Abstract
Aim of this experiment was to investigate to what extent post-harvest ripening and
growing locality influenced changes of crude protein content in malting barley and
values of Kolbach index in malt. Results revealed that already in the sixth week after
harvest, amount of crude protein decreased and amount of Kolbach index increased,
due to post-harvest ripening. Moreover climatic conditions during vegetation and
harvest as well as the growing locality significantly influenced (P<0.001) the amount
of crude protein. Higher amount of crude protein was measured in barley from locality
Jakubovany which is situated in colder growing area in comparison with localities
Sládkovičovo and Veľké Ripňnany which are situated in arid growing areas.
