| Abstract | ||
| A pot experiment was conducted at 2013/2014 season at glass house of Soil Sc. and Water Resources Department, College of Agriculture, University of Baghdad to screen the most Zn-absorb efficient wheat varieties among four common wheat varieties. Treatments included two levels of Zn (0 and 10 kg Zn ha-1), using ZnSO4.7H2O (23%Zn), two nitrogen levels (100 and 250 kg N ha-1) using urea (46%N) applied to 4 wheat varieties (Ibaa99, Abu-Ghraib3, Bhooth 22, and Sham6) in CRD experiment. William's equation was used to evaluate the efficiency of these varieties according to their ability in Zn uptake. Results indicated that Ibaa99 and Abu-Graib3 proved to be the most prevalent Zn-efficient varieties according to different plant growth criteria's (fresh and dry weight of root and shoot, Zn uptake. Ibaa99 variety mean absorption were 0.298 µg g root fresh wt day-1 followed by Abu-Ghraib3 with 0.288 µg g root fresh wt day-1. Therefore, it can be concluded that Ibaa99 and Abu-Ghraib3 are the most efficient varieties in Zn uptake. | ||
