Abstract

Kadmiyum uygulamasının toprak ve bitki mineral içeriğine ve çayır otu verimi üzerine olan etkilerini araştırmak için yürütülen bu deneyde, kadmiyumun bitkiler tarafından alınmasını etkileyen karmaşık ilişkilerin bir kısmı incelenmiştir. Araştırma sonuçları, kadmiyumun çayır otunun mineral içeriği üzerine önemli bir etkisinin bulunduğunu ve Mg ve K alımını üzerine önemli (P < 0.05) etkileri olduğunu bulmuştur. Kadmiyum uygulanan bitkilerde Mg ve K içeriklerinin verilmeyenlere göre daha düşük (P < 0.05) olduğunu göstermiştir. Her iki muamelede de çayır otunun Mg ve K içeriklerinin literatürde belirtilen minimum değerlerden düşük çıktığı, fakat magnezyumun çok daha fazla etkilendiği bulunmuştur. Kadmiyum uygulaması çayır otu verimini önemli derecede (P > 0.05) etkilememiştir.

Effects of Cadmium Application as A Heavy Metal on Mineral Content of Soil-Plant and Yield of Plant

Abstract

An experiment was carried out to investigate the effect of cadmium application on mineral content of soil and plant and cadmium effect on grass yield. This study was aimed to examine some of the complicated relationships that govern cadmium availability to the plants. The results of the research showed that cadmium (Cd) tended to have a significant effect on the mineral content of grass and cadmium (Cd) tended to significantly (P < 0.05) depress magnesium and potassium uptake by plants. The plants that had received cadmium had significantly (P < 0.05) lower content of magnesium and potassium. The magnesium and potassium contents of grass in both treatments were lower than the minimum value recommended for the mineral content of pasture in the literature, while magnesium being much more affected. Cadmium application did not significantly (P > 0.05) affect the grass yield.
