Abstract

In order to study the effects of amount and timing of NITROGEN APPLICATION and weed density on WILD MUSTARD (Sinapis arvensis) SEED PRODUCTION in WINTER WHEAT, an experiment was conducted in 2001 at Research Farm of College of Agriculture, Ferdowsi University of Mashhad. A Split plot design with three replications were used with factorial combination of weed density (0, 8, 16, and 32 plant/m2) and nitrogen (low=100, optimum= 150, and high= 225 kg/ha) as main plots. The sub plot factor included nitrogen splitting pattern (P1=1/3 at planting time+2/3 at tillering, P2= 1/3 at planting time + 1/3 at tillering + 1/3 at shooting). According to the results, WILD MUSTARD SEED PRODUCTION increased with increasing WILD MUSTARD density and nitrogen rates, due to high WILD MUSTARD biomass production. SEED PRODUCTION of WILD MUSTARD was 161, 311, and 488 million/ha in low, optimum and high nitrogen rates, respectively. In the other hand, density and nitrogen rates had a significant effect on WILD MUSTARD FECUNDITY: However, nitrogen splitting pattern showed no significant effect on WILD MUSTARD SEED PRODUCTION.
