This experiment had been conducted at directorate of agriculture research insulaymaniyah province for two winter growing seasons 2019/2020/ and 2020/ 2021. Theexperiment was on three bread wheat varieties ( Sulaymani2, Wafia and Rizgary)with threerates of seeding (30, 40, 50)kg/ donum. This experiment was carried out by using RandomizedComplete Block Design (RCBD) in Factorail experiment with three replications. The aim ofthis study was to indicate the best wheat seeding rate under sulaymaniyah environment. Theresult of combined analysis of variances show that the interaction between varieties and yearswas highly significances of all traits despite the seed yield and biological attributes. Effect ofyears doesn’t shown any significance of seed yield and number of seed per spikes, but theinteraction between seed rate and varieties (seed rate x varieties) and (seed rate x varieties xyears) doesn’t show any significance of variations despite of specific weight of seeds showsignificance in three interactions. Rizgary variety was show high significance comparing, byother two varieties. In the interaction between varieties, seed rate and years, Rizgary showhighest plant and higher biological yields by 88.73 cm, 13.437 ton/ hectare-1, 44.5gm weight of1000 kernel and 82.16 kg. hectoliter. On the other hand ( Sulaymani2 variety show higher seedyield by 3.873ton/ hectare comparing by other two varieties. Also, Wafia variety show highseed number per spikes by 59.66 seed and protein ratio by 17.87% comparing by ( Sulaymani2and Rizgary varieties. Regarding the seed rate in this study 50 kg /donum seed rate was shownhigh significance in all components yield, seed ingredients, hectoliter, yield and test weightcomparing by other two seed rates. The three interaction and two interactions of seed rates andvariety traits indicate the stability of variety in two years . The study result indicates that (Sulaymani2 and Rizgary varieties were shown significances of 50 kg/ donum than 40 kg and30 kg per donum.
