In recent years, due to drought, it has focused on promoting the use of drip irrigation in the country. Due to the lack of available water resources, farmers have also realized the need to use a drip irrigation system. If the scientific principles in the use, design and operation of these irrigation systems have not been considered thoroughly, this method will not be useful and result in capital loss. Dates are one of the garden products that play an important role in food security and national economy. Hence the purpose of this research is technical and hydraulic evaluation of the performance of localized irrigation system (bubbler) on palm trees located in Bastak city in Hormozgan province and also comparing water productivity of this method with the basin irrigation system, which is common in this area for this purpose, two farms were selected for the above research in the city Evaluation parameters were measured by measuring the flow rate and pressure of the bubblers in two stages. The results of this study showed that the values obtained for potential application efficiency of low quarter and actual efficiency application of low quarter (PELQ and AELQ), which represent the overall performance of the localized irrigation system (bubbler) in the evaluation made on March 2019, was 29.21% and 32.44%, respectively, and in the evaluation conducted on June 2019, was 32.64% and 36.26%, respectively. Bubbler localized irrigation system is evaluated in a poor condition.
