Özet

The use of high-yielding cultivars that remove high amounts of potassium and micronutrients from the soil lead to potassium and micronutrients deficiencies in Turkey. An important objective for using macro and micronutrients in cotton is to balance vegetative and reproductive growth as well as to improve lint yield and fiber quality. Field study was conducted in a randomized complete block design with three replications under irrigated conditions in the Southeastern Anatolia Region of Turkey, to determine the effects of foliar potassium, zinc and micronutrient treatments on yield and fiber quality of cotton (Gossypium hirsutum L.). Compared with the untreated control, application of foliar potassium, zinc and micronutrients insignificantly affected lint turnout, seed-cotton yield, and fiber quality parameters. Furthermore, application of foliar potassium, zinc and micronutrients increased Zn2+, Cu2+, Fe3+, Mn2+, Mg2+, Na2+, Ca2+ and K+ rates in the leaf compared with the untreated control.
