For the purpose of accomplishing optimal growth, scavenging (antioxidant) activity, and production of cabbage; an experiment was carried out one of the fields of college of Agricultural Engineering Sciences - University of Baghdad during fall season 2019 to evaluate the influence of foliar spraying of cobalamin and glutathione (GSH) and their interactions on cabbage plant. The experiment designed according to factorial RCBD with 3 replicates. The first factor is spraying cobalamin in three concentrations (0, 50, 100 mg.L-1) which symbolized (B0, B1, B2). Foliar application with three doses of GSH (0, 50, 100 mg.L-1) represented the second factor which symbolized (GS0, GS1, GS2).
The findings demonstrated that the individual factors were statistically significant in most of the study traits. (B2) was effective in increasing plant leaf area (333dm2), chlorophyll conc. in leaves (131.4 mg.100-1g f.w.), rolled leaves number (39.78), head weight (1600g) carbohydrates (heads) (4.211%) and scavenging activity (heads) (90.78%), Even more; (GS2) showed superiority in the stated traits (323.1 dm2, 132.1mg.100-1g f.w.,40.67 ,1728 g, 4.389%, 93.33%) respectively. The interaction between the two mentioned factors appeared to be statistically less significant than the sole factors. However; B2GS2 exhibited superiority in plant leaf area (362.0 dm2), head weight (1967 g), and carbohydrates percent (heads) (4.933%).
