Abstract
This experiment was conducted at the Abooreihan campus in the growing season of 2005-2006. Tests were done in split plots with four replications. 3 wheat cultivars were tested in the main plots; Shiraz, Pishtaz and the newly introduced cultivar M79. Herbicide applications were tested in subplots; herbicide treatments of 2, 4-D applied at different times relating to growth stages of wheat; a control (without herbicide), at last tillering, at stem elongation, at booting and flag leaf sheath opening; Zadoks codes 27, 32, 40 and 47, respectively. Analysis of variance showed that between the different treatments there was significant difference for biomass, grain yield, 1000seed weight, number of fertile spikelet in each cluster and number of fertile tillers. Analysis of variance showed no significant difference between cultivars for biological yield, grain yield, 1000-seed weight, number of seeds per spikelet, number of fertile and infertile spikelet in each cluster and number of fertile and infertile tillers. Herbicide treatment at stages of tillering, stem elongation, booting and flag leaf sheath opening in comparison with the control treatment recorded reduced weight of weeds Fumaria vailanrii Loisel and number of weeds. Numbers of Sinapis arvensis weeds showed no significant differences between treatments for dry weight weed last tillering but significant difference was recorded at the booting stage.
