ABSTRACT

Allelopathic potential of the rice field weed, water primrose Ludwigia adscendens (L.) leaf,
stem and leaf+stem on germination, root and shoot length, seedling vigour and vigour index of
the greengram [Vigna radiate (L.), cv.KB-54], was investigated in the laboratory. The different
concentrations (e.g. 5, 10, 20, 40, 60, 80 and 100%) of the aqueous extract of leaf stem and
leaf+stem of the weed parts were applied separately on greengram seeds in petri dishes lined
with filter paper. The per cent of germination decreased from 4–32%, 2-23% and 7–36%, and
root length and shoot length of the greengram also decreased from 0.01-2.04 cm, 0.02-1.96 cm
and 0.07-2.08, and 0.818-1.575 cm, 0.785-1.567 and 0.83-1.64 cm for increased concentrations
of the weed leaf, stem and leaf+stem extracts over control, respectively. The seedling vigour
and vigour index of the greengram were decreased considerably from 13.32-237.6, 8.14-221.9
and 28.14-244.36, and 85.68-166.62, 80.65-164.44 and 90.21-171.92 with increased
concentrations of different parts of aqueous extract of the weed over control, respectively
