Sugar beet is considered as one of the most important crops for Egypt and on global scope as it is vital source of producing sugar .The research investigated the production operations of sugar beet with the vision of minimizing the total emergy input and the zero waste sugar beet production system . Experiments were conducted at the Agricultural Experimental station , Faculty of agriculture , Cairo University . Three tillage equipment , pneumatic planting , topping and digging for harvesting were tested . the vegetative topped part was composted . Over all agronomical , technical and emergy analysis were carried out for evaluation . The obtained results revealed that the chisel plowing followed by disc harrowing consumed the lowest amount of emergy . the over all emergy consumption of the tested operations was 46.52 kW.h/fed .The harvesting operation by mower followed by digging coused total damage of 10.16 ton/ fed.The main out comes of the research recommended using chisel plough at 6Km/h and 10cm depth followed by disk harrow , pneumatic planter in planting then mower ,chisel plough in harvesting that achieved the value optimum in emergy consumption and yield
