Due to scarcity of water and energy resources in Egypt, the objective of this study was to determine the ability of using unfiltered Nile Water (NW) and greywater (GW) with Drip irrigation. Drip irrigation is widely used in the new reclaimed areas with low operating pressure close to (20kPa). Field experiment was conducted from October 2010 to July 2011 in the Experimental farm, Suez Canal University to examine these conditions on the clogging of three emitters (EM) was used to irrigate three vegetable crops. Results obtained showed that, the clogging percentages were 75% and 35% with the emitter type (EM1), 69% and 39% with EM2 and 15% and 9% with EM3 when using NW and GW respectively. While pea plants showed a significantly higher yield (ton/ha) with NW, tomato plants, on the other hand, gave a significantly higher yield with GW. Cantaloupe plants showed varied results; GW gave 17% higher yield in contrast to fresh NW. The current study shows that the local emitter (EM3) is better than the other types and suggested that GW is a potential source for crop production by drip irrigation with some design and health considerations..(Download PDF) (Export to EndNotes)
