A field experiment was carried out at the Agricultural Scientific Research Center in Raqqa during the season 2020/2021, to study the effect of organic, and chemical fertilization and the interaction on some morphological and productive traits of certified varieties of durum (Triticum durum Desf) and bread (Trticum aestivum L.) wheat.  A split-plot design was used with three replications, where the first factor represented 4 fertilization treatments (organic, chemical, 50% organic + 50% chemical, 75% organic + 25% chemical), and the second factor 4 wheat varieties durum and bread (Sham 9, Buhouth 11, Sham 10, Buhouth 8).  Results showed that studied treatments gave early heading, except for the organic fertilization, which was delayed with the heading, and the Sham 10 variety was first with heading with chemical fertilization with an average of 107.7 days.  All treatments were superior in plant height except for the treatment of organic fertilization.  The variety Sham9 achieved superiority in plant height of 85 cm. The variety Sham 10 with fertilization treatment (75% organic + 25% chemical) recorded the highest spike length and 1000 grain weight with an average of 7.1 cm and 47.9 grams, respectively.  The chemical fertilization treatment achieved the highest grain yield with an average of 5.065 tons/ha, without significant differences from the fertilization treatment (50% organic and 50% chemical) with an average of 4.699 tons/ha.  The variety Bohouth 8, and chemical fertilization, achieved the highest grain yield ( 6.320 ton/ha).  The study concluded that the two wheat varieties  Buhouth 8 and Sham 10 were preferred in the study area and fertilized using half the rate of organic and chemical fertilization.
