Abstract
Field experiments were carried out at Sakha Agricultural Research Station, Water Requirement Dept., Kafr El-Sheikh Governorate during the growing season of 2004/2005. The objective of the present study was to find out the effect of preparation on water requirement and sugar beet yield. Soil characteristics (bulk density, porosity, Infiltration rate and soil pulverization) were measured under four different tillage systems. In the same manner, fuel consumption, slippage and field capacity were undertaken. Power and energy requirements, total cost of seedbed preparation systems, water applied and yield components were calculated. The obtained results revealed the following points: 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 plough( two passes) followed by rotary Oiler. On the other hand, rt was reached its minimum value ( 78.85 %) by using mouldboard plough followed by rotary tiller. The highest value of energy requirement was 27.23 kW.h/fed; for 'mouldboard plough whilst, the minimum value was 12.04 kW.h/fed; for disk harrow (two passes). The total cost of disk harrow two passes was the cheaper where, it reached 18.8 L.E/fed; meanwhile, the chisel plough two passes followed by rotary tiller costed about 46 L.E/fed. The maximum value of water consumption was 2390.64 m'/fed; for mouldboard plough followed by rotary tiller. However, the minimum value was 2035 m3/fed; for chisel plough one pass followed by rotary tiller. Mouldboard plough followed by rotary tiller gave the maximum value of water use efficiency of 12.55 kg/m3. While, the minimum value was 8.97 kg/m3 for chisel plough one pass followed by rotary tiller The maximum value of root yield was found to be 30.00 mt/fed by using mouldboard plough followed by rotary tiller. Whilst, chisel plough followed by rotary tiler gave the minimum value of 18.260 mt/fed.
