DOSE -DEPENDENT ALLEOPATHIC RESPONSES OF OKRA TO AQUEOUS LEAF EXTRACTS OF COMMON WEEDS

Abstract Allelopathy plays a significant role in crop–weed interactions and offers an eco-friendly alternative to chemical weed management. The present investigation evaluated the allelopathic effects of three weed species, Alternanthera sessilis, Synedrella nodiflora, and Sphagneticola trilobata, on seed germination and early growth of Abelmoschus esculentus (okra) under in vitro and in vivo conditions. Crude aqueous leaf extracts at 10%, 30%, and 50% concentrations were tested using a completely randomized design. The results revealed marked species- and concentration-dependent effects. Alternanthera sessilis significantly inhibited germination and root growth under in vitro conditions, especially at higher concentrations, while no significant effects were observed in vivo. Synedrella nodiflora caused significant inhibition of germination and root elongation in vitro, with one-way ANOVA confirming significant differences in root length (p = 0.0238), whereas in vivo treatments showed improved germination and seedling growth. Sphagneticola trilobata exhibited a hormetic response, while germination percentage varied significantly with concentration (p = 0.001). In vivo effects showed a positive trend but were not statistically significant (p > 0.05).The study concludes that allelopathic effects vary with experimental conditions and highlights the potential use of selected weeds in sustainable agriculture.
