Abstract: 

In order to investigate rye allelopathy on weeds' density and biomass, an experiment was conducted at research farm of Tehran University (Karaj Campus) in 2004-2005 growing season. A RCB design with 3 replications was used. Treatments included: cut rye, spread as mulch, rye cutting followed by gathering the residue, none-cut rye, glyphosate application to provide stress condition, weed infested and weed free checks. Results showed that rye had a significant effect on weeds' density and biomass. It controlled pigweed (Amaranthus retrojlexus), knotweed (Polygonum aviclllare), common fumitory (Fumaria officinalis), lambsquarters (Chenopodium album) as well as saltwort (Salsola. spp.). The treatments had no significant difference among each other but were significantly different from weed infested check. However, there were differences observed among treatments in control of field bindweed (Convolvulus arvensis). In a second experiment, the effect of rye extract on soybean (Glycine max) germination in a CR design with 3 replicates was assessed. Plant extracts of 0%, 50%, 75% and 100 %, were prepared. The effect of treatments on germination parameters showed that high concentration of plant extract had a significant decreasing effect on the germination traits.
