Abstract:
This study aimed to evaluate the effects of different types of vermicompost (sheep, cattle, and horse manure) and application rates (300, 600, 900, and 1200 kg/donum) on soil properties and cumin crop productivity in Al-Hasakah Governorate. Results demonstrated that horse-derived vermicompost was most effective in improving soil physical properties, significantly reducing bulk density while increasing porosity, thereby enhancing soil quality and facilitating water and air movement. Regarding chemical properties, sheep-derived vermicompost showed the greatest impact, improving pH and salinity levels while increasing essential nutrients (N, P, K), consequently boosting soil fertility and nutrient uptake. The 300 kg/donum application rate of sheep vermicompost achieved optimal economic returns, showing the most pronounced improvement in soil properties and cumin yield compared to other tested rates. Cattle vermicompost exhibited moderate improvements in both physical and chemical soil properties, though it proved less economically advantageous than sheep vermicompost.
