<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">Field trial with white lupin <italic>Lupinus albus</italic> L., an anti-trypsin-free French cultivar Amiga, on heavy gleyey alluvial soil of the research base in Milhostov (alt.: 101 m, avg. year temp.: 9.0°C, year precip.: 559 mm) in the trial years of 2006-2008 was performed. The influence of three seeding rates: 0.55, 0.65, 0.75 million viable seeds per ha (MVS) and three doses of N fertilization: 25, 50, 75 kg ha-1 N on seed yield and yield components such as plant number per m2, pod number per plant, seed number per plant and thousand seed weight was tested in the trial. The data of randomized complete block design trial were statistically evaluated by ANOVA and LSD method. All tested factors had highly significant (P≤0.01) influence on seed yield. Seed yield was especially influenced by weather in year (97.8% influence), followed by seeding rate with the influence of 1.8% and N fertilization with the influence of 0.3% only. The highest seed yield of 2.21 t ha-1 was under the highest seeding rate of 0.75 MVS with the difference of 0.36 t ha-1 (19.5%) in comparison with the lowest seeding rate of 0.55 MVS (1.85 t ha-1) and about 0.15 t ha-1 (10.7%) higher in comparison with the seeding rate of 0.65 MVS (2.06 t ha-1). The highest influence on seed yield had the dose of 75 kg ha-1 N. The seed yield of 2.09 t ha-1 under the treatment with the highest dose of 75 kg ha-1 N was about 0.13 t ha-1 (6.6%) higher than the yield under the treatment with the lowest dose of 25 kg ha-1 N (1.96 t ha-1). All yield components were highly significantly (P≤0.01) influenced by weather in year. Plant number per m2 was also highly significantly (P≤0.01) influenced by all tested factors.</abstract>
