Merr.] varieties JF - Notulae Scientia Biologicae JA - Not Sci Biol VL - 13 IS - 1 SE - Research articles DO - 10.15835/nsb13110876 UR - https://www.notulaebiologicae.ro/index.php/nsb/article/view/10876 SP - 10876 AB - <p style="text-align: justify;"><em>Datura stramonium</em> (L.) contains allelochemicals capable of affecting agro-morphological traits in plants. Thus, field experiment was carried out at Upper Niger River Basin Development Authority, Minna, Nigeria to examine the effects of different concentrations [25%, 50% and 100% and 0% (control)] of <em>D. stramonium</em> aqueous seed extracts on agro-morphological attributes of two soybean varieties (‘TG x 2018-5E’ and ‘TG x 2022-4E’), obtained from International Institute of Tropical Agriculture, Ibadan. Dry seeds of the soybean were pre-soaked in the <em>Datura</em> seed extracts for two hours before planting in a complete randomized block design (CRBD) with three replicates each. Data obtained were subjected to analysis of variance (ANOVA). At maturity, <em>D. stramonium</em> seed extracts significantly (P ≤ 0.05) increased plant height (38.37 cm) and length of petiole (2.93 cm) for ‘TG x 2018-5E’ at 100% concentration. Significantly highest plant height (29.20 cm) and number of branches (17.00) were enhanced in ‘TG x 2022-4E’ at 50% concentration. Both ‘TG x 2018-5E’ and ‘TG x 2022-4E’ leaf areas were significantly highest (23.11 cm<sup>2</sup> and 28.41 cm<sup>2</sup>, respectively) at 100% concentration. Yield attributes such as number of seeds per plant, weight of fresh and dry pods per plant for both ‘TG x 2018-5E’ (3.33, 1.60 and 1.32, respectively) and ‘TG x 2022-4E’ (3.00, 0.60 and 0.26, respectively) were significantly stimulated in 50% concentration while number of pods per plant was significantly highest for ‘TG x 2018-5E’ and ‘TG x 2022- 4E’ (3.33 and 3.00, respectively) in 100% concentration. On these premises higher concentrations (50% and 100%) of <em>D. stramonium</em> seed extracts support better morphological growth and yield characters in soybean varieties.</p> ER -
