Abstract:

Objective: In this study, bread and durum wheat grown under Cd and gyttja applications. The aim of this study was to investigate the effects of cultivars on dry matter yield, cadmium (Cd) and mineral nutrients (phosphorus, potassium, calcium, magnesium, iron, copper, zinc, manganese) intake. Materials and methods: In the greenhouse conditions, two bread (Eser and Demir) and two durum (Altın and Kızıltan) wheat varieties were carried out under 3 different Cd (0, 5 and 10 mg Cd kg-1 soil) and 4 different gyttja (0%, 2%, 4% and 8% soil) doses according to the randomized plot design in the pot experiment. At the end of the study, Cd and mineral nutrients (P, K, Ca, Mg, Fe, Cu, Zn and Mn) were measured. Results: It has been determined that there are differences in the effects of increasing doses of gyttja applications on dry matter production. Accordingly, the highest dry matter yield was obtained with 2% application of gyttja and it increased by 187% compared to the control. In the study, it was determined that there were significant differences in Cd uptake of wheat species. It was found that more Cd was transported to durum wheat varieties than bread wheat varieties. The effects of increasing doses of gyttja applications on Cd transport to wheat species were different. Accordingly, compared to the control pots, it increased the Cd concentration of bread wheats due to gyttja application, but decreased the Cd concentration of durum wheats. Depending on the gyttja applications, it was determined that there were differences in nutrient transport between wheat species. Although the uptake of P, Cu, Zn and Mn in bread wheat varieties is higher than in durum wheat, it was found that K, Ca, Mg and Fe nutrients were transported more in durum wheat varieties compared to bread wheat varieties. Conclusion: The use of gyttja applications can be recommended as it can reduce Cd transport to durum wheat in Cd polluted areas and increase the transport of mineral nutrients.
