The effect of selected factors on the content of protein and nitrates in potato tubers

Original language description

The aim of study was to determine the effect of region, variety, year and ecological and conventional way of cultivation on the content of total protein and nitrates in the potato tubers in three years field trials. The effects of selected factors on nitrate and protein contents were similar, more significant for nitrates. Growing regions, varieties and years of cultivation caused statistically significant effects whereas the effect of ecological way of cultivation was less pronounced and showed a tendency without significance. Higher region showed lesser average nitrate (113.4 mg.kg-1) and protein content (4.27 % DM) in comparison with lower region (143.7 mg.kg-1 and 4.72 % DM). The highest nitrate content was found in Impala and Karin varieties (199.2 and 167.6 mg.kg-1); Karin variety was also rich in total proteins (4.86 % DM). Ecological way of cultivation has shown no significant difference on nitrate content (136.9 mg.kg-1) and protein content (4.41 %) as compared with convention
