Abstract

Field experiment was conducted at Sandy Loam Soil, classified as Typic Torrifluvent ,during Fall season 2005-2006 ,to study effect of Surge irrigation system on some parameters of water discharge of Zea Mays yield class/Ebaa (5012) ,to compare with conventional irrigation system (continuous irrigation),The cycle ratio of 1/2 at Surge irrigation, and discharge of 2.5 L.sec-1 for both systems were adopted. RCBD ( Randomized complete block design),was applied in this experiment factorial.
Different ratio for increasing of water saved at Surge irrigation were obtained ,%15 for fifth first irrigation ,while it was reached %12.10 for twelve irrigation ,because high speed of Advance phase ,The ratio of Infiltration rate was decreased %41.10,and %43.55 for Basic infiltration rate ,which had obtained at beginning of second Surge , At beginning of second and third Surges Infiltration was stopped about one minute, and cumulative infiltration had been decreased from 53.17 cm to 31.39 cm among 8 hrs.
Surge irrigation system led to increasing irrigation efficiency from %44.90 to %69.50.and (WUE) from 0.99 kg.m-3 to 1.16 kg.-3 .yield of corn was increased from 7817 kg.ha-1 to 8036 kg.ha-1, Water discharge reached to 694.4 mm at Surge irrigation system.
