Keywords: Humic acid, EM1 fertilizers, Cultivar, Cucumber.


This experiment was conducted in the plastic house at the vegetable research farm of Directorate of
Agricultural Extension and Scientific Research of Dohuk, Kurdistan region/ Iraq, during the growing
Seasons of 2018-2019, to investigate the effects of Humic acid, (0.8 g.l-1
and 1.6 g.l-1
) and EM1 (3 ml.l-1
) in addition to the Control on growth and yield of two Cucumber cultivars (Falcon star and Sayfi F1).
The results shows that Falcon star was superior over to Sayfi F1 in plant length and chlorophyll in leaves in
fall season (2.91cm and 51.76SPAD), while Sayfi Fi overcome to Falcon star on chlorophyll in leaves, fruit
diameter in spring season (47.40SPAD and 2.90cm). No significant effect of fertilizers had been seen in
vegetative characters. But the yield characters had significant effects, the 3ml.l-1 of EM had higher value of
Fruit weight 111.71g in spring season, while 6ml.l-1
of EM had higher (Plant yield 5.36Kg and Total yield
139.51 ton.ha-1
) in fall season. Control treatment had higher fruit length and diameter (17.01cm and 2.91cm)
in spring season.
