Many parts of the world including Egypt currently suffer from water scarcity. For this reason optimization of the available water has become a necessity not only from the point of limited water resources, but also relative to the growing demand for food. Field experiments were conducted at Experimental Farm of National Research Center, El-Nubaria, El-Buhaira Governorate, Western Delta, Egypt to study the effect of automatic control of the localized irrigation system(LIS) as a modified system on emitter's clogging and maize parameters in new reclaimed lands by using the following treatments: a) Bubbler irrigation systems (B); b) Low head drip irrigation system (LHD), and c) Mini-sprinkler irrigation system (MS) through different lateral lengths (40, 50; 60m). Plants were irrigated every 4 days to compensate ETc and salt leaching requirement took place. The obtained data showed that emitter's clogging percentage could be ranked in the ascending orders: LHD
