A field experiment was conducted at the Agricultural Research Station of the College of Agriculture, Tikrit University, during the autumn growing season of 2024. The split-split-block design was used, including the use of diammonium phosphate (DAP) fertilizer at four phosphorus levels (0, 50, 100, and 150 kg/ha) (21% phosphorus), zeolite at three levels (0, 2.5, and 5 tons/ha), and organic matter at two levels (0 and 10 tons/ha). Sheep manure was added before planting of agriculture. The soil at the site contained 5% gypsum. The study aimed to evaluate the effect of adding zeolite, organic matter, and phosphorus on some characteristics of wheat plants. The use of zeolite, organic matter, and phosphorus, individually or in combination, resulted in a significant increase in all studied growth characteristics, such as dry weight after 30 and 60 days of planting, chlorophyll, plant length, and the percentage of P% in straw. The application of zeolite (5 tons/ha), organic matter (10 tons/ha), and phosphorus (150 kg/ha) resulted in the highest values for dry weight after 30 days of planting (62.48 g), dry weight after 60 days of planting (120.73 g), chlorophyll (59.70), plant length (103.66 cm), and the percentage of P% in straw (0.27 %) compared to the treatment of zeolite (0), organic matter (0), and phosphorus (0), which gave 22.87 g, 96.86 g,   38.82, 92.33 cm, and 0.07%, respectively.
