Abstracts
In this paper, we are analyzing the yield and yield parameters of winter rape, fertilized using CULTAN system (Controlled Uptake Long Term Ammonium Nutrition) in comparison with top-dressing application of nitrogen fertilizers, which were studied on Haplic Luvisol over 5 years. No significant differences in seed yields between the two systems of fertilization were observed in 2008, 2009 and 2011. The effect of sulphur on a higher seed yield was proved in 2010 and 2012. The seed yield was higher by 11.4% in the treatments with sulphur amendment regardless of the system of fertilization in 2010. The seed yield was higher by 18.2 % in the CULTAN treatment with sulphur adittion in comparison to CULTAN treatment with no sulphur added in 2012. Nitrogen supply was ample in the first flowers open growth stage of winter rape in 2009, 2010 and 2012. The plant height was significantly lower after CULTAN method and as well as higher values of 1000 seed weight were recorded in comparison to top-dressing application in 2009. Nitrogen uptake by seed dry matter was the highest in the year 2009, which corresponds to the achieved seed yields this year.
