摘要

The original IRRI manual single-row cono-weeder that is widely used in Indian lowland rice fields since eighties was modified by giving due ergonomic consideration in the investigation and comparison was made with the measured parameters to ascertain the improved comfort of the operator. The ergonomical evaluation of three makes in lowland rice with twelve female subjects reveals that the operation of all weeders is graded as 'heavy' with respect to energy expenditure. Since the mean oxygen consumption rate of female subjects as percentage of VO_2 max are above the acceptable work load (W_1: 72.0 %, W_2: 76.2 %, W_3: 82.8 %), rest pause of 7.4, 10.5, and 12.9 min respectively for every 45 min of operation was recommended to overcome the problem of fatigue. Discomfort rating was on par with all weeders and they are above the limit of moderate discomfort. In view of body part discomfort score of the subjects, W_1 regis- tered the lowest discomfort. Force requirement in push and pull mode was 36.4, 35.1 N with W_1, 37.5, 37.0 N with W_2, and 43.3, 43.1 N with W_3 respectively. The adoption of weeders with improved ergonomic design features in W_1 and W_2 enhanced the comfort of the subjects with respect to prominent ergonomic parameters. It was concluded that the human factors engineering interventions that have been given to the single-row manual cono-weeders in the study have proved its superiority in lowland rice.
