Abstrakt: Manual work, which requires human muscle energy, is still common today despite automation and mechanization of activities especially in developing industries. Agricultural activities include land clearing, ridging/ mounding, planting and post harvest operations. There is presently limited data for energy requirements for making mounds for sowing of crops using manual hoes in Nigeria, necessitating this study. The participants in the study were a random sample of seven men and five women in two villages in Abeokuta, Ogun State. The subjects' heart rate HR was recorded before the mounding operation (HRR) and at the end (HRW). The energy expenditure of the farmers was determined using three models from the literature. The maximum energy expenditure obtained from the study was 12.92kJ/min (215.33 Watts) while the maximum work rate was 3.23 kJ/min (53.83 Watts). It was concluded that though mounding operations was a moderate work, there was the possibility of postural load, which would necessitate the design of appropriate simple motorized tools for mounding operations.
