Podzimní aplikace stabilizovaného dusíkato-sirného hnojiva u řepky ozimé
Vrtěl, Petr
The aim of this bachelor thesis was to evaluate the efficiency of autumn fertilization technology with stabilized nitrogen-sulfur fertilizer (ENSIN) in oilseed rape. The experiment was established in the economical year 2014/2015 in the form of a small-plot field experiment on the fields of the School farm in Žabčice. Evaluation criterions were seed yield and oil contend of oilseed rape. The following variants of the ENSIN fertilizer application were included in the experiment: variant 1 in the autumn was not fertilized, variant 2 was in the autumn fertilized, variant 3 fertilized in the autumn later and variant 4 fertilized in autumn later and in spring at the beginning of elongation . The variants of fertilization were statistically inconclusive in seed yield and oil contend. Highest yield had variant 4.
Podzimní hnojení řepky ozimé dusíkem a sírou
Rábek, Michal
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.
