Weed management is an ever-present challenge to crop production. Presence of weeds in general reduces crop yield by 31.5 per cent (22.7 % in Rabi season and 36.5 per cent in Kharif and summer season). Yield losses due to weeds were about 65 per cent depending on the crop, degree of weed infestation, weed species and management practices. Presently available weeder mostly run by tractor or power tiller, these are large in size, cannot work for low inter row spaced crops.To over come these problems, portable knapsack power weeder was developed for low inter row spaced crops with width of cut was 25 cm. The main working components of power weeder were flexible drive shaft, worm gear box, rotor shaft, flanges and blades. The” L” type blade was selected having length, width and thickness of 130 mm, 30 mm and 5 mm, respectively, operating with a rotor shaft of 20 mm in diameter. Maize and chilli was tested with number of blades per flange (2, 4 and 6).Keywords

India is a vast country having agriculture sector as the backbone of its economy. A weed is essentially any plant which grows where it is unwanted or not required. A weed can be thought of as any plant growing in the wrong place at the wrong time and doing more harm to the farmer income. Several weeders are available which run by tractor or power tiller, these are large in size can not work for low inter row spaced crops. The portable knapsack power weeder is evaluated two different crops such as maize and chilliwith each blade (2, 4 and 6 blades per flange) combination. During the evaluation field capacity, field efficiency, weeding efficiency, plant damage, fuel consumption, performance index were evaluated. Actual field capacity of weeder for maize and chillicrop with 6 blades was 0.023 ha/hand 0.025 ha/h. Field efficiency of weeder for maize and chilli crop was 61.3 per cent and 66. 6.Weeding efficiency for maize and chilli crop was 89.3 per cent and 85.2 per cent. Plant damage for maize and chillicrop was 2.4 per cent and 3.30 per cent.Keywords
