Effect of different irrigation treatments on growth and yield of barley crop

الملخص EN

An experimental study was carr ied out to estimate the effect of different irrigatio n levels on growth and productivity of barle ycro p.

Th e experiment was conducted at Hada Al-Sh arn Sta tion of King Abdulaziz University in Saudi Arabia.

The irrigation treatments were designed based o n the depletion rat io meth od, where, the considered depl et ion rati os for the tre atments were 50%, 30%, and 10% from the tot al available wate r in soilroo t depth .

The applied irrigation water, and the irr igation interv als correspon ding to the differen t irrigation tr eatments were calculat ed .

The soilwater properties and interrel at ionshi p were mea sured in field and laboratory .

The flood irrigation system (basin meth od ) was applied for irrigati on.

The main conclusions of the study are th at , the irrigation levels have a highly significant effect on the crop dry yield than th at of the oth er plant variables.

Meanwhile , the crop yield is increased as the applied depl etion percent age is decreased.
