| Abstract | ||
| Very strong evidence was obtained from this observation of competition between two wild plant species (Imperata cylindrica and Cynodon dactylon), those two species living at semi-natural pasture, in competition and coexisting conditions with reduced densities. The two species have different life-forms, therefore effect of mowing activities was in benefit of C. dactylon. as creeping plant which suffer less of mowing process. The plowing disturbance plot was invaded by only species that had already exist at the plot (C. dactylon and Alhagi maurorum). There was no I. cylindrica, recover, in spite of this species was existing at the same pasture. Concluding that there is (might be) chemical (allelopathic) substances produced by C. dactylon, inhabited germination seeds of I. cylindrical | ||
