Abstract
Ultra-low rate technologies are an important method of irrigation to water
management and save it from losing 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 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 l / h.
