Abstract

Weeds are considered one of the main challenges that hinder wheat cultivation recently as most growers claimed that no efficient method can be applied to control these plants. Thus, current study aims to increase the chemical content of wheat leaves to increase the competition with weeds and detection of selective herbicides to control it without affecting wheat crop. A field experiment was conducted in Zulele village, Babylon province during 2021-2022 season to achieve the object above. Treatments of the experiment (manual weeds removal, herbicides, seeding rate and nutrients) were arranged using randomized complete block design (R.C.B.D) with four replicates. Results showed that there were significant differences between treatments and combinations. Treatment of seeding rate amount of 180 Kg/hectare was exceeded 140 Kg/hectare. The interaction between T7 and T8 with seeding rate amount of 180 Kg/hectare was gave the highest content of nitrogen, phosphorous, potassium, the concentration of chlorophyll pigment and carotene in wheat leaves. The outcome also indicated that using Navigator or Weed free herbicides together with foliar nutrients was promoted the integrated weeds management in wheat fields.
