الملخص الإنجليزي

A Field experiment was conducted during the season 2016-2017 in AlMahaweel Research Station in Babel Governorate /Ministry of Agriculture to determine the role of irrigation and water quality on water productivity of two wheat varieties IPA 99 and Al-Rasheed 22 in clay loam soil classified as Typic Torriflovent.

The experiment included four irrigation treatments: River water irrigation (I0), Salty well water irrigation (I1), Alternate irrigation one irrigation with river water followed by two irrigation with well water (I2) and Traditional farmer irrigation treatment (I3).

Two varieties of wheat IPA 99 (V1) and AlRasheed 22 (V2).

The experimental lay out was randomized complete block design (RCBD) with three replications.

Wheat grains IPA 99 and Al-Rasheed 22 varieties were planted in 23/11/2016 and harvest in 13/5/2017.

Determine the amount and period irrigation depended on sensors reading of volumetric water content was measured using GS3 sensors.

Irrigation water was applied at 50% depletion to the depth of effective root zone and calculate depth of water applied up to field capacity.

Amount of irrigation water to the local farmer irrigation was determined according to traditional irrigation schedule by farmer up to field capacity in addition to taking sensors readings continuously for soil moisture and electrical conductivity to follow-up the salinity changes in soil profile for two depths 0.20 and 0.40 m from the surface soil in time intervals of four hours among readings along the growing season, then determining the final reading of electrical conductivity of soil according to the changes of soil temperature during agriculture season after using many comparing equations.

The most important results can be summarized: 1.

The actual water consumptive use (ETa) for wheat IPA 99 and Al-Rasheed 22 were 526.5 and 523.6 mm season-1 for river water irrigation (I0) respectively.

The actual water consumption use (ETa) were decrease for I1, I2 and I3 of 14.76, 1.41 and 15.19% for IPA 99 and 13.69, 1.34 and 13.50% for Al-Rasheed 22 respectively compared to I0 treatment.

2.

The amount of irrigation water added varied with a variation of irrigation treatments I0, I1, I2 and I3.

The amounts were 4938, 4141, 4864 and 4138 m3 ha-1 for IPA 99 and 4909, 4172, 4829 and 4192 m3 ha-1 for Al-Rasheed 22 respectively, irrigation water quantity added varied depending on the sensor's reading.

3.

Al-Rasheed 22 gave the highest in grain yield and biological yield characteristics the amount was 5385, 2655, 5119 and 5241 kg ha-1 for irrigation treatment I0, I1, I2 and I3 respectively for Al-Rasheed 22 and 5200, 2313, 4877 and 4976 kg ha-1 for IPA 99 grain yield.
