Field experiments were carried out at the Sakha Agricultural Research Station, Water Requirement Department, Kafr El-Sheikh Governorate, Egypt, during the growing season of 2004/2005. This study was conducted to determine the effect of soil preparation on water requirement and sugarbeet yield. Soil characteristics (bulk density, porosity, infiltration rate and soil pulverization) were measured under four different tillage systems. Also, fuel consumption, slippage and field capacity, power and energy requirements, total cost of seedbed preparation systems, water applied and yield components, were determined. Results indicated a clear significant in relative increase of soil volume, rate of disturbed soil and yield. The highest value of soil pulverization degree was 95.11% for chisel ploughing (two passes) followed by rotary tillage. On the other hand, the minimum value (78.85%) was achieved using mouldboard plough followed by rotary tiller. The highest value of energy requirement was 27.23 kWh/fed for mouldboard ploughing, and the minimum value was 12.04 kWh/fed for disc harrowing (two passes). The total cost of two passes of disc harrow was cheaper, reaching 18.8 E/fed; meanwhile, chisel ploughing with two passes followed by rotary tillage cost approximately 46 E/fed. The maximum water consumed in mouldboard ploughing followed by rotary tillage was 2390.64 m3/fed. However, the minimum value was 2035 m3/fed for chisel ploughing with one pass followed by rotary tillage. Mouldboard ploughing followed by rotary tillage gave the maximum value 12.55 kg/m3 of water use efficiency. While, the minimum value was 8.97 kg/m3 for chisel ploughing with one pass followed by rotary tillage. The maximum value of root yield 30 tonnes/fed was achieved by mouldboard ploughing followed by rotary tillage. Whilst, chisel ploughing followed by rotary tillage gave the minimum value of 18.260 tonnes/fed.
