Effieciency of Narra Bark Extract as Herbicides

	Project title: Effieciency of Narra Bark Extract as Herbicides
Difficulty level:	High school
Main link:	None

Hypothesis:

1. The plants in the Experimental group will eventually die.
2. There will be a great differences in terms of color in the Experimental Group.

Materials:

12 Monggo plant growing on my backyard. 9 for Experimental Group 3 for the Control
Different concentration of Narra Bark Extract (what ive used in my previous project)
750 ml. of water
214g Narra Bark
512g Narra Bark
2146g Narra Bark

The Procedure:

For the Decoction
boil 3 750 ml. of water with the Narra Bark

Monggo Plant
Experimental Group:
Water the plants daily around 4:00 -5:00 PM with 100 ml. of the decoction
(note: 3 plants will be used for every decoction)

Control Group
Water the plants daily around 4:00-5:00 PM with 100 ml. of Tap Water

Observe for 2 weeks

Results:

During the Invstigation Proper, I have recorded some changes happened. Eventually the Experimental Group die in different days. As my conclusion, the stronger the decoction is, the lesser the Plant will live.
