Effect of Gibberellic Acid (GA3) and Potassium Fertilizer in Grain Yield for IPA Variety and 12-9 Genotype of Barley Hordium Vulgare L.
Tow experiments were carried out to examine the application of GA3 and potassium fertilizer (K2SO4) to increase grain yield of two varieties of barley (IPA 99 and 9-12). The experiments were conducted during the winter seasons of 2004- 2005 and 2005- 2006 at the experimental farm / Diyala Agricultur...

| description | Tow experiments were carried out to examine the application of GA3 and potassium fertilizer (K2SO4) to increase grain yield of two varieties of barley (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. The results of the first experiment showed that a significant increase in the number of spikes (312.6 spike / m²) and number of grain (39.0 grain / spike) with recorded increase in grain yield (3.08 ton / ha), the results of the second experiment showed that combination of GA3 + K with IPA 99 variety caused a significant increase in grain yield (4.7 ton / ha) as compared with growth regulator alone (3.74 ton / ha) or potassium fertilizer alone (3.62 ton / ha). A significant increase in the number of spikes (489.0 spikes / m²) and number of grain (42.6 grain / spike) was obtained. As a conclusion, the application of a combination of gibberellins and potassium fertilizer on barley could be used to increase the yield of grain and harvest index. |
