AbstractThis study is conducted at the greenhouse of the experimental research station
, College of Agriculture University of AL-Muthana . The experiment includes a
foliar sprays to Okra plants with fifteen treatments , i-e . F1 control . F2
liquorice roots extract at 3.5 gm L 1-F3 Prosolat 1.5 gmL ، 1-F4 Terrasorb .at
2mlL ، 1-F5 Garlic extract at 2.5 gmL 1- and the interaction between them . Theexperiment also includes the foliar spray with zinc at 0 , 3.5 , and 4.5 gmL ) 1-
Zn1 , Zn2 , Zn3 ) ZnSO7 . 4H2O was used as source of zinc element.
The foliar sprays with the foliar feeding is done three times with in 30 ، days
between each of them while the foliar sprays with zinc is done thrice , 15 days
between each of them . RCBD was adopted with three replicates using LSD at
0.05 to compare between the treatments .
The experimental results have shown that the highest vegetative growth values
is found when the plants is sprayed with liquorice root extract which also
significantly is superior that the other treatments in plant height , fresh and dry
weight of leaves per plant , fresh and dry weight of roots , fresh and dry weight
of shoots , the number of branches and leaves ( 41.81 cm , 20.4 gmplant ، 1-
3.81gmplant 14.09 ، 1- gmplant 3,94 ، 1- gmplant 67.32 ، 1- gmplant ، 1-
13.15gmplant 10.4 ، 1-branch plant ، 1- and 30.36 leaves plant 1- respectively ,
while no significant differences between F2 and F5 in the length of roots .
-1 Zn significantly increase the parameters
studied in their experiment over the others treatments
