Opis:: Our objective was to determine the content of macro- and micronutrients, toxic heavy metals as well as total phenols in 10 broccoli (Brassica oleracea var. italica) cultivars. The experiment was designed at the Poznań University of Life Sciences, Poland, and completed during two plant growing seasons. Broccoli seedlings were planted in a field in early July and the plants were harvested between September and October. The content of general forms of nitrogen was measured by distillation with the Kjeldahl method. The content of potassium, calcium and sodium was assessed by flame photometry, and the content of magnesium, cadmium, lead, nickel, copper, zinc, manganese and iron was determined by flame atomic absorption spectroscopy (FAAS). The content of heavy metals, macronutrients and sodium in the broccoli heads depended on a cultivar. Having analyzed the levels of macronutrients in ten broccoli cultivars, it was concluded that cv. Agassi and Tradition had the highest content of nitrogen and phosphorus. A very high amount of phosphorus was also found in cv. Beaumont. The highest concentrations of calcium and potassium were found in cv. Monte Carlo. The cultivars Agassi, Beaumont, Tiburon and Tradition were characterized by the highest content of magnesium. The highest content of sodium occurred in the cultivars Beaumont and Monopoly. With respect to micronutrients, the highest content of iron, copper, zinc and manganese was revealed in cv. Agassi. The highest content of nickel was determined in the cultivars Beaumont and Monte Carlo. In addition, the cultivar Monte Carlo was characterized by the highest content of lead, and Beaumont had the highest content of cadmium. However, the maximum permissible levels of cadmium and lead were not exceeded in the heads of the ten broccoli cultivars. In both years of the study, the highest content of phenols was found in cv. Steel and the lowest one appeared in cv. Agassi.

Opis:: The study was based on a three-year field experiment conducted on degraded black soil, classified as class IIIb soil in the Polish soil valuation system, with neutral pH, high content of phosphorus and potassium, average content of magnesium, and low content of sulphur. The two-factor experiment was carried out in northern Poland (52°73′ N; 18°88′ E), in a split-block design with four replications. The preceding crop each year was sugar beet. The aim of the study was to evaluate the effect of varied levels of nitrogen (first factor – 0, 60, 120 and 180 kg ha-1) and sulphur (second factor – 0, 20 and 60 kg ha-1) applied to the soil and onto the leaves on the content and ratio of these elements in the seeds of the Star cultivar of spring rapeseed. Little variation was noted between growing seasons in the content of nitrogen and sulphur and in their proportions in the seeds. Application of nitrogen alone (without sulphur) and combined application of nitrogen with sulphur caused an increase in the nitrogen content in the seeds and in the N:S ratio. The sulphur content in the seeds of the plants fertilized with nitrogen and sulphur together was significantly higher than in the seeds of the plants fertilized with nitrogen alone and lower than in the plants fertilized with sulphur alone. The highest N:S ratios were obtained in the seeds of plants fertilized with nitrogen alone, and the lowest – following the application of sulphur alone. Application of nitrogen or nitrogen and sulphur caused an increase in the N:S ratio towards optimal values for fodder crops. The method of sulphur application did not significantly affect its content in the rapeseeds or the N:S ratio.

Opis:: Red head cabbage comes in many varieties, which differ from one another in the length of vegetative period, yield quality and general biological value. The aim of our study has been to determine the content of anthocyanins in extracts from three different cultivars of red head cabbage (cv. Koda, Haco POL and Kissendrup SWE) and to examine their antioxidative activity. It was found that the content of anthocyanins in extracts from red head cabbage was significantly varied, depending on a cultivar. Extracts from cv. Kissendrup SWE contained significantly more anthocyanins, whereas those obtained from cv. Koda had the smallest content of those compounds. Anthocyanins extracted from cv. Haco POL red cabbage demonstrated the highest antioxidative capacity. Weak correlation was shown between the content of anthocyanins and their antioxidative capacity (R2 from 0.278 to 0.297).
Kapusta głowiasta czerwona ma wiele odmian, które różnią się długością okresu wegetacji, jakością plonu i ogólną wartością biologiczną. Celem pracy było oznaczenie zawartości związków antocyjanowych w ekstraktach trzech odmian kapusty głowiastej czerwonej (Koda, Haco POL, Kissendrup SWE) i zbadanie ich aktywności antyoksydacyjnej. Stwierdzono, że zawartość antocyjanów w ekstraktach z kapusty głowiastej czerwonej istotnie zależała od odmiany kapusty. Ekstrakty z kapusty odmiany Kissendrup SWE zawierały istotnie najwięcej antocyjanów, a najmniej ekstrakty z kapusty odmiany Koda. Antocyjany wyodrębnione z kapusty odmiany Haco POL wykazywały największą aktywność przeciwutleniającą. Wykazano słabą korelację między zawartością związków antocyjanowych a ich aktywnością antyoksydacyjną (R2 od 0,278 do 0,297).

Opis:: The experiments on celery, curly kale and lettuce reported in this paper were carried out in a greenhouse, with plants grown in 2 dm3 pots filled with peat substrate. The trials were established in a completely randomized design. The aim was to determine the effect of increasing nitrogen doses (0.3, 0.6, 0.9, 1.2 g N dm-3 of substrate) on N-tot., NO3-N, concentrations of P, K, Ca, Mg, Fe, Zn, Mn and Cu as well as ratios between these elements in three vegetable species such as curly kale, lettuce, and celery, distinguished by different degrees of sensitivity to salinity. An increase in the content of total nitrogen and NO3-N in lettuce, curly kale and celery appeared to be parallel to the increasing doses of nitrogen, while the average total nitrogen content was similar in all the tested species, and the content of N-NO3 in kale was about five-fold lower than in lettuce and celery. The level of nitrogen fertilization influenced the content of potassium and magnesium in lettuce as well as the content of phosphorus, potassium, calcium and magnesium in celery. The nitrogen doses significantly differentiated proportions between the nutrients in plants, mostly the K:Mg and Zn:Cu ratios. The increasing doses of nitrogen modified the content of microelements and proportions between various components in the tested plant species.

Opis:: Brassica oilseed crops have very high sulfur requirements. The progressive decrease in the sulfur content of soil, the growing share of cruciferous vegetables in agricultural ecosystems and a significant drop in annual wet and dry deposition of sulfur have prompted a growing body of research into sulfur as a valuable fertilizer ingredient. The aim of this study was to determine the effect of sulfur fertilizers applied to soil on nitrogen, phosphorus, potassium, calcium, magnesium and sulfur concentrations in the root residues, straw and oil cake of winter and spring rapeseed. The experimental material was collected from a field experiment conducted in 2005-2008 at the Agricultural Experiment Station in Bałcyny (Poland). The highest concentrations of nitrogen, phosphorus, magnesium and sulfur were noted in the oil cake of both winter and spring rapeseed. Potassium levels were highest in the root residues of winter and spring rapeseed. Winter rapeseed accumulated the highest amounts of calcium in roots, and spring rapeseed – in straw. Sulfur fertilizers applied to soil decreased nitrogen concentrations and increased calcium and sulfur levels in the roots of both spring and winter rapeseed, whereas phosphorus concentrations increased only in the roots of winter rapeseed. Sulfur fertilization led to a drop in the potassium content of winter rapeseed roots (by 0.7 g kg-1 DM) and an increase in potassium levels in spring rapeseed roots (by 1.2 g kg-1 DM). The application of sulfur fertilizers significantly increased potassium and sulfur concentrations in the straw of both spring and winter rapeseed (by 1.3-1.7 and 0.5-0.6 g kg-1 DM, respectively). The application of sulfur fertilizers at optimal doses for winter rapeseed significantly increased the calcium content of straw (by 1.3 g kg-1 DM), but did not lead to differences in nitrogen levels. Sulfur fertilization significantly reduced nitrogen (by 0.7 g kg-1 DM) and calcium (by 0.6 g kg-1 DM) concentrations of spring rapeseed straw. The content of all the analyzed macronutrients increased significantly in spring rapeseed oil cake in response to sulfur fertilization. Sulfur also increased the concentrations of the evaluated macronutrients, excluding nitrogen and phosphorus, in winter rapeseed oil cake.

Opis:: The aim of the study was to determine how soil contamination with petrol and diesel oil affected content of some macroelements in spring oilseed rape (Brassica napus var. oleifera) and oat (Avena sativa L.) and to determine whether application of compost, bentonite or calcium oxide could reduce the impact of petroleum-derived products on the properties of the plants. The soil formed from sandy loam was polluted with the following amounts of petrol and diesel oil: 2.5, 5.0 and 10 cm3⋅kg-1 of soil. The results of the tests showed that contamination of soil with diesel oil at the amount between 2.5 and 10 cm3⋅kg-1 of soil disturbed the plants’ chemical composition. Irrespective of the application of compost, bentonite or calcium oxide, the highest doses of petrol and especially diesel oil decreased the content of most macroelements in spring oilseed rape and, to a smaller degree, in oat. Enrichment of soil with compost, bentonite or calcium oxide modified the content of macroelements in plants, mainly that of sodium under the effect of bentonite. Significant correlations, mainly between the content of some macroelements in spring oilseed rape and oats versus plant yield and content of other elements in plants, as well as some properties of soil were observed.
Celem badań było określenie, w jaki sposób zanieczyszczenie gleby benzyną i olejem napędowym wpływa na zawartość niektórych makroskładników w rzepaku jarym (Brassica napus var. oleifera) i owsie (Avena sativa L.) oraz czy stosowanie kompostu, bentonitu i tlenku wapnia mogłoby zmniejszyć oddziaływanie substancji ropopochodnych na badane cechy roślin. Doświadczenia przeprowadzono na glebie wytworzonej z piasku gliniastego zanieczyszczonej rosnącymi dawkami benzyny i oleju napędowego: 2,5, 5,0 i 10 cm3⋅kg-1 gleby. W wyniku badań wykazano, że zanieczyszczenie gleby olejem napędowym w dawkach od 2,5 do 10 cm3⋅kg-1 gleby modyfikuje skład chemiczny roślin. Najwyższe dawki benzyny i oleju napędowego, niezależnie od aplikacji kompostu, bentonitu i tlenku wapnia, zmniejszały zawartość większości makroskładników w rzepaku jarym, i w mniejszym stopniu w owsie. Wzbogacenie gleby w kompost, bentonit i tlenek wapnia modyfikowało zawartość makroskładników w roślinach, głównie sodu, po zastosowaniu bentonitu. Istotne korelacje stwierdzono głównie między zawartością niektórych makroskładników w rzepaku jarym i owsie oraz plonem roślin i zawartością innych składników w roślinach, a także niektórymi właściwościami gleby.
