The effects of application different amount cattle manure on some of quality and quantity characteristics such as plant height, stem diameter, head diameter, biological yield, seed yield, oil in seed and protein in seed on hybrids sunflower hybrids was investigated in 2008. This experiment was conducted at Agricultural and Natural Resource Research Station of Uremia. The experimental design was factorial based on randomized complete block design with three replications. Cattle manure levels with 0, 15, 30 and 45 t/ha as first factor and Iroflower, Alstare and Golshid varieties were as second factor. Results showed that application of cattle manure had significant effect on head diameter and biological yield at 1% and stem diameter at 5% probability levels. In addition, it was cleared that by increasing cattle manure application, stem diameter, head diameter, biological and seed yield were increased. The Golshid variety was superior in all traits except oil percentage. Interaction effect between cattle manure and variety was significant only in biological yield. There was positive significant correlation between seed yield and all the traits except oil percentage. regard to results of this experiment, it is expecting that by application of 30 t/ha cattle manure, an economical yield could be obtained from sunflower hybrids.
