Treść
Tubers for laboratory analyses were obtained in a field experiment conducted at the Zawady Experimental Farm owned by the Siedlce University of Natural Sciences and Humanities in 2008-2010. The experiment was a two-factor splitplot arrangement with three replicates. The following factors were examined: three cultivars: Cekin, Satina, Tajfun, and four weed control methods based on an application of herbicides or their mixtures: Command 480 EC 0.2 dm3·ha-1, Dispersive Afalon 450 SC 1.0 dm3·ha-1, Stomp 400 SC 3.5 dm3·ha-1 and no herbicide control. The aim of the study was to determine the effect of cultivars and herbicides mixtures on edible potato tuber contents of magnesium and potassium. Analysis demonstrated that genetic characteristics of the cultivars significantly affected magnesium content. The highest amount of magnesium was accumulated by Tajfun, on average 1.832 g kg-1, and the lowest by Cekin, on average 1.601 g kg-1. Also, variance analysis demonstrated a significant effect of weed control methods on magnesium content in potato tubers. Results of the study revealed that Tajfun and Cekin had, respectively, the highest and lowest potassium concentrations, on average 20.62 and 16.41 g kg-1. The herbicides and their mixtures applied in the experiment were found to significantly affect potato tuber dry matter content of potassium. A combination of mechanical and chemical weed control contributed to a decline in potassium content from 0.740 to 1.270 g kg-1, on average. Statistical analysis demonstrated that edible potato tuber content of potassium was significantly influenced by meteorological conditions in the study years.
