Abstract | ||||
The objective of evaluating surface irrigation systems is to identify management practices and system configurations that can be feasibly and effectively implemented to improve the irrigation efficiency. Two field experiments were conducted at Sakha Agricultural Research Station, Kafr Elshiekh Governorate during two successive summer seasons (2006 and 2007) to study the evaluation of surge, alternative and continuous flow in furrow irrigation with cotton crop. A randomized complete block design with four replicates was used and the irrigation treatments were as follows; surge flow with cycle ratio 0.5 (5 min. on and 5 min. off or 10 min. on and 10 min. off), surge flow with cycle ratio 0.66 (10 min. on and 5 min. off or 20 min. on and 10 min. off), surge flow with cycle ratio 0.75 (15 min. on and 5 min. off or 30 min. on and 10 min. off), alternative furrow irrigation and continuous flow. The results indicated that the performance of the system during the evaluation was acceptable in case of surge flow at 0.75 cycle ratio with 30 min. on and 10 min. off in the two growing seasons. In case of continuous flow, the performance of the system was poor since about 48 percent of all water applied was lost from the field as runoff or deep percolation. | ||||
