Abstrakt:

The availability of Mo, B and Fe is particularly important for legume plants since they live in symbiosis with bacteria in root nodules, which reduce atmospheric nitrogen to species available to plants. This field experiment was conducted to determine the content and accumulation of Mo, B and Fe by roots, stems, leaves, flowers, pods and seeds of yellow lupine. The growth phase (65 BBCH and 90 BBCH) in which the plants were harvested and the amount of nitrogen (0, 30 and 120 kg N·ha-1) introduced to the soil before sowing were the factors under study. The content of B and Fe was smaller in lupine harvested during the flowering phase (19.5 and 416.2 mg·kg-1, respectively) than after it had reached full ripeness (22.9 and 457.7 mg·kg-1, respectively). The growth phase in which lupine was harvested was found to have no effect on the content of Mo in the biomass obtained. Yellow lupine fertilised with 120 kg N·ha-1 contained less Mo and Fe compared to its cultivation with no nitrogen fertilisation and to the application of nitrogen at 30 kg N·ha-1. Different nitrogen fertilisation did not have a significant effect on the content of B in the lupine biomass. The amount of boron and iron taken up by lupine did not depend on the nitrogen fertilisation. A larger amount of Mo was taken up by lupine grown with no nitrogen fertilisation than when doses of 30 and 120 kg N·ha-1 were applied. The amount of Mo, B and Fe taken up by lupine harvested in the full ripeness phase was greater by 82%, 130% and 126%, respectively, than in the flowering phase. The greatest amount of Mo was accumulated in stems during the flowering phase and in seeds during the full ripeness phase. The greatest amounts of B and Fe were accumulated in leaves, regardless of the growth phase. The correlation coefficients calculated in the experiment did not reveal any significant relationships between the content of Mo, B and Fe in the biomass of yellow lupine and the amount of nitrogen taken up from the atmosphere.
