Abstract:
In the production area Marchfeld, this fertilization experiment with spring durum (Triticum durum) has been conducted as a master thesis at the Experimental Station in Gross Enzersdorf (Lower Austria). The aim was to dedect any benifits from deep banded fertilization (8 cm depth) in comparison to pre- and post-seed broadcasted fertilization. Furthermore three different types of fertilizer and amounts of 40 kg N / ha, 80 kg N / ha and 120 kg N / ha where studied with regard to of their effects on yield, selected agronomical parameters and on grain quality. All plots received a total of 120 kg N / ha as on the 40 kg N / ha plots in addition two more times 40 kg N / ha were spread and the 80 kg N / ha treatment got one more 40 kg N/ha application. A general recommendation is limited due to the lack of rainfall in 2012 and only an one year performance of the trial. But the data show a significantly higher yield of urea in banded fertilization. This could be explained by reducing the risk of gaseous ammonia losses from the soil. No significant differences are detected in NAC and ENTEC plots. The amount of fertilizer applied while sowing shows a significant effect on yield, grain moisture, and grain-straw ratio. Urea increases yield at a reduced quanitity of fertilizer while seeding. ENTEC however brings significantly higher yields at higher fertilizer rates while sowing. Soil coverage at EC 42-47 in urea and ENTEC treated variants is higher than in NAC plots. In summary the risk of nitrogen losses, particularly with urea, can be reduced by the ferilization in sub-soil. Furthermore the yield and the determinded agronomic parameters are majorly influenced by the quantity and type of fertilizer applied at seeding.
