Allelopathic Effects of Thorn Apple (Datura Stramonium L.) Residues on Germination and Early Seedling Growth of Sugar Beans (Phaseolus Vulgaris)
Abstract
A Laboratory experiment was carried out to determine the allelopathic effects of Thorn apple
(Datura stramonium) residues on Sugar bean germination and early growth rate. Datura
stramonium residues are problematic to crops, as they inhibit seed germination and seedling
elongation when incorporated into the soil during land preparation. The substances released by
Datura stramonium act as germination or growth inhibitors. The experiment was carried out to
determine the allelopathic effects of Datura stramonium residues on germination of bean seed and
early seedling growth of the roots and shoots. Complete Randomized Design (CRD) with six
treatments and three replications was used during the research. Concentrations of 0% as the
control, 10%, 30%, 50%, 70% and 100% of Datura stramonium residue solution were used to
carry out an investigation of the allelopathic effects of Datura stramonium residues on the
germination of bean seeds. There was significant reduction (P<0.05) in root and shoot length which
was observed in higher concentrations of 100% Datura stramonium residue solution. It was
established that the allelopathic effects of Datura stramonium residues was concentration
dependent. The inhibitory effects significantly (P<0.05) increased proportionally as the
concentration of both extracts increased from 0% to 100%. This research concluded that Datura
stramonium residues have allelopathic effects on germination, root and shoot development of bean
seeds. It can be recommended that sugar beans farmers should get rid of the thorn apple weed and
its residues before land preparation so as to avoid poor seed germination and early seedling growth
