Abstract
Two field experlments were conducted during 1997/1998 and 1998/1999, at the Experimental Station of the National Research Centre at Shalakan. Kalubia Governorate to study the physiological response of wheal plants to different concentration of atonik ( 0 , 2C ,40 and 60 mgll ) and Pix ( 0 . 50 , 100 and 200 mgll ) as well as their interaction on vegetative growth, yield and its components as well as the content of crude protein and total carbohydrate in produced grains. The data indicated that spraying atonik with different concentrations at all stages led to significant increases in plant height, number of tiller, number of spikes. blades area, leaf area index, dry weight of plant. spike weight and length. 1000· grains weight. grain and straw yield per plant and per fed. VoJhile , spraying pix led to signifICant decreases plant height, both number of tiller, and spikes/plant. leaf area, leaf area index and carbohydrate percentage in grains,
Spraying wheat planls with atonik at 60 mgJ1 or pix at 50 mg/l caused the highest values in most of growth characters. Spraying plant with 60 mgllalonik and pix at 100 and 200 mglt attained sfgnificant increases in economic yield and ils components as compared with other treatments. Application of etonik treatments in general had a positive effect in most cases on protein and carbohydrate percentage. atonik at 40 and 60 mgll was more effective. while, the highest value was obtained at 100 mgll pix on crude protein content and 50 mgIJ pix on total carbohydrate content.
Interaction between atonik at 40 and 60 mgll and pix at 50 and 100 mgll gave the highest values of growth Characters. Application atonik at 60 mgJI with pix at 200 mgll increased significantly yield and its components as compared with of her treatments, Interaction between atonik 60 mgIJ with pix at 100 mgll and atonik at 20 mgJI with pix at 200 mgll gave the highest values of crude protein and carbohydrate percentage in produced grains. respectively.
