Abstract
An experiment was conducted in order to determine the allelopathic effects of Trianthima portulacastrum L. on the seed germination, seedling growth and chlorophyll content of sesame (Sesamum indicum L.). Greenhouse experiment was carried out as RCBD (Randomized complete block design) with four replications. Treatments included 0, 1, 2, 3 and 4% (W/W) residues of whole plant of T. portulacastrum with normal field soil. Results showed that the low concentrations of T. portulacastrum had no significant effect on the germination percentage, seedling length, dry weight, total chlorophyll contents of test crop. However, treatments with higher concentrations had negative effects on germination, growth and seedling dry weight of sesame
