| dc.description.abstract | Due to strict rules in ecological plant production, especially in
case of fertilization and plants protection, productivity i. e. yield could be
limited. Choosing the appropriate genotypes, modest requirements to the inputs
and adapted to the conditions of ecological cultivation is a particularly
important point and one of the prerequisites for economical, profitable and
stable production, without big risks and losses. The aim of this paper was to
estimate adaptability of wheat genotypes to ecological growing conditions
according to grain yield. The trial was carried out in Center for Small Grains,
Kragujevac, Serbia. 23 Serbian wheat genotypes were included. There were
applied two fertilization variants (manure and NPK fertilizers) and control
one, too. Mainly, NPK fertilizers caused statistically significant differences in
grain yield. At the same time, manure influenced the increase of grain yield
compared to the control variant. The genotypes that achieved similar yields,
without significant differences in relation to applied fertilizers, were: Morava,
Lepenica, Studenica, KG 100, Lazarica, Pobeda, Evropa 90, Perla, Pesma.
Vizija was the more yielding in manure than in NPK variant. Those varieties
are interested for practical cultivation in ecological agriculture and could be
significant material in wheat breeding in order to obtain new varieties adapted
to the ecological system of cultivation and sustainable agriculture. | sr |
