Abstract

Two field trials of wheat (Triticum aesitivum var. Sids l) were carried out in two different sites in Salama Hegazy village in Bangar El-Sokkar region under optimum cultural practices. These fields were severely infested with grassy and broadleaf weeds. Nine herbicidal combinations were performed with or without atonik as a plant growth stimulator. The effects of herbicidal combinations with or without atonic on weeds; wheat grain yield and yield components; and grain quality were studied. The results indicated that most herbicidal combinations with atonik gave highly significant reduction of grassy weeds and clodinafop is a graminicide when combined with either new broadleaved herbicides (derby, harmony or metosulam) or with old broad leaf herbicides (Pyridate Fluroxypyr or bentazone) gave good results in controlling grassy and broadleaf weeds in Bangar El-Sokkar region. Regard to the number of spikes/m , and spikelets / spike, biological yield and grain yield, clodinafop combinations significantly increased wheat grain yield and its components. The data also revealed that the wheat quality characters (protein %, starch and total soluble sugar) were significantly improved in wheat grain especially in the presence of atonik stimulator.
