| Abstract: A field experiment was conducted in the fields of the College of Agriculture, Tikrit University for the 2019-2020 agricultural season to compare of ground and leaf additives to iron and zinc chelated fertilizers in the growth and yield of potatoes in gypsum soil. The experiment was carried out using RCBD with three replications. The study included two types of chelated fertilizers (chelated iron and chelated zinc) and two methods of adding fertilizers (adding ground and adding foliar) (T1 and T2) respectively. And three levels of zinc (0, 0.5, and 1 kg Zn h-1) (Z0, Z1, and Z2) respectively of Zn-DTPA and three levels of iron (0, 5 and 01 kg Fe h-1) (F0, F1, and F2) respectively. Arrangement of Fertilizer (Fe-DTPA). The addition of iron led to a significant increase in the dry weight of the potato shoot, as the percentage of increase compared to the control treatment was 37.79 and 25.22%, respectively, at the F1 and F2 levels, respectively. As for the fertilization method, the foliar addition T2 significantly exceeded, with a percentage increase of 10.96% compared to the ground addition, the addition of zinc gave an increase of (9.88 and 16.68)% for the levels Z1 and Z2 compared to the treatment Z0, which amounted to (48.97 gm Plant-1). The highest rate was 68.93 (gm Plant-1), while the treatments T1F0Z0 and T1F0Z0 gave the lowest rates of 37.96 and 38.14 (gm-1), respectively. The addition of iron gave a significant increase in all growth, aggregate and marketable characteristics, as it gave a total yield of tubers of (20.909, 27.512, 32.524 ton h-1) for F0, F1 and F2 levels, respectively, with a significant increase of 31.57 and 43.68%, respectively, compared to Unauthorized transaction. The foliar addition of iron gave a significant increase in the total yield of the tubers amounting to 15.10% compared to the ground addition of iron and zinc. The addition of zinc gave a significant increase in the total tuber yield of 25.82 and 43.68% for the treatments Z1 and Z2 respectively compared to the non fertilized treatment which gave a yield of (21.906 ton. h-1), the interaction between the foliar addition T2, the level of iron F2 and the level of zinc Z2 gave the highest rate (39,512 ton. h-1), while the treatments T1F0Z0 and T2F0Z0 gave the lowest rate of (15.009 and 15.033 ton. h-1(. | ||
