The College of Education for Pure Sciences, Diyala University discussed a master dissertation on the allelopathic effect of sunflower parts on the germination and growth characteristics of salt-stressed wheat seeds and seedlings by the postgraduate student, Ms. Suha Mohammed Alwan.

The dissertation aimed at demonstrating the effect of aqueous extracts of different parts of the sunflower plant (roots, stems, and leaves) on improving the germination and growth characteristics of wheat seeds and seedlings (Triticum aestivum L.) under stress conditions.

The dissertation reviewed a significant decrease in most of the characteristics studied when irrigated with increasing concentrations of NaCl.

The dissertation also reviewed a significant decrease in the average values of the studied characteristics when irrigated with increasing concentrations of NaCl, furthermore, the addition of sunflower residues to the soil yielded the best results on the studied characteristics.
