Abstract:
Energy utilization pattern is the vital characteristic for successful crop production. In the present paper energy analysis of rice under herbicide- based weed management practices has been studied at Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur (C.G.). Energy values were calculated by multiplying the amounts of inputs and outputs by their energy equivalents with the use of related conversion factors. The output/input ratio was determined by dividing the output value by the input. The highest grain yield (5.04 and 4.63 t/ha) and energy output (mean 143074.5 MJ/ha) were registered with the penoxsulam + cyhalofop-butyl 135 g/ha PoE during the year 2019 and 2020. It was also found that the application of post-emergence penoxsulam + cyhalofop-butyl 135 g/ha could be a very effective in terms of energy efficiency (12.82 MJ/ha/day) and energy productivity (0.43 g/MJ) among the herbicide- based weed management practices.
