For greater profitability, they must trade off against one another. To reduce the dependence on non-renewable resources, agricultural energy efficiency needs to be increased. Additionally, weed control is crucial to sustainability. In order to evaluate the energy balance, major energy indicators and profitability of maize under various weed control strategies, the current study was carried out. Therefore, a field experiment was carried out at farmers’ field in Kurmalur village of Perambalur District, Tamil Nadu, India during Kharif season of 2021 in order to evaluate different weed management practices on production and energy analysis of maize. The field experiment was laid out with ten treatments with three replications. The treatments consist of control, hand weeding on 15 and 30 DAS, pre-emergence application of atrazine, post emergence application of tembotrine, 2,4-D, halosulfuron methyl, Tembotrine, Mesotrione + Atrazine. Pre emergence application of Atrazine 1 kg/ha on 3 DAS fb Post emergence application of Tembotrine 105 g/ha on 20 DAS recorded the highest grain (4469 kg/ha) and straw yield (5708 kg/ha) with Net energy (156860 MJ/ha) and Energy Use Efficiency (14.55).
