| Abstract | ||
| Factorial experiment were conducted at the experimental farm of Field Crop Sciences, College of Agriculturel/ Abu-Ghraib/ University of Baghdad during the winter season of the years 2008-2009 and 2009-2010. The study aimed to investigate response of wheat cultivars to seeding rates its relationship with yield and its components. Randomized Complete Block Design (RCBD) was used with four replicates. In the first experiment, four cultivars of bread wheat (Al-Iraq, Al-Fatih, Abu-Ghraib-3 and IPA-99) were planted with five seeding rates (60, 80, 100, 120 and 140 kg.ha-1). Results revealed that cultivars were significantly different in both seasons The Iraq cultivars was superioty in plant height (92.892 and 87.55 cm), flag leaf area (46.783 and 29.411 cm2), 1000 grain weight (43.392 and 38.146 gm) and grain yield (6.36 and 5.852 tan.ha-1.) in both seasons, respectively. Meanwhile, the seeding rate 60 kg.ha-1 resulted in the highest average flag leaf area (43.489 and 32.180 cm2), 1000 grain weight (39.455 and 35.733 gm), and grain number.spike-1 (49.969 and 39.675 grain.spike-1) compared to other seed rates Entered all items in the start-up phase branching rates of seed All at one time after the possession of any compilation was thermally 327.342 (GDD) Growing Degree Days as an average of two seasons. but Differed in the average number of branches, while the same varieties entered the stage Maximum number of branches after the acquisition was a compilation of thermally 815.529GDD average of two seasons. | ||
