Preliminary results of interaction between nitrogen fertilization and irrigation on the yield of winter wheat
Year: 2013
Type: article
Abstract: The aim of this study was to identify and quantify the effects of interaction of nitrogen fertilization at topdressing and irrigation on the yield of two winter wheat varieties in 2012/2013. In average for two treatments of irrigation and applied nitrogen, variety Zvezdana achieved significantly higher yield in comparison with Simonida. Comparing the yield obtained on control and irrigated treatments showed no significant differences. By analyzing the effects of increasing doses of nitrogen on the yield of winter wheat, it can be concluded that fertilization had the greatest impact on yield. However, the highest grain yield was obtained on the control treatment, and was significantly higher than yield achieved on all fertilized treatments. Unexpected results of an experiment could be explained by the specific, favourable climate conditions of the year, with abundant precipitation, relatively high temperatures and a high initial content of soil mineral nitrogen with subsequent high mineralization. Consequently, the expected effects of fertilization, especially irrigation on grain yield were not achieved.
