Abstract

In order to evaluate competition of wheat with wild mustard (Sinapis arvensis L. ) and wild oat (Avena ludoviciana Durieu) to Nitrogen and herbicide, a field experiment was conducted as split plots in a randomized complete block design with four replications at Agricultural Sciences and Natural Resources University of Khuzestan. Nitrogen fertilizer included in five levels of 0, 45, 90, 180 and 330 kg ha-1 of urea was considered as main plots and herbicide dose of Othello OD (mesosulfuron methyl + iodosulfuron methyl sodium + diflufenican + mefenpyr-diethyl) in six levels of (0, 20, 40, 60, 80 and 100 % the recommended dose (1. 6 L ha-1 the recommended dose)) was considered as sub plots. The results showed that weed and wheat biomass response to herbicide doses were followed by response and sigmoid dosage models, which with increasing of Nitrogen fertilizer application, those models were developed. Based on the prediction of the combined model, weed boimass with half of the recommend dose of Othello OD herbicide, and by applying 0, 45, 90, 180, 230 and 330 kg ha-1 of Nitrogen was estimated 105/69, 182/71, 212/61, 128/13, 60/70 and 10/60 g m-2, respectively. Also, 750 g m-2 of wheat biomass, was recorded by 265 kg ha-1 of Nitrogen fertilizer with 0/80 L ha-1 herbicide dose, and/or by applying of 330 kg ha-1 of Nitrogen fertilizer and 0/72 L ha-1 herbicide dose.
