The oil cake obtained from seeds of Ailanthus excelsa was studied against Pennisetum glaucum and Vigna radiata for its bio-fertilizer capability. The inhibition of seed germination increased with increase in concentration of seeds oil cake. The aquatic extracts of 2, 4, 6, 8 g and control were evaluated in vitro. The oil cake showed the allelopathic properties against both the plants. The inhibition of seed germination increased and fresh dry weight decreased by increase in concentration of seeds oil cake. The maximum seed germination was 80 and 70% in control and minimum 20 and 30% in 8 g in V. radiata and P. glaucum respectively. Similarly, maximum growth was observed in control 3.625 and 3.630 cm, 1.06 and 1.08 cm in 2 g and minimum 0.126 and 0.128 cm in V. radiata and P. glaucum, respectively. The oil cake may find applications as feed or fodder after testing its toxicity and safety parameters. It can be used to control Phalaris minor like weeds which are resistant to weedicides.
