Energy utilization pattern is the vital characteristic for successful crop production. In the present paper energy analysis of berseem (Trifolium alexandrinum L.) under different weed management practices has been studied at the Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur (C.G.). Significantly the highest total dry fodder yield (6.51 and 6.01 t/ha) was registered with the application of oxyfluorfen 0.25 kg/ha as PE over rest of the treatments during the year 2018-19 and 2019-20. It was also found that the PE application of oxyfluorfen 0.25 kg/ha could be a very effective in terms of energy output (mean 112680 MJ) and energy efficiency (8.46 MJ/ha/day) and energy productivity (0.47 kg/MJ) among the different weed management practices.
