Description The investigation entitled “ Ergonomic Evaluation of Harvest and Post Harvest
Activities Performed by Female Labourers in Sorghum Crop with Agricultural Tools” was
carried out during 2005- 07 in Dharwad district of Karnataka state. A total of 160
respondents were selected randomly for the study. Further, the identified maximum drudgery
prone activity was ergonomically evaluated by improved implements, on the 30 healthy
female labourers for cutting stalks and threshing of sorghum crop. Cutting stalk and threshing
was identified as maximum drudgery prone activities among harvest and post harvest
operations .The mean working heart rate of the female labourers while working with the
improved I-104 sickle was found to be least (123.22 beats/ min) compared to traditional
sickle (130.72 beats/mins). Rating of perceived exertion by the female labourers for cutting
stalks by sickle I-104 was less compared to other improved sickles. The mean working heart
rate and energy expenditure was higher (118.42beats/min) for threshing with thresher
compared with the wooden beater (108.30beats/min). Threshing activity as perceived higher
by the respondents with the thresher over wooden beater. Majority of the female labourers
expressed exertion towards cutting stalks with CIAE Bhopal sickle as very heavy. The total
postural changes made by the respondents with improved sickle CIAE Bhopal were higher
compared to traditional and other improved sickles in cutting stalks. Majority of the
respondents expressed very severe pain (53.3 %) in wrist/hand with the use of traditional
sickle. The musculoskeletal problems expressed by the female labourers were found to be
higher with the thresher for threshing of sorghum crop. The larger area and maximum output
was found with improved sickle I-104 (30.70 sq.mts and 94.95 kg) in cutting stalks. The
output was found to be more for threshing with the thresher (ear heads – 301.82 kg and seeds-
237.10 kg).
