| Abstract | ||||
| Sprinkler irrigation is a relatively new method in Egypt mainly used in the newly reclaimed desert areas, while surface irrigation systems are dominent in old heavy texture soil areas. The main objective of the present study was to investigate the possibility of using sprinkler irrigation system in cotton crop production in the old valley by studying its effect in minimizing water losses and increasing cotton yield. Measured performance parameters and water utilization efficiencies were also studied for both sprinkler and surface irrigation systems. Results indicate that sprinkler irrigation system saved 17.81% of water applied and increased the yield by 22.6% compared to surface irrigation. The water utilization efficiency increased by 51.2% in sprinkler system compared to surface irrigation system. | ||||
