has a split-split-plot design with 40 treatments
in 4 replications. Samples of winter wheat were
collected from Bicsérd, Iregszemcse,
Nagyhörcsök, Karcag and Putnok experimental
stations. Plant samples were harvested in 2004
when the weather conditions were humid.
Bicsérd is a township located in Baranya Hills,
in Hungary. The soil is chernozem brown forest
soil formed on loamy loess soils. The cultivated
layer has moderate soil moisture management.
The characteristics of the cultivated layer is the
following: pH (KCl): 5.45; CaCO 3 : 0%;
humus: 1.93%.
Iregszemcse is located in Transdanubian Hills.
The production area has typical chernozem soil
formed on slightly having clay loess sediments.
The soil moisture is balanced. The
characteristics of the cultivated layer is the
following: pH (KCl): 7.49; CaCO 3 : 10.69%;
humus: 2.69.
Nagyhörcsök is located in the Transdanubian
region of Hungary. The experimental station
has calcareous chernozem soil formed on loess.
The soil has excellent soil moisture
management. The characteristics of the
cultivated layer is the following: pH (KCl): 7.3;
CaCO 3 : 4.27%; humus: 3.45%.
Karcag is located in the Tisza floodplain in the
Great Hungarian Plain. The experimental field
has non-carbonated meadow chernozem soil
formed on infusion loess and the soil moisture
is very favorable. The characteristics of the
cultivated layer is the following: pH (KCl):
5.45; CaCO 3 : 0%; humus: 3.09%.
Putnok is located in North Hungarian
Mountains. The soil is non-podzolic forest
infiltration clay soil. The cultivated layer has
heavy water retention and low drainage,
permeability and available water resources. The
characteristics of the cultivated layer is the
following: pH (KCl): 5.00; CaCO 3 : 0%;
humus: 2.29% (Debreczeni and Németh, 2009).
The sulphur content of samples was measured
using inductively coupled plasma optical
emission spectrometer (ICP-OES) followed by
digestion with HNO 3 -H 2 O 2 solution (Kovács et
al., 1996). The protein content was determined
using Khjeldal method (MSZ 6830-4:1981).
Data analysis was done using SPSS for
Windows 13.0 Software package. All data were
subjected to ANOVA method, but after
detection of significant differences (P< 0,05)
data were subjected to Duncan’s test to allow
separation of means.
RESULTS AND DISCUSSIONS
Table 1 shows the effect of different N, P 2 O 5
and K 2 O levels on the protein and sulphur
content of winter wheat grains from the
experimental station of Bicsérd. According to
our experimental results the protein content
were higher in every NPK treatments than the
control but there were no significant effect of
the different NPK doses on the sulphur content
of kernels.
