Effect of aqueous leaf extract of Moringa oleifera on germination and seedling growth of groundnut and cowpea:- Ugwa, Divine O.
ABSTRACT
The effect of the aqueous leaf extract of Moring@
oleifera on the germination and seedling growth of groundnut and cowpea was
investigated. five treatment levels having different concentration of extracts
(undiluted, 1: 1, 1 :2.5, 1.50) and control were used. Both laboratory and
field (pot) experiment were conducted in completely randomized design (CRD)
with three replications. The control treatment was only distilled water. The
result showed that the rate of germination of groundnut decreased with the
increase in aqueous extract concentration. The extract stimulated the growth of
groundnut at all treatment levels but has no significant effect on its dry
weight. The study revealed that aqueous leaf extract of Moringa oleifera
inhibited the germination of cowpea and as the concentration of extract increases,
it decreases the height and dry weight of the seedlings. This study therefore
suggests that allelochemicals released from the leaf part of Moringa oleifera
inhibited the germination of groundnut and cowpea while it stimulated the
height of groundnut but has no significant effect on its dry weight. It was
also observed that the aqueous leaf extract of M. oleifera inhibited the height
and dry weight of cowpea. This result therefore suggests that allelochemicals
may contribute to the allelopathic effect caused by moringa leaves.
