Abstract:

Experiments were conducted to determine the possible allelopathic effects of jatropha (Jatropha curcas) on french bean (Phaseolus vulgaris L.) and brinjal (Solanum melongena). In one experiment, aqueous extract of jatropha leaf 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. In another experiments aqueous extract of jatropha leaf at 5%, 10%, 15% and 20% (W/V) concentrations were applied into soil to determine the allelopathic activity of jatropha on growth and development of French and brinjal. Plant growth of French bean in terms of plant height, leaf number, leaf area, root volume, shoot and root dry weights were reduced significantly by aqueous extract, particularly at higher concentrations. Relative leaf water content, total leaf chlorophyll content and leaf N P K content of French bean were also reduced by the aqueous extract. Moreover, pronounced negative allelopathic effects of jatropha on yield and different yield attributing parameters of French bean were recorded. However, no significant growth and yield reduction were recorded in brinjal with extract of jatropha leaf. From this investigation, it may be suggested that brinjal may be grown as an intercrop with jatropha.
