The field investigation was carried out in Sunflower during 2022-2023 at the Tamil Nadu Agricultural University in Coimbatore. To assess weed emergence in sunflower, 15 treatment combinations of tillage and weed management techniques were used in the experiment. Three replications of the split-plot design were used for the experiment. The data showed that, among the tillage techniques, the Mouldboard plough+ Cultivator+ Rotavator recorded lower total weed density and total dry weight with higher weed control efficiency, whereas with weed management techniques, hand weeding recorded lower weed density and dry weight with higher weed control efficiency which was on par with herbicide application. In the cultivator + rotavator in the unweeded treatment, higher total weed density and total weed dry weight with worse weed control effectiveness was noted. The relative density of the weed at 30, 60 and 90 DAS was recorded lower under MB plough fb cultivator fb rotavator. In the case of hand weeding and herbicide application, the relative weed density decreased after 30 DAS and increased during 90 DAS. Whereas in mulching, intercrop and unweeded check the relative density was increased after 30 DAS and decreased during 90 DAS.1260-1269
