A two-factorial field experiment was performed in a randomized block design with three replications in 2010-11 in the Experimental Garden of the University of Warmia and Mazury in Olsztyn, to determine the effect of seedling planting time on the concentrations of mineral compounds in basil leaves. Plot area was 1.2 m2. The experimental factors were: (1) plants of sweet basil, purple (purpurascens) basil, and cinnamon basil, and (2) time of planting basil seedlings. The concentrations of macroelements (total nitrogen, phosphorus, potassium, magnesium, calcium, and sodium) and microelements (iron and copper) were determined in basil leaves. The content of total nitrogen, phosphorus, potassium, magnesium, calcium, and sodium in basil leaves depended on the cultivar. Cinnamon basil contained the highest concentrations of total nitrogen, phosphorus, magnesium, and calcium, whereas sweet basil had the highest content of potassium and sodium. The time of planting seedlings had a significant effect on the iron content of basil leaves, which was higher in plants that developed from seedlings planted on 19 May.

The objective of the investigations was to evaluate changes in concentrations of total protein (nitrogen x 6.25), phosphorus and potassium in tubers of two potato cultivars: Rywal and Saturna, as dependent on the application of herbicides (Afalon 50 WP, Azogard 50 WP, Sencor 70 WG, and Apyros 75 WG), after harvest and after 3 and 6 months of storage. Concentrations of total protein, phosphorus and potassium in potato tubers were strongly conditioned by genetic features of the cultivars. The tubers collected from the objects sprayed with the herbicides over the vegetation period contained by 3.7%, 8.1%, and by 3.5% more protein, phosphorus and potassium, respectively, than those nursed exclusively mechanically. The corresponding values in the latter case reached respectively (means for the objects with the use of herbicides) 24.4 g kg-1, 660.5 mg kg-1 and 5351.3 mg kg-1. After 3 and 6 months of storage at 8°C, the content of nitrogen was significantly lower. Similarly, tubers stored at 4oC contained significantly less nitrogen, but not earlier than after 6 months. In contrast, concentrations of phosphorus and potassium did not change significantly over the storage of tubers in chambers with the lower temperature (4°C).

Celem badań było określenie zmian zawartości białka ogólnego (azot x 6,25), fosforu i potasu w bulwach ziemniaka odmian Rywal i Saturna w zależności od zastosowanych herbicydów (Afalon 50 WP, Azogard 50 WP, Sencor 70 WG, Apyros 75 WG), po zbiorze i po3 i 6 miesi¹cach przechowywania. Zawartość białka ogólnego, fosforu i potasu w bulwach ziemniaka różnicowały istotnie uwarunkowania genetyczne odmian. Bulwy zebrane z obiektów opryskiwanych herbicydami w okresie wegetacji roślin zawierały o 3,7% więcej białka, o 8,1% fosforu, o 3,5% potasu niż bulwy roślin pielęgnowanych wyłącznie mechanicznie, dla których wartości te wynosiły odpowiednio (średnio dla obiektów opryskiwanych herbicydami): 24,4 g kg-1, 660,5 mg kg-1 i 5351,3 mg kg-1. Po 3 i po 6 miesi¹cach przechowywania w temp. 8°C zawartość azotu istotnie się zmniejszała. Również w bulwach przechowywanych w temp. 4°C poziom azotu istotnie się zmniejszył, lecz dopiero po 6 miesiącach. Natomiast zawartość fosforu i potasu nie zmieniała się istotnie podczas przechowywania w bulwach składowanych w komorach o niższej temperaturze (4°C).

The experiment was performed on 24 ewes divided into 4 groups. Experimental sheep were injected parenterally either with a sodium selenite and Emulsigen mixture or sodium selenite or Emulsigen. The injection of sodium selenite and Emusigen mixture, and Emulsigen alone substantially increased serum copper and magnesium concentrations. Moreover, a marked decrease in creatine kinase activity was found in all experimental groups as compared to that in the controls. No significant alterations in iron, zinc, calcium, and phosphorus concentrations and the enzyme's activities were noted.
