“…Valfi was 2.46 to 3.18-fold higher than in cultivars with yellowcolored flesh. Kröner et al (2012) and Brazinskiene et al (2014) did notobserve significant correlations between the phenolic acid content of potato tubers and the spread of P. infestans. According to the cited authors, the incidence of disease is more likely to be influenced by the production system than the phenolic acid content of tubers.…”

In this study, the influence of potato cultivars Irga, Satina, Valfi, Blaue St. Galler and Highland Burgundy Red (HB Red), growth regulators: Bio-Algeen S-90, Kelpak SL and Trifender WP, and the biostimulator Asahi SL on the health status of potato plants and tuber yield was investigated. The severity of late blight and early blight was estimated during the growing season. After harvest, potato tuber yield was determined according to size fractions. The applied treatments significantly reduced the severity of late blight in cv. Irga (Kelpak SL), Valfi (Bio-Algeen S-90, Kelpak SL, Trifender WP) and Blaue St. Galler (Trifender WP) in 2013. In 2015, the symptoms of early blight were significantly reduced in cv. Irga after the application of all tested bioregulators. HB Red was characterized by the best health status among the evaluated cultivars. Kelpak SL and BioAlgeen S-90 increased the tuber yield of cvs. Irga and HB Red, respectively, in 2013, and Trifender WP increased the tuber yield of cv. Satina in 2014. In the first year of the study, the applied growth regulators and biostimulator significantly increased the percentage of medium-sized tubers of cv. Blaue St. Galler, and Bio-Algeen S-90 increased the percentage of medium-sized tubers of cv. HB Red.

“…Lysine, the most abundant free amino acid in potato, was often found significantly higher in organic tubers [10,13]. Protein profiling also changes, with organic tuber proteome enriched in stress-related proteins [14], even though other authors, such as Brazinskene et al [15], are not in agreement with these findings. As reported by Brandt et al [16], the plants managed by organic practices have necessarily to cope more frequently with pathogens, and accordingly accumulate more defense-related compounds (such as phenylpropanoids [9,10,12,17]) than conventionally produced tubers.…”

Organic farming practices are commonly thought to reduce the environmental impact of agriculture and to preserve the naturalness of the products. Herein, we report the effect of crop management practices on nutritional and toxicological value of potato tubers. Comparative studies are often controversial and the results are dependent on genotype and methodological approach. Targeted analysis and "omics" strategies are discussed, pointing at the nutritional aspects and the corresponding biological and molecular processes involved. Organic farming supporters still do not accept the use of genetic modification to produce new varieties suited for organic agriculture and crop improvement by genetic engineering still sparks hot debate among various scientific and social factions whose major concern is the possible existence of unintended effects both on human and world health. In this context, the advent of "new plant breeding techniques" has reignited the discussion on genetic engineering and on the compatibility of the new technologies with an eco-friendly agriculture. Could cisgenic and genome-edited potatoes be new good options for organic agriculture? We discuss how these approaches can be used to address food security challenges and to overcome specific problems based on the biological characteristics of potato tubers, producing new varieties that can improve farmers' profit with a lower impact on public opinion. However, political, ethical, and social fears will probably persist much longer, mainly in Italy, historically a fiercely anti-GM country with a European leadership in organic food production and export.

“…The Brazilian production of potato, Solanum tuberosum, is one of the largest in the world (Amado et al, 2014, Brazinskiene et al, 2014 with an area of about 130,000 ha and a production of three million tons (FAO, 2013). This plant has a relatively shallow root system (Neumann et al, 2012) requiring large inputs of nutrients, especially nitrogen, to maintain productivity and tuber quality (Tein et al, 2014).…”

“…Additionally, the total dry matter of potato accumulated by photosynthesis is utilized in different parts of the plant according to its development stage (Singh et al, 2008). However, each variety requires proper management of nitrogen fertilization (Brazinskiene et al, 2014), which makes it necessary to use correct doses of this nutrient for potato (Zebarth et al, 2009). The objective of this study was to evaluate the accumulation of dry matter, nitrogen and the productivity of potato with different quantities of sunn hemp, Crotalaria juncea L as nitrogen source.…”

Growth patterns and distribution of dry matter in different parts of potato plants (Solanum tuberosum, Solanaceae) with green manure can be positively influenced by the use of green manure. The aim was to evaluate the dry matter accumulation and productivity of potato with varying quantities of sunn hemp, Crotalaria juncea (Fabaceae) as a nitrogen source. The experiment used three different amounts of sunn hemp, equivalent to 100, 200 and 400 Kg ha -1 nitrogen (N), the recommended mineral N dose (250 Kg ha -1 ), and a treatment with zero N. Sampling was carried out at 35, 50, 65 and 80 days after planting, representing the subplots. The treatments were arranged in a randomized block design with split plot, the plot were enlarged fertilization and the small plot sampling dates. Four replications were used. Dry matter accumulation in the shoots of potato was greater with sunn hemp than with mineral nitrogen. The accumulation of dry matter in tubers and in the whole plant increased over time at higher rates of sunn hemp than with mineral fertilizer. Commercial and total potato productivity increased with sunn hemp quantity. Green manure at higher rates (400 and 200 Kg ha -1 ) increased the accumulation of dry matter in potato aboveground parts and in tubers. The commercial productivity of potato was 24% greater with green manure than with mineral fertilizers, indicating the potential of sunn hemp to provide adequate quantities of nitrogen for the growth and development of this crop.Key words: Crotalaria juncea, harvest index, nitrogen, Solanum tuberosum.
