Potato is an important nutrient source in human nutrition. Potato tuber quality is affected by a cultivar, environmental conditions and agricultural practices. The study examined the effect of dose (0.2 dm3 ha–1 and 0.4 dm3 ha–1) and date of Tytanit® application (a single foliar application at the leaf development stage – BBCH 14–16 or at the tuber formation stage – BBCH 41–43, and a double foliar...
Background. New potatoes are imported to Poland mainly from the Mediterranean countries. In climate of the Mediterranean Basin potatoes can be grown twice a year. The different environment conditions during plant growth have effect on the tuber quality. Objective. The aim of the study was to assess the nutrition safety of new potatoes imported to Poland in the winter period from Mediterranean countries...
A condition for achieving a high potato tuber yield on an early harvest is to provide plants with good growth conditions. In modern horticulture, plant growth stimulants have been gaining increasing importance. This study examined the effect of dose (0.2 dm3 ha–1 or 0.4 dm3 ha–1) and date (leaf development stage – BBCH 14-16, tuber formation stage – BBCH 41-43, leaf development stage and tuber formation...
Background. Potatoes are an important component of the human diet. In addition to components which determine the nutrition and dietary values, potato tubers also contain anti-nutritional substances, inter alia radioactive elements. Natural and artifical radionuclides are released to the environment as a result of antropogenic activity, in a controlled or uncontrolled manner, and they are transferred...
Mineralsare the most important compounds for human nutrition that are sup-plied by vegetables. The content of mineral in vegetables depends on the species and the cultivar, but it is subject to changes under the influence of environmental conditions and agricultural factors. This study examined the effect of sowing date (5, 15 and 25 May) and plant spacing (1 × 0.6 m, 1 × 0.8 m and 1 × 1 m) on selected...
Potato has a relatively shallow root system and requires significant nutrient inputs to maintain tuber productivity and quality. Efficient application of the proper type and amount of fertilizer plays an important role in achieving profitable tuber yield with minimum nutrient loss to the environment. The aim of this study was to compare utilization of nutrients from NPKMgS-type fertilizer complex...
Background. Vegetables constitute a vital part of the human diet, being the main source of minerals, vitamins, dietary fibre and phytochemicals. They however, also contain nitrates and nitrites, which adversely affect human health. Objective. To determine nitrate and nitrite content in selected vegetables purchased at supermarket chains in Siedlce and to assess their impact on consumer health. Material...
The aim of the study was to compare the effect of multi- -nutrient complex fertilizers (HydroComplex, Nitrophoska Blue Special and Viking 13 from the nitrophoska group, and Polimag S from the amophoska group) and single-nutrient fertilizers on the growth and tuber yield of very early potato cultivars (‘Aster’, ‘Fresco’, ‘Gloria’). The field experiment was carried out on podzolic soil in mid-eastern...
Fertilization is one of the most important factors which can significantly affect potato tuber quality. The effect of multi-nutrient complex fertilizers (HydroComplex, Nitrophoska Blue Special and Viking 13 representing the nitrophoska group, and Polimag S from the amophoska group), and single-nutrient fertilizers (ammonium nitrate, single superphosphate and potassium sulphate) on tuber quality of...
