Ergonomic Evaluation of Women Farm Workers Using Different Manual Weeding Tools in Maize Crop of Udaipur District

Women play a major and crucial role in doing the agricultural operations. The women workers in Udaipur district mostly uses sickle and kudali for doing weeding operations. This study was conducted in 2019-20 at instructional Farm, CTAE, Udaipur with women farm workers during the manual weeding operation by using different traditional tools like hand hoe (kudali) along with technically and ergonomically designed wheel hand hoe. The main objective of the study was to investigate the most drudgery prone tool and to recommend the proper tool for doing weeding operations in maize crop. Use of proper tools not only reduce the drudgery but also improves the operating efficiency along with the comfort, besides improving the productivity of the women farm workers in doing the operation. In view of this, an effort has been made to assess the physical and physiological parameters of women farm workers who are using traditional farm tools along with the improved tools for doing weeding operation in maize crop. The whole study was conducted on ten female farm workers identified from the population of workers in the age group of 18 to 45 years. During the experiment, physiological workload i.e., heart rate, oxygen consumption rate, energy expenditure rate and physical workload i.e., overall discomfort rate, rate of perceived exertion and Musculo-skeletal problems were measured. The Pratap wheel hand hoe saves nearly 36% of the cardiac cost of the worker per unit of output and wheel hand hoe saves nearly 38% of the cardiac cost of the worker per unit of output which is nothing but reduction in drudgery by 36% and 38% by both the weeding tools over kudali. Area covered with Pratap wheel hand hoe and wheel hand hoe were 1.70 and 1.69 times more over kudali.
