Evaluate the effectiveness of the weed herbicide Atlantis WG for some varieties of wheat which be approved in Iraq and associated weed and its impact on the economic quotient
AbstractA field experiment was carried out during the season 2014-2015 in the Field belongs to the college of Agriculture, Baghdad University – Jadiriyah in order to assess the effectiveness of the herbicide Atlantis WG which used to control weed wheat. Six varieties of wheat were used, namely, (Iba’a 99, Abu Ghraib 3, Fateh, Rasheed, Tahadi and Iraq). A concentration of 200 g.h?¹ and 300 g.h?¹ of herbicide was used including control line (without application). Results of the experiment revealed that, Atlantis has high efficiency in manage wheat weeds in which the density of weeds after 90 days of the application was respectively reduced as, 179.7, 67.4 plant.m?² for the two concentrations 200, 300 g.h?¹ respectively above in comparison to that of the control group which amounted of 427.7 plant.m?². Consequently, the outcomes of wheat were increased from 4.892 tans.h?¹ to 5.345 and 6.076 tans.h?¹ for the two previously mentioned concentration with percentages of 8 and 16 % respectively. Iba’a 99 class has achieved significantly the highest average with 5.860 tans.h?¹ of wheat cereals, which exceed class Abu Ghraib 3 with amount of 5.678 tans.h?¹. Such results may be attributed to the genetic variation of nature for wheat classes as well as Iba’a class has wide distance of the flag leave with 1000 grain. All of these factors may contribute to the variation of wheat class's response to the application of the herbicide. All these classes of wheat were positively responded to Atlantis WG during the application.
