| Abstract | ||
| Tow experiments were carried out to examine the application of GA3 and potassium fertilizer ( K2SO4 ) to increase percentage of grain protein of two varieties from barley Hordium valgare L. ( IPA 99 and 9-12 ) . The experiments were conducted during the winter seasons of 2004- 2005 and 2005- 2006 at the experimental farm / Diyala Agriculture Directorate . A split plot design was used in each experiment . Result obtained from biological interactions study showed that combination of IPA 99 variety led to lowest weed densities with compact to 12-9 genotype . and combination of GA3 with 12-9 genotype led to gained highest percentage of protein which were 11.4 and 11.6 % and lowest percentage of carbohydrate which were 68.94 and 71.55 % to first and second experiments respectively . | ||
