Abstract
The experiment was conducted on the land of Al-Mussaib Technical Institute - Al-Furat Al-Awsat Technical University in the winter season 2024-2025 to study the effect of spraying humic at three concentrations (2, 1, 0) L. dunum-1 and the effect of seaweed at three concentrations (150, 100, 0) mg. L-1. The experiment was conducted using a factorial experiment method that followed the RCBD design. The averages were compared using the LSD test at a 5% level of significance. A number of physical and chemical parameters, including bulk density, soil moisture, soil salinity, soil interaction, growth indicators, plant height, flag leaf area, number of ears, and total yield, were found to rise significantly when humic spraying was used. The treatment was given (humic spraying 2 liters. dunam-1) The highest averages in the aforementioned soil characteristics and crop growth indicators were obtained sequentially, while the treatment (spraying seaweed extracts (150 mg.L-1) The highest averages were in the aforementioned soil characteristics and yield growth indicators, respectively. The combination of the intervention (humic spraying 2 litres. dunam-1 and spraying seaweed extracts 150 mg. litre-1) also gave the highest averages above.
