الملخص

This study was conducted in the gardens of the scientific departments - College of Education for Girls - Tikrit University for the agricultural season 2022-2023 to study the effect of two varieties of bread wheat (Triticum aestivum L. (Abaa 99, Adana 99) and different concentrations of humic acid [0, 0.5 and 1] ml) and irrigation periods. Every (25, 35 and 45) days in terms of growth characteristics and gluten percentage. Statistical analysis was conducted at the level of (P≤0.05) and the results appeared as follows. The triple interaction between the lowest variety treated with acid at a concentration of 1 ml and watering every 25 days was superior to the rest of the interactions with the highest values for the characteristics of plant height, number of shoots, relative water, and flag leaf area, which were 104.72% and 40. 72%, 37.63%, and 45.37%. The same interaction also outperformed the qualitative characteristics, which are the percentage of chlorophyll and the percentage of gluten given, and the percentage of gluten is 100% and 10.40%, respectively.
