Evaluation of surge alternative and continuous flow in furrow irrigation with cotton crop at North Delta [electronic resource].

Includes references.

The objective of evaluating surface irrigation systems is to edentify management practices and system configurations that can be feasibly and effectively Implemented to imwove thE" irrigation efficiency, Two field experiments were conducted at Sakha Agricultural Research Stalion, 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 fOUf 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 mill. off). alternative furrow Irrigation and continuous fJow 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 mill off in the two growing seasons. Jn case of continuous flow, the performance of the system was poor SJI1ce about 48 percent of all water applied was lost from the field as runoff or deep percolation
