Abstract:
A experiment was conducted under laboratory condition to ascertain to find the effect of aqueous extract of jatropha leaf on germination and seedling growth of French bean and Brinjal. The experiment was laid out in completely randomized design having four treatments with three replications at Assam Agricultural University, Jorhat, Assam. Jatropha leaf extract at 5%, 10%, 15% and 20% (W/V) concentrations were bio-assayed against germination and seedling growth of french bean and brinjal. In both the crops, germination percentage, germination index, shoot and root length, fresh and dry weights of shoot and root were appreciably reduced by aqueous extract of jatropha leaf in a concentration dependent manner. However, germination of french bean seed was found to be more sensitive to jatropha leaf extract. From the recorded data of the present investigation, it was observed that reduction in germination percentage in french bean with 20% concentration of aqueous extract was 34.48% over control, whereas in brinjal, it was only 24.00%.
