THE FUSARIUM ATTACK ON SOME WINTER WHEAT VARIETIES IN CORELATION WITH NITROGEN FERTILIZATION
Journal Title: Natural Resources and Sustainable Development - Year 2011, Vol 1, Issue 1
Abstract
In the lasts decades, the Fusarium head blight become the most damaged disease of wheat, especial during the rainy springtime. The year 2010 was one of these types, especial in western Romania. It was an opportunity for us to study this disease, in natural infection conditions. Our results stand out the superior resistance of some varieties (Josef, Kristina, Apache and Litera), appreciate by fervency, intensity and attack degree. By the correlation method, we determined that the varieties with great spike densities are more affected by the attack. Also, the attack parameters correlate in variants fertilized and unfertilized with nitrogen, demonstrating that, even the attack is greater in fertilized variant, the susceptible varieties have the same reaction with low nitrogen fertilization. Information confirmed in this experiment is that the quality of seeds (wet gluten, total proteins and sedimentation index) are depending of fusarium attack intensity.
