Abstract

Because of the importance of weed control in corn inbred lines, this study was carried out based on a randomized complete block design with 10 treatments and 4 replications in Meshkindasht, Karaj, Iran. Two lines including Mo17 (male strile, CMS) as male parent and B73 as female paraent were used. Treatments were: nicosulfuroun (SC 4%), nicosulfuroun + (bromoxynil + MCPA (EC 40 %)), rimsolforun + nicosulfuroun (DF 75%), foramsulfuron (OD 22. 5%), 7 & 8) mesotrione + Smetolachlor + terbuthylazine (SE 53. 75%), weed infest control and hand weeding control. Results showed the significance (P < 0. 01) of the effect of herbicide treatments in reducing weed density and dry weight. The results of the percentage reduction in density and weeds dry weight and herbicide performance evaluation by the European scoring (EWRC) showed that the effectiveness of herbicides was good except for mesotrione-terbuthylazine-S-metolachlor herbicides. The highest corn grain yield was obtained from (nicosulfuroun + (bromoxynil + MCPA)) 400 + 40 g ai/ha and hand weeding with 4. 26 and 4. 03 ton/ha and the lowest grain yield were obtained from mesotrione-terbuthylazine-S-metolachlor and weed infest control with 2. 30 and 1. 11 respectively. Totally, for weed management in corn inbred lines, application of (nicosulfuroun + (bromoxynil + MCPA)) 400 + 40 g ai/ha, rimsolforun + nicosulfuroun 90 g ai/ha, foramsulfuron 337 g ai/ha and nicosulfuroun 80 g ai/ha are recommended. The herbicide applications did not have an adverse effect on seed germination of corn hybrid obtained from lines fertilization.
