The Effect of some Irrigation Methods and Moisture Depletion percent in the Growth and Productivity of Corn

The experiment was conducted in the fields of Al-Hilla - Babylon province, with loam soil, during autumn season 2021, to study effect different irrigation methods and levels depletions on growth yield corn (Zea mays L.). Randomized Complete Block Design (RCBD) an as complete split plot three replications, main included treatment depletion subplot systems, treatments were distributed experimental plots randomly. Irrigation systems subsurface drip surface furrows, for each 20%, 40%, 60%. result showed that 40% achieved highest plant height (206.92). While there no significant difference treatment. furrows system has lowest height, which reached (174.14). There are differences between level area leaves plant. Also, used did not significantly affect weight depth roots, while values ​​of water rates.
