THE APPLICATION OF SOME CHEMICAL SUBSTANCES AS PROMOTORS FOR ENHANING GROWTH, YIELD AND ITS SOME NUTRITIONAL VALUES OF OKRA PLANT (Hibiscus esculentus, L.)

Two field experiments were conducted out during the two successive
seasons of 2002 and 2003 at the experimental station of National Research Centre
at Shalakan to study the effect of some chemical substances, i e. GA, 1AA and urea as
a promotion materials by two methods of the applications (seeds soaking and plant
foliar application) on the growth, yield and its some physical and chemical
constituents. The important obtained results could be summarized as following
- in spite of the no significant effect of the application method of GA, lAA and urea on
some vegetative growth characters, but it could be concluded' that, the folrar
spraying (3 times by 10 days interval) gained the best okra plant growth. Moreover,
the using urea caused the best results, followed in descending order by using GA,
but the poorest plant growth was obtained by lAA.
- The total pods yield of okra plants recorded its higher no significant values by the
application of urea and/or GA if compared by the using of lAA.
There are no great effect of the application method of the studied chemical
substances on the total pods yield and its components
- Using GA, lAA and urea as seeds soaking andfor foliar application for okra plant
had no significant effect on N, P, K, Fe, Mn, Zn, Cu and total protein Generally,
using GA andlor 1AA gave the better nutritional value if compared to urea
appHcahon.
_ The interaction within using GA, lAA and urea as two methods of application, i.e.
seeds soaking or vegetative foliar spraying resulted no significant effect on ckra
plant growth, pods yield and its some physical and chemical propertied.
