Abstract | A study was undertaken to evaluate the human energy consumption of various field operations involved in lowland rice cultivation in Malaysia. Based on recorded average heart rates, fertilizing was found to be the most strenuous operation,with an average heart rate of 138 beats min-1. There were no significant differences in the average heart rates of the subjects among the individual tasks within the first plowing, second plowing, and harvesting operations, with the average heart rates for these three tasks being 116, 106, and 106 beats min-1, respectively. The corresponding energy expenditures were 3.90, 3.43, and 3.35 kcal min-1. Loading the seed into the blower tank and broadcasting the seed were the most critical tasks for the seed broadcasting operation, with average heart rates of 124 and 136 beats min-1, respectively. The highest energy expenditure of 418.38 kcal ha-1 was observed for seed broadcasting,and the lowest energy expenditure of 127.96 kcal ha-1 was for second plowing. The total seasonal human energy expenditure for rice cultivation was estimated to be |
