| Title : | EFFECT OF NITROGEN FERTILIZATION IN TRITICALE (X TRITICOSECALE WITTM.), CULTIVATED AFTER DIFFERENT PREDECESSORS. NITROGEN UPTAKE AND EFFICIENCY |
| Abstract : | The study is conducted at the experimental base of Department of Plant production at Trakia University, Stara Zagora. Triticale is grown after five predecessors and different nitrogen fertilization rates. The predecessors are wintering peas, spring peas, sunflower, common wheat and triticale. Nitrogen fertilization rates are 0 (N0), 40 (N40), 80 (N80), 120 (N120) kg ha-1 after legumes and 0 (N0), 60 (N60), 120 (N120), 180 (N180) kg ha-1 after the other predecessors. The influence of the predecessors and nitrogen fertilization on the nitrogen uptake, assimilated nitrogen from fertilization, nitrogen utilization and nitrogen required for 100 kg produce of triticale is established. Nitrogen assimilation from fertilization increases with the increase of the nitrogen fertilizer rates. With the obtained yield from triticale an average of 96.53 kg ha-1 N is extracted from the soil with the grain, 18.97 kg ha-1 N with the straw or a total of 115.50 kg ha-1 N. When growing triticale after leguminous predecessors the utilization of nitrogen is 35.39% and after predecessors sunflower, wheat and triticale - 28.76%. Nitrogen required for 100 kg yield of grain of triticale is 1.9 kg of nitrogen when growing after legume predecessors and 2.8 kg of nitrogen after the other predecessors. |
