The ultimate purpose of the study is to reveal the reacts of in-line drippers’ hydraulic performance emerging from the differences in the production process and the different technical features to flow changes; however, the drippers were produced in different companies at different rates of flow and technical features. In order to reveal the relationship of drippers’ pressure-flow, 3 different types of inline drippers have been used 51 pieces of drippers have been selected for each type of drippers and totally 153 tests have been carried out. Tests have been performed 0.5, 1, 1.5 and 2.0 atm pressure values. At the end of the research, it has been proved that the relationship of in-line drippers and pressure-flow is in directed proportionate. The results obtained from the following coefficiency tests; Manufacturing Variation (CVm), the Emission Uniformity (EU), Christiansen Uniformity (Cu) and Statistical Uniformity (Us), have showed that these coefficiencies have been observed higher (perfect rank) in pressure unregulated in-line drippers than the other types of drippers.
