Abstract:
Present nursery-based investigation was carried out to study the allelopathic effects of Acacia nilotica (L.) on vegetable crop (Trigonella foenumgraecum L. Acacia nilotica (L.) leaf leachate was prepared by soaking the dry leaves in tap water for 24hours in a ratio of 1:10 weight by volume. The prepared leachate was diluted to three different concentrations i.e. 25, 50 and 75 per cent by adding tap water accordingly, thus there were five treatments of leachates (control, 25, 50, 75 and 100% concentration). On germination paper, germination trial results revealed that the increasing concentration of the leaf leachates had inhibitory effect on germination parameters, plumule and radicle length intest crop. In green house condition, similar result was revealed with respect to germination parameters. The leaf leachates had both stimulatory and inhibitory effect on growth (shoot and root height) though significantly and non-significantly in fenugreek respectively. The yield (fresh and dry weight) was affected by different concentration of leaf leachate. As compared to control, inhibitory effect was observed for fresh weight and dry weight. However, the analysis of soil i.e. pH, EC, N, P, K, OC reported that Acacia nilotica (L.) leaf leachate had improved the status of soil. From this we can predict that Acacia nilotica (L.) might possess allelochemicals that causes both suppressive and stimulatory ability where in fenugreek was negatively affected by higher concentration. The nursery study indicated that the effect was proportional to the concentrations of the extracts so that higher concentration has a stronger inhibitory or stimulatory effect.
