A field experiment was conducted at Indira Gandhi Krishi Vishwavidyalaya, Raipur to aggregate the effect of different weed management treatments on Economics of rabi maize. Performance of the treatments in maize was observed under Randomized block design. The cost of cultivation was minimum under weedy check for 60 cm and 45 cm and it was maximum with the treatments hand weeding for 20 DAS and 40 DAS. The highest B:C ratio recorded with the treatment 45 cm + atrazine 1.0 kg ha^-1 PE fb topramezone 25.2 g ha^-1 (2.81) followed by the treatment 45 cm + atrazine 1.0 kg ha^-1 PE fb power weeder (25-30 DAS) (2.76), POST. The treatment 45 cm + atrazine 1.0 kg ha^-1 PE fb topramezone 25.2 g ha^-1, POST treatment generated highest gross (107504 Rs.) and net returns (69235 Rs.) when compared to other treatments. The lowest gross returns (Rs.), net returns (Rs.) and B:C ratio was recorded with the treatment weedy check for 45 cm and 60 cm. The treatments 45 cm + atrazine 1.0 kg ha^-1 PE fb power weeder (25-30 DAS) (T₅) was comparable with the treatment 45 cm + atrazine 1.0 kg ha^-1 PE fb topramezone 25.2 g ha^-1, POST (T₇) with respect to the returns.
