Abstract:

Experiments were carried out to determine the possible allelopathic effects of jatropha (Jatropha curcas) on chilli (Capsicum annum) and green gram (Vigna radiata). Aqueous extract of jatropha leaf at 5%, 10%, 15% and 20% (W/V) concentrations were bio-assayed against germination and seedling growth of chilli and green gram. In both crops, germination percentage, germination index, plumule and radicle length, fresh and dry weight of plumule and radicle were appreciably reduced by aqueous extract of jatropha leaf in a concentration dependent manner. However, germination of green gram seed was found to be more sensitive to jatropha leaf extract. In one pot culture 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 chilli and green gram. Plant growth of green gram 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 chlorophyll content and leaf N P K content of green gram were also reduced by the aqueous extract. Similar type of inhibitory effect of jatropha was recorded in chilli at early vegetative growth stage. However, no significant growth and yield reduction were recorded in chilli with extract of jatropha leaf at maturity. From this investigation, it can be suggested that chilli may be grown as an intercrop with jatropha.
