Effect of Potassium Fertilization Level and Miosture Stress on Growth of Wheat Plant (Triticum aestivum L.).

Abstract

Experiment was carried  out in the college of Agriculture, Unversity of Diyala during the winter season 2013-2014. The aim of study was to determine the influence of potassium levels and water stress on the growth  of wheat  (Triticum aestivum L.)  class parents of 99 for different growth stages  and to identity the sensitive  stages  to water stress.  Experiment  was carried out according to the  Randomized  Complete Block Design  (RCBD) in  Factorial experiment. The study was   consist of 12 treatment in three replicates   three levels  of  potassium fertilizer added to the soil in a form of , Potassium sulphate (0-75-150)Kg K.Ha-1  , while the  treatments of tensile  moisture , were a cut Retin non - consecutive terms in three stages ( the branch and elongation and flowering) in addition to the , control treatment with  out cut . The results of the study  recorded  increased of plant height , number of branch , leaf area and shoot  at level of Potassium fertilizer (150)7.49 cm , 27.80 branch.m2-  , 16.74 gm.plant-1 Respectively. Tensile  caused  moisture  (cut irrigation) to reduce the number of  branches in the branching stage to reduce the leaf area and shoot in the flowering stage (11.69 branch.m2- ,63.46 cm2, 49.51gm.plant1) Respectively.
