Abstract
Weeds are the major biotic confinements of rice productivity. In Bangladesh, weeding operation is done manually pulling or by using simple tools like khurpi, push-pull Japanese weeder, BRRI, BARI and locally developed weeder. The main objective of the research work was to assess the ergonomic factors of BRRI multi-row power operated weeder. This study was carried out in the cultivators’ land, Tarhat Para, Gazipur Sadar under silty loam soil condition during Boro season, 2018-2019. Three operators were casually selected for ergonomic evaluation. Heart rate was measured every 30 minutes during operation. Body mass index (BMI) values were found to be 24.05, 21.48 and 23.48 kg m-2 for operators O1, O2 and O3 respectively. The mean working heart rate for operating BRRI multi-row power weeder was found to be 134.67, 137.33 and 138.67 beats min-1 and the equivalent average energy expenditure rate was found to be 28.61, 29.72 and 30.28 kJ min-1 during weeding operation for operators O1, O2 and O3 respectively. The oxygen consumption rate was differing from 0.86 to 0.90 l min-1. The rest pause during weeding operation was found to be 11 minutes followed by 30 minutes of operation. Based on the workload, the operation of BRRI multi-row power paddy weeder is ergonomically safe and it could be operated continually upto 8 hours of a long day if 11 minutes of work rest time to a operator may be taken after 30 minutes of operation.
Key Words: Body mass index, Oxygen consumption rate, Energy expenditure rate and Rest pause during work
