Abstract
Allelopathy is a chemical interaction between plants wherein certain
species release biochemicals, known as allelochemicals, that influence the
growth, survival, and metabolism of neighboring plants. This phenomenon is
especially critical in understanding the ecological and agricultural impact of
invasive species. The present study investigates and compares the allelopathic
effects of two invasive plants—Lantana camara and Cassia tora—on the
germination, morphological development, survival, and biochemical responses of
Pisum sativum (pea), a vital leguminous crop. Aqueous leaf extracts of varying
concentrations (5%, 10%, 15%, 20%) were applied in controlled experiments, and
key parameters such as germination rate, root/shoot length, chlorophyll
content, protein levels, proline accumulation, and antioxidant enzyme activity
were measured. Results indicated that both species exert significant inhibitory
effects, with Lantana camara demonstrating stronger allelopathic influence than
Cassia tora, particularly in reducing biomass and elevating stress markers like
MDA and catalase activity. The study confirms a dose-dependent decline in pea
plant health and survival across treatments. These findings carry important implications
for sustainable agriculture, as they highlight the need for strategic weed
management, crop rotation planning, and further research into soil interaction
dynamics. By understanding these plant-plant chemical interactions,
agricultural systems can better mitigate productivity loss in pulse-growing
regions.
