Effect of Potassium Fertilizer ,Irrigation Water Type and Foliar Application of Glycine Betaine on Some Qualitative Traits and Yield of Wheat Triticum aestivum L.


Field experiment was conducted in one of the farms of Husseiniya - Kerbala governorate duringthe agricultural season 2015-2016 to study the effect of potassium fertilization, the quality ofirrigation water and the foliar spraying with Glycine Betaine and its interferences in some qualitativetraits and yield of wheat. A factorial experiment within randomized design (CRD) in three replicateswas adopted. The first factor represents three potassium fertilizer levels (0, 75, 150) kg K. ha-1 Thesecond factor represents two types of irrigation water (river water, drainage water) and third factorrepresents three levels of foliar spraying with Glycine Betaine (0, 75, 150) mg. L-1.The results showed a significant effect of the studied factors and their interactions in contentof Glycine Betaine, total chlorophyll, proline, in the leaf of wheat and potassium concentrationpotassium to sodium ratio and protein in the grain of wheat, which was positively reflected in theincrease in grain yield1The results also showed the possibility of using the drainage water in the cultivation of wheatwhen adding potassium to the soil and foliar spraying with Glycine Betaine1
