The present study “ALLELOPATHIC INTERACTION OF WILD ONION (Asphodelus
tenuifolius Cav.) ON GERMINATION AND GROWTH OF SORGHUM (Sorghum bicolor L.)
AND MAIZE (Zea mays L.)” in Dayalbagh was attempted to explore the effect of Asphodelus
tenuifolius Cav.. In the present investigation we observed that the shoot extract and seed extract
of Asphodelus tenuifolius Cav. shows the inhibitory effect on germination of the test crops,
1- maize and 2- Sorghum.
Effect on Zea mays L. :-
The results revealed that different concentrations of Asphodelus tenuifolius Cav.shoot extract and
seed extract both caused significant inhibitory effect on germination and growth behavior of
Maize (Zea mays L.) seedlings. Maximum germination and growth occurred in control. Some
times lower concentration ie. 25% shows significant growth in shoot length and root length.
Similiarly the fresh weight and dry weight is also reduced by the inhibitory effect of Asphodelus
tenuifolius Cav.shoot extract and root extract.
Effect on Sorghum bicolor :-
It has been observed in present investigation that Sorghum bicolor L. also shows Similiar results
. The different concentrations of Asphodelus tenuifolius Cav. shoot extract and seed extract both
caused significant inhibitory effect on germination and growth behavior of Sorghum bicolor L.
seedlings. Maximum germination and growth occurred in control. Sometimes lower
concentration i.e. 25% shows significant growth in shoot length and root length.
Fresh weight and dry weight found more in control and 25% shoot extract of Asphodelus
tenuifolius L. than other concentrations.
The results demonstrates the allelopathic potential of the weed Asphodelus tenuifolius Cav. and
shows the inhibitory effect on the germination, shoot length, root length, fresh weight and dry
weight of Zea mays L. and Sorghum bicolor L.
It has been concluded that selected weed for the experiment i.e., Asphodelus tenuifolius Cav.
may affect the germination and growth behavior in inhibitory ways. The results highlight that
plant parts have inhibitory effect on crops due to the effect of allelochemicals which are present
in the dried and aqueous extract of the plant parts.
