The experiment was carried out at the Center for Biotechnology and Environment / University of Fallujah, during 2023-2024 season to study the effect of balance NPK concentrations on growth, yield and quality of some wheat cultivars. A split block arrangement according to RCBD was used with three replications. The study included two factors, the first was three varieties (Latifiyah, Al-Rasheed and Iraq) as a main plots, and the second factor was balance NPK fertilizer (20,20,20) with two concentrations (50 and 100 mg/L) in addition to control treatment (water only) as a sub plots. The results showed significant differences between varieties in most studied characteristic. Al-Rasheed cultivar gave highest averages of plant height (80.76cm), flag leaf area (38.66cm2), chlorophyll index (46.39 SPAD), spike length (12.90cm), spikes number (340.59m2), number of grains spike-1 (32.95 grain spike-1), 1000 grain weight (37.64g) and grain yield (4.127 t ha-1). Wheat plants that sprayed with NPK concentration 100mg/L gave highest averages of plant height (77.86cm), flag leaf area (40.34cm2), chlorophyll index (48.41 SPAD), spike length (12.50cm), spikes number (348.86m2), number of grains spike-1 (33.44 grain spike-1), 1000 grain weight (38.76g), grain yield (4.52 t ha-1) and protein percentage (12.75%). The effect of interaction for both factor was significant in most studied traits.
