In: Misr Journal of Agricultural Engineering 2009.v.26(2)Part 2Summary: A field experiment was carried out at the Experimental Station Farm, Faculty of Agriculture, Cairo University. The purpose of this study is to investigate the effect of different levels of soil surface compaction pressure (P) (15, 22.5, 30, 37.5 kPa) and compacting cylinder surface shapes (C) with protrusion spaces (5, 10, 15 and 20 cm) on: the infiltration rate (IR), percentage of water losses by deep percolation (DPP), percentage of soil moisture defect (SMD), total advance time (AT), water distribution uniformity (Du), water application efficiency (Ea), the corn crop yield (Cy) and the water use efficiency (WUE). All data were collected during the summer seasons of 2004 and 2005 for corn crop. For the compacted soil surface, the values of IR, DPP, SMD and AT decreased by increasing the soil surface compacting to 22.5 kPa and by increasing protrusion space to 15 cm. The values of Du and Ea increased by increasing the soil surface compacting to 22.5 kPa and by increasing protrusion space to 15 cm. The best Cy and WUE were obtained at soil surface compacting (P2) 22.5 kPa, with any compaction cylinder surface shape.
