Nevertheless, there are several methods suggested which could be used to reduce possible yield losses caused by this weed. Nitrogen treatments of Nicotiana tabacum plants reduced the time for, and enhanced uniformity of, seed germination (Thomas and Raper, 1979). Paris, France: COLUMA/EWRS, 1:173-182. There is great variation in yield loss according to the type of crop, the season and the timing of the infestation. It seems that delaying sowing could affect weed infestation by enhancing weed germination prior to crop sowing through the establishment of a false or stale seedbed (Buhler, 2002). convolvulus occurs on a wide range of soil types (Hume et al., 1983), but according to Paatela and Erviö (1971) it is less common on peaty soils.
