Abstract
An experiment was carried out in the plastic house of Horticulture Department/college of Agriculture/ Duhok University on Cucumber plants during 2009 growing season to determine the effect of bread yeast and seaweed extracts Alga 600 and sea force 2 on growth, yield and its component on Cucumber C.V. shadi. The results showed that spraying bread yeast or seaweed extract resulted in positive significant difference in shoot characteristics and in all yield traits as compared to untreated treatment. The interaction between yeast and seaweed extract was significantly enhanced all detected traits. Since cucumber plant received 6 g.l-1 bread yeast and sprayed with a mixture of 0.33ml.l-1 Alga 600 +2.5 ml.l-1 Sea force 2 were characterized by the highest values of all shoot and yield characteristics.
