Allelopathic effects of thorn apple (datura stramonium l.) Residues on germination and early seedling growth of sugar beans (phaseolus vulgaris).

Abstract

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.
