Abstract

The aim of the study was to evaluate the amount of nitrogen taken up from air, mineral fertilizers and soil by yellow lupine (Lupinus luteus L.) and spring triticale (Triticosecale Wittm. ex A. Camus) in their intercropping cultivation. The factor examined in the experiment was percentage of yellow lupine seeds and spring triticale grain in sown mixtures: 100/0, 75/25, 50/50, 25/75 and 0/100, respectively. Yellow lupine yield was reduced by spring triticale when intercropped. In the yield of both plants the percentage share of spring triticale grain was larger and that of yellow lupine seed was smaller than in the sown mixture. Land equivalent ratio informs that yield advantage under intercropping of lupine and triticale was minor. The total protein yield was the highest in lupine cultivation when sown pure, and decreased with increasing share of triticale in their intercropping. The mean percentage nitrogen share from N2 fixation, fertilizer and soil reserves in yellow lupine mass was: 65.2, 8.8 and 26.0%, respectively, while in the mass of spring triticale it was 10.1, 23.5 and 68.8%, respectively.
