Impact of irrigation regime and land levelling on infiltration characteristics, water relations and yield of wheat and corn in clay soils [electronic resource].

Field experiments were carried out during four successive winter and summer seasons at Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt. These experiments aimed to evaluate the impact of border and furrow irrigation systems, under different land levelling practices, on infiltration characteristics of the soil, water relations and yield of wheat and corn. Experiments were arranged for each crop in split plot design with three replicates. Main plots were assigned to land levelling practices (dead and traditional levelling), while the subplot treatments were the continuous flow irrigation and four cycle ratios of surge flow irrigation. Obtained data showed that water infiltration rate of the soil is reduced and bulk density of surface layers increased using surge flow irrigation. This was more pronounced under the dead levelling than under the traditional one. Reducing infiltration rate with surge flow irrigation was advantageous in several aspects.
