Abstract
Determination of quantitative characteristics by using macro and microelements that have great
importance on the development of oilseed rape - Brassica napus L. started by setting the
experiment (2014), and applying Mg and Mn as elements corresponding for the purpose. The
trials were set in order to see the impact of magnesium and manganese on the quantitative
properties of winter oilseed rape genotypes - Brassica napus L.. For this purpose, certain
concentrations of magnesium sulphate and manganese chelate by foliar fertilizer application was
applied on 3 genotype winter oilseed rape (Hybrirock, Petrol and Speed) in 5 variants, as follows:
Variant 1 Control Ø NPK, Variant 2 NPK+MgSO4 25%, Variant 3 NPK+MgSO4 35%, Variant 4
NPK+Mn chelate 20%, and Variant 5 NPK+Mn chelate 30%. By specifying the appropriate
fertilizers with Mg and Mn (their concentrations), except for quantitative properties, the
adaptability of the tested genotypes of specific agro-climatic and soil conditions was observed and
the following parameters were monitored: plant height (cm), the number of branches/plant, number
of pods/plant, pod length (cm), the number of seeds in the pod and seed yield (t/ha). According to
the results of the preliminary experiment can be concluded that higher concentrations of
magnesium sulphate (35%) and manganese chelate (30%) leads to increased the components of
yield and seed in tested genotypes. Efficiency of variants, generated by certain concentrations of
fertilizers has also confirmed impact of higher concentrations; in terms of dosages and prices of
yields (NPK+Mn chelate 30% and NPK+Mg SO4 35%).
