Abstract

Winter wheat is an important source of mineral elements and nutrients for human beings and farm animals, and it is cultivated in one of the three largest quantities of cereals. Deficiency of mineral element intake is an alarming problem in the human diet (W<span style="font-variant:small- caps"smallhitesmall/span & B<span style="font-variant:small- caps"smallroadleysmall/span, 2005).In the present study the effect of different production sites on the contents of K, P, S, Mg, Ca, Fe, Mn, Zn, Cu, Sr and protein was investigated in whole grain and flour samples of the winter wheat (Triticum aestivum L.) cultivar Mv Csárdás. Samples were collected in the wet year of 2005 (748 mm rainfall, approx. 20% more than the longterm mean). Samples were harvested and collected from five experimental stations of the Hungarian National Long-term Fertilization Trials (OMTK), which were set up in 1966 to study the effect of different NPK levels. The selected five production sites were: Karcag, Kompolt, Iregszemcse, Nagyhörcsök and Putnok, all of which have different types of soil and climatic conditions.The element contents of the samples were measured using an inductively coupled plasma optical emission spectrometer (ICP-OES) after digestion with HNO3-H2O2 solution. The protein content was determined using the Kjeldahl method (MSz 6830-4-1981). Data analysis was carried out with the SPSS Windows 13.0 software package. During the investigation on the effect of different production sites on the element and protein content of the whole grain and flour all data were subjected to the one-way analysis of variance (ANOVA). After the detection of significant differences (P<0.05) data were subjected to the Duncan's test to allow the separation of means.The main conclusions can be drawn as followsThe statistical analysis revealed that the different production sites of the Hungarian National Long-term Fertilization Trials, such as Iregszemcse, Karcag, Kompolt and Nagyhörcsök caused significant differences in the K, P, S, Mg, Ca, Fe, Mn, Zn, Cu, Sr element (P<0.01) and protein contents (P<0.05) of the winter wheat whole grain, and in the K, P, Mg, Ca, Mn, Zn, Cu and protein contents (P<0.05) of flour samples, whereas for the flour the differences were not significant in the case of the S, Fe and Sr concentrations.The content of all the minerals was higher in the whole grain than in the flour. The whole grain includes 1.5 times as much S and protein, more than twice as much K and Cu, three times as much P and Ca, five times as much Mg, Fe and Zn and more than five times as much Sr as the flour.The study was funded in part by the KTIA-ATK-12-1-2012-0012 project.
