Greenhouse studies were conducted to evaluate the allelopathic effects of different parts of sunflower biomass (stem, leaf, inflorescence and root) on winter wheat. The influence of different sunflower biomass doses, i.e. control, normal (normal biomass in field crop), normal+25% and normal+50%, was also studied. Among the different parts of sunflower, stems showed the highest inhibitory effect on the growth and yield of wheat, followed by the roots, leaves and inflorescences. Increasing doses of sunflower biomass resulted in significant reductions in the seedling growth and yield of wheat.
