Hydraulic Studies of Drip Irrigation System under Using Low Quality Water Conditions II- Moisture and Salinity Distribution Patterns

Keywords : Emitter type, water salinity


Abstract

Water characteristics have the majority effect on moisture and salinity distribution. Therefore, the aim of this study was to evaluate the distribution of moisture and salinity under drip irrigation system and saline-water conditions. Field experiment was carried out at Research and Production Station, NRC, Nubaria District, El-Beheara Governorate, Egypt, during 2015/2016 growing season to study the effect of the selected emitter's types under different irrigation water salinity on the water and salt distribution patterns. The experiment was conducted under three emitter types [Non pressure compensating 1emitter (NPC1), Non pressure compensating 2 emitter (NPC2), and Non-pressure compensating 3 emitter (NPC3)] under water salinity (345, 2000, and 4000ppm).
