The Influence of Foliar Sprays with Some Nutrient Solutions and Plant Extracts and Zinc on Vegetative Growth of Okra Plants (Abelmoschus esculuntus L).

Abstract

This study is conducted at the greenhouse of the experimental research station, College of Agriculture University of AL-Muthana . The experiment includes afoliar sprays to Okra plants with fifteen treatments , i-e . F1 control . F2liquorice roots extract at 3.5 gm L 1-F3 Prosolat 1.5 gmL ، 1-F4 Terrasorb .at2mlL ، 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 ، daysbetween each of them while the foliar sprays with zinc is done thrice , 15 daysbetween each of them . RCBD was adopted with three replicates using LSD at0.05 to compare between the treatments .The experimental results have shown that the highest vegetative growth valuesis found when the plants is sprayed with liquorice root extract which alsosignificantly is superior that the other treatments in plant height , fresh and dryweight of leaves per plant , fresh and dry weight of roots , fresh and dry weightof 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 parametersstudied in their experiment over the others treatments
