Abstract

Paddy is the major crop cultivated under wet land condition in the Konkan region of Maharashtra. Weed control is widely achieved by means of hand weeding which is labour-intensive, time consuming and costly. To reduce the drudgery involved in paddy weeding and enhance field capacity, the work was undertaken to develop a portable power weeder for paddy. The developed paddy weeder consisted of engine, gear box, propeller shaft, rotor with blade, main frame and float. Two types of blade one L shape and the other hexagonal serrated blade were designed and tested. The components viz., engine, gear box, rotor shaft, mudguard, float, handle, etc. were assembled and the final prototype developed was tested for its performance in field.  The rotor with serrated blade resulted in 9.41% higher weeding efficiency than "L" shape blade at 40 DAT (Days after transplanting). Rotor with "L" shape blade resulted in to 1.02% less plant damage as compared to serrated blade at 20 DAT. Higher (30.4%) field capacity was found with L shape blade (0.0266 ha h-1) as compared to serrated blade (0.0204 ha h-1) at 40 DAT. Minimum fuel consumption (0.576 L h-1) was found with ''L" shape rotor blade at 40 DAT, however, higher fuel consumption (0.646 L h-1) was observed using serrated blade at 40 DAT. The weeder with serrated blade had higher weeding efficiency.
