Abstract

In order to evaluate WILD MUSTARD potential seed production in monoculture and reproductive response of this weed to WHEAT seed rate and nitrogen fertilizer, an experiment was conducted in 2000-2001 at Agricultural Research Station Ferdowsi-of Mashhad, University, Iran. The experimental design was a factorial split-plot with three replications. The experiment had three factors: Three levels of WHEAT seed rate (175, 215 and 225 kg/ha), two levels of nitrogen rate at optimum and upper optimum rate of WHEAT (150, and 225 kg N/ha), and four levels of WILD MUSTARD density (0, low, medium, and high). Increasing seeding rates of WHEAT, from 175 to 215, and 255 kg/ha, reduced WILD MUSTARD seed production per plant by 62, 66 and 71%, respectively, compared to its monoculture yield. Increasing in WHEAT seed rate from 175 to 255 kg/ha, in optimum rate of nitrogen, reduced WILD MUSTARD seed production at high density by 40 %, while in upper optimum nitrogen rate, seed production was reduced only 11%. High seed production of WILD MUSTARD (21-941 million seed/ha) in the presence of WHEAT competition indicated that if weed management programs is neglected for one year, soil seed richness would be established for several years.
