Abstract

The allelopathic effects of various concentrations (0 (as control), 5 %, 10 %, 20 % and 40%) of berseem clover shoot extracts were assayed on germination and radicle growth of four weed species ( Amaranthus hybridus, Amaranthus albus, solanum nigrum and chenopodium album) as completely randomized factorial with 3 replications. The effect of aqueous extract concentration of berseem clover on the mean germination time, radicle length and the equally germination was significant. S. nigrum had the highest germination percentage, the longest mean germination time, the highest radicle length and the lowest equally germination. A. hybridus had the lowest germination percentage, the mean germination time and A. albus had the highest equally germination. In total S. nigrum was the most resistant species and A. hybridus was the most susceptible species to aqueous extract of berseem clover.
