Energy is one of the most valuable inputs in crop production. Therefore, is necessary for efficient management of scarce resources for improving maize production. With this view, a field experiment was conducted during 2011-12 and 2012-13 at Indian Agricultural Research Institute, New Delhi to find out the effect of conservation agriculture practices and irrigation scheduling on energy requirement and dynamics in a maize production system. The finding revealed that conventional tillage requires higher energy input (45,960 MJ/ha) of which diesel consumption alone accounts for 86% of the total energy consumption in land preparation. Raised bed method of crop establishment requires lowest energy input (43,710 MJ/ha). Significantly higher output energy, energy balance, energy use sufficiency, energy output efficiency energy productivity and energy intensiveness was recorded in permanent raised bed with 40% available soil moisture deletion.
