Abstract: Field experiment was conducted during kharif season of 2014 and 2015 at Main Agricultural Research Station, UAS, Dharwad to know the allelopathic effect of preceded summer sunflower on kharif mungbean (Vigna radiata) under varied sowing dates. Pooled data indicated that significantly higher seed yield of mungbean was obtained in kharif mungbean preceded by summer fallow land (CS₂-556 kg ha^-1) compared to kharif mungbean preceded by summer sunflower (CS₁-397 kg ha^-1). All the growth and yield parameters of mungbean were affected when it was preceded by summer sunflower which indicated the allelopathic effect of sunflower on mungbean.
