The efficacy of some weed killers for the control of weeds associated with two kinds of wheat (Triticum aestivum L.)

Abstract

This survey was conducted during 2015–16 in the Tuz area i. e. far away about 110–120 kilometers from the Salah al-Din Province of Iraq. Using herbicide in strategic way will be effective from an agronomic view point to contain weeds. The purpose of the study was to notice out the effects of different types of herbicides on weed management and growth and grant components of two cultivars of wheat. The treatments included in the study were three herbicides (Atlanti WG @ 400 g/ha, chevalier @ 400 g/ha and mixture of Topeka 800 cm3/ha+Lintur WG 70% @ 120 g/ha) and two cultivars of wheat (Abu-Ghraib and Ebaa99). The randomized complete block design was used in this study with three replications. The results showed that the full number of weeds significantly reduced with all discussions of weed killers, thus reduced competition of weeds with the crop. The wheat cultivar Ebaa99 produced a significantly higher number of tillers per plant (13.42) and grain yield (675.85 kg/ha) comparisons to cultivate Abu-Ghraib. Either herbicides effect was positive, all towards the weeds associated as ratio control for herbicides; Atlantis and mixture (Topik+Lintur) and Chevalier 93.6, 98.2 and 98.5%, respectively, either in properties of the tiller number per plant and the number of grains per spike and grain yield did not differ significantly from free weed treatment either overlap recorded Ebaa 99 parents and all pesticides product was superior to Abu Ghraib for most of the qualities and special quotient.
