Manual transplanting of vegetable saplings are labour intensive and time consuming operation. During the manual transplanting of saplings of vegetables, farm workers are highly affected by excessive physiological
workload and postural discomfort which are the major cause of human drudgery. Pace of work, time spent inÂ various activities, static body position and physiological and mental strain etc. are also the important factors which affect the work capacity of the farm workers. The study was undertaken to assess the physiologicalÂ workload and postural discomfort among farm workers during conventional method and mechanized method of vegetable sapling transplanting. Physiological parameters i.e. HR, energy expenditure, TCCW and PCW etc.were measured during transplanting operations. The center of gravity method was used to assess the posturalÂ discomfort among farm workers. Total 30 farm women were selected for the study. The results revealed that
working heart rate (HR work) of the subjects when the vegetable seedling transplanting was performed with conventional method ranged from 122.25 to 154.65 beats/min with a mean value of 135.65 Â± 9.54 beats/min. OCRÂ was found to be 1.06 Â± 0.38 and 0.54 Â± 0.43 l/min, respectively for manual and mechanized method of vegetableÂ transplanting.
