Therefore this study was conducted to select the most suitable maintenance program for improving drip irrigation systems and laterals performance. The experiments carried out to study the effect of maintenance programs were divided into two main flushing procedures (MP₁: Flushing with fresh water), including three sub main programs (MS₁P₁, MS₂P₁, MS₃P₁), each of them was studied in four interval time, "weekly, bi-weekly, monthly, and at the end of the season UR - http://172.23.153.220/th.pdf ER -
