Abstract

This study was conducted at Erzurum in 2013 and 2014 to determine the effects of nitrogen fertilizer applied three different varieties oil type sunflower (Helianthus annus L.) at different developmental periods on quality and yield. Three sunflower types (Tarsan, L65400 and Imeria), three application times (stage of sowing, emergence and head formation) and four doses of nitrogen (0, 30, 60 and 90 kg ha-1) was set up in three repetitions at the arrangement of "Split Plot". Oil and protein content and grain and oil yields were investigated in the study. While the effect of N application on oil and protein contents of the experimental years was not significant, its the effect on grain and oil yield was significant. Nitrogen fertilizers applied at the time of sowing had more effect on the other characters than the fertilizer application at the time of flowering and plate formation. The effect of nitrogen doses on all the characters studied was significant. The 30 kg nitrogen application and the rate of protein in 90 kg nitrogen application per ha-1 were higher than other doses of grain and oil. Except for the oil content, there was a significant difference between protein content and varieties for grain and oil yield. As a result of this study, it could be concluded that 60 kg of nitrogen applied at the time of sowing, 90 kg ha-1 of nitrogen dose, early and late sunflower varieties (Imeria and Tarsan) at the time of harvesting to obtained high the grains and oil content.
