Abstract
Field experiments were carried out during 199511 996 and 1996/1997 growing seasons at Saklla Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt. These experiments aim to: 1. evaluate the border and furrow surge irrigation systems and different land levelling practices under the conditions of the heavy clayey soils of Kafi El- Sheikh governorate. 2, hprove efficiency of the surface irrigation and water saving. 3, defule the best surge flow f~~rroawnd border irrigation practices design for coril and wheat crops owing to optimize the water utilization efficiency. 4. evaluate the klpact of surge flow irrigation on some soil hydrophysical properties such as infiltration rate, bulk density and the fluctuation of ground water table. Wheat as winter crop followed by corn as summer crop were selected in an agricultural cycle. The rotation was repeated for two years. Sowing dates of wheat were 25”, 27”’ of Dec., 1995 arid 1996, while the corresponding dates of corn were 29’” and 30”’ of June, I996 arid 1997, respeclively. All cultural practices wcre the same as recolninended for the area except the irrigation and land levelling practice treatments. Dates of harvestu~g for wheat were June 1, 1996 and June 5, 1997. Wde, those of corn were Oct. 20, 1996 and Oct. 25, 1997. The experiment was arranged u.1 split plot design with three replicates. The inah plot was assigned to land levelling practices, wlde the subplot treatment was the conti~~uoiursri gation and four surge irrigation treatments. Each plot was 3.5 x 80 ln (280 m2 = 111 5 feddan). The treatments were as foIIows:
