Abstract
This research was conducted in the field belong to the College of Agriculture and Forestry located in the tourist forest area / University of Mosul / during the autumn growing season of 2023 to show the effect of two irrigation systems: (drip irrigation system and sprinkler irrigation system) and mechanical weeding at two depths (the first depth is 4-6 cm and the second depth is 7-9 cm), then using the split-plot system once within the RCBD design with three replicates, after which the data were recorded and then statistically analyzed according to the design used. The results were as follows: The drip irrigation system led to a reduction in the number of cut bushes and a significant increase in the number of tubers per plant, the yield per plant, the total yield and the net profit compared to the sprinkler irrigation system, as the values of the above-mentioned characteristics in the superior drip irrigation system reached 27.33/m2, 6.50 tubers/plant, 1298.00 g/plant, 81.125 tons/ha and 5483.75 USD/ha. While the mechanical weeding depth of 7-9 cm was significantly superior to the mechanical weeding depth of 4-6 cm in the control percentage, yield per plant, total yield and net profit, as the values of these traits for the superior depth reached 92.00%, 1192.33 g/plant, 74.521 tons/ha and 4848.40 USD/ha respectively for each trait, while the mechanical weeding depth of 4-6 cm led to a reduction in the number of cut bushes compared to the other wedding depth. The interaction of the drip irrigation system with the mechanical weeding depth of 7-9 cm gave results in the traits of yield per plant, total yield and net profit, as the values of these traits reached 1318.33 g/plant/82.396 tons. Ha and 5589.65 USD/ha, respectively, for each trait.
