Abstract
Bidens pilosa Linn belongs to the family Asteraceae. It is considered a weed in some tropical habitats; however, its allelopatthy potential has not been fully established. Therefore, this study aimed at investigating the allelopathic effects of B. pilosa on germination of soybean, maize, tomatoes and seedling growth of soybean. Allelopathic effects of B. pilosa leachate on soybean, maize, tomatoes germination and soybean seedling growth were assessed in the screen house. Germination percentage (%) for test crops was determined at 10 Days After Sowing (DAS); while Number of Leaves (NL), Plant Height (PH) (cm), Root Length (RL) (cm) and Dry Weight (DW) (g) were evaluated at 9 Weeks After Sowing (WAS). Experimental design used in the study was Completely Randomized Design. Data were analyzed using ANOVA. Means were separated and compared using Least Significant Difference (LSD) at 5% probability. The least germination (27.0 ± 0.3) was recorded for L1-Soybean, while L1-Maize gave the highest germination (60.0 ± 1.0) and L1-Tomatoes gave (37.0 ± 0.3). The L1 soybean seedling had the lowest NL, PH and DW values; while control had highest RL in soybean. Biden pilosa inhibited germination in all test crops. The leachate of Biden pilosa could be a potential bio-herbicide.
