The College of Agriculture at Tikrit University ran a field experiment for the 2022 growing season at their field crops department’s research station. According to the randomized complete block design (RCBD) with eighteen treatments and three replicates for the purpose of studying the effect of adding organic fertilizer and ground nutrition with iron and chelated zinc on the yield traits of potato plants in medium gypsum soil. The experiment included three factors, each of organic fertilizer at the level of (0,1)%, symbolized by M0 and M1, respectively, and chelated iron at three levels (0,2,4) kg.ha-1 soil, symbolized by F0, F1, and F2, respectively and chelated zinc in three levels (0,1.5,3) kg ha-1 soil, and its symbol is Z0, Z1, and Z2, respectively. The results showed that the addition of organic fertilizer, iron and chelated zinc separately led to a significant increase in the studied traits (the number of tubers per plant. tuber weight, yield per plant, total yield, and marketable yield). The interaction between organic fertilizer, iron and chelated zinc resulted in a significant increase, where the triple interaction treatment M1F2Z2 was excelled. It gave the highest values of 9.68 tuber plant-1, 130.76 g. tuber-1, 1265.76 g.plant-1, 18.892 μg ha-1, and 17.377 μg.ha-1 for the above studied traits, respectively, compared to the control treatment M0F0Z0.
