Soil organic carbon provides conditions for better plant growth by increasing soil quality by improving physical, chemical, and biological properties of the soil. Therefore, an experiment was conducted in a randomized complete block design (RCBD) with three replications at the Shavour Agricultural Research Station in Khuzestan Province to investigate the effect of different sources of organic matter on some soil properties and wheat yield. The main plots included cow manure, poultry manure, wheat straw, bagasse, and sugarcane filter cake, and the subplots included three fertilizer levels of 2.5, 5, and 10 tons per hectare. Also, one plot was considered as a control (without organic fertilizer) in each replication. The results showed that the best sources of organic fertilizer available in the province that have had a favorable result in increasing wheat yield and improving soil physical properties are filter cake, cow manure, and sugarcane bagasse fertilizers (with a yield of 4772, 4467, and 4452 kg/ha, respectively). Wheat straw also has the least effect on yield (4019 kg/ha) and plays a major role only in improving soil physical and chemical properties. It is worth noting that since no significant difference was observed between the fertilizer consumption amounts in the overall results, the consumption of 2.5 tons per hectare of each fertilizer source is more economical and is recommended. It also seems that the combined application of filter cake with sugarcane bagasse or cow or chicken manure with wheat straw and stubble, in a total amount of 2.5 tons per hectare, has a more favorable result in increasing wheat yield and improving soil physical properties.
