Abstract:

The aim of this research was to determine the effect of the amount of nitrogen fertilizer and number of irrigations on the YB disorder of wheat cultivar Tarachi, as well as its relationship with protein content, and the agronomic characteristics. The experiment was conducted in northwestern Mexico, during the fall-winter season, 2009-2010. Three levels of nitrogen (75, 150 or 250 kg ha-1) and three levels of irrigation (3, 4 or 5 irrigations) were studied. Increasing the nitrogen rate decreased the YB content, the thousand kernel weight and hectoliter weight; and increased the protein content and the number of grains per spike. The number of irrigations did not affect the number of grains per spike. However, increasing the number of irrigations increased the YB content, the thousand kernel weight and hectoliter weight; on the other hand, the protein content decreased. A negative correlation between protein content and percentage of YB was presented. It was concluded that the presence of the disorder YB in bread wheat, Tarachi, is due to a low nitrogen rate in the soil and an increase in number of irrigations.
