Spreading hedgeparsley is a weed of wheat fields which thier seed bank is increasing in Kermanshah province. The aim of this study was to investigate the effect of time, burial depth, and seed shape in the field. This study was conducted as a factorial experiment in a completely randomized design with 3 replications. Both hairy and non-hairy forms of spreading hedgeparsley seeds were placed in different depths of storage (control), zero (soil surface), 5, 10, 20, and 40 cm of soil, and then seeds digged out from soil at 3, 6, 9, and 12 months burial time. The results showed that the effect of time, burial depth, and seed shape treatments on germination was significant in the field. The highest percentage of spreading hedgeparsley seed germination was observed in the first 3 months after burial. In general, the percentage of seed germination decreased by time. At a depth of 5 cm in the soil due to the favorable environmental conditions such as temperature, light and oxygen, the highest germination percentage was observed. Seed germination percentage decreased with increasing depth. The percentage of germination of spreading hedgeparsley seeds was higher than that of spinyseeds due to the level of contact of seeds with light, temperature and humidity.
