“…The differences between organic and integrated production due to the distinct agricultural practices resulting in a variable mineral nutrition and application of chemical/artificial pesticides in organic farming, may modify quality, taste and the amounts of pesticide residues. Under organic farming a higher content of dry matter, mineral nutrients, amino acids, and chosen antioxidants as well as lower nitrate content in potato tuber were reported [11–12, 24–26, 36–37]. In the present study, under conditions of moderate stress as usual in the case of organic farming, the production of phenolic compounds, flavonoids and ascorbic acid was significantly higher than in the integrated production system.…”

The concentrations of the bioactive compounds in potato tubers are determined by both genetic potential and environmental factors. The purpose of the experiment was to determine the influence of organic and integrated production on the expression of the genetic potential with respect to the antioxidant properties of potato tubers and to evaluate its stability under different environmental conditions. This phenotyping was performed on seven new breeding lines (tetraploid clones) and three modern cultivars: Jelly, Satina and Tajfun. The results indicated that production system and location significantly influenced the antioxidant capacity measured by FRAP method. Organic farming and the location Chwałowice were characterized by higher values. Furthermore, anitioxidative capacity measured by FRAP method was correlated with chlorogenic acid content (r = 0.590**) and glutathione fractions, especially with the reduced form (GSH, r = 0.692**). Multidimensional comparative analysis (MCA) proved a better development of antioxidant properties of potato tubers in the organic cultivation system when compared with the integrated. Especially favorable were growing conditions at Boguchwała (organic) and worst at Młochów (integrated). From all investigated varieties, the best antioxidant properties were found in ‘Satina’ and ‘Jelly’. Clones TG-97-403 and 13-VIII-45 developed the weakest health promoting traits.

“…In our study, for potato, applying high nitrogen fertilization (600 kg ha -1 ) caused very high nitrate content (1080 mg kg -1 ). This result is consistent with those of Lin et al (2005) and Bártová et al (2013). For parsley, Petropoulos et al (2008) showed that increasing nitrogen fertilization from 75 to 300 kg ha -1 resulted in an increase of nitrate content in parsley leaves with respective values of 77 and 141 mg kg -1 .…”

“…Indeed, from the three tested varieties, it was found that 'Arinda' accumulated more nitrates than the 'Spunta' variety with respective values of 70.6 and 55.3 mg kg -1 . These results are confirmed by Bártová et al (2013) where significant genotypic variations between potato varieties were observed. Also, we demonstrated that the nitrate content changed between organically or conventionally farming system, for all the vegetable species tested.…”

This study reports the nitrate level of 22 vegetables species collected from 40 farms in several locations of an intensive agricultural area in two regions of Tunisia (Sousse and Monastir). Nitrate levels ranged between 57 and 2970 mg kg -1 . The highest and the lowest levels were found in turnip and tomato, respectively. Only five species (potato, field bean, cauliflower, pea and artichoke) had exceeded the norms established by the World Health Organization. Factors influencing nitrate accumulation in some vegetables were analyzed and discussed. It was observed that nitrate contents in vegetables varied depending on the type of vegetables, genetic factor, level of nitrogen fertilization and soil nitrogen content.

“…The difference in phenolic content in crops in EZ and in HA could be explained by environmental differences in field trials, long culture days at low temperatures (Reyes et al, 2004), by the use of organic fertilizers and cold environment (Hajslova et al, 2005) and cultivation under drought stress (Delgado et al, 2001). Information is still limited on the influence of organic and conventional farming on the content of phytonutrients; it has only been reported that organic farming has a high effect on potato tuber yield (Palmer et al, 2013) and the differences in protein content were not statistically significant (Bartova et al, 2013). Several researchers Hamouz et al, 2010;Lachman et al, 2009;Reddivari et al, 2007;Wegener et al, 2009) highlight the prevalence of genotypic variation in environmental conditions.…”

Potato is grown and consumed throughout the world for their particular calorific nutritional value and vitamin C, but it also contains phytochemicals (secondary metabolites) that have been studied and found to have positive effects in preventing degenerative diseases in human health, such as hypertensive activity, and also atherosclerosis, type 2 diabetes, liver fibrosis, Alzheimer's disease, macular degeneration and cancer. We aimed to identify and quantify phenolic compounds in potatoes grown on El Zuro (EZ) and Huayatan Alto (HA) in Santiago de Chuco, La Libertad, Peru. The field trials were carried out in EZ (altitude 3750 m.a.s.l.) and HA (altitude 3150 m.a.s.l.) employing organic and inorganic fertilization respectively. Extraction from the peel and flesh was obtained separately, with the following solution: 50% methanol, 50% deionized water and 0.5% acetic acid. The sample was injected into the system UPLC -MS / MS, using ESI ionization (Electrospray Ionization) and fifteen external reference standards. Thirteen metabolites were detected in the flesh and potato peel. The highest content of secondary metabolites (mg/100 g DW) were: Chlorogenic acid (476.82 ± 63.58), neochlorogenic acid (87.90 ± 19.42) caffeic acid (77.53 ± 14.49) and vanillin (11.52 ± 1.38). The PCA (Principal Components Analysis) scores show that the highest concentration of metabolites was found in the peel of both cultivars. We concluded that the native potato Huagalina contains the genes expressed in different biosynthetic pathways of the metabolites found in this study.
