A farm level evaluation of fuel consumption and the resulting Carbon Dioxide (CO_2) emission in wetland rice cultivation was conducted in 40 farms, in Malaysia. Analysis of the results showed that the mean total fuel consumption for the entire cultivation operation was 59.57 l/ha with corresponding total CO_2 emission of 153.80 kg/ha. The highest fuel consumption was in tillage and the lowest was in planting operation with corresponding values of 21.39 and 1.10 l/ha respectively. Fuel consumption in tillage was significantly affected by number of passes, field condition and type of implement used. A decreasing trend in fuel consumption rate of about 0.04 l/min was observed with increases in the number of tillage passes. Tractor-rotary tiller combination consumed about 14% more fuel to that of tractor-chisel plow combination. Fuel consumption rate of tractors was lower in wet fields (0.09 l/min) by about 31% compared to in dry fields. Estimated government subsidy on fuel in rice cultivation is about RM45.58/ha amounting to more than RM31 million/year at country level.
