Abstract

A field experiment was conducted in a sandy loam soil containing 16.60% gypsum, to study the effect surge irrigation and continuous irrigation on some infiltration characteristics and on the ratio of water saving in broad furrow irrigation . Complete randomizing design ,with three replicates per treatment was used in this study ,and the important results were decreasing in the advance time water front in the case of continuous irrigation with significant differences with the passage of time from the first irrigation where it was 2.68 minutes and even tenth irrigation where became 2.43 minutes. and increased the time of advance phase with significant differences also in the case of surge irrigation with the passage of time from the first irrigation where it was 2.60 minutes ,and even eighth irrigation reaching 3.2 minutes . the total time for irrigation and the amount of water added are the least with significant differences in the case of surge irrigation until the eighth irrigation. providing high water when we follow the method of surge irrigation from the first irrigation, reaching 8.90% then decreased with time to 3.34%at the eighth irrigation with significant differences , and it is lack of irrigation in the ninth and tenth, and low rates infiltration in the case of surge irrigation during the time of irrigation reaching 18.66cm.h-1 compared with 20.26 cm.h-1 in the case of continuous irrigation ,but without significant differences. resulted in the passage of time with repeat irrigation to reduce the rates of infiltration with significant differences in both irrigation method for following .increase the rate of the advance pace of the water front with significant differences in both the second and third surge ,reaching 3.91 m.minutes-1 and 4.05 m.minutes-1 respectively ,compared with 2.62 m.minutes-1 of the first surge, and this is in the case of surge irrigation.
Results of this work indicate that the method of surge irrigation is also suitable for the broad furrow irrigation ,and this achieved through the saving of irrigation water ,for this we recommend using it when planting crops that are more successful in this type of furrow .
