| Abstract | ||
| A field experiment has been implemented in the research station of the department of field crops / College of Agriculture / Tikrit University in fall season of 2013. The objective of the study is to investigate the effect of two commercial weeds herbicides, Camix ec 560 at three concentrations 2,3 and 5 Lh-1 and Perfect at three concentrations 30,50 and 70 gmha, on the dent of the yellow corn hybrid Spanish Cardiz and the growth of associate weeds. The experiment has been applied according to the Randomized Complete Block Design method (R.C.B.D). The results showed that there was remarkable effect of herbicides perfect at 70 gm/ha on wide and slim leave weeds with the highest result of reducing the density of weed population. The treatment with herbicide Camix 560ec , (5 L.h-1 ) was surpassed in leaf area, leaf area index and 500 grain weight. The treatment with herbicide Perfect records the highest value in No. ears . plant -1 number of grains in a raw , number of raws , and grain . | ||
