| Abstract | ||
| the aim of this study is to reduce Peas contamination with herbicide by applying chemigation in new reclaimed lands through drip irrigation systems. The herbicide (butralin) was injected with recommended rate (2.5 Kg/Fed) through subsurface and surface drip irrigation systems with two flow rates of 8 and 12 l/h/m tube under sandy soil conditions in winter and summer seasons 2016. The results showed that the highest productivity of the peas was (5570 kg / Fed) with water use efficiency (WUE) of (2.31 Kg / m3) and more uniformity under the following conditions: the subsurface drip irrigation system at an flow rate of 8 l / h/m – tube (dripper flow rate of 4 l/h) and 50 cm emitters spacing, injection of the herbicide (butralin). It is wearthly to mention that no (butralin) residues were found in Pea yield produced under subsurface drip irrigation systems (10 cm depth), 50 cm emitters spacing and 8 l/h/m flow rate under the manured sandy soil. | ||
