The influence of application of two fertilizers - nitrochalk (27% N) or ammonium nitrate sulphate (26% N, 13%S) on boron uptake and biomass production of winter oil-seed rape (var. Bristol) growing in precise field experiment was investigated. The rape plants were divided on individual parts: root, upper leaves, lower leaves, stems, branches, pods and flowers according to growing period. The field experiments were realized on fertile luvisol (Praha - Uhrineves, experimental station of Czech University of Agriculture in Prague). Treatment with application of ammonium nitrate sulphate showed higher biomass production within whole growing period in contrast to nitrochalk treatment as well yield was higher. Seed yield at nitrochalk treatment was 5.62 t/ha and yield at ammonium nitrate sulphate treatment was 6.04 t/ha. Significant influence of ammonium nitrate sulphate treatment on boron plant uptake was not observed. Maximum boron amount taken by rape 513 g/ha was determined at ammonium nitrate sulphate treatment seven days before harvest. Boron uptake by seed achieved only 10-13% of total plant boron uptake.
