Abstract

Ultra-low rate technologies are important method of irrigation to water management and save it from lose by runoff in heavy soils or deep percolation in sandy soils.
Ultra low – volume: extremely low water application rates, in the range of 0.1-0.3 l/h per emitter, change the water distribution pattern in soil and other growing beds. In this technology water can be applied to shallow rooted plants with minimum deep percolation.
The aim of these treatments is to investigate performance under three treatments by using low pressure. Results indicated that the use of pulse emitter (2 L/h) with GR tube (2 L/h) was the best in terms of the Emission Uniformity, which ranged from 90.2 to 93.7 when the operating pressure was 80 kPa and the flow rate was from 0.13 to 0.15 liters / hour.
