Podzimní hnojení řepky ozimé dusíkem a sírou

The present beachelor thesis assessing the influence of autumnal nitrogen fertili-zation with sulfur on yield and oiliness of winter rapeseed. The issue was solved on small-plot field trial in year 2011-2012 in Žabčice near Brno. The attempt consisted of the following fertilization variants: 1. Control, 2. Amonium sulphate, 3. DASA (ammo-nium nitrate + ammonium sulphate, 4.MAGNISUL (Fertilizers contains nitrogen, sulfur and magnesium), 5. DASAMAG (ammonium nitrate + ammonium sulphate), 6. NPKS. Fertilizer application was carried out in the fall in 4 true leaves phase. Soil and fertilizer were each supplied by 40 kg N / ha. In the spring, there was an application of nitrogen in 3 doses (1 x DASA - 300 kg / ha, 2 x DAM 390-150 l / ha), NPKS doses (1 x DASA - 400 kg / ha, 1 x DAM 390-230 l / ha). The highest seed yield was reported in variant MAGNISUL. Due to the low yield, oil content in rape seed did not set. Effect of autumn fertilization did not show on the yield and quality parameters of winter rape seeds
