The energy consumption for ploughs is range from 462.00 to 1,290.26 MJ/Rai. It is depending on times of plough.The energy consumption for water pumping is average 55.74 MJ/Rai.So, the energy consumption for Soil preparation process is 462.00 - 1,346.00 MJ/Rai The energy consumption of Soil preparation process is shown in Table 2.
