Abstract
The herbicide butralin (Amex) was injected at the recommended rate ( 2.5 Kg/fed) through subsurface and surface drip irrigation systems with two flow rates of 8 and12 lph/m under sandy soil conditions of the newly reclaimed areas of Egypt.
Maximum cucumber yield of 8360 kg/fed. was achieved using subsurface drip irrigation systems at 8 lph/m flow rate and 50 cm emitters spacing, in manure sandy soil Water use efficiency (WUE) ranged from 4.042 to 3.955 kg/m3 with 8 and 12 lph/m flow rates, respectively for subsurface irrigation systems 50 and 33 cm emitters spacing in manured sandy soil. The application of herbicide butralin (Amex) with subsurface drip irrigation systems, 50 cm emitters spacing proved more suitable to increase cucumber yield, and to achieve more uniformity in water distribution (8 lph/m) for irrigation systems. No butralin (Amex) residues were detected in cucumber yield produced under subsurface drip irrigation systems at 10 cm depth for the 50 cm emitters spacing and 8 lph/m flow rate.
