White lupin occupies a small growing area in Poland, in spite of vast yielding potential. Increased
relevance of this species is possible thanks to spreading the determinate types and improvement
of their agrotechnology. Varieties of white lupin of determinate type are characterized by shorter
growing season, earlier and more balanced ripening and different, as compared with traditional
varieties, dynamics of gathering photoasimilates in seed yield. In years 2009-2011 strict field
experiment was conducted at the Experimental Station of Biological and Agricultural Faculty of
Rzeszów University. The goal was to specify the reaction of white lupin (Boros variety) to the
initial nitrogen feeding (ammonium nitrate 34% N) and to foliar feeding (Basfoliar 6-12-6). It was
noticed that nitrogen feeding with foliar feeding prolonged the growing season and positively
influenced crop stand before harvesting as compared with control sample. Initial nitrogen feeding
considerably increased the number of pods on a plant and mass of thousand grains, but the
number of seeds in a pod and protein content were not changed. Foliar feeding did not change
the elements of yield structure but caused a considerable 0.15% increase of protein in seeds.
Yielding of white lupin increased considerably both after initial nitrogen feeding only and after
nitrogen feeding combined with foliar feeding. The obtained difference, as compared with
control sample, was respectively 0.18 t·ha -1 and 0.26 t·ha -1 seeds.
