Evaluation of Efficiency Different Concentrations of SURAGE Herbicides on the Growth and Yield of Two Varieties of Wheat (Triticum aestivum L.) and Associated Weeds

Abstract

Abstract The experiment, was carried out during the 2021-2022 agricultural season in two locations, the first location in AlNamrood, district, 40 km south east of the city center, and the second location in Tal kaif district, 15 km north of the city center, with different soil textures, in to evaluate the efficiency of different concentrations of SURAGE and varieties in growth and wheat (Triticum aestivum L.) and associated weeds. The experiment include two factors, The first was two Varieties of wheat (Tal Afar 3 and Wafia) and the second factor was SURAGE herbicide with three concentrations (SURAGE -25, SURAGE R.C and SURAGE +25), control treatment was SURAGE -25 (25% less than the recommended concentration, 75% a.i. of the recommended concentration), SURAGE R.C. (100%, a.i. the recommended concentration), SURAGE +25 (more than the recommended concentration by 25%, a.i. 125% of the recommended concentration) in addition of control. The experiment application according factorial experiment system (split-plot) using RCBD and Duncan’s multiple range test was used to compare average the treatment. The most important results can be SURAGE R.C. and SURAGE + 25 have the lowest total weight of weeds with an efficiency rate of 61.83% and 58.8%, respectively in AlNamrood location, and treatment SURAGE + 25 in Tal kaif location efficiency rate of 39.53%. have treatment SURAGE R.C. the highest yield at Al-Nimrod and Tal kaif location was 60.83% and 51.04% for AlNamrood and Tal kaif location, respectively.
