Abstract :

A hand-pushed mechanical weeder was developed and evaluated to determine its performance indices. The field performance was compared with traditional hand-held hoe on a variety of TZPB-SR maize crop grown field. The means of forward speed, actual field capacity and weeding efficiency are 0.092 m/s,0.028 ha/hr and 75.17% for the developed weeder as against 0.013 m/s, 0.0059 ha/hr and 77.98% for the manual hoe respectively. The mean effective operation time for the developed weeder on a 9 x10-4 ha field of a sandy loam soil at 14.85% moisture content was found to be 91 second with 164 number of weeds removed while that of traditional hoe was found to be 189 seconds with 153 number of weeds removed on the same size of field.
