm averaged 100 and 94%, respectively. The method is also applicable for quantitation of TBZ residues in white potato waste (dried peel) used as an animal feed additive. The present method for monitoring TBZ residues in white and sweet potatoes and white potato waste (dried peel) is simple, rapid, and sensitive.

Full textAbstract:
Sweet potato is a local food that can reduce dependence on rice and flour consumption. It is the main source of carbohydrates, after rice, cassava, flour and corn. The benefits and potency of sweet potatoes as alternative food needs to be developed, especially in rural areas. However, sweet potato has not been considered as an important and high economic value commodity in Indonesia. Sweet potatoes have been used as food and non-food raw materials in developed countries i.e. noodles, fried sweet potatoes, desserts, confectionery, soy sauce, flour, wine, vinegar, nata de coco, bioethanol and others. Around 89 % of sweet potatoes in Indonesia are cultivated for providing food to rural communities, the rest are used for industrial raw materials and animal feed. The content of sweet potatoes includes carbohydrates, vitamins, and minerals. Yellow/orange sweet potato is rich in beta-carotene and purple sweet potato contains anthocyanin (antioxidants). Sweet potato production is still limited to traditional food that is less attractive compared to flour products. Meanwhile, intermediate products have been developed including flour, instant flour, and starch that can be used as a substitute for flour in pastry products, wet cakes, breads, and noodles.

Full textAbstract:
Potato tubers were collected and evaluated for symptoms and signs of black dot, silver scurf, and Verticillium wilt to determine the effect of extended crop rotations on disease incidences in the Columbia Basin. Incidence of tubers with black dot collected from storage significantly decreased as the number of years between potato crops increased from 3 to 5 years and beyond and significantly increased as the number of previous potato crops increased to 16. The highest incidence of black dot (range of 73 to 98%) was from fields rotated out of potatoes for 1 to 3 years. The mean incidence of black dot was 56% for fields out of potatoes for 0 to 4 years and 12% for fields out of potatoes 5 and more years. A low incidence (0 to 9%) of black dot was detected at 15 years out of potatoes. Years out of potato and number of prior potato crops accounted for 71% of the variability associated with the incidence of black dot. Severity of black dot on tuber periderm peels significantly increased as incidence of tuber periderm peels with Colletotrichum coccodes increased. Coefficient of determination was 0.87 for log severity on regressed on black dot incidence. Incidence of silver scurf was highest from fields out of potatoes for 1 year. Incidence of silver scurf infected tubers significantly increased as the number of previous potato crops increased due to short rotations between potato crops. Incidence of tubers with Verticillium dahliae was not related to years between potato crops or number of previous potato crops. The present study confirmed that black dot can be reduced with rotations out of potatoes greater than 5 years.

Potatoes (Solanum tuberosum L.), one of seven horticultural products targeted to be developed in 2015 by Directorate General of Horticulture. Pasuruan Regency was be able to produce potatoes up to 50% of the total potato production in East Java. Although potatoes cultivation in the Tosari District is relatively large, potatoes productivity is still a problem for the farmers. This study was aimed at analyzing the factors of production that had a dominant influence on potato production and its technical efficiency in the Tosari Village, Tosari District, Pasuruan Regency. Sample was determined by simple random sampling and amounted to 30 potato farmers. Data were analyzed with multiple linear regression models. Analysis revealed that the significant factors affecting potato production in Tosari Village were urea, SP36, ZA and manure. Application of urea, ZA and manure in potato farming in Tosari Village had not been efficient, so it can be added. Meanwhile, SP36 fertilizer was still applied inefficiently, so it must be reduced..

For ensuring the food security and maximum use of land, the potato production under a mango-based agroforestry system is an effective production approach. The purpose of this study was to assess the yield potential and the economic benefits of potato production under a mango-based agroforestry system. The potato tubers were planted in a 10-year-old mango orchard and open field condition. The experiment was laid out following a split plot design with three (3) replications. Potato production system under mango orchard and open field were arranged in main plots T0 = potato sole cropping (control) and T1 = potato under mango-based agroforestry system. On the other hand, potato intra-row plant spacing were in sub-plots S0 = 60 × 20 cm2, S1 = 60 × 25 cm2 and S2 = 60 × 30 cm2. The data of yield characters of potatoes were investigated. The cost of production, gross & net return and benefit-cost ratio was calculated for economic analysis. The results show that the closest (60 x 20 cm2) intra-row plant spacing produced the highest yield while the economic returns from potatoes grown under the mango-based agroforestry system were higher than those derived from cropped grown as a sole crop or potatoes cultivation alone (gross returns US$3508/ha, net returns US$1642/ha). Further, the benefit-cost ratio from the combined cultivation of potatoes and mangos was 2.14, which was 20 % higher than growing potatoes as a sole crop. Thus, the cultivation of potatoes under a mango-based agroforestry system offers a significant financial benefit to farmers while ensuring the sustainable use of vacant space in mango orchards

After more than 10 years of research, Monsanto scientists have developed improved seed potatoes that are protected from serious pests, including insects and disease. The first commercial products resulting from this effort were NewLeaf ® potatoes derived from `Russet Burbank' and `Atlantic' parents. The NewLeaf® product was commercialized in 1995 and contains a gene from Bacillus thuringiensis (variety tenebrionis) (B.t.t.). for the production of the Cry3A protein. Potatoes expressing this gene are completely protected from the Colorado potato beetle (CPB) and need no additional chemical protection for this insect pest. The U.S. Food and Drug Administration (FDA), U.S. Dept. of Agriculture (USDA), and U.S. Environmental Protection Agency (EPA) have all determined that these potatoes are the same in safety and nutritional composition as any other `Russet Burbank' and `Atlantic' potatoes. These potatoes have also been approved by Health Canada, Agri-Food Canada and Agriculture Canada and by Japan and Mexico for food use. Commercial growers across North America have experienced outstanding performance while growing NewLeaf® potatoes 3 years in a row. This level of performance is the result of stable, nonsignificant differences in expression of the Cry3A gene. The stable performance, also, is a result of an effective insect resistance management program based on maintaining CPB refuges near NewLeaf ® fields, reducing CPB populations, and monitoring for CPB surviving exposure to NewLeaf® potatoes. In 1998 NewLeaf Y®), conferring resistance to both CPB and potato virus Y, and NewLeaf Plus®, conferring resistance to CPB and potato leafroll virus will be commercially released.

Early potatoes are mainly used for food. In tubers varieties early term maturation contains less starch, but they differ a good taste. Getting the potato harvest in the early days, when the range of domestic vegetables is not large is very important and can compete with imports. Potatoes have increased requirements for soil moisture. The transpiration coefficient of potatoes varies depending on meteorological factors, agro-technical measures, as well as on the varietal properties of the plant itself. Getting the potato harvest in the early days, when the range of domestic vegetables is not large is very important and can compete with imports. Potatoes increased the requirements for soil moisture. The risk of potato cultivation from uneven rainfall distribution during the growing season and from the difference in years can be reduced by using irrigation. Early potatoes, while ensuring all factors manages to give a good harvest on July 15 at harvest 30 July high yield. The use of irrigation can increase yields by 50.0–55.1 % depending on the term of harvesting tubers.

Full textAbstract:
In the supposed or proven incidence of bacterial ring rot caused by <i>Clavibacter michiganensis</i> subsp. <i>sepedonicus</i> (<i>Cms</i>) in certified seed and commercial potatoes, five periods can be identified in the Czech Lands from 1910 to 2006: (<i>i</i>) high incidence of <i>Cms</i> in potato crops is claimed (about 1910–1929); (<i>ii</i>) very low incidence in certified potatoes and sporadic occurrence in commercial potatoes (about 1930–1985); (<i>iii</i>) increasing incidence of <i>Cms</i> in certified seed potatoes and its sporadic occurrence in commercial potatoes is assumed (about 1986–1997); (<i>iv</i>) a relatively high percentage of potato tuber samples proved to be infected by <i>Cms</i>, namely 1.14% in seed potatoes in 1998 and 4.13% in commercial potatoes in 1999 (1998–2004 period); (<i>v</i>) progressive decrease of <i>Cms</i> incidence to zero in seed potato samples and 0.19% in commercial samples in 2005, followed by a slight increase to 0.15% in seed potatoes and 0.23% in commercial potatoes in 2006 (2005–2006 period). Thus, up to 2006, <i>Cms</i> was and is not widely distributed in the CR and is actively and effectively controlled, mainly through the zero tolerance for ring rot bacterium in the seed potato certification program. In the CR, <i>Cms</i> has a relatively low capacity for damage and can hardly be considered as a pest of national economic importance. Strictly speaking, <i>Cms</i> does not fulfill the criteria for a quarantine organism. If, however, the quarantine status of <i>Cms</i> will be maintained, the severe post-entry measures against it should be relaxed.

Potato (Solanum tuberosum) tubers contain vitamin C (VC) and commercial potato chips have more VC content per wet weight by dehydration during frying. However, intestinal absorption of VC from orally ingested potatoes and its transfer to the blood remains questionable. The present study was designed to determine whether the dietary consumption of potatoes affects VC concentration in plasma and urinary excretion of VC in human subjects. After overnight fasting, five healthy Japanese men between 22 and 27 years of age consumed 87 g mashed potatoes and 282 g potato chips. Each portion contained 50 mg of VC, 50 mg VC in mineral water and mineral water. Before and after a single episode of ingestion, blood and urine samples were collected every 30 min or 1 h for 8 h. When measured by subtraction of the initial baseline value before administration of potatoes from the values measured throughout the 8 h test period, plasma VC concentrations increased almost linearly up to 3 h. Subsequently, the values of potato-fed subjects were higher than those of water, but did not differ significantly from those of VC in water (P = 0·14 andP = 0·5). Less VC tended to be excreted in urine during the 8 h test than VC in water alone (17·0 (sem7·5) and 25·9 (sem8·8)v.47·9 (sem17·9) μmol/mmol creatinine). Upon human consumption, mashed potatoes and potato chips provide VC content that is effectively absorbed in the intestine and transferred to the blood. Clearly, potatoes are a readily available source of dietary VC.

Undesirable thermal processes or storage conditions lead to physical and chemical quality loss of every food. The objective of this study was to determine the total solid content, starch, reducing sugars, nitrates and nitrites in raw and thermal processed red and white potato samples purchased from different geographic origin in Croatia. The potatoes were processed with and without the skin, and cooking processes were carried out in classic way, in the pressure cooker and in the microwave oven. Standard methods of analysis for above-mentioned parameters were used. The results showed no significant influence (P < 0.05) of the geographic origin on investigated parameters in raw samples (except for nitrates), but there were significant differences (P < 0.05) in composition between the kinds of samples (red and white). Thus, samples of white potato had higher total solids, starch and reducing sugars content than red potato samples, while red potatoes had higher nitrites and nitrates content. Thermal treatment showed that the total solid content is higher in potatoes processed with skin then those processed without the skin. The starch content in both kinds of potatoes increased after thermal processes if potato was processed without skin. The content of reducing sugars was the highest in samples of raw potato. The nitrites and nitrates content were decreasing during thermal treatments. Thermal processing (classic way, under pressure or with microwaves) and the manner on which the potatoes were cooked (with or without skin) significantly influenced on all investigated parameters especially in red potatoes samples.

This study was conducted to find out the effect of sprouting inhibitors under different storage temperatures and reconditioning conditions on the processing quality of potato tubers produced in the alpine area of Korea. A higher sprouting ratio was observed in potatoes stored at 15°C than those at 5°C. In particular, 1% CIPC, was effective in the inhibition of sprouting, keeping the sprouted shoots in less than 2 mm, while rosette-shaped shoots, 12–17 mm, were observed in the CMH (100%) treatment. Atlantic was, in general, lower in reducing sugar contents compared to Superior. Reducing sugar contents in potatoes stored at 15°C were not increased, while potatoes stored at 5°C showed a 1% increase in reducing sugar contents for 180 days after storage. As far as chip color “L” value was concerned, no difference was detected among potato cultivars and sprout inhibitor treatments. Potato chip color was found to be the best from potatoes stored at 15°C for 180 days of storage. However, potatoes stored at 5°C gave rise to poor quality of potato chips with browning and bitter taste. Reconditioning had different effects on potato cultivars in that Atlantic potatoes produced more sprouts when they were reconditioned compared to the control of 15°C potato storage. In terms of the effect of reconditioning on reducing sugar contents, Atlantic sugar contents was reduced reconditioning went on. Sugar contents of Superior, however, was increased after undergoing the decrease for some time. Changes in potato chip color as influenced by reconditioning were in accordance with changes in reducing sugar. Atlantic was much better in chip color than Superior, showing a chip color “L” value of more than 50 in all treatments.

Full textAbstract:
Background: In sustainable crop production focusing on high-value products, biostimulants have been gaining increasing importance, thus the hypothesis that plant biostimulants could contribute to improving new potatoes quality; Methods: The effects of the seaweed extracts Bio algeen S90 (Ascophyllum nodosum) and Kelpak SL (Ecklonia maxima), as well as the humic and fulvic acids in HumiPlant (leonardite extract) on the tuber quality of very early potato cultivars (‘Denar’, ‘Lord’, ‘Miłek’) were investigated. Potatoes were harvested 75 days after planting (the end of June); Results: The biostimulants did not affect dry matter, protein, total sugars, monosaccharides and sucrose or L-ascorbic acid content in new potatoes. Bio-algeen S90 increased the starch content in tubers of all potato cultivars tested, on average, by 4.8 g∙kg−1 compared with control treatment without biostimulant, whereas Kelpak SL and HumiPlant reduced nitrates content only in tubers of ‘Denar’ cultivar, on average, by 8.50 mg∙kg−1, and increased ascorbate-nitrate index (IAN) by 0.29. The biostimulants did not affect potato after-cooking darkening. Both the nutritional value of new potatoes and after-cooking darkening depended on the cultivar and weather conditions during the potato growing period to a great extent; Conclusions: Plant biostimulants slightly affected quality of new potatoes.

The subject of the analysis was potato production, domestic consumption and foreign trade turnover (export and import) in Poland in 2001-2019. Based on the results of the analyzes, a medium-term projection (for 2025) was defined, covering production, directions of domestic use and foreign trade turnover of potatoes and their products. The analyzed data came from the Central Statistical Office and Institute of Agricultural and Food Economics- National Research Institute. Potato production in Poland in 2001-2019 was characterized by a downward trend. The slower drop in the harvest than in the area was due to the improvement in yield. There were various trends in domestic consumption: a decrease in total potato consumption, in the export of unprocessed potatoes, in processing in distilling and losses in storage, and an increase in food processing and other industrial processing. In foreign trade, an improvement in the positive balance of trade in potato products and a deepening of the negative trade balance in potatoes was observed. The development projection for 2025 shows that the production of potatoes in Poland may amount to 7,250,000- 7,540,000 thousand tonnes, and the demand – 7430 7570 thousand tonnes. The necessary import of fresh potatoes can amount to 30-180 thousand tonnes annually.

Potatoes are nutrient rich white vegetables, however, research on their impact on public health is limited. The objective of this study was to provide updated evaluation of the cross-sectional association between potato consumption and diet quality, nutrient intake and adequacy. Twenty-four hour diet recall data from adolescents (n = 16,633; age 9–18 years) were used to assess intakes. Usual intakes of nutrients were determined using the National Cancer Institute method and diet quality was calculated using the Healthy Eating Index-2015 (HEI-2015) after adjusting for demographic factors. Consumers of potatoes (baked or boiled potatoes, mashed potatoes and potato mixtures, fried potatoes, and potato chips) had higher (p < 0.05) HEI-2015 total score and subcomponent scores for total vegetables, total protein foods, and refined grain than non-consumers. Consumers also had higher (p < 0.05) intake of energy, dietary fiber, protein, copper, magnesium, phosphorus, potassium, selenium, sodium, zinc, niacin, vitamin B6, vitamin C, vitamin K and total choline; and higher (p < 0.05) adequacy for protein, copper, magnesium, phosphorus, potassium, zinc, thiamine, niacin, vitamin B6, vitamin C, and vitamin K than non-consumers. In conclusion, adolescent potato consumption was associated with higher diet quality, nutrient intake, and adequacy and therefore encouraging their consumption may be an effective strategy for improving nutritional status.

Abstract Objectives Potatoes are typically considered to be less healthy than most vegetables although the 2015 Dietary Guidelines provide no specific recommendations for intake other than to reduce consumption of fried potatoes. Evidence linking potato consumption, including consumption of fried potatoes with a risk of obesity, is limited. The objective of the current analysis was to study the impact of potato consumption on the risk of obesity and elevated cardiometabolic risk (CMR) in adolescent girls. Methods We used data for 2091 girls, ages 9–10 years at enrollment in the prospective National Growth and Health Study (NGHS). and followed for 10 years. Potato consumption was derived from 3-day records collected during the annual follow-up periods. Total potato intake included white and sweet potatoes from all sources including mixed dishes. Total intake was classified as <0.25 (low), 0.25–<0.5 (moderate), and 0.5–<1.0 (high) cup-equivalents per day. Logistic regression models were used to estimate the odds ratio for becoming overweight or developing elevated blood pressure, triglyceride levels, or fasting glucose at 17–20 years of age according to the category of potato consumption. Models adjusted for confounding by factors such as age, race, socio-economic status, BMI, the hour spent watching TV per day, and other dietary factors. Results At 9–17 years of age, the median intake of total potatoes was 0.38 cups/day. Girls with moderate intakes of potatoes had a 23% lower risk (95% CI: 0.57–1.04) of being overweight (>85% ile of CDC cutoff values); the effects of higher intakes were the same. The odds ratio for elevated blood pressure (≥90th percentile for age, sex, height) associated with moderate (vs. low) intakes of potatoes was 1.16 (95% CI: 0.84–1.59) and again, the effects of higher intakes were very similar. For the relation between potatoes and elevated triglycerides (≥110 mg/dl), the risk was U-shaped with those who had moderate (vs. low) intakes having a 24% lower risk (95% CI: 0.54–1.08). Finally, moderate and higher (vs. lower) potato intakes were linked with non-statistically significant 26% and 30% reduced risks of elevated fasting glucose levels, respectively. Conclusions These analyses suggest that there is no adverse effect of moderate daily potato consumption on cardiometabolic risk in adolescent girls. Funding Sources The Framingham Heart Study.

The work presents the results of comparative field tests on effectiveness of insecticides and bioinsecticides and their tank mixtures for potatoes against the potato ladybird and the Colorado beetle in the South of the Far East. Effectiveness of preplanting and vegetation treatment of potatoes with preparations was observed. The study, conducted in 2012–2014 on the plants of the recognized Yantar potatoes variety, showed high biological efficiency of preparations from the neonicotinoid class of Prestige and Cruiser in the rates of 1.0 l/t and 0.2 l/t by pre-planting treatment of potato tubers. The Prestige and Cruiser provided long-term protective effect against the Colorado potato beetle and the potato ladybird, which eliminated the need for treatment in the growing season of the crop. The use of these insecticides caused productivity increase of potatoes by 7.5 and 8.4 t/ha. For vegetation treatment the preparation Decis Extra showed the highest and the most long-lasting effect. On the 28th day after the treatment, its effectiveness accounted for 84.4–90.3%. Protective effect of bio-insecticide Phytoverm lasted for 14 days. Double treatment of potatoes with this bio-insecticide restrained the number of pests below the threshold number until the end of the growing season. During the research it was found that the joint use of Phytoverm with 3 times lower rates of the insecticides Decis Extra and Konfidor provided a significant reduction in the number of the potato ladybird and the Colorado potato beetle and the preservation of 39.3-41.6% of potato productivity.

Conservation tillage using residue from a cover crop grown before potato (Solanum tuberosum L.) production has been infrequently and inconclusively studied. The objectives of this study were to 1) conduct a field study to evaluate soil physical properties, and potato growth and yield, in conventional-tillage (CT), no-tillage (NT), and subsurface-tillage (SST) systems and 2) conduct a greenhouse study to evaluate the effect of soil bulk density (ρb) on potato growth and yield. Potatoes (`Atlantic') were planted into residue of sorghum-sudangrass [Sorghum bicolor (L.) Moench × S. sudanense (Piper) Staph] at two sites in eastern North Carolina—Plymouth into Portsmouth fine sandy loam and Lewiston into Norfolk sandy loam. Potatoes in the NT and SST system emerged more slowly than potatoesplanted conventionally. There were no differences in plant population or size by 8 weeks after planting at Plymouth, but plant population and size were less in NT and SST systems at Lewiston. Reducing tillage also affected soil compaction, increased soil moisture early in the season at both sites, and increased ρb at Lewiston. Yield of U.S. No. 1 potatoes planted in NT and SST systems were comparable to potatoes planted in a CT system at Plymouth, but were less than potatoes planted in a CT system at Lewiston. There were no differences in yield between potatoes planted with NT and SST. In the greenhouse study, ρb did not affect leaf area or tuber yield or tuber grade. Specific sites and soils may allow for comparable potato production with no or SST, but further research, conducted on different soil types would promote further understanding of the impacts of reducing tillage in potato production.

OPTIMIZING THE SWEET POTATOES’ POTENTIAL IN SINDANGKARYA VILLAGE, MENES SUB-DISTRICT, PANDEGLANG REGENCY. Sweet potato is one of the agricultural commodities that is suitable for cultivation in Sindangkarya village, Pandeglang Regency. Each year, Sindangkarya village produces 350 tonnes of sweet potato. However, the low price of sweet potato causes small income for the residents. One of the efforts to increase its selling value is processing sweet potatoes into various products such as sweet potato cake or various other processed products. The problem founded is that people do not have the knowledge and skills of sweet potatoes utilization. The purpose of this community service activity is to transfer knowledge and train the community skills in processing sweet potatoes so they will have a higher selling value and attract the buyers. This article concludes that Sindangkarya Village has a business potential that involves the participants, PKK Cadres, Posyandu Cadres and Youth Organization developing creative ideas to make valuable products and beneficial to the lives of Sindangkarya residents and can reduce unemployment.

Fungi are considered serious pathogens to many plants and can cause severe economic damage. Early detection of these pathogens is very important and might be critical for their control. The available methods for detection of fungi are time consuming and not always very specific. Fourier transform infrared (FT-IR) microscopy has proved to be a reliable and sensitive method for detection of molecular changes in cells. Fungi pathogens display typical infrared spectra that differ from the spectra of substrate material such as potato. In the present study we used FT-IR microscopy for early and rapid detection of the potato fungal pathogen Colletotrichum coccodes on the surface of potato tubers. Infected potatoes with this fungal pathogen and uninfected potatoes were examined and correctly classified as infected or not infected by FT-IR microscopy at very early stages of infection when no morphological signs of infection could be seen. Unique spectral biomarkers were found in naturally infected potatoes compared to disease-free control potatoes.

It is possible to decompose starch into monosaccharides by the method of acid starch hydrolysis. By applying appropriate chemical procedure, a main solution is obtained, from which aliquots are taken after filtration to determine of the present glucose according to Luff-Shoorlu method. The analysed potatoes of cv. Desiree, grown on various sites in Serbia, have starch content that corresponds to available literature data. The highest starch content is found in potatoes from Ivanjica and Novi Pazar, i.e. from the areas where climate factors, air temperature, and land relief are favourable for potato growing. Lower starch contents are found in potatoes grown in flat areas with warmer climate and drier periods. Those are sites in PKB-Belgrade, Smederevo, Dobanovci and Mrcajevci areas, where the values obtained by experimental procedure are very similar. The lowest starch content is found in potatoes from Belegis and Guca sites, where starch content is lower than normal from literature values, which may be explained by some special causes (climate, location, irrigation). On the basis of heavy metal contents in potato samples, it may be concluded that potatoes originating from sites famous for potato production are contaminated with Cd the content of which exceeds concentrations permitted by regulations. The presence of Cd in potato samples may also be explained by the application of phosphate fertilizers in higher (or recommended) rates. However, the soil itself should also be investigated, especially concerning the content of Cd and pH value. Thus, the influence of the soil itself should be established compared to fertilizer application in the current season. Presence of Cd in potatoes, on the other hand, is highly unfavourable because it prevents its utilization in nutrition, but also as a raw material for further processing of products based on potatoes: chips, etc. Also, Cd presence in foods is strictly controlled by EU, which prevents possible export of products based on potatoes containing Cd. Analyses of lindane and bensultap (Bancol) pesticides indicate that they are not within critical values, nor in such quantities to affect human health, so, from this aspect, the analysed potato samples from all sites are absolutely suitable for consumation.

The most important problem of the introduction of advanced potatoes seed system is to protect against repeated infection the healthy potatoes by viruses in the open field. In our republic the greatest risk to re-infection the healthy potatoes seed is Y - potato virus. The principal vectors of Y – potato virus, developing the largest number, are three types of aphids - buckthorn (Aphis nasturtii), alder (Aphis frangulae) and bean (Aphis fabae). The bean aphid is dominant, in some years its size rises up to 2406 copies. Relatively low coefficient of harmfulness (0.1 equivalent unit), provided the mass settlement on the plants can significantly increase the contamination of potatoes seed. The climatic conditions of the growing season, precipitation, relative humidity, which significantly affect the development and dispersal of aphids on host plants are of great importance.

Dry matter (DM) content is one of the most important quality features of potatoes. It defines the physical properties of the potatoes and determines what kind of product the potatoes can be used for. This paper presents the results obtained by a novel prototype NIR (near-infrared) instrument designed to measure DM content in single potatoes in process. The instrument is based on interaction measurements to measure deeper into the potatoes. It measures rapidly, up to 50 measurements per second, allowing several moving potatoes to be measured per second. The instrument also enables several interactance distances to be recorded for each measurement. The instrument was calibrated based on three different potato varieties and the calibration measurements were done in a process plant, making the calibration model suitable for in-line use. A good calibration for DM was obtained by partial least squares regression (RMSECV = 0.78% DM, R2 = 0.91). The instrument was tested in-line in the process plant and several batches of potatoes were monitored for the estimation of the DM distribution per batch. Accuracy of DM determination as function of measurement position on the potato was studied, and results indicate that NIR scans along the center part of the potatoes give slightly better results compared to scans taken on either side of the center. Small differences in optical measurement geometry influence the accuracy of the calibration models, underlining the importance of optimizing instrument design for successful measurements.

Crop yields can be significantly increased by using pectic polysaccharides – natural ecologically safe and effective plant growth stimulants. In this paper, high growth-stimulating activity of pectins with respect to potatoes is shown. The research was conducted in 2012–2015 in the Komi Republic (Syktyvkar) on sod-podzolic soils with an average humus content of 2.8–3.4%. The objects of the study in the field experiments were zoned potato varieties: early-ripening Gloria variety and the middle-aged variety Nevsky. The following pectic polysaccharides served as stimulants of potato growth and development: heracleuman – pectin of Heracleum sosnowskyi Manden., lemnan – pectin duckweed Lemna minor L. and silenan – pectin of callus tissue of campion Silene vulgaris (M.) G. Processing of potatoes with aqueous solutions of pectic polysaccharides included pre-planting soaking of potato tubers in water and spraying potato plants in the phases of 3–5 leaves and tuber formation. For processing potatoes, working solutions were used, which were prepared from 100 times diluted 0.002% aqueous solutions of pectins. The consumption of the working solutions of pectins were 10 liters on 1 ton of tubers and 300 l/ha of planting potatoes. Tubers and potato plants treated with water instead of pectins were used as control samples. It is established that all tested pectins possess growth-stimulating activity and processing of potatoes with aqueous solutions of pectic polysaccharides increases the early and overall yield of this crop, as well as the content of dry matter, starch and vitamin C in potato tubers.

Full textAbstract:
Selotapak is one of the villages in the Trawas District area of Mojokerto Regency, East Java. This village is one of the sweet potato producing communities. At the time of harvest, the harvest reaches 40-50 tons per hectare. But often at the time of harvest, the price of sweet potatoes becomes very low. This price makes farmers unable to benefit, even many who lose. On the other hand, the storage period of sweet potatoes is also not long. The farmers must immediately sell their crops. Therefore another alternative is needed in marketing sweet potatoes so that the selling price can increase. One way to do this is by processing sweet potatoes into other products with longer shelf life and higher prices. In this activity, training in preparing sweet potatoes into several products, namely flour, noodles, brownies, roll ice cream, and yoghurt. This activity can be done through PKK empowermen and several youth organizations. Based on the training results, over 80% of the training participants feel the benefits of the training,. The participants can practice it independently in producing this sweet potato-based product. By making sweet potatoes into flour, the storage period extended. Sweet potato flour can be used to make other food products that become superior products in the village of Selotapak. For the sustainability of sweet potato processing, it is necessary to cooperate with all village communities in marketing their products. The role of the village government is essential in this regard, for example, by requiring presenting sweet potato products (at least one piece) as consumption in each village activity. For the next steps, supporting training is needed for the development of superior village products, for example training in making packaging and marketing.

Full textAbstract:
Acreage of white potato production in Pennsylvania has steadily declined in the past 20 years, from ≈25,000 acres in 1976 to 18,000 acres in 1996. This decline in acreage has occurred mainly with potatoes used for chips, with a much smaller acreage loss for tablestock potatoes. The most common tablestock varieties on the market are round white or long russet varieties, which have been around for 30 to 50 years. However, the 90's consumer is more perceptive and creative with food choices, such that color, texture, and taste have become important characteristics in choosing new food items. Specialty new potatoes represent a relatively unexplored market with excellent potential for sales expansion in the fresh market and tablestock industry. Today's consumers are demanding more variety with respect to virtually all produce commodities and potatoes are no exception. Consumers demand different size, color, and taste of fresh vegetables, including potatoes. New specialty potato varieties (Yukon Gold is an example) are currently in demand by restaurants and some retail markets, and it appears that relatively high returns are possible with these specialty potatoes. Twenty-nine red, buff, or blue-skinned and white-, yellow-, purple-, or red-fl eshed potato varieties were planted in a replicated study at the Hort Research Farm, Rock Springs, Pa., in 1996. Yield and quality characteristics of these varieties will be presented along with some consumer acceptance/evaluation data collected from a local supermarket.

Full textAbstract:
Overall potato consumption is positively associated with cardiovascular disease (CVD) risk factors, such as measures of adiposity. However, few studies have explicitly stated the preparation method of potatoes, which may impact these associations. We examined cross-sectional associations between self-reported dietary intake of boiled potatoes and levels of body mass index, waist circumference, blood pressure, and blood lipids among 43,683 participants in the HUNT Study, Norway in 2006–2008. All estimated associations were adjusted for possible imbalance in age, sex, physical activity, smoking, intake of other foods and alcohol between categories of boiled potato consumption. Overall, there were no large differences in mean levels of CVD risk factors between categories of boiled potato consumption. Compared to the reference group of individuals who consumed boiled potatoes less than once/week, those who reported eating boiled potatoes every day had slightly higher prevalence of high waist circumference (odds ratio [OR] 1.16, 95% confidence interval [CI] 1.05–1.29), high triglycerides levels (OR 1.20, 95% CI 1.07–1.34), and metabolic syndrome (OR 1.17, 95% CI 1.03–1.33). In summary, consumption of boiled potatoes showed weak and small associations with the CVD risk factors under study, but the cross-sectional design prevents us from drawing any firm conclusions.

Full textAbstract:
The potato has been a widely used vegetable crop in temperate countries for a long time. Its consumption and the area of its cultivation has increased significantly over the past decades in the tropics and subtropics as well. The main problems of potato producers in the tropics and subtropics are the unsatisfactory quality of seed potatoes, mainly derived from the informal seed supply system, and the insufficient availability and high cost of certified seed potatoes. The hope for improving this situation can be the application of soil-less technologies for minituber production under controlled conditions. This publication focuses on important advantages of the aeroponic system in the production of pre-basic seed potatoes in the tropics and subtropics. It also highlights some deficiencies that can be overcome with the involvement of several actors in the potato industry, including local universities and the private sector. It emphasizes that innovative aeroponic installations are an opportunity to increase the production of high-quality seed potatoes in the countries of the tropics and subtropics, which, in many cases, will result in less dependence on expensive imported seed potatoes, often from a different climate zone. The introduction of aeroponic installations conserves the shrinking natural soil and water resources and contributes to their protection.

Full textAbstract:
Potato has become one of the staple crops to improve food security in North Korea since the late 1990s. However, the potato yield has been stagnated around 11–12 t ha−1 for several decades, and a food shortage is still a primary issue in North Korea. Yield gap analyses were carried out using the SUBSTOR-potato model to quantify the potato yield gaps and explore the potential ways to close the yield gaps in two different cropping seasons in North Korea (early- and main-season potatoes). Yield gaps were estimated to be around 80% for both early- and main-season potatoes. Early-season potato yield was substantially determined by water or nitrogen supplies, depending on the year’s weather condition (i.e., with or without spring drought). Irrigation during the vegetative stage could effectively reduce the year-to-year variation in yield as well as the yield gap (+7.0 t ha−1, +66.1%). Meanwhile, additional nitrogen fertilizer in the early-season potatoes was less effective compared to that in the main-season potatoes. For the main-season potatoes, where precipitation was sufficient, the primary limiting factor of yield was nitrogen supply. Since heavy rainfall aggravated nitrogen leaching, additional nitrogen fertilizer is recommended as a top dressing rather than a basal dressing. Additional top dressing at 50 days after planting with the current amount of nitrogen fertilizer was expected to increase the main-season potato yield by 42.0 t ha−1 (+191.4%). This study highlights that the primary limiting factor of potato yield may differ between the cropping seasons. Therefore, our findings suggest that different agronomic strategies should be applied for different cropping seasons to improve potato production in North Korea, where agronomic resources are limited.

Full textAbstract:
Many types of spoilage and pathogenic microorganisms exist on fresh, minimally processed, and fully processed potato products. Potatoes are processed into many products including frozen, dried, ready-to-eat, and minimally processed. The microbiological quality of finished potato products is influenced by the natural microflora, processing, handling, and human contact. The natural microflora of potatoes are influenced by soil and airborne inocula, agricultural practices, harvesting methods, and storage conditions. The microflora of processed products are influenced by all of the factors and conditions affecting the natural microflora as well as the processes applied to the product. Increased consumer demand for new and existing potato products highlights the importance of ensuring their microbiological safety. This review considers the sources of microorganisms, microflora, foodborne disease pathogens, and outbreaks associated with, and selected microbiological research involving, potatoes and potato products.

Full textAbstract:
AbstractThe aim of this study was to evaluate changes in the sensory properties of the table potato in relation to the use of natural sprout inhibitors during long-term storage. The material for the study consisted in four varieties of potato of the medium early group. The research was carried out in the Plant Breeding and Acclimatization Institute – National Research Institute Branch in Jadwisin in 2014-2015. After harvest potatoes were stored from the end of October to April at 5°C, at the relative humidity of 90-95%, without application of natural sprout inhibitors (control) and using the natural sprout inhibitors (essential oils). After storage, the potatoes were boiled and sensory evaluation was carried out, which includes qualities such as: over-cooking of the surface, texture, mealiness, flesh texture, taste and smell. Study results showed that long-term storage of potatoes treated with natural sprout inhibitors – peppermint, caraway and clove essential oils is significant for the changes in overcooking the surface, structure of potatoes and mealiness of tubers after cooking. The taste and smell of potato tubers depended only on the variety.

Full textAbstract:
Despite frequently being described as a carbohydrate-laden, calorie-rich unimportant part of the human diet, potatoes (Solanum tuberosum L.) are one of the most nutritive vegetable food crops in the world and, in comparison to most other vegetables are richer in essential human nutrients. These include proteins, starch and fibre, major, secondary and trace minerals, vitamins, antioxidants and phytochemicals. Potatoes have an abundance of vitamin C and the mineral potassium (K) which are vital for health. Potassium reduces the risk of Blood Pressure (BP), cardiovascular diseases (CVDs), osteoporosis and strokes. Vitamin C helps reduce strokes and hypertension and prevents scurvy. The predominant form of carbohydrate (CHO) in the potato is starch. A small but significant part of this starch is resistant to digestion by enzymes in the stomach and small intestine, so it reaches the large intestine essentially intact. This resistant starch is considered to have similar physiological effects and health benefits as fibre. A medium size potato (148 g) contains 4 g protein and very small amount of fat or cholesterol. The fibre content of a potato with skin is equivalent to that of many whole grain breads and pastas. Potatoes contain rather large amount of the enzyme catalase, which converts hydrogen peroxide into oxygen and water and thus prevents cell injury. Potatoes contain phytochemicals such as lutein and zeaxanthin; which protect and preserve eyesight and may help reduce the risk of macular degeneration. It is not the high Glycemic Index (GI) in potatoes or in any other food, but the number of calories consumed from all foods that causes weight gain. Overall, potatoes are an underrated source of essential human nutrients. </P><P> Potatoes also contain toxic compounds, such as α-solanine and α-chaconine which are known to induce toxicity. These poisons cause gastrointestinal disturbances causing vomiting and diarrhea but severe poisoning may lead to paralysis, cardiac failure and comma. Green areas in potatoes containing chlorophyll are harmless but indicate that toxins may be present. According to the American Cancer Society, food born toxin such as acrylamide is formed when starchy foods such as potatoes and potato products are cooked at temperatures above 121C. However, deep frying at 170C is known to effectively lower the level of toxic compounds, while microwaving is only somewhat effective and freezedrying or dehydration has little effect. The highest levels of acrylamide are found in CHO-rich foods, such as potato chips and French fries, which had been cooked at high temperatures.

The study aimed at determining the effect of macro- and microelements contained in foliar fertilizers on potato productivity of tubers. The field experiment was conducted in 2015–2017 in Uhnin using the random blocks method. The first order factor were 2 cultivars of potatoes, the second order factor were 3 foliar fertilization technologies and standard object − without foliar spraying. Mineral fertilizers were constant. Foliar fertilizers were used in accordance with the recommendation of the producers. Foliar fertilizing has contributed to a significant increase in total and commercial yield. The cultivars determined the majority of potato's economic traits.

Full textAbstract:
Attributes of 25 Tasmanian sodosols were assessed using field and laboratory techniques to determine changes associated with 4 typical forms of agricultural management [long-term pasture, cropping with shallow tillage using discs and tines, cropping (including potatoes) with more rigorous and deeper tillage including deep ripping and powered implements, and cropping (including potatoes) where the potatoes were harvested when the soil was wet]. Soil organic carbon in the top 150 mm was 2.7% under long-term pasture compared with 1.8% in rigorously tilled cropping paddocks, and microbial biomass C values were 194 and 129 mg/kg, respectively. Readily oxidisable organic C concentrations were 1.8 mg/g and 1.3 mg/g, respectively. Infiltration rate was greater in paddocks with shallow tillage cropping than long-term pasture but was 43% less in paddocks which had grown potatoes and 70% less after a wet potato harvest. Dry aggregate-size showed no change under shallow tillage cropping compared with long-term pasture but decreased significantly in more rigorously tilled potato cropping paddocks. Aggregate stability in all cropped paddocks was nearly 50% less than in long-term pasture paddocks, with values in intensively tilled potato cropping paddocks approaching relatively low levels. Colwell extractable phosphorus (P) increased with all cropping, particularly after potatoes. Lower organic carbon and poorer physical properties were associated with paddocks which had grown potatoes, which adds weight to the view that cropping rotation and associated soil management practices are critical for sustainable management of Tasmanian sodosols. Farmers were surveyed about their views of the condition of their paddocks. They identified more healthy than unhealthy soil attributes under all management histories but reported more unhealthy soil attributes when potatoes were included in their rotation.
