Abstract

Geostatistical techniques were used to characterize the spatial relationship between HORDEUM SPONTANEUM and CARDARIA DRABA seedling and seed bank over the course of one growing season (2004-2005) in three SAFFRON fields, located in Southern Khorasan, Iran. The density and spatial distribution of weeds varied widely with fields. The emergence percentage was higher for CARDARIA DRABA than for H spontaneum in all fields. Semivariograms showed spatial autocorrelation in seed bank and seedling populations of H spontaneum and C. draba in all fields. Cross-semivariograms showed moderate to strong (63.3 to 94.7%) and strong spatial continuity (78.4 to 95.4 %.) between seed bank and seedling population densities of Hspontaneum and C. draba, respectively. Grey-scale field maps of C. draba seed banks corresponded visually to maps of seedling populations and could have been used to target control efforts, but visual correspondence between H spontaneum seed bank and seedling maps was poor. Seed bank and seedling mapping may be useful for site-specific management, but additional information is needed to understand variation in the relationships between these two populations over time and space.
