| Abstract | ||||
| The best method for applying and spreading water, as well as for providing plants with nutrients, has long been thought to be drip irrigation systems. A field experiment was carried out in 2022 during the planting season to examine the impact of drip irrigation systems on the production of maize (White Triple Hybrid 324) on the Giza research station farm, Giza governorate (18 m above sea level, 30^34/N latitude, 29˚55/E longitude). Two types of laterals (T-tape and GR) and two distinct lateral designs (double and single inlets) were assessed for use with subsurface and surface drip irrigation systems. This study's primary objective was to evaluate conventional irrigation with single and double intake irrigation in terms of soil moisture, corn yield, and water consumption efficiency under two different lateral types—GR and T-tape—with a 50-meter lateral length. The results demonstrated that, in comparison to single inlet irrigation, double inlet irrigation and the type of lateral T-tape improved irrigation water use efficiency (WUE) by increasing soil moisture content at soil profile and grain yield percentage, especially when applied under varying lateral lengths. Under the length of the lateral expansion in a drip irrigation system, the yield and water use efficiency declined. At varying lateral lengths, T-tape treatment typically resulted in increases yield, water use efficiency, soil moisture emission uniformity, and yield compared to GR treatment. | ||||
