A field experiment on weeding tools was conducted at farm of ICAR Research Complex for Eastern Region Patna during the Rabi season of 2015-16. Results revealed that treatment such as ‘khurpi’ was recorded the highest weed control efficiency (92.9%) followed by grubber (82.8%), spade (75.5%) and wheel hoe (72.2%). The highest human energy was also attained in case of ‘khurpi’ (567.62 MJ/ha) followed by spade (326.62 MJ/ha), grubber (212.62 MJ/ha) and wheel hoe (167.30 MJ/ha). The highest embodied energy was found in wheel hoe (93.18 MJ) followed by spade (45.05 MJ), grubber (20.17 MJ) and ‘khurpi’ (10.51 MJ). The field capacity of wheel hoe was found maximum (0.008 ha/hr) where as spade was minimum (0.0002 ha/hr). Hence, the wheel hoe was found to be the most efficient and cost effective weeding tool.
