ABSTRACT: The present work analyzed the yield, water utilize efficiency and water
productivity for carrot Crop under climate
change effects. In this research, river water was used with irrigation ratios
with drain water to irrigate the carrots (Daucus carota L.) crop during the winter growing season 2021-2022
in free field and utilizing furrow irrigation method with calculation the water
use efficiency and water productivity to three sites. The study was conducted in
the three sites in the Babil province in Town of Sadat-AlHindya reached 80 km
from Baghdad city. Site 1
was used 33% drain water and 67% river water while site 2 was used 83% drain water and 17% river water
but the site 3 was used 100% river water. The reduction of yield in site 1 was
17.3% and in site 2 was 75%. The reducing of WUE in site 1 was 23% and in site
2 was 77%. The decrease of WP
in site 1 was 22.98% and in site 2 was 82.28%. The value of water stress
coefficient (Ks) because irrigation by water salanity and soil salanty was
0.83, 0.78
and 0.92 in site 1,site 2 and site 3, respectively, water salanity and soil salanty reduction in
productivity by 9%, 14% and
7% in production of site 1, site 2
and site 3, respectively in every irrigating.
