Abstract

In order to investigate the effects of integrating chemical and mechanical weed management in corn, an experiment was conducted in agriculture and natural resources college of Darab, Fars province, in 2004 and 2005 years. The experiment was conducted based on randomized completely block design with 11 treatments and 3 replications. The treatments were the application of ATRAZINE plus ALACHLOR at 1+2.5 and 0.5+1.25 kg ai ha-1 used as broadcast and band application alone and in combination with rotary or SWEEP CULTIVATORs and mechanical weeding alone. In 2004, at 6 and 17 weeks after planting (WAP), maximum biomass reduction of redroot pigweed was observed for ATRAZINE plus ALACHLOR at 0.5+1.25 kg ha-1 with double SWEEP CULTIVATOR. At 6 WAP maximum biomass reduction of purslane was obtained for ATRAZINE plus ALACHLOR at 0.5+1.25 kg ha-1 with double SWEEP CULTIVATOR by 83٪. At 17 WAP uniform broadcasting of ATRAZINE plus ALACHLOR at 1+2.5 kg ha-1 reduced purslane biomass to 89٪. In 2005, at 17 WAP, minimum biomass reduction of redroot pigweed was obtained with band application of ATRAZINE plus ALACHLOR at 0.5+1.25 kg ha-1. At 6 WAP in uniform broadcasting of ATRAZINE plus ALACHLOR at 1+2.5 kg ha-1 reduced purslane biomass to 100٪. In 2004 and 2005 at 6 and 17 WAP, ATRAZINE plus ALACHLOR at 0.5+1.25 kg ha-1 with double SWEEP CULTIVATOR reduced johnsongrass biomass 83 to 91٪. Results of both years showed that all treatments increased CORN GRAIN YIELD as compared with the weedy check. Maximum CORN GRAIN YIELD was obtained with ATRAZINE plus ALACHLOR at 0.5+1.25 kg ha-1 with double ROTARY CULTIVATOR. The results emphasize benefits of integrating weed management as compared to chemical and mechanical weed control systems alone.
