The impact of pesticide use in the fight against bush associated with soft varieties of wheat, Triticum aestivum L.And the percentage of protein in the grain

Abstract

Two field experiments were carried out during the winter seasons 2004-2005 and 2005-2006 in the experimental field of the Directorate of Agriculture of Diyala (Baquba Arboretum) located within latitude 20 33 North and longitude 44 24 East, at an altitude of 34.1 m above sea level. Five varieties of soft wheat (Abu Ghraib, Iba 99, Sham 6, Al-Fateh, Iba 95) to the Chevalier pesticide used to control the annual thin and broadleaf bushes accompanying the crop, and to determine the most responsive variety or cultivars first (the cultivar or cultivars that competed with the weeds by the action of the pesticide compared to other cultivars ), then using Chevalier pesticide with bentazone pesticide to control different types of weeds accompanying wheat cultivars that achieved response to Chevalier pesticide in the first experiment, and the extent of the effect on the percentage of inhibition by dry weight of weeds and its implications on the percentage of protein in the grain. The two experiments were carried out according to the split-plot design with three replications.
