Abstract
Abstract A field experiment was conducted in sandy clay loam texture soil during the fall season 2023–2024 after looking at the efficiency of soaking potato tubers and spraying plants with some microelements (iron, zinc and copper) and their interaction in two separate experiments on the growth and yield of potatoes. Using three replicates and the Randomized Complete Block Design (R.C.B.D), the Agricultural Research and Experiment Station associated with the College of Agriculture, University of Kirkuk carried out the experiment. The soaking experiment used iron at a concentration of 200 mg L −1 in the form of ferrous sulfate, zinc at a concentration of 100 mg L −1 in the form of zinc sulfate, and copper at a concentration of 50 mg L −1 in the form of copper sulfate in different combinations. Combining these fertilizer solutions produced eight treatments, including a control one that is, without adding fertilizer). The same fertilizers iron at a concentration of 100 mg L −1 , zinc 50 mg L −1 , and copper 25 mg L −1 were added in various ratios for the spraying experiment. Adding microelements by soaking seeds and spraying plants raised plant height, leaf area, number of aerial branches, dry weight of the vegetative mass, total yield, concentration of nitrogen, phosphorous and potassium in leaves, and microelements in tubers according to statistical analysis results. Every assessed parameter the soaking experiment performed better than the spraying one. In most cases, the triple combination yielded the best results in both tests for the analyzed characteristics.
