Abstract EN

The experiment was carried out at Haweeja horticultural station belonging to the Kirkuk Agriculture Directorate / Ministry of Agriculture, in Haweeja district, located in the southwest of Kirkuk governorate, 66 km from the city center at longitude 43.77 Eo and latitude 35.30 No, 182 km from the center of Mosul for the summer season.

2020 For the period from 7/18/2020 to 10/1/2020.

To study four types of drippers (GR-Spiral-T-Tape-Turbo and three levels of operating pressure (1.5-1-0.5) bar and two cultivars of cucumber crop (Omiga and Abu Zagheib).

The experiment was designed according to a randomized complete block design (RCBD the difference among means of treatments was tested using Duncan's multiple range test at a level of 0.01.

, The results showed that when evaluating the drip irrigation system, the pressure of (1.5) bar was significantly superior in infiltrating water and the area of wetness.

And the regularity of field emission, the values of these characteristics reached 9.62 L/h and 23.40 cm2 and the pressure (0.5) bar was superior to the regularity of field emission, reaching 98.68% .

The GR was superior to the wetting area and amounted to 22.98 cm2, the results of the interaction between 1.5 bar pressure and the spiral emitter showed a superiority in the dripping drainage and it amounted to 14.7 liters / hour and in the field emission regularity the pressure exceeded 0.5 bar and the T-Tape and the droplet was 99.

In the case of wetness area, the pressure exceeded 1.5 bar and the droplet GR reached 24.88 cm2 by 28% .

The results of the effect of pressure and emitters showed the superiority of pressure of 1 bar and emitter GR in the characteristics of number of fruits and number of leaves in Omiga cultivar.
