Abstract
An antagonistic reaction between calcium (Ca) and magnesium (Mg) and potassium (K) may lead to low absorption of K and Mg by plants from soils with high Ca contents even when levels of K and Mg should be adequate. Two separate field studies were carried out in 2009 and 2010 to determine the effects of potassium (0, 40, 80, 120 kg K2O ha−1; as potassium sulfate) and magnesium (0, 20, 40, 60 kg magnesium oxide (MgO)ha−1; as magnesium sulfate) applied to a soil with high lime content either separately or in combinations, on the grain yield and yield components of maize for grain in semi-arid Central Anatolia in Turkey. One dose of the K, Mg-fertilizers was applied during sowing in both years. According to the results, increasing the dosage of K increased yield components more than increases in Mg dosages. Combinations of K and Mg tended to maximize the yield components. Moreover, the greatest plant heights, first ear lengths, grain weights per ear and protein ratios were obtained for the K80Mg40 dose.
