Jointed goatgrass is an overwintering plant from the Poaceae family. It is used as a gene donor for winter wheat in different breeding programs. Nevertheless, in some countries and in Bulgaria as well it has turned into a big issue as a weed in the winter wheat. The plants are resistant to most of the herbicidal substances registered for weed management in wheat. Therefore, different approach for control has to be performed. One of the options is to apply “weed seed burial method” - turning over the arable layer trough plowing. A pot experiment for studding the germination depth and
development of the jointed goatgrass was performed. The depths of placing the weed’s seeds from 0 to 14 cm were studied. The period of emergence from each sowing depth, number and percent of germinated plants, total plant length, aboveground and root length, total plant weight, aboveground and root weight were evaluated. With increasing the depth, a delay of the germination and decreasing of the weed’s biomass development was recorded. Plants sown on 12 and 14 cm did not emerge.
