ABSTRACT

Pot experiment on yellow lupine cv. Mister covered the differentiated N_min
content in plant growth medium and methods of seed preparation for sowing, including
seed inoculation with Bradyrhizobium lupini and/or genistein. Abundance
of Nmin in the growth substrate as well as method of preparing seeds for sowing
did not affect the formation of the mean dry matter of yellow lupine plants and
their total N content. The highest dry matter of seeds per one lupine plant was
obtained with a high (calculated for field conditions 80 kg N·ha^-1)
N_min content in the growth substrate. The total N content in the aboveground
parts of plants significantly decreased since 35 days after emergence, and was
significantly the lowest at full seed maturity, while in the underground parts
the total N underwent significantly smaller changes during vegetation. The mean
N content in yellow lupine seeds did not significantly depend on the abundance
of Nmin in the growth substrate, nor on the use of seed inoculation with rhizobia
and genistein.

Key words: lupine, N₂, N_min, Bradyrhizobium lupini, genistein.
