Abstract
A field experiment was carried out at Al-Hartiha Research Station of the college of agriculture, university of Basrah, during the winter season 2021-2022 to studying the effect of three levels of mineral fertilization NPK(0, Mineral fertilizer as recommended, 50% of recommended mineral fertilizer), and concentration extracts of licorice and m oringa leaf (0, spraying 50% of licorice extract, spraying 100% of licorice extract, spraying 50% of moringa leaves extract, spraying 100% of moringa leaves extract), on some growth characteristics of wheat. The experiment was applied according to the factorial method, using a randomized complete block design (R.C.B.D) with three replications. The results showed that the fertilizer recommendation 100% achieved the highest values of chlorophyll content of the flag leaf, the number of days to 50% flowering, plant height, flag leaf area, and the number of days to maturity (172.70 mg m-2, 102.33 day, 91.87cm, 26.67cm2 and 42.45 day), spraying with100% Licorice extract gave the highest content of chlorophyll, plant height, flag leaf area, and the number of days to 50% flowering and maturity (178.57 mg m-2, 90.22 cm, 26.33 cm and 42.78 day respectively). The interaction was significant in all characteristics, as the fertilizer recommendation spraying with 100% licorice extract achieved the highest chlorophyll content and flag leaf area, and it did not differ from the combination of 50% of the fertilizer recommendation and the concentration of 100% licorice extract in the chlorophyll content the area of the flag leaf and the number of days of to maturity.
