Abstract:
Growing demand for wheat grain with optimal technol
ogical parameters results in
looking for the possibilities of accurately meeting
the plant needs. Environmental
conditions in the surroundings of germinating grain
s can be improved by application of
humic preparations. Qualitative features of grain c
an be also changed by foliar
application of potassium, which is the activator of
enzymes catalysing synthesis of
proteins. The aim of the study was to assess the ef
fect of seed dressing with Humistar
(12%
of humic acids, 3%
fulvic acids) and foliar application of Drakar (31
% K
2
O, 3%
N)
on the spring wheat yield and qualitative features
of the grain, namely, 1,000 Kernel
Weight (TKW), Hectolitre Mass (HM), Grain Glassines
s (GG), Falling Number (FN),
total Protein Content (PC), Wet Gluten content (WG)
and Sedimentation Value (SV). The
experiment was established in the randomized blocks
design in a soil classified as Mesic
Typic Hapludalfs. The effect of the applied prepara
tions on yield was non-significant, but
it was favourable for grain quality. Application of
Humistar resulted in an improvement
of TKW, HM, GG, PC, WG and SV as compared with the
control. Results of the
application of Drakar were similar to Humistar in a
ffecting HM, WG and SV, and in the
case of PC, the result was even better. The effect
of Drakar on GG, although favourable
compared to the control, was smaller than after the
application of Humistar. Seed
dressing with Humistar or
foliar potassium fertilization with Drakar are
agrotechnical methods that can improve the qualitat
ive features of milling wheat
grain.
