A field experiment was conducted at Advanced Centre for Rainfed Agriculture, Rakh Dhiansar of Sher-e- Kashmir University of Agricultural Sciences and Technology of Jammu during the Kharif seasons of 2016-2017 and 2017-2018 to identify the best herbicide option for weed management in maize (Zea mays L.) The experimental field was highly infested with broad-leaved weeds: Amaranthus viridis and Solanum nigrum; grasses: Echinochloa colona, Digitaria sanguinalis, Acrachne racemosa, Eragrostis tenella, Eleusine aegyptium and sedges: Cyperus rotundus and Cyperus iria. The tank mix application of tembotrione 100 g/ha + atrazine 750 g/ha at 15-20 days after seeding (DAS) reduced the total weed density, biomass and nutrient uptake by weeds and increased the maize grain, stover yields and nutrient uptake by maize crop. It was at par with post-emergence application (PoE) of tank mixed tembotrione 100 g/ha + atrazine 500 g/ha 15-20 DAS; tembotrione 100 g/ha + halosulfuron 67.5 g/ha PoE 15-20 DAS; tembotrione 100 g/ha + halosulfuron 52.5g/ha PoE at 15 DAS and atrazine 1000 g/ha 0-3 DAS followed by (fb) tembotrione 100 g/ha15-20 DAS during both the years. Highest B: C ratio (3.11) was obtained with tembotrione 100 g/ha + atrazine 500 g/ha PoE at 15-20 DAS followed by the treatment of tembotrione 100 g/ha + atrazine 750 g/ha PoE at 15-20 DAS.
