Abstract
A field experiment was conducted at the experimental farm of College of Agriculture / University of Karbala in Al- Hussania –Karbala province during winter season of 2013-2014. A split plot arrangement within Randomized Complete Block Design with three replicates was used. The aim of this experiment was to investigate the response of five wheat cultivars assigned in the subplots (Sali ,Al-Tahady, Al-Adnania, Al-fateh,and Al-Iraq) to three potassium levels (0 , 2000 , 4000 mg K.L-1) assigned in the main plots. The following Characteristics were studied plant height, number of tillers/m2، and the protein in the grains، biomass yield,and grain yield Results could be summarized as following: 1- The results showed that the Cultivars affected significantly the studied characteristics where Sali gave the highest values for plant height where Al-fateh Cultivars gave higher values for the number of spikes in square meter, concentration of protein in grains Iraq Cultivars achieved higher grain yield , While Al-Adnani cultivar gave the highest values of the concentration of yield 2– The level of 4000 mg K.L-1 gave the highest values for all Characteristics, while the level of 0 mg K. L-1 (control treatment) gave the least values of studied characteristics 3- The interactions showed different effects on the studied characteristics, The best interaction was between AL- Iraq cultivar with the level of 4000mg K.L-1 giving the highest rate of grain yield at a rate of 6670 kg /H-1. Al-Adnania also achieved better interactions with 4000 mg K.L-1of the biomass 1382 kg. H -1
