| Abstract | ||
| A field experiment was conducted in the fields of the College of Agriculture, Tikrit University for the 2019-2020 agricultural season to study the comparison 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 paper) (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 concentration of two elements (Fe, Zn) in potato leaves. The percentage increase of iron was 23.55 and 39.28%, for zinc, and 3.122 and 8.034% for F1 and F2 levels, respectively, compared to the F0 comparison treatment. The foliar addition of iron and zinc increased the concentration of the above elements in the tubers with rates of 19.91% and 40.45, respectively, compared to the addition of the ground. The addition of zinc at a rate of (0.5 and 1 kg Zn. h-1) significantly increased the concentration of the above elements, as the percentage of zinc increased by 36.94 and 57.53%, respectively, compared to treatment Z0, while the addition of zinc did not give a significant increase in iron concentration. The highest concentration of potato plants of the elements of iron and zinc reached 274.45 and 34.72 mg. Kg-1 when treatment T2F2Z2. The addition of iron gave a significant increase in the concentration of two elements (Fe, Zn) in potato tubers, and the percentage increase of iron was 37.65. And 70.60% for zinc, 3.114 and 4.561% for F1 and F2 levels, respectively, compared to the F0 comparison treatment. The foliar addition of iron and zinc increased the iron and zinc concentration in the tubers with rates of 15.76% and 8.240%, respectively, compared to the addition of the ground. Addition of zinc at a rate of (0.5 and 1 kg Zn.h-1) resulted in a significant increase in zinc concentration of 18.06 and 23.22%, respectively, compared to treatment Z0, while it did not give a significant increase in iron concentration. | ||
