A master's thesis at the Faculty of Agriculture discussed the effect of spraying and soaking with some microelements on the growth and yield of potatoes. The study, presented by the student Reem Mohammed Fahmi, aimed to increase the efficiency of using fertilizers for microelements iron, zinc and copper through soaking and foliar spraying and its reflection on the characteristics of vegetative growth and yield of potatoes. The study concluded that the use of the soaking experiment with microelements iron, zinc and copper fertilizers in potato fields outperformed the spraying experiment in all studied characteristics.
