الملخص الإنجليزي

The objective of the study was to estimate the crop water requirement of wheat with bio fertilization using as soil properties demented.

The study was carried out in field of in Al- Diwaniyah province and Babel province/ Iraq during winter season 2017-2018.

The experimental design with factorial experimental was used Randomized Complete Block Design including ten treatments in three replicates.

The first factor irrigation including five treatments (full irrigation (control), irrigation was imposed at 55% depletion of available water).

The non complete irrigation omitting two irrigation at tillering stage, joinfing stage, flowering and growth grain stage.

Whereas the second one was with and without addition of bio fertilizers.

The water content of depletion water for 0-0.2m layer was calculated from planning till shoot growth and increasing of irrigation water depth to include 0-0.4m during flowering and yield formation stages.

All agricultural processes for crop management were used according to recommendation.

Actual evapotranspiration was estimate using water balance equation.

The result showed that control treatment had highest consumptive water 512 and 488 mm in Al- Diwaniyah province and Babel province, respectively and decreasing to 472 and 463 mm at control irrigation treatments with bio fertilizers addition in Al- Diwaniyah province and Babel province, respectively.

This closeness between values of irrigation and ETa can be related to high irrigation efficiency and using of active deep according the plant developing stages in this study because of the minimization of water losses as deep percolation, also deficit irrigation treatments decreased ETa.

There is no significant differences in grain yield between the control treatment and deficit irrigation treatments at joinfing, growth grain stage.

This result pointed that stages are law sensitive to water stress.

At the same time we found increase in water productivity in this treatments compare to full irrigation treatment.
