| Abstract | ||||
| Snap bean have been cultivated in winter season for succulent green pods with reduced fiber and highly minerals and carbohydrates content for either exportation or local markets. The immature pods are consumed as green vegetables. It responds much better to foliar fertilizers application specially potassium (K). in this concern, two experiments were conducted to study the effect of K fertilizers sources on yield and pods quality of snap bean under clay loam soil conditions. The experiment consisted of nine sources of K fertilizers arranged in randomized complete block design with three replications. There were significant differences among most K sources in their effects on most studied parameters. The results showed that, potassium phosphite recorded the best vegetative and chemical parameters followed by potassium silicate (without significate differences between them in most cases). Also, maximum early and total green pod yield were obtained from potassium phosphite foliar application. On the other hand, maximum marketable pod yield was recorded from the application of potassium silicate. Since, the experiment was conducted in a single location and two seasons, so repeating the experiment for more locations (different soils) and other new K fertilizers could be help in drawing sound conclusive recommendations to the applied production and achieving excellent pods quality for local marketing, exportation and storage. | ||||
