The present study was conducted to investigate the allelopathic effects of Parthenium hysterophorus weed on seed germination and early growth stages of peanut and soybean. Leaf, stem, and root aqueous extracts of Parthenium at 0, 2, 4, 6, 8, and 10 g/1000 ml concentrations were applied to determine their effect on both crops seed germination and early growth stages under laboratory conditions. Two runs of laboratory-based experiment with factorial Complete Randomized Design (CRD) with three replications was used to arrange treatments accordingly. The result of study revealed that peanut seed germination only significantly (P ≤ 0.05) responded to the parthenium stem and root extracts; where on average 2 and 4 seeds were germinated per petridishes, respectively under high concentration treatment of 10 g/1000 ml. whereas, soybean seed germination was significantly responded to all the parthenium plant parts extracts. However, the serious effects have been well observed under the treatments of 10 g/1000 ml stem extracts and 8 g/1000 ml root extracts, where no germination of soybean seed was recorded. Similarly, shoot length was seriously inhibited by the stem extracts for peanut and leaf extracts for soybean, accounting 5.67 and 1 cm, respectively. However, the least average root length of 3.33 cm for peanut and 0.67 cm for soybean has been noticed with the leaf aqueous extracts under 10 g/1000 ml. The study also revealed that the phytotoxicity of parthenium plant parts increase with the increasing concentrations of extracts. Phytotoxicity of parthenium has been more pronounced over soybean germination and early growth stages than peanut.
