Type: article
Abstract: This study was conducted in the field of the College of Agriculture and Forestry/ University of Mosul during the spring agricultural season of 2023 to examine the effect of three irrigation systems (drip, sprinkler, and surface irrigation) and the use of a subsoil plow at depths of 25-35 cm and 35-45 cm on the potato crop. The split-plot design was used once in a Randomized Complete Block Design (RCBD) with three replications. Data were then recorded and statistically analyzed. The results were as follows: The drip irrigation system significantly outperformed in the leaf area of the plant and the yield per plant. The sprinkler irrigation system significantly outperformed in irrigation costs, while the surface irrigation significantly outperformed in pump operating time. The 35-45 cm tillage depth significantly outperformed in plant height, leaf area per plant, yield per plant, and marketable tuber yield, with an increase of 17.32%, 12.56%, 25.14%, and 12.63% respectively. The 25-35 cm tillage depth recorded the lowest significant values in operating costs and pump operating time, at 18.02% and 12.88% respectively. The interaction between drip irrigation and 35-45 cm tillage depth recorded the highest significant values in plant height, leaf area per plant, yield per plant, and marketable tuber yield, while the interaction between sprinkler irrigation and 25-35 cm tillage depth recorded the highest values in operating costs and pump operating time.
