| Abstract | ||
| The experiment was conducted in Kalar horticulture station / Sulaimania province in growing season 2006-2007 in a soil brought from one of the regional fields to determine the influence of interaction between the increasing concentrations of growth regulator (GA3) Which is (0, 25, 50, 75, 100) ppm and two level of the NPK fertilizers 18- 18- 18 is 40and 80 Kg/d this equals (0.32 , 0.64gm/4kg pot) in some growth characteristics of wheat. The experiment was applied through Completely Randomized Design. Results showed the increase in the value of the studied characteristics with the increase in the concentrations of (GA3) and the level of the NPK fertilizer.The influence of the interaction between concentration (75) ppm with the level of (80) Kg/d was positive giving the highest values of the studied characteristics. These characteristics dry weight, leaf area, absolute growth rate, relative growth rate, total chlorophyll content and soluble carbohydrate. | ||
