ABSTRACT The present study aimed to analyze the effect of different concentrations of aqueous extracts of Tephrosia purpurea, Ipomea carnea, Trianthema portulacastrum, and Tithonia diversifolia on Centella asiatica and Allium cepa, Solanum tuberosum and Calotropis gigantia on Mentha arvensis respectively. Extracts of 5%, 10%, 20% & 50% concentrations were prepared and fertigated by pot experiments. Results of this study showed that extracts of T.purpurea (50%), I. carnea (10% & 20%), T. portulacastrum (10%, 20%& 50%) and T. diversifolia (5% &10%) enhanced the growth of C. asiatica when compared to the control. Calotropis extract (15%) enhanced the growth of M. arvensis and lowest growth was recorded in onion peel extract (5%). T. diversifolia extract at lowest concentration (5%&10%) increased the leaf surface area (38.8±0.4cm2), petiole length (17.6±0.6cm) and fresh (120.6±2.0g) & dry weight (52.4±0.5g). Lower concentrations of T. purpurea (5% &10%) and higher concentrations of I. carnea (50%) inhibited the growth, number of leaf, leaf surface area (3.8±0.7cm2), petiole length (2.63±0.3cm) and fresh (10.8±1.7g) & dry weight (3.1±0.7g) in Centella asiatica and Calotropis extract (15% concentration) on M. arvensis increased the number of leaves (57±3), leaf surface area (12.7±0.9), shoot length (39±2 cm2) and total fresh weight (170±1.5g) when compared to the control. Significant reduction existed in all the parameters at higher concentrations of the extracts used. |
