The Effect of Foliar Application of Potassium on Some Physiological Traits of Different Wheat Cultivars (Triticum aestivum L).

In order to study the effect of potassium added Rasha in some adjectives physiological of different varieties of wheat, Triticum aestivum L., implemented a field experiment in the field trials of the Faculty of Agriculture / University of Karbala in hand Hosseinieh for the province of Karbala during the winter season 2013 – 2014 arrangement using panels dissident The split plot within the design randomized complete block (RCBD) and three replications to evaluate the performance of five varieties of wheat bread (Sally, challenge, Adnaniyah, conquest, Iraq) and that have been developed in the secondary panels. Three levels of potassium fertilization (0, 2000, and 4000 mg K. Liter -1) and placed in the main panels, and identify more closely the qualities Bhasal grain and evidence electoral promise to plant breeders in the yield of wheat (Triticum aestivum L

       Been studying a number of traits, including plant height, number of tillers / m 2, flag leaf area, the content of chlorophyll in the leaves, the water content relative estimate proline content in leaves, spike length, number of spikes, number of spikelets in the spike, the number of grains in spike, weight bead, winning bio, grain yield, harvest index, the concentration of nitrogen, phosphorus, potassium concentration, estimation of protein in the grain, the concentration of sodium, potassium and sodium to potassium ratio in grain. Analysis of variance was used to choose the less significant difference between the averages of comparable transactions and the level of significance of 5%                                                           .

      The results showed that the varieties affected significantly in traits as class Sally gave the highest values ​​of plant height and leaf area of science, the concentration of sodium in cereals. Open class and gave the highest values ​​of the number of tillers, the concentration of phosphorus in the grain, the concentration of nitrogen in the grain, the concentration of protein in the grain of the number of spikes per square meter, the number of spikelets in the spike, the number of grains in spike,. On the other hand Item Iraq achieved the highest values ​​of chlorophyll content in leaves, relative water content in leaves, proline content in the flag leaf, the proportion of sodium: potassium, spike length, kernel weight, grain yield, harvest index. While Class Adnanah gave higher values ​​for the concentration of potassium, winning bio  .

      Given the level of 4000 mg fertilization K. Liter -1 higher values ​​for all traits except proline content, sodium concentration in the grain ratio of sodium: potassium, while the level of fertilization gave 0 mg K. L-1 (control treatment) values ​​of less thoughtful recipes.

     Showed bilateral interactions influence mixed in traits, better check interference from Iraq during class with the level of fertilizer K. 4000 mg L -1 achieved the highest rate of relative water content, which amounted to (84.74%), the weight of the grain at a rate of 45.43 g, holds the grain at a rate of 6670 kg / AH-1, harvest index gave the highest rate of prescription at a rate of 54.31%, as well as achieve the best overlap regions through Iraq with the level of manure 2000 mg l -1 K. achieved the highest rate of spike length was 12.30 cm. It also achieved the best product Adnaniyah overlap with the level of manure 4000 mg L -1 K. It achieved the highest value for the concentration of potassium b highest amount of 1.853%, winning bio achieved the highest turnover amounted to 1382 kg. AH-1. While Sally has achieved the best product overlap with the level of 4000 mg compost K. liter -1 concentration of potassium in the recipe: Sodium since achieved the highest value for this trait amounted to 0.696%. While Open gave the best product overlap with the level of 4000 mg compost K. liter -1 where he achieved the highest rate in the number of spikelets spike reached 19.67, as well as for the spike in the number of grains reached 57.33 Pill

       Concludes that the growing regions of Iraq and the Open with level Samadhi higher 4000 mg K. liter -1 is an effective way to increase the quotient grain wheat, all of the efficient use of fertilizer potassium and harvest index can be adopted as a function of an election to improve grain yield to achieve the highest correlation is hereditary and my appearance with winning
