The agricultural irrigated area depends on the availability of sufficient quantities of suitable quality of irrigation water, but with the large scale increases in agriculture and the shortage in good quality water resources, lead to the necessity of Using the available water in the most proper way. For that this study was designed to discuss the effect of the type of water on the soil, crops and its effect on the emitters.
A field experiment has been applied to study the effect of different irrigation water treatments. Therefore four treatments of irrigation water (100%, 80%, 50% and 0%) irrigation water and the rest is drainage water.
Four types of emitters, were chosen to represent the most common types of emitters which exists in the local market, and used in irrigating the vegetable crops, online emitters as HO, inline emitter as GR, pressure compensating emitters as KA and pressure compensating and self flushing as MF.
Results showed that the soil was affected by the irrigation water salinity. The water EC increased as well as the pH mainly for the 100% drainage water treatment and this influence decreased for the other three treatments. The MF emitter is the most stable emitter and had a Suitable application efficiency and has not been affected by the irrigation treatment, but its high price eliminate it's use in irrigation vegetable crops, therefore it can be cleared the GR emitter is the most suitable emitter while it came in the second place, but it is not that expensive and available for ordinary farmers.
And also the 80% irrigation water & 20% drainage water can be used with little change in the yield than the yield of the irrigation water treatment.
