The field experiments were made in irrigated sunflower to optimise the integrated nutrient and weed management practices for augmenting sunflower productivity, at Annamalai University Experimental Farm, Annamalai Nagar, Tamilnadu, India. The experiment was laid out in split plot design with three replications. The details of the treatment in mainplots are M1-Control, M2-RDF(40:20:20 kg NPK  ha-1) + FYM @ 12.5 t  ha-1, M3-RDF+ Vermicompost @ 5 t ha-1+seed treatment with Azospirillum (600 g ha-1)+ ZnSO4 @ 25 kg ha-1+ foliar spray of 1% KH2PO4 (twice at 25 and 55 DAS), M4- RDF+ FYM @ 12.5 t ha-1+seed treatment with Azospirillum (600 g ha-1)+ ZnSo4 @ 25 kg ha-1+ foliar spray of 1% KH2PO4 (twice at 25 and 55 DAS) M5- RDF+ Vermicompost @ 5 t ha-1+seed treatment with Azospirillum (600 g ha-1)+ ZnSo4 @ 25 kg ha-1 and M6- RDF+ FYM @ 12.5 t ha-1+seed treatment with Azospirillum (600 g ha-1)+ ZnSo4 @ 25 RDF+ FYM @ 12.5 t       ha-1+seed treatment with Azospirillum (600 g ha-1)+ ZnSO4 @ 25 kg ha-1and the subplots are S1- Unweeded control, S2- Pre emg. Oxyflourfen @ 0.1 kg ha-1 + HW at 30 DAS, S3- Pre sowing fluchloralin @ 1 kg ai ha-1 + HW at 30 DAS, S4- Pre emg. Pendimethalin @1 kg ai ha-1+ HW at 30 DAS and S5- HW twice at 15 and 30 DAS. The results of the study evidently proved that application of recommended NPK+  vermicompost +Azospirillum+ ZnSo4 + foliar spray of KH2PO4 along with fluchloralin + HW at 30 DAS (M3S5) as an agronomically efficient, eco-friendly and economically viable technology for improving sunflower yield and quality. This treatment (M3S5) combination registered lowest values for weed density, nutrient removal by weeds, weed biomass and maximum weed control index and maximum values for growth and yield attributes and yield, quality and nutrient uptake of sunflower in both the crops.
