This paper described the overall mechanisation status in the cultivation of sweet corn in Malaysia and the machinery energy, worker’s energy expenditure and heart rate for the various flied operations that were involved in cultivation. The field operations include tillage, planting, fertilising, spraying, harvesting, and cutting. Field capacity and machinery energy for each of the operations were calculated. The calculated mechanization index was used in the study to describe the mechanization status in sweet corn cultivation. A mean overall mechanisation index of 38.62 % and an aggregate machinery energy of 281.00 ± 34.51 MJ/ha were registered for the crop. Highest mechanisation index and machinery energy were acquired in the tillage operation (94.09% and 105.35 ± 9.37 MJ/ha) while the lowest mechanisation index and machinery energy were in the fertilising operation (5.15 % and 2.504 ± 0.30MJ/ha). These calculated mechanization indexes were useful for ranking the field operations based on their priority for mechanization.
