The influence of weather conditions, predecessors and fertilizers on the yield of brewer's barley varieties

Abstract

During the four-year study it has been established that conditions of
growing years have the greatest influence on the yield of brewer's
barley. Fertilizers are the most important controlled factors.
Provision of barley plants with fertilizers N30P30K30 leads to the
sigficant yieldincrease, regardless of its predecessor. Varieties
properties also have a significant impact. A significant interaction
between predecessors and varieties characteristics, predecessors and
fertilizers, varieties and fertilizers, the magnitude of the influence
depends on growing conditions has been established. The use of
fertilizer can increase yields of barley by 0.89–1.06 t/ha, and the use
of fertilizers Nutrivant Plus brewer’s barley results in slightly lower
yield (0.58–0.61 t/ha).Proper selection of varieties even further can
bring 0.26–0.37 t/ha.
