TRICKLE IRRIGATION SYSTEMS IMPROVING BY USING BYPASS-TECHNIQUE
It’s a fact that trickle irrigation systems became a major part for developing agriculture in Egypt for that, the aim of this research was reaching the highest values from irrigation systems management as the result of using bypass-technique, this new technique was done by installing microtubes at third last of trickle line. The laboratory experiments were carried out at the National Irrigation Laboratory of Agricultural Engineering Research Institute. The laterals were tested and calibrated under different operating pressure (0.50 - 0.75 – 1.00 -1.25 bar) for measuring emitter flow rates and determining emitter’s emission uniformity (EU) and its manufacture (CV). The following results were found:-
1- The emitters’ performance was determined by using relationship between emitter flow rates (L/h) and operating pressure (bar), data indicated that the emission uniformity (EU) was 95.68% (Excellent), at CV of 3.78% (Excellent) according to test standard (ASAE 1996) and actual flow rate was 14.08 l/h.
2- Installing microtubes., distance between emitters=0.5, 1.5 and 3 meters, present the following results respectively, where emission uniformity equal to 90.9%, 96.28% and 98.06 % (Excellent) in compare with traditional which in range of 89.34%, 95.52% and 96.03% respectively, emitters performance equation which was been in power relation in between average of flow rates (L/h) and pressure (bar).
It is recommended that bypass-technique gave a new advantage for trickle irrigation systems.
