The present work was an attempt to study the energy use pattern in cropping systems in Southern Transition zone of Karnataka State. The most energy consuming system was sugarcane (97771.10 MJ/ha). Sugarcane being a highly labour intensive crop requires higher quantity of energy. Sugarcane was followed by Paddy-Groundnut, Paddy-Paddy system with their energy requirements of 49363.97 and 40193.48 MJ per ha respectively. The variation in energy consumption by cropping systems was due to the variation in input levels and intensities of field operations. Further analysis by sources of energy revealed that fertilizer was the major source of energy. Tillage operations were the most energy intensive farm operation. The energy use efficiency was again the highest in the sugarcane system as evident by its energy ratio.
