Abstract


The aim of this study was to determine the degree of copper (Cu) and manganese (Mn) uptake by pepper plants (Capsicum annuum L.) grown on four different soil types. The study was conducted in 2009 and 2010 under controlled conditions in a greenhouse. The experiment was set up according to a randomized block design with four treatments (soil types) in five replications. The results showed that the degree of Cu and Mn uptake by pepper plants was statistically significantly dependent upon the soil type used for pepper cultivation regardless of plant phenostage and year of the study. The degree of Cu uptake by pepper plants was highest in the treatment on chernozem, lower on fluvisol and pseudogley, and lowest on vertisol, while the degree of Mn uptake by pepper plants was highest on chernozem and lowest on pseudogley. The Cu content of pepper leaves in all the treatments was low as compared to related literature data irrespective of plant phenostage. Considering the potential antagonistic relationship between Cu and Mn in the soil solution, we can conclude that one of the reasons for the low copper uptake by pepper plants was the high concentration of Mn in all soil types tested.
