Effect of Spraying Potassium on the Growth of Vicia faba L.

The study was conducted during the 2017-2018 growing season to evaluate the responses of genotypic of (Vica faba L.) to the potassium sulfate fertilizer, Spanish (LueDeotono) and Turkish (Yildiz) with five levels from potassium were (0, 10, 20, 30, and 40 mg L -3 ). Treatments were laid down in a randomized complete block design (RCBD) with three replication , The results of this study revealed that Turkish genotypes showed significant effects in the traits plants hight, flowers number, and yield weight, in the other hand the genotype Spanish gave a high number of leaves per plant, chlorophyll content, fresh and dry weight. Application of potassium fertilizer showed significant effect gave a higher value in plant height, the number of leaves, flower number and chlorophyll content, fresh at dry weight for the stem. The interaction between the genotypic and potassium gave a higher chlorophyll, leaves number per plant, fresh at dry weight and yield weight.
