Abstract:
A study was conducted on an ergonomic assessment of manually operated chisel weeder at agriculture working field (10 10 m². Anthropometric data of age group operators of (25-40 years) were determined. Heart rate, oxygen consumption rate, energy expenditure rate and body part discomfort score of physiological and postural parameters of age groups were determined during working on chisel weeder at agriculture working field. Anthropometric data of stature, arm length, standing eye height, knee height, elbow height and body mass index were determined for different age groups. Heart rate, oxygen consumption rate, energy expenditure rate and body part discomfort score were increasing when age groups increased at weight sample (1.5, 2.0 & 2.5 kg). Heart rate, oxygen consumption rate, energy expenditure rate and body part discomfort score of 20-24 yrs age groups were found minimum and varied from 89-108 b/min, 0.32-0.555 l/min, 6.96-11.49 kJ/min and 17.74-21.38 respectively during working. Heart rate, oxygen consumption rate, energy expenditure rate and body part discomfort score of 35-39yrs age groups were found maximum and varied from 95-130 b/min, 0.40-0.80 l/min, 8.40-16.68 kJ/min and 42.92-53.32 respectively operators on paddy transplanter at different weight samples.
