Abstract

In order to evaluate the effect of three irrigation methods including Surface irrigation (I1), daily Sprinkler irrigation (I2), post-irrigation sprinkling with fresh water (I3), and different levels of salinity including 2. 9 (control), 3. 5, 4. 1, 4. 7 and 5. 3 dS. m-1 on agronomic and physiological traits of maize, a field experiment as factorial was carried out based on randomized complete block design with three replications during 2013-2014 in College of Irrigation science, Shahid Chamran University of Ahvaz. To apply salinity, a Sprinkler irrigation system was used to establish minimum and maximum salinity levels on two parallel pipelines on both sides of field. Overlapping sprinklers led to establish a linear salinity gradient. Irrigation methods I3 and I2 with 4750 and 4160 kg h-1 had higher and lower amounts of grain yield, respectively. Water salinity significantly decreased stomatal conductance, chlorophyll index, leaf area index, K+ concentration and ratio of potassium to Sodium, and higher reductions in these traits was observed in Sprinkler irrigation. Daily Sprinkler irrigation and Surface irrigation showed the higher and lower Na+ concentration, 18. 2 and 15. 1 mg kg-1, respectively. These findings showed that, the threshold value of salinity for most traits and all irrigation methods was found to be ~4. 1 dS. m-1. With the given water resources limataion and saline water resources in Iran, post-irrigation sprinkling with fresh water might be used for irrigating row crops such as maize with a lower yeild loss.
