Vliv hnojení močovinou a UreaStabil na výnos a kvalitu brambor

The aim of my diploma thesis was to evaluate the effect of different doses of urea and UreaStabil fertilization on yield, tuber size and quality of potato tubers. A field experiment was carried out at the research station Valečov (Valkom Ltd.), the branch of the Potato Research Institute in Havlíčkův Brod during the years 2013 and 2014. Seven variants of fertilization were monitored in four repetitions of various doses of nitrogen fertilizer application as urea and UreaStabil and were compared to the unfertilized check variant. Two potato varieties, each with different lenght of the growing season, an early Karin and mid-early Red Anna, were used for comparison.
